Low Prices a Problem? Making Sense of Misleading Talk about Cap-and-Trade in Europe and the USA

Posted on April 25, 2012 by Robert Stavins

Some press accounts and various advocates have labeled the Regional Greenhouse Gas Initiative (RGGI) as near “the brink of failure” because of the recent trend of very low auction prices. Likewise, commentators have recently characterized the European Union Emission Trading Scheme (EU ETS) as possibly “sinking into oblivion” because of low allowance prices. Since when are low prices (which in this case reflect low marginal abatement costs) considered to be a problem? To understand what’s going on, we need to remind ourselves of the purpose (and promise) of a cap-and-trade regime, and then look at what’s been happening in the respective markets.

The Purpose and Promise of Cap-and-Trade

A cap-and-trade system– if well designed, implemented, and enforced – will limit total emissions of the regulated pollutant to the desired level (the cap), and will do this (if the cap is binding) in a cost-effective manner, by leading regulated sources to each make reductions until they are all experiencing the same marginal abatement cost (the allowance price). Thus, the sources that initially face the highest abatement costs, reduce less, and those sources that face the lowest abatement costs, reduce more, achieving system-wide minimum costs, that is, cost effectiveness. So, the purpose and promise, in a nutshell, is to achieve the targeted level of aggregate pollution control, and – if the cap is binding – do this at the lowest possible cost.

RGGI Allowance Prices

The Regional Greenhouse Gas Initiative (RGGI) – a downstream cap-and-trade system for CO₂ emissions from the power sector in 10 northeast states (Connecticut, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Rhode Island, and Vermont, with New Jersey now in the process of withdrawing from the coalition), was launched with relatively unambitious targets, principally in order to keep prices down to prevent severe leakage of electricity demand and hence leakage of CO₂ emissions from the RGGI region to states and provinces outside of the region (mainly from New York to Pennsylvania).

Emissions are capped from 2012 to 2014, and then, starting in 2015, the cap decreases 2.5% per year until it is down by 10% in 2019. This would represent a level of emissions 13% below the 1990 level of emissions. It was originally thought that this would be some 35% below the Business-as-Usual (BAU) level in 2019. Sounds good. What happened is not that the system performed other than designed, but that “business was not as usual.” That is, what happened is that unregulated power-sector (BAU) emissions in the northeast fell significantly. (See the graph below of the RGGI cap and historical emissions.)

So, Why Did Emissions Fall in the RGGI States?

This happened for three reasons. First, because of increasing supplies in the United States of low-cost, unconventional sources of natural gas, prices for this fuel have fallen dramatically since 2008. (See the graph below of natural gas and coal prices.) That has meant greater dispatch of electricity from gas-fueled power plants (relative to coal-fired plants), more investment in new gas-fired generating plants, less investment in coal-fired generating capacity, and retirement of existing coal-fired capacity, all of which has contributed to lower CO₂ emissions.

Second, the worst economic recession since the Great Depression hit the United States in 2008, causing dramatic reductions in electricity demand in the industrial and commercial sectors, reducing emissions. (See the graph below of quarterly percentage change in U.S. GDP, 2007-2009.)

Third and finally, moderate northeast temperatures have kept down CO₂ emissions linked with both heating and cooling.

Low Emissions, Low Allowance Demand, Low Allowance Prices

So, for the three reasons above, BAU CO₂ emissions from the power sector in the RGGI states are dramatically below what was originally (and quite reasonably) anticipated. The supply of RGGI CO₂ allowances made available at auction is – by law – unchanged, but demand for these allowances has fallen dramatically, hence the fall in RGGI allowance prices. (See the graph below of RGGI allowance prices, 2008-2010.)

For source, please click here.

Given that emissions are below the RGGI cap and – due to expectations regarding future natural gas prices – are likely to remain below the cap, there is no scarcity of allowances. Shouldn’t the price fall to zero? In theory, yes, except that the system has an auction reservation price of $1.86 per ton built in, thereby creating a price floor of precisely this amount.

Is RGGI a Failure?

So, the cap put in place by the RGGI system is being achieved, but it is not binding. RGGI may not be particularly relevant, but it is not thereby a flawed system; surely it is not a failure. Rather, a great environmental success has been achieved by the “fortunate coincidence” of low natural gas prices, economic recession, and mild weather. This is hardly something to be lamented.

True enough, the RGGI system does have flaws (such as its narrow scope limited to electricity generation, and its lack of a simple safety valve, as I have written about in the past). But the low allowance prices are evidence of a success outside of the RGGI market, not evidence of failure within the RGGI market.

If the RGGI states have the desire and the political will to tighten the cap in the future, then the system can again become binding, environmentally relevant, and cost-effective. That’s an ongoing political debate.

To be fair, I should note that the same outcome I have described here can be spun – perhaps for political purposes – quite differently. Recently, a self-described “free-market energy blog” commentator claimed – not without some justification – that RGGI is irrelevant or worse: “Bottom line, the program has raised electricity prices, created a slush fund for each of the member states, and has had virtually no impact on emissions or on global climate change.”

Phrased differently, due to exogenous circumstances (I’ve described above), the RGGI program is non-binding, and so has no direct effect on emissions, but its relatively low auction reservation price does lead to very small impacts on electricity prices, and produces revenues for participating states, revenues which those states would surely claim are of value for state-level energy-efficiency and other programs that indirectly do affect CO2 emissions. So, the real bottom line is that low RGGI allowance prices are not a consequence of poor system design or a fatal flaw of cap-and-trade systems in general, but rather a consequence of what are in reality some exogenous coincidences that have turned out to be good news for the environment.

Now, let’s turn to the European Union Emissions Trading Scheme (EU ETS).

EU ETS Allowance Prices

Unlike RGGI, the EU ETS has not been irrelevant. It has successfully capped European CO₂ emissions, achieved significant emissions reductions, and it has done so — more or less — cost-effectively. (More about this hedging on cost-effectiveness below). Not surprisingly, like RGGI, the EU ETS has some design flaws (principally, its limited scope – electricity generation and large-scale manufacturing – and lack of a safety-valve), but as with RGGI, its low allowance prices should not be taken as bad news, but to some degree as good news, and certainly not as a sign of failure of the EU ETS.

Hand-wringing in Europe over Low Allowance Prices

There has been much hand-wringing in Europe over the “failure of the system” because of low allowance prices. Indeed, Danish Energy Minister Martin Lidegaard said earlier this month that low carbon prices threaten the EU ETS.

Of course, he’s correct that EU ETS allowance prices are “low.” They are down from their historic average of about $20 per ton of CO₂ to about $9 per ton currently (having reached an all-time low of $7.88 in early April). Here’s a graph of EU ETS allowance prices (EUAs) over the crucial period of change, January 2007 to January 2009.

For source, please click here.

At this point in this essay, I probably don’t need to say that this pattern is partly explained by the global recession, which has hit Europe particularly hard (and now threatens a double-dip recession in a number of European nations). Lower European – and global – demand has meant decreased economic activity in Europe, hence lower energy demand, lower CO₂ emissions, and therefore lower demand and lower prices for EU ETS allowances.

Even if we assume a growth rate of European CO₂ emissions 1 percent less than the growth rate of GDP (represented by the dotted “counterfactual” BAU line in the graph below, which estimates what emissions would have been from 2005 to 2010 without the introduction of the EU’s Emissions Trading System), the evidence makes clear that the EU ETS has succeeded in reducing emissions significantly below what would be expected from the recession alone.

For source, please click here.

This is where an important caveat needs to be introduced. Also feeding into this allowance price depression has been a set of national and regional energy policies, such as those promoting use of renewables, which have served to reduce emissions, demand for allowances, and hence allowance prices (while rendering the overall CO2 program less cost-effective by ensuring that marginal abatement costs remain heterogeneous). So, to the degree that the low allowance prices are due to so-called complimentary policies, the low prices are bad news about public policy (in cost-effectiveness terms), not good news. But this refers to misguided complimentary policies (which fail to bring about any incremental emissions reductions — under the cap-and-trade umbrella — and drive up aggregate cost), not to any design flaw in the EU ETS itself.

Multiple Goals Typically Require Multiple Policy Instruments

No doubt, Minister Lidegaard is aware of the allowance price impacts of the recession, and I hope he’s aware of the allowance price consequences of these other energy and environmental policies. The problem arises, however, because he sees the fundamental purpose of the EU ETS as somewhat broader than what I described at the beginning of this essay (namely, achieving emissions consistent with some cap, and doing so cost-effectively – if the cap is binding). For him – and many other European observers – “the purpose of the ETS was to cap CO₂ emissions in the E.U. and ensure clear economic incentives for investment in renewables.” So, the hand-wringing is not about a failure to achieve emissions reductions cost-effectively, but to have prices high enough to achieve other goals – in this case, greater use of renewable sources of energy. For others, the “other goals” have involved allowance prices high enough to bring about some targeted amount of technology innovation.

As I have written at this blog in the past, having multiple policy goals typically necessitates multiple policy instruments. For example, if the goal is a combination of reducing emissions cost-effectively and having prices maintained at some minimum (whether to bring about greater use of renewable energy sources or to inspire more technology innovation), then two policy instruments are needed to do the job: a cap-and-trade system for the first goal in combination with a carbon tax in the form of a price floor (as in RGGI) for the second goal.

Don’t Throw Out the Baby with the Bath Water

In other words, the EU ETS has not failed, but the design was inadequate (that is, incomplete) for what politicians now seem to want. If the Europeans want a price floor in their system (or better yet, a price collar, which would combine a price floor with a safety valve, i.e., price ceiling), then this is certainly feasible technically and economically. Likewise, if the EU member states have the desire and the political will to tighten the cap in the future, there are a variety of ways in which they can accomplish this, rendering the program more stringent and increasing allowances prices. But, in any event, the European Commission’s Energy division, Environment division, and Climate division should sort out the real effects of the “complimentary policies” that have contaminated the EU ETS, and which fail to bring about additional emissions reductions but drive up costs. Whether any of this is feasible politically is a question that my European colleagues and friends can best address.

If the Durban Platform Opened a Window, Will India and China Close It?

Posted on March 16, 2012 by Robert Stavins

In my December 12^th essay – following the 17^th Conference of the Parties (COP-17) of the United Nations Framework Convention on Climate Change (UNFCCC), which adjourned on December 11, 2011 – I offered my assessment of the Durban climate negotiations by taking note of three major outcomes of the negotiations: (1) elaboration on several components of the Cancun Agreements; (2) a second five-year commitment period for the Kyoto Protocol; and (3) a “non-binding agreement to reach an agreement” by 2015 that will bring all countries under the same legal regime by 2020. Subsequently, in my January 1^st essay – The Platform Opens a Window: An Unambiguous Consequence of the Durban Climate Talks – I focused on the third outcome of the talks, the “Durban Platform for Enhanced Action.”

Some Necessary History

The U.N. Framework Convention on Climate Change, adopted at the U.N. Conference on Environment and Development (the first “Earth Summit”) in Rio de Janeiro, Brazil, in 1992, contains what was to become a crucial passage: “The Parties should protect the climate system for the benefit of present and future generations of humankind, on the basis of equity and in accordance with their common but differentiated responsibilities and respective capabilities. Accordingly, the developed country Parties should take the lead in combating climate change and the adverse effects thereof.” [emphasis added] The countries considered to be “developed country Parties” were listed in an appendix to the 1992 Convention – Annex I.

The phrase – common but differentiated responsibilities – was given a specific interpretation three years after the Earth Summit by the first decision adopted by the first Conference of the Parties (COP-1) of the U.N. Framework Convention, in Berlin, Germany, April 7, 1995 – the all important Berlin Mandate, which interpreted the principle as: (1) launching a process to commit (by 1997) the Annex I countries to quantified greenhouse gas emissions reductions within specified time periods (targets and timetables); and (2) stating unambiguously that the process should “not introduce any new commitments for Parties not included in Annex I.”

Thus, the Berlin Mandate established the dichotomous distinction whereby the Annex I countries are to take on emissions-reductions responsibilities, and the non-Annex I countries are to have no such responsibilities whatsoever. This had wide-ranging and profound consequences, because it became the anchor that prevented real progress in international climate negotiations. With 50 non-Annex I countries having greater per capita income than the poorest of the Annex I countries, the distinction is clearly out of whack.

But, more important than that, this dichotomous distinction means that: (a) half of global emissions soon will be from nations without constraints; (b) the world’s largest emitter – China – is unconstrained; (c) aggregate compliance costs are driven up to be four times their cost-effective level, because many opportunities for low-cost emissions abatement in emerging economies are taken off the table; and (d) an institutional structure is perpetuated that makes change and progress virtually impossible.

The dichotomous Annex I/non-Annex I distinction remained a central – indeed, the central – feature of international climate negotiations ever since COP-1 in Berlin in 1995. Then, at COP-15 in 2009, there were hints of possible change.

The Copenhagen Accord (2009) and the Cancun Agreements (2010) began a process of blurring the Annex I/non-Annex I distinction. But this blurring was only in the context of the interim pledge-and-review system established at COP-15 in Copenhagen and certified at COP-16 in Cancun, not in the context of an eventual successor to the Kyoto Protocol. Thus, the Berlin Mandate retained its centrality.

The Durban Platform for Enhanced Action

The third of the three outcomes of the December 2011 talks in Durban, South Africa – the Durban Platform for Enhanced Action – eliminates the Annex I/non-Annex I (or industrialized/developing country) distinction. In the Durban Platform, the delegates reached a non-binding agreement to reach an agreement by 2015 that will bring all countries under the same legal regime by 2020. That’s a strange sentence, but it’s important.

Rather than adopting the Annex I/non-Annex I (or industrialized/developing country) distinction, the Durban Platform focuses instead on the pledge to create a system of greenhouse gas reductions including all Parties (that is, all key countries) by 2015 that will come into force by 2020. Nowhere in the text of the decision are phrases such as “Annex I,” “common but differentiated responsibilities,” “distributional equity,” “historical responsibility,” all of which had long since become code words for targets for the richest countries and blank checks for all others.

Thus, in a dramatic departure from some seventeen years of U.N. international negotiations on climate change, the 17^th Conference of the Parties in Durban turned away from the Annex I/non-Annex I distinction, which had been the centerpiece of international climate policy and negotiations since it was adopted at the 1^st Conference of the Parties in Berlin in 1995. In truth, only time will tell whether the Durban Platform delivers on its promise, or turns out to be another “Bali Roadmap,” leading nowhere, but there is a key unambiguous consequence of this development.

Durban Opens a Window

By replacing the Berlin Mandate, the Durban Platform has opened an important window. National delegations from around the world now have a challenging task before them: to identify a new international climate policy architecture that is consistent with the process, pathway, and principles laid out in the Durban Platform, namely to find a way to include all key countries (such as the 20 largest national and regional economies that together account for upwards of 80% of global carbon dioxide emissions) in a structure that brings about meaningful emissions reductions on an appropriate timetable at acceptable cost, while remaining within the overall framework provided by the UNFCCC.

Is India Seeking to Close the Window?

As part of the agreement to launch the Durban Platform for Enhanced Action, the nations of the world agreed to initiate a work plan on enhancing mitigation ambition. As a first step, each country was to submit its initial ideas.

On February 28, 2012, the Indian government made its official submission to the UNFCCC, “Increasing Ambition Level under Durban Platform for Enhanced Action.” In seventeen paragraphs across three pages of text, India’s submission makes absolutely clear its view that the Durban Platform is under the overall legal umbrella of the UNFCCC, and therefore that the principles of “equity” and “common but differentiated responsibilities” remain intact and must inform all commitments for enhanced action. In fact, the lion’s share of India’s submission talks about the responsibilities of industrialized countries, not about India’s ideas for its own contributions.

India’s submission actually quantifies what it sees as the necessary future commitments of Annex I (“developed”) countries – by referring to the 2007 Fourth Assessment Report (AR4) of the Intergovernmental Panel on Climate Change: “AR4 has recommended that Annex I Parties should reduce their emissions at least by 25-40% in the short term by 2020” [emphasis added]. But, in truth, AR4 made no such recommendation. Indeed, the IPCC – in general – does not make any policy recommendations whatsoever. This is one of the key organizing principles under which the IPCC operates. I know this from decades of direct work with the IPCC, having served as a Lead Author in two rounds of the IPCC, and currently serving as a Coordinating Lead Author in AR5.

China Weighs In

A week after India made its submission, the Chinese government followed suit on March 8^th with “China’s Submission on Options and Ways for Further Increasing the Level of Ambition.” The submission is consistent with India’s, maintaining that industrialized countries alone bear responsibility for reducing emissions before 2020: “Developed country Parties should take the lead in reducing their emissions by undertaking ambitious mitigation commitments and fulfill their obligations by providing financial resources and transferring technology to developing country Parties.”

They Have a Point

India and China have a point. The Durban Platform did not supplant the Convention, so the general notions of “equity” and “common but differentiated responsibilities” do remain. But – and here is the key reality – the Durban Platform did replace the Berlin Mandate. And so a window has been opened to explore new, more sophisticated, and more subtle ways of involving all key countries in an environmentally effective and cost-effective global agreement, with a new interpretation of common but differentiated responsibilities.

For example, replacing the dichotomous Annex I/non-Annex I distinction with a formula that generates a continuous spectrum of degrees of responsibility would be fully consistent both with the Durban Platform for Enhanced Action and the U.N. Framework Convention on Climate Change. Such a formulaic approach – as developed by Professors Jeffrey Frankel and Valentina Bosetti for the Harvard Project on Climate Agreements – merits serious consideration, along with other innovative international policy architectures.

Although some in the press and blogosphere have characterized the Chinese and Indian submissions as hitting “the brakes on Durban pledges” and “hitting the reset button on international climate change commitments,” in reality the Chinese and Indian submissions refer only to emission reductions prior to 2020, whereas the Durban Platform for Enhanced Action focuses on (agreeing by 2015 on) a new international agreement that would be implemented only in 2020. Thus, there’s no inconsistency.

Stay Tuned

Whether or not the submissions by China and India are part of a diplomatic dance or represent a real step backward from their positions in Durban, the fact remains that the Durban Platform – by replacing the Berlin Mandate – has opened an important window. Governments around the world need fresh, outside-of-the-box ideas over the next few years of a possible future international climate policy architecture that can meet the call of the Durban Platform while remaining true to the Framework Convention on Climate Change. That’s the challenge, as well as the opportunity.

Reflections on Twenty Years of Policy Innovation

Posted on February 3, 2012 by Robert Stavins

In 2009, the U.S. Congress considered but ultimately failed to enact legislation aimed at limiting U.S. greenhouse-gas (GHG) emissions. The bill under consideration at that time, the American Clean Energy and Security Act of 2009, was the last in a series considered over several years. Sponsored by Representatives Henry Waxman (D-California) and Edward Markey (D-Massachusetts), the bill passed the U.S. House of Representatives but failed to win sufficient support in the Senate. No legislation was enacted, and by 2010, both Congress and the White House had abandoned efforts to pass federal climate legislation.

Over months of contentious debate, while the Waxman-Markey bill and subsequent Senate action were being considered, millions of Americans were introduced for the first time to the phrase “cap and trade,” a regulatory approach that first came to prominence in the 1990s as the centerpiece of a national program to address the threat of acid rain by limiting emissions of sulfur dioxide (SO₂), primarily from electric power plants.

The 1990 SO₂cap-and-trade program was conceived by the administration of President George H. W. Bush and was widely viewed as a success. Yet cap and trade became a lightning rod for congressional opposition to climate legislation from 2009 through 2010.

Some of that hostility reflected skepticism about whether climate change was real and, if it was, whether humans played a key role in causing it. A larger group of opponents in Congress worried about the proper role of government and the costs of combating climate change, particularly given the lack of commitments for action by the large emerging economies of China, India, Brazil, Korea, South Africa, and Mexico. The congressional debate touched only lightly on the relative merits of various policy options to reduce greenhouse-gas emissions. Thus, cap and trade may not have been defeated on its merits (or demerits), but rather as collateral damage in the larger climate policy wars.

Congress (to the extent it did assess policy alternatives to cap and trade), as well as the broader community of analysts and observers in the late 2000s, raised a number of substantive questions about the merits of this policy instrument as a means for responding to a major environmental policy challenge of the sort posed by climate change:

How do the costs of a market-based approach, such as cap-and-trade, compare with traditional regulatory policies to reduce pollution?

Can market-based policies—and the markets they create—be trusted to reduce emissions? That is, are they environmentally effective?

What are the distributional impacts of market-based environmental policies; who are the winners and losers?

How well does a cap-and-trade system stimulate technological innovation, as compared with an environmental policy that sets performance standards, specifies technologies for reducing pollution, or both?

In May 2011, the Harvard Environmental Economics Program hosted a two-day research workshop and policy roundtable in Cambridge, Massachusetts, to reflect on these and other questions in light of twenty years of experience implementing the SO₂ cap-and-trade program, established under Title IV of the Clean Air Act Amendments (CAAA) of 1990. Also known as the Acid Rain Program and the SO₂ allowance-trading system, Title IV represented the first large-scale application of cap and trade to control pollution—in the United States or any other country. (Of course, the largest emissions trading program in the world is now the European Union Emissions Trading System (EU ETS), a greenhouse-gas, cap-and-trade system that was implemented in 2005 and whose design was influenced by the U.S. SO₂ program.)

A “policy brief” synthesizing the main conclusions and insights that emerged from the May 2011 Harvard workshop and roundtable has just been released, The SO₂ Allowance Trading System and the Clean Air Act Amendments of 1990: Reflections on Twenty Years of Policy Innovation. The workshop and roundtable – sponsored by the Alfred P. Sloan Foundation – featured a dream team of economists and legal experts who had conducted extensive research on the SO₂ allowance-trading system, as well as leaders of non-governmental organizations and former government officials who had guided the formulation and passage of the CAAA.

The new policy brief examines the design, enactment, implementation, and performance of the SO₂ allowance trading system, with an eye toward identifying lessons learned for future efforts to apply cap and trade to other environmental challenges, including global climate change. The first section provides background on the acid rain program and summarizes data and analysis on its benefits. Subsequent sections examine key questions regarding cost, environmental effectiveness, market performance, distributional implications, and effects on technology innovation. The report also examines the political context of the formulation, enactment, and implementation of the SO₂ allowance-trading system. Finally, the conclusions feature some reflection on implications for climate change policy.

The participants in the research workshop were: Joseph Aldy, Assistant Professor of Public Policy, Harvard Kennedy School; Dallas Burtraw, Darius Gaskins Senior Fellow, Resources for the Future; Denny Ellerman, Part-time Professor, European University Institute, Robert Schuman Centre for Advanced Studies; Michael Greenstone, 3M Professor of Environmental Economics, Massachusetts Institute of Technology; Lawrence H. Goulder, Shuzo Nishihara Professor of Environmental and Resource Economics, Stanford University; Robert Hahn, Director of Economics, Smith School, University of Oxford; Paul L. Joskow, President, Alfred P. Sloan Foundation; Erin T. Mansur, Associate Professor of Economics, Dartmouth College; Albert McGartland, Director, National Center for Environmental Economics, U.S. Environmental Protection Agency; Brian J. McLean, Former Director, Office of Atmospheric Programs, U.S. Environmental Protection Agency; W. David Montgomery, Senior Vice President, NERA Economic Consulting; Erich J. Muehlegger, Associate Professor of Public Policy, Harvard Kennedy School; Karen L. Palmer, Senior Fellow, Resources for the Future; John Parsons, Executive Director, Center for Energy and Environmental Policy Research, MIT Sloan School of Management; Forest L. Reinhardt, John D. Black Professor of Business Administration, Harvard Business School; Richard L. Schmalensee, Howard W. Johnson Professor of Economics and Management, MIT Sloan School of Management; Daniel Schrag, Sturgis Hooper Professor of Geology, Harvard University; Robert N. Stavins, Albert Pratt Professor of Business and Government, Harvard Kennedy School; Thomas Tietenberg, Mitchell Family Professor of Economics, Emeritus, Colby College; and Jonathan B. Wiener, William R. and Thomas L. Perkins Professor of Law, Duke University Law School.

The participants in the policy and politics roundtable were: Robert Grady, General Partner, Cheyenne Capital Fund (1989–1991: Associate Director, Office of Management and Budget for Natural Resources, Energy & Science; 1991–1993 Executive Associate Director, OMB, and Deputy Assistant to the President); C. Boyden Gray, Principal, Boyden Gray & Associates (1989–1993: White House Counsel); Fred Krupp, President (1984–present), Environmental Defense Fund; Mary D. Nichols, Chairman, California Air Resources Board (1993–1997: Assistant Administrator for Air and Radiation, U.S. Environmental Protection Agency); Roger Porter, IBM Professor of Business and Government, Harvard Kennedy School (1989–1993: Assistant to the President for Economic and Domestic Policy); Richard L. Schmalensee, Howard W. Johnson Professor of Economics and Management, MIT Sloan School of Management (1989–1991: Member, President’s Council of Economic Advisers); and Philip Sharp, President, Resources for the Future (1975–1995: Member, U.S. House of Representatives, Indiana, and Chairman, Energy and Power Subcommittee, House Committee on Natural Resources).

I want to acknowledge the contributions of all of these participants in the research workshop and policy roundtable, as well as the comments and edits some provided on earlier drafts of the policy brief. Their expertise and experience made this project possible. And, of course, I’m very grateful to the Alfred P. Sloan Foundation for having provided generous support for the workshop and for the preparation of the study. I hope you find it of interest and value.

Economics of the Environment

Posted on January 8, 2012 by Robert Stavins

The Sixth Edition of Economics of the Environment: Selected Readings has just been published by W. W. Norton & Company of New York and London. Through five previous editions, Economics of the Environment has served as a valuable supplement to environmental economics texts and as a stand-alone book of original readings in the field of environmental economics. Nearly seven years have passed since the previous edition of this volume was published, and it is now more than three decades since the first edition appeared, edited by Robert and Nancy Dorfman. The Sixth Edition continues this tradition.

Motivation and Audience

Environmental economics continues to evolve from its origins as an obscure application of welfare economics to a prominent field in its own right, which combines elements from public finance, industrial organization, microeconomic theory, and many other areas of economics. The number of articles on the environment appearing in mainstream economics periodicals continues to increase, and more and more economics journals are dedicated exclusively to environmental and resource topics.

There has also been a proliferation of environmental economics textbooks for college courses. Many are excellent, but none can be expected to provide direct access to timely and original contributions by the field’s leading scholars. As most teachers of economics recognize, it is valuable to supplement the structure and rigor of a text with original readings from the literature.

Scope and Style

With that in mind, this new edition of Economics of the Environment consists of thirty-four chapters that instructors will find to be of great value as a complement to their chosen text and their lectures. The scope is comprehensive, and the list of authors is a veritable “who’s who” of environmental economics, including: Joseph Aldy, Kenneth Arrow, Trudy Cameron, Ronald Coase, Maureen Cropper, Peter Diamond, George Eads, Jeffrey Frankel, Rick Freeman, Don Fullerton, Lawrence Goulder, John Graham, Robert Hahn, Michael Hanemann, Jerry Hausman, Steven Kelman, Nathaniel Keohane, Alan Krupnick, Lester Lave, John Livernois, Eric Maskin, Leonardo Maugeri, Gilbert Metcalf, Richard Newell, Roger Noll, William Nordhaus, Wallace Oates, Sheila Olmstead, Elinor Ostrom, Karen Palmer, Ian Parry, Carl Pasurka, Robert Pindyck, William Pizer, Michael Porter, Paul Portney, Forest Reinhardt, Richard Revesz, Milton Russell, Michael Sandel, Richard Schmalensee, Steven Shavell, Jason Shogren, Kerry Smith, Robert Solow, Nicholas Stern, Laura Taylor, Richard Vietor, and myself.

The articles are timely, with more than 90 percent published since 1990, and half since 2005. There are two completely new sections of the book, “Economics of Natural Resources” and “Corporate Social Responsibility,” and all of the chapters in the section on global climate change are new to the sixth edition.

In order to make the readings in Economics of the Environment accessible to students at all levels, one criterion I use in the selection process is that articles should not only be original and well written — and meet the highest standards of economic scholarship — but also be non-technical in their presentations. Hence, readers will find virtually no formal mathematics in any of the book’s 34 chapters throughout its 733 pages.

The Path Ahead

Environmental economics is a rapidly evolving field. Not only do new theoretical models and improved empirical methods appear on a regular basis, but entirely new areas of investigation open up when the natural sciences indicate new concerns or the policy world turns to new issues. Therefore, this book remains a work in progress. I owe a great debt to the teachers and students of previous editions who have sent their comments and suggestions for revisions. Looking to future editions, I invite all readers — whether teachers, students, or practitioners — to send me any thoughts or suggestions for improvement.

In the meantime, if you’re interested finding out more about the book, immediately below is a chapter-by-chapter summary of the book. Alternatively, you can check out the W. W. Norton or Amazon web sites.

Appendix: A Summary of Economics of the Environment, Sixth Edition

Part I of the volume provides an overview of the field and a review of its foundations. Don Fullerton and I start things off with a brief essay about how economists think about the environment (Nature 1998). This is followed by the classic treatment of social costs and bargaining by Ronald Coase (Journal of Law and Economics 1960), and a new article by Jason Shogren and Laura Taylor on the important, emerging field of behavioral environmental economics (Review of Environmental Economics and Policy 2008).

The Costs of Environmental Protection

Part II examines the costs of environmental protection, which might seem to be without controversy or current analytical interest. This is not, however, the case. This section begins with a survey article by Carl Pasurka that reviews the theory and empirical evidence on the relationship between environmental regulation and so-called “competitiveness” (Review of Environmental Economics and Policy 2008).

A somewhat revisionist view is provided by Michael Porter and Class van der Linde, who suggest that the conventional approach to thinking about the costs of environmental protection is fundamentally flawed (Journal of Economic Perspectives 1995). Karen Palmer, Wallace Oates, and Paul Portney provide a careful response (Journal of Economic Perspectives 1995).

The Benefits of Environmental Protection

In Part III, the focus turns to the other side of the analytic ledger — the benefits of environmental protection. This is an area that has been even more contentious — both in the policy world and among scholars. Here the core question is whether and how environmental amenities can be valued in economic terms for analytical purposes.

The book features a provocative debate on the stated-preference method known as “contingent valuation.” Paul Portney outlines the structure and importance of the debate, Michael Hanemann makes the affirmative case, and Peter Diamond and Jerry Hausman provide the critique (all three articles are from the Journal of Economic Perspectives 1994).

In the final article in Part III, the book turns to a concept that is both very important in assessments of the benefits of environmental regulations and is also very widely misunderstood — the value of a statistical life. In an insightful essay, Trudy Cameron seeks to set the record straight (Review of Environmental Economics and Policy 2010).

There are two principal policy questions that need to be addressed in the environmental realm: how much environmental protection is desirable; and how should that degree of environmental protection be achieved. The first of these questions is addressed in Part IV and the second in Part V.

The Goals of Environmental Policy: Economic Efficiency and Benefit-Cost Analysis

In an introductory essay, Kenneth Arrow, Maureen Cropper, George Eads, Robert Hahn, Lester Lave, Roger Noll, Paul Portney, Milton Russell, Richard Schmalensee, Kerry Smith, and I ask whether there is a role for benefit-cost analysis to play in environmental, health, and safety regulation (Science 1996).

Then, Lawrence Goulder and I focus on an ingredient of benefit-cost analysis that non-economists seem to find particularly confusing, or even troubling — intertemporal discounting (Nature 2002). Next, Robert Pindyck examines a subject of fundamental importance — the role of uncertainty in environmental economics (Review of Environmental Economics and Policy 2007). Steven Kelman provides an ethically-based critique of benefit-cost analysis, which is followed by a set of responses (Regulation 1981).

Part IV concludes with an up-to-date essay by John Graham on the critical role of the U.S. Office of Management and Budget in federal regulatory impact analysis (Review of Environmental Economics and Policy 2008).

The Means of Environmental Policy: Cost Effectiveness and Market-Based Instruments

Part V examines the policy instruments — the means — that can be employed to achieve environmental targets or goals. This is an area where economists have made their greatest inroads of influence in the policy world, with tremendous changes having taken place over the past twenty years in the reception given by politicians and policy makers to so-called market-based or economic-incentive instruments for environmental protection.

Lawrence Goulder and Ian Parry start things off with a broad-ranging essay on instrument choice in environmental policy (Review of Environmental Economics and Policy 2008). Following this, I examine lessons that can be learned from the innovative sulfur dioxide allowance trading program, set up by the Clean Air Act Amendments of 1990 (Journal of Economic Perspectives 1998). Finally, Michael Sandel provides a critique of market-based instruments, with responses offered by Eric Maskin, Steven Shavell, and others (New York Times 1997).

Economics of Natural Resources

Part VI consists of three essays on a new topic for this book — the economics of natural resources. First, John Livernois examines the empirical significance of a central tenet in natural resource economics, namely the Hotelling Rule — the proposition that under conditions of efficiency, the scarcity rent (price minus marginal extraction cost) of natural resources will rise over time at the rate of interest (Review of Environmental Economics and Policy 2009).

Essays by Leonardo Maugeri (Review of Environmental Economics and Policy 2009) and Sheila Olmstead (Review of Environmental Economics and Policy 2010), respectively, examine two particularly important resources: petroleum and water.

The next four sections of the book treat some timely and important topics and problems.

Corporate Social Responsibility and the Environment

Part VII examines corporate social responsibility and the environment, discussion of which has too often been characterized by more heat than light. Forest Reinhardt, Richard Vietor, and I provide an overview of this realm from the perspective of economics, examining the notion of firms voluntarily sacrificing profits in the social interest. In a second essay, Paul Portney provides a valuable empirical perspective (both are from the Review of Environmental Economics and Policy 2008).

Global Climate Change

Part VIII is dedicated to investigations of economic dimensions of global climate change, which may in the long term prove to be the most significant environmental problem that has arisen, both in terms of its potential damages and in terms of the costs of addressing it. First, a broad overview of the topic is provided in a survey article by Joseph Aldy, Alan Krupnick, Richard Newell, Ian Parry, and William Pizer (Journal of Economic Literature 2010).

Next, William Nordhaus critiques the well-known Stern Review on the Economics of Climate Change, and Nicholas Stern and Chris Taylor respond (both are from Science 2007). In the final essay in this section, Gilbert Metcalf examines market-based policy instruments that can be used to address greenhouse gas emissions (Journal of Economic Perspectives 2009).

Sustainability, the Commons, and Globalization

Part IX begins with Robert Solow’s economic perspective on the concept of sustainability. This is followed by Elinor Ostrom’s development of a general framework for analyzing sustainability (Science 2009), and my own historical view of economic analysis of problems associated with open-access resources (American Economic Review 2011). Then, Jeffrey Frankel draws on diverse sources of empirical evidence to examine whether globalization is good or bad for the environment (Council on Foreign Relations 2004).

Economics and Environmental Policy Making

The final section of the book, Part X, departs from the normative concerns of much of the volume to examine some interesting and important questions of political economy. It turns out that an economic perspective can provide useful insights into questions that might at first seem to be fundamentally political.

Nathaniel Keohane, Richard Revesz, and I utilize an economic framework to ask why our political system has produced the particular set of environmental policy instruments it has (Harvard Environmental Law Review 1998). Myrick Freeman reflects on the benefits that U.S. environmental policies have brought about since the first Earth Day in 1970 (Journal of Economic Perspectives 2002). Lastly, Robert Hahn addresses the question that many of the articles in this volume raise: what impact has economics actually had on environmental policy (Journal of Environmental Economics and Management 2000)?

The Platform Opens a Window: An Unambiguous Consequence of the Durban Climate Talks

Posted on January 1, 2012 by Robert Stavins

In my previous essay – following the 17^th Conference of the Parties (COP-17) of the United Nations Framework Convention on Climate Change (UNFCCC), which adjourned on December 11, 2011 – I offered my assessment of the Durban climate negotiations, addressing the frequently-posed question of whether the talks had “succeeded.” I took note of three major outcomes from the negotiations: (1) elaboration on several components of the Cancun Agreements; (2) a second five-year commitment period for the Kyoto Protocol; and (3) a non-binding agreement to reach an agreement by 2015 that will bring all countries under the same legal regime by 2020. My conclusion was that this package – in total – represented something of a “half-full glass of water,” that is, an outcome that could be judged successful or not, depending upon one’s perspective.

However, something I did not discuss last month is that this third provision – the “Durban Platform for Enhanced Action” – has opened an important window. To explain what I mean requires a brief review of some key points from twenty years of history of international climate negotiations.

The Rio Earth Summit (1992)

The U.N. Framework Convention on Climate Change, adopted at the U.N. Conference on Environment and Development (the first “Earth Summit”) in Rio de Janeiro, Brazil, in 1992, contains what was to become a crucial passage. The first “principle” in Article 3 of the Convention reads as follows: “The Parties should protect the climate system for the benefit of present and future generations of humankind, on the basis of equity and in accordance with their common but differentiated responsibilities and respective capabilities. Accordingly, the developed country Parties should take the lead in combating climate change and the adverse effects thereof.” [emphasis added] The countries considered to be “developed country Parties” were listed in an appendix to the 1992 Convention – Annex I.

The phrase – common but differentiated responsibilities – has been repeated countless numbers of times since 1992, but what does it really mean? The official answer was provided three years after the Earth Summit by the first decision adopted by the first Conference of the Parties (COP-1) of the U.N. Framework Convention, in Berlin, Germany, April 7, 1995 – the Berlin Mandate.

The Berlin Mandate (1995)

The Berlin Mandate interpreted the principle of “common but differentiated responsibilities” as:

(1) launching a process to commit (by 1997) the Annex I countries to quantified greenhouse gas emissions reductions within specified time periods (targets and timetables); and

(2) stating unambiguously that the process should “not introduce any new commitments for Parties not included in Annex I.”

The Kyoto Protocol (1997)

It was in direct response to this Mandate that the U.S. Senate subsequently passed unanimously (95-0) the Byrd-Hagel Resolution in August of 1997 (Senate Resolution 98, 105^th Congress, 1^st Session) stating that:

“It is the sense of the Senate that the United States should not be a signatory to any protocol to, or other agreement regarding, the United Nations Framework Convention on Climate Change of 1992, at negotiations in Kyoto in December 1997, or thereafter, which would mandate new commitments to limit or reduce greenhouse gas emissions for the Annex I Parties, unless the protocol or other agreement also mandates new specific scheduled commitments to limit or reduce greenhouse gas emissions for Developing Country Parties within the same compliance period.”

So, in a very real sense, the Berlin Mandate brought about sustained bi-partisan opposition in the United States to the international climate regime and the Kyoto Protocol. This sealed the Protocol’s fate in terms of ever being ratified by the U.S. Senate. President Clinton did not submit the Protocol to the Senate for ratification, nor would Al Gore have done so had he been elected to succeed Clinton. Likewise, Senator John Kerry was explicit about his opposition to Kyoto when he ran for President against George W. Bush, and President Bush was subsequently more than explicit about his lack of support for the Protocol and, for that matter, the UNFCCC process. When Barack Obama ran against John McCain for President in 2008, one thing on which they agreed was their opposition to the Kyoto Protocol.

Beyond those decisive impacts on U.S. climate politics, the Berlin Mandate had wide-ranging and worldwide normative consequences, because it became the anchor that prevented and has – until very recently – continued to prevent real progress in international climate negotiations. With 50 non-Annex I countries having greater per capita income than the poorest of the Annex I countries, the distinction is clearly out of whack. But, more important than that, this dichotomous distinction means that:

(a) half of global emissions soon will be from nations without constraints;

(b) the world’s largest emitter – China – is unconstrained;

(c) aggregate compliance costs are driven up to be four times their cost-effective level, because many opportunities for low-cost emissions abatement in emerging economies are taken off the table; and

(d) an institutional structure is perpetuated that makes change and progress virtually impossible.

Fast Forward to Copenhagen (2009) and Cancun (2010)

The Copenhagen Accord (2009) and the Cancun Agreements (2010) began a process of blurring the Annex I/non-Annex I distinction. However, this blurring was only in the context of the interim pledge-and-review system established at COP-15 in Copenhagen and certified at COP-16 in Cancun, not in the context of an eventual successor to the Kyoto Protocol. Thus, the Berlin Mandate retained its centrality.

Finally, We Arrive in Durban (2011)

The third of the three outcomes of the December 2011 talks in Durban, South Africa, which I mentioned at the beginning of this essay – the Durban Platform for Enhanced Action – completely eliminates the Annex I/non-Annex I (or industrialized/developing country) distinction. In the Durban Platform, the delegates reached a non-binding agreement to reach an agreement by 2015 that will bring all countries under the same legal regime by 2020. That’s a strange and confusing sentence, but it’s what happened, and it’s potentially important.

Rather than adopting the Annex I/non-Annex I (or industrialized/developing country) distinction, the Durban Platform focuses instead on the (admittedly non-binding) pledge to create a system of greenhouse gas reductions including all Parties (that is, all key countries) by 2015 that will come into force (after ratification) by 2020. Nowhere in the text of the decision will one find phrases such as “Annex I,” “common but differentiated responsibilities,” “distributional equity,” “historical responsibility,” all of which had long since become code words for targets for the richest countries and blank checks for all others.

A Dramatic Departure

Thus, in a dramatic departure from some seventeen years of U.N. hosted international negotiations on climate change, the 17^th Conference of the Parties in Durban turned away from the Annex I/non-Annex I distinction, which had been the centerpiece of international climate policy and negotiations since it was adopted at the 1^st Conference of the Parties in Berlin in 1995.

Because of this, the international law scholar, Daniel Bodansky, has labeled “the Durban Platform a complete departure from the Berlin Mandate.” Likewise, Indian professor of international law, Lavanya Rajamani says that Durban delivered a “new process and with it, a clean slate on differentiation.” And Elliot Diringer of the Center for Climate and Energy Solutions, finds the overall Durban deal to be “delicately poised between two eras – the fading age of Kyoto, and a new phase … with developed and developing countries presumably on a more equal footing.”

This is of vast potential importance, but – of course – only “potential” importance, because just as it was the Kyoto Protocol’s numerical targets and timetables that fulfilled the Berlin Mandate’s promise, it remains for the delegates to the UNFCCC to meet this Durban mandate with a new post-Kyoto agreement by 2015 (to come into force by 2020). Only time will tell whether the Durban Platform delivers on its promise, or turns out to be another “Bali Roadmap,” leading nowhere.

So, with such uncertainty, what’s the “unambiguous consequence” of Durban that I refer to in the title of this essay?

An Unambiguous Outcome: The Platform Opens a Window

The Durban Platform – by replacing the Berlin Mandate – has opened an important window. It is this. The national delegations from around the world now have a challenging task before them: to identify a new international climate policy architecture that is consistent with the process, pathway, and principles laid out in the Durban Platform, namely to find a way to include all key countries (such as the 20 largest national and regional economies that together account for upwards of 80% of global carbon dioxide emissions) in a structure that brings about meaningful emissions reductions on an appropriate timetable at acceptable cost.

Having broken the old mold, a new one must be forged. There is a mandate for change. Governments around the world now need fresh, outside-of-the-box ideas from the best thinkers, and they need those ideas over the next few years. This is a time for new proposals for future international climate policy architecture, not for incremental adjustments to the old pathway. I trust that this call will be heard by a diverse set of universities, think tanks, and – for that matter – advocacy and interest groups around the world. With 48 research initiatives in Australia, China, Europe, India, Japan, and the United States, the Harvard Project on Climate Agreements is prepared to contribute to this effort. Please stay tuned.

Assessing the Climate Talks — Did Durban Succeed?

Posted on December 12, 2011 by Robert Stavins

The 17^th Conference of the Parties (COP-17) of the United Nations Framework Convention on Climate Change (UNFCCC) adjourned on Sunday, a day and a half after its scheduled close, and in the process once again pulled a rabbit out of the hat by saving the talks from complete collapse (which appeared possible just a few days earlier). But was this a success?

The Durban Outcome in a Nutshell

The outcome of COP-17 includes three major elements: some potentially important elaborations on various components of the Cancun Agreements; a second five-year commitment period for the Kyoto Protocol; and (read this carefully) a non-binding agreement to reach an agreement by 2015 that will bring all countries under the same legal regime by 2020.

Is This a Success?

If by “success” in Durban, one means solving the climate problem, the answer is obviously “not close.”

Indeed, if by “success” one meant just putting the world on a path to solve the climate problem, the answer would still have to be “no.”

But, I’ve argued previously – including in my pre-Durban essay last month – that such definitions of success are fundamentally inappropriate for judging the international negotiations on the exceptionally challenging, long-term problem of global climate change.

The key question, at this point, is whether the Durban outcome has put the world in a place and on a trajectory whereby it is more likely than it was previously to establish a sound foundation for meaningful long-term action.

I don’t think the answer to that question is at all obvious, but having read carefully the agreements that were reached in Durban, and having reflected on their collective implications for meaningful long-term action, I am inclined to focus on “the half-full glass of water.” My conclusion is that the talks – as a result of last-minute negotiations – advanced international discussions in a positive direction and have increased the likelihood of meaningful long-term action. Why do I say this?

The Significance of Durban

Let’s look at the three major elements of the Durban outcome.

1. Putting More Flesh on the Bones of the Cancun Agreements

First, the delegates agreed to a set of potentially important details on various components of the Cancun Agreements. This progress may turn out to be very important indeed, and helps advance – at least for the interim – a workable bottom-up, pledge-and-review approach to international climate cooperation. The progress on this front includes work done on the Green Climate Fund to help mobilize public and private funding of climate change mitigation and adaptation in developing countries; more specifics on technology transfer mechanisms; mechanisms to enhance the transparency of national commitments under the Cancun Agreements; and an international scheme to reduce deforestation, which – importantly – includes market mechanisms.

2. A Second Commitment Period for the Kyoto Protocol

Second, the delegates agreed to a second five-year commitment period for the Kyoto Protocol. Without this element, the talks would have collapsed, because the key emerging economies of China, India, Brazil, South Africa, Korea, and Mexico (not to mention the much larger number of truly poor, developing countries) would have walked out. Would this have been so bad?

I have long argued that the Kyoto Protocol – with its structure of relatively ambitious targets for a small set of industrialized countries (the Annex I countries) and no targets whatsoever for the much larger set of other nations in the world (the non-Annex I countries) – is fundamentally flawed as a basis for addressing the climate change problem in a meaningful way, that is, in a way that can eventually limit global temperature increases to no more than 2 or 3 degrees Centigrade above pre-industrial levels. In the past, some observers have gone so far as to argue that such a collapse of the talks would be necessary to free the world to consider alternative and ultimately more productive routes going forward. Eventually, that may turn out to be true, but extending the Kyoto Protocol at this time for another period does little mischief.

The major effect – in addition to keeping the emerging economies (and developing countries) from walking out of the room – was to place the European Union in a position of accepting a target (for a second five-year period) that is no more stringent than what it has already committed to do under the European Union Emission Trading Scheme (EU ETS). The United States is not a party to the Kyoto Protocol, and Canada, Japan, and Russia have indicated that they will not take up targets in a second commitment period. Europe (and New Zealand, and possibly Australia) will be doing what they would have done anyway. In exchange for this, the major emerging economies agreed to the third key element.

3. The Durban Platform for Enhanced Action

Third and finally, the delegates reached a non-binding agreement to reach an agreement by 2015 that will bring all countries under the same legal regime by 2020. That’s a strange and confusing sentence, but it’s what happened, and – in my opinion – it’s potentially important, although it’s much too soon to say for sure.

The anchor that has been preventing real progress in the international climate negotiations for the past fifteen years has been the Kyoto Protocol’s dichotomous distinction between Annex I and non-Annex I countries. With 50 non-Annex I countries now having greater per capita income than the poorest of the Annex I countries, it is clearly out of whack. But, much more than that, this dichotomous distinction means that the world’s largest emitter – China – is unconstrained, that half of global emissions soon will be from nations without constraints, it drives up costs to four times their cost-effective level, and it creates a structure that makes change and progress virtually impossible.

Fortunately, the Copenhagen Accord and the Cancun Agreements began the process of blurring the Annex I/non-Annex I distinction, which was an important accomplishment, although it was only in the context of the interim pledge-and-review system, not in the context of an eventual successor to Kyoto. Now, the COP-17 decision for “Enhanced Action” completely eliminates the Annex I/non-Annex I (or industrialized/developing country) distinction. It focuses instead on the (admittedly non-binding) pledge to create a system of greenhouse gas reductions including all Parties (that is, all key countries) by 2015 that will come into force (after ratification) by 2020. Nowhere in the text of the decision will one find phrases such as “Annex I,” “common but differentiated responsibilities,” or “distributional equity,” which have – in recent years – become code words for targets for the richest countries and a blank check for all others.

We should not over-estimate the importance of a “non-binding agreement to reach a future agreement,” but this is a real departure from the past, and marks a significant advance along the treacherous, uphill path of climate negotiations.

The Path Ahead

In my previous essay at this blog, I expressed the fear that contentious debates over a possible second commitment period for the Kyoto Protocol might disrupt the Durban talks, divert them from making sound progress on the Cancun structure, and keep the delegates from moving toward a sound foundation for meaningful long-term action. I worried, in essence, that Durban – despite the weather – might resemble Copenhagen more than Cancun.

My conclusion is that this did not happen. Not only did Durban not undo the progress made in Cancun, it built upon it, and moved forward. This won’t satisfy the 350.org crowd, and it must greatly annoy the opponents of sensible climate policy, but in the real world of international negotiations on this exceptionally difficult global commons problem, this is what success looks like.

Can the Durban Climate Negotiations Succeed?

Posted on November 28, 2011 by Robert Stavins

Two weeks of international climate negotiations begin today in Durban, South Africa. These are the Seventeenth Conference of the Parties (COP-17) of the United Nations Framework Convention on Climate Change (UNFCCC). The key challenge at this point is to maintain the process of building a sound foundation for meaningful, long-term global action, not necessarily some notion of immediate, highly-visible triumph. In other words, the answer to the question of whether the Durban climate negotiations can succeed depends — not surprisingly — on how one defines “success.”

Let’s Place the Climate Negotiations in Perspective

Why do I say (repeatedly, year after year) that the best goal for the climate talks is to make progress on a sound foundation for meaningful, long-term global action, not some notion of immediate triumph? The reason is that the often-stated cliche about the American baseball season — that it’s a marathon, not a sprint — applies even more so to international climate change policy. Why?

First, the focus of scientists (and policy makers) should be on stabilizing concentrations at acceptable levels by 2050 and beyond, because it is the accumulated stock of greenhouse gas emissions — not the flow of emissions in any year — that are linked with climate consequences.

Second, the cost-effective path for stabilizing concentrations involves a gradual ramp-up in target severity, to avoid rendering large parts of the capital stock prematurely obsolete.

Third, massive technological change is the key to the needed transition from reliance on carbon-intensive fossil fuels to more climate-friendly energy sources. Long-term price signals (most likely from government policies) will be needed to inspire such technological change.

Fourth and finally, the creation of long-lasting international institutions is central to addressing this global challenge.

For all of these reasons, international climate negotiations will be an ongoing process, not a single task with a clear end-point. Indeed, we should not be surprised that they proceed much as international trade talks do, that is, with progress only over the long term, building institutions (the GATT, the WTO), yet moving forward in fits and starts, at times seeming to move backward, but with progress in the long term.

So, the bottom-line is that a sensible goal for the international negotiations in Durban is progress on a sound foundation for meaningful long-term action, not some notion of immediate “success.” This does not mean that there should be anything other than a sense of urgency associated with the work at hand, because it is important. But it does mean that we should keep our eyes on the prize.

How Can the Durban Negotiators Keep their Eyes on the Prize?

The keys to success — real, as opposed to symbolic success — in Durban depend upon four imperatives.

1. Embrace Parallel Processes

The UNFCCC process must embrace the parallel processes that are carrying out multilateral discussions (and in some cases, negotiations) on climate change policy: the Major Economies Forum or MEF (a multilateral venue for discussions – but not negotiations – outside of the UNFCCC, initiated under a different name by the George W. Bush administration in the United States, and continued under a new name by the Obama administration, for the purpose of bringing together the most important emitting countries for candid and constructive discussion and debate); the G20 (periodic meetings of the finance ministers – and sometimes heads of government – of the twenty largest economies in the world); and various other multilateral and bilateral organizations and discussions.

The previous leadership of the UNFCCC seemed to view the MEF, the G20, and most other non-UNFCCC forums as competition – indeed, as a threat. Fortunately, the UNFCCC’s new leadership under Executive Secretary Christiana Figueres (appointed by UN Secretary-General Ban Ki-moon in May of 2010) has displayed a considerably more positive and pragmatic attitude toward these parallel processes. That’s a positive sign.

2. Consolidate Negotiation Tracks

There are now three major, parallel processes operative: first, the UNFCCC’s KP track (negotiating national targets for a possible second commitment period – post-2012 – for the Kyoto Protocol); second, the LCA track (the UNFCCC’s negotiation track for Long-term Cooperative Action, that is, a future international agreement of undefined nature); and third, the Cancun Agreements from COP-16 a year ago (based upon the Copenhagen Accord, negotiated and noted at COP-15 in Copenhagen, Denmark, in December, 2009). Consolidating these three tracks into two tracks (or better yet, one track) would be another significant step forward.

The primary way for this to happen would be for the LCA negotiations to focus on the ongoing work of putting more meat on the bones of the Cancun Agreements, which — along with the Copenhagen Accord — marked an important step forward by blurring for the first time (although not eliminating) the unproductive and utterly obsolete distinction in the Kyoto Protocol between Annex I and non-Annex I countries. (Note that more than 50 non-Annex I countries have greater per capita income than the poorest of the Annex I countries.)

In particular, the UNFCCC principle of “common but differentiated responsibilities” could be made meaningful through the dual principles that: all countries recognize their historic emissions (read, the industrialized world); and all countries are responsible for their future emissions (think of the rapidly-growing, large, emerging economies of China, India, Brazil, Korea, Mexico, and South Africa).

As I’ve said before, this would represent a great leap beyond what has become the “QWERTY keyboard” (that is, unproductive path dependence) of international climate policy: the distinction in the Kyoto Protocol between the small set of Annex I countries with quantitative targets, and the majority of countries in the world with no responsibilities. A variety of policy architectures — including but not limited to the Cancun Agreements — could build on these dual principles and make them operational, beginning to bridge the massive political divide that exists between the industrialized and the developing world.

At the Harvard Project on Climate Agreements — a multi-national initiative with some 35 research projects in Australia, China, Europe, India, Japan, and the United States — we have developed a variety of architectural proposals that could make these dual principles operational. (See, for example: “Global Climate Policy Architecture and Political Feasibility: Specific Formulas and Emission Targets to Attain 460 PPM CO2 Concentrations” by Valentina Bosetti and Jeffrey Frankel; and “Three Key Elements of Post-2012 International Climate Policy Architecture” by Sheila M. Olmstead and Robert N. Stavins.)

3. Make Progress on Narrow, Focused Agreements

A third area of success at the Durban negotiations could be realized by some productive steps with specific, narrow agreements, such as on REDD+ (Reduced Deforestation and Forest Degradation, plus enhancement of forest carbon stocks). Other areas where talks are moving forward, although somewhat more slowly, are finance and technology, particularly in the context of adding meat to the bones of the Cancun Agreements.

4. Maintain Sensible Expectations

Finally, it is important to go into these annual negotiations with sensible expectations and thereby effective plans. As I said at the outset, negotiations in this domain are an ongoing process, not a single task with a clear end-point. The most sensible goal for Durban is progress on a sound foundation for meaningful long-term action, not some notion of immediate triumph. The key question is not what Durban accomplishes in the short-term, but whether it helps put the world in a better position five, ten, and twenty years from now in regard to an effective long-term path of action to address the threat of global climate change.

Wait, What About the Kyoto Protocol?

Those who follow these international negotiations closely — including my colleagues on the ground in Durban — are no doubt wondering why I haven’t said something about the 900-pound gorilla in the closet: the fact that the Kyoto Protocol’s first (and so far only) commitment period runs from 2008 through 2012, and so a decision needs to be reached on a possible second (post-2012) commitment period for the Protocol.

Yes, in addition to the LCA (Cancun) track, the Kyoto Protocol (KP) track of negotiations remains. A decision regarding a possible extension (and presumably an enhancement) of the Kyoto Protocol’s emission-reduction targets for the industrialized (Annex I) countries has been punted annually to the next set of negotiations — from Bali in 2007, to Poznan in 2008, to Copenhagen in 2009, to Cancun in 2010, and now to Durban in 2011. It can’t be delayed any longer, because the necessary process of ratification by individual nations would itself take at least a year to complete.

Keeping the Kyoto Protocol going (and with more stringent targets for the Annex I countries) is very important to the non-Annex I countries, sometimes referred to — inaccurately — as the developing countries. I don’t blame them. An approach that provides benefits (reduced climate damages, as well as financial transfers) for the non-Annex I countries without their incurring any costs is surely an attractive route for those nations.

Is a Second Commitment Period for the Kyoto Protocol Feasible?

Putting aside the possible merits of a second commitment period for the Kyoto Protocol, we can ask simply whether it’s in the cards: is it feasible?

Japan, Russia, and Canada have formally announced that they will not take up targets in a second commitment period. Australia, despite its recent domestic climate policy action, seems unlikely to make a significant commitment. Is Europe (plus New Zealand) on its own credible or feasible? Maybe yes, maybe no.

The “yes” part of the answer comes from the fact that Europe has already committed itself to serious emissions reductions through the year 2020 under the European Union Emission Trading Scheme (EU ETS). This will go forward — barring a change of heart by the EU — with or without a second commitment period for the Kyoto Protocol. That said, Europe’s compliance costs under the EU ETS will be much less than otherwise if offsets continue to be made available from non-Annex I countries under the Kyoto Protocol’s Clean Development Mechanism (CDM). This might suggest that the EU has a significant motivation to keep the Kyoto Protocol going.

But international law scholars — such as Professor Daniel Bodansky of Arizona State University‘s Sandra Day O’Connor College of Law — maintain that the Kyoto Protocol (and its CDM) continues as an institution of law whether or not a second commitment period is put in place. Hence, it’s conceivable that the EU could have its cake and eat it too: an ongoing Kyoto Protocol without a second commitment period. And the political pressure on Brussels from the EU’s member states — and from European businesses — might make it difficult for the EU to sign up for a new series of commitments given the obvious absence in such an arrangement of the United States, Russia, Japan, Canada, and — of course — China and the other emerging economies.

A Forecast

This highly contentious issue of a possible second commitment period for the Kyoto Protocol may come to dominate the talks in Durban. This would be unfortunate, because it would simultaneously reduce the likelihood of the negotiators making progress on a sound foundation for meaningful, long-term global action. It would probably also have the effect of producing some drama in the form of highly-charged debates, and possible threats by some delegations to walk out of the negotiations. For this reason, despite the weather, Durban may come to resemble Copenhagen more than Cancun.

The Promise and Problems of Pricing Carbon

Posted on October 30, 2011 by Robert Stavins

Friday, October 21^st was a significant day for climate change policy worldwide and for the use of market-based approaches to environmental protection, but it went largely unnoticed across the country and around the world, outside, that is, of the State of California. On that day, the California Air Resources Board voted unanimously to adopt formally the nation’s most comprehensive cap-and-trade system, intended to provide financial incentives to firms to reduce the state’s greenhouse gas (GHG) emissions, notably carbon dioxide (CO₂) emissions, to their 1990 level by the year 2020, as part of the implementation of California’s Assembly Bill 32, the Global Warming Solutions Act of 2006. Compliance will begin in 2013, eventually covering 85% of the state’s emissions.

This policy for the world’s eighth-largest economy is more ambitious than the much heralded (and much derided) Federal policy proposal – H.R. 2454, the Waxman-Markey bill – that was passed by the U.S. House of Representatives in June of 2009, and then died in the U.S. Senate the following year. With a likely multi-year hiatus on significant climate policy action in Washington now in place, California’s system – which will probably link with similar cap-and-trade systems being developed in Ontario, Quebec, and possibly British Columbia – will itself become the focal point of what may evolve to be the “North American Climate Initiative.”

The Time is Ripe for Reflection

California’s formal adoption of its CO₂ cap-and-trade system is an important milestone on the multinational path to carbon pricing policies, and signals that the time is ripe to reflect on the promise and problems of pricing carbon, which is the title of a new paper that Joe Aldy and I have written for a special issue of the Journal of Environment and Development edited by Thomas Sterner and Maria Damon on “Experience with Environmental Taxation” (“The Promise and Problems of Pricing Carbon: Theory and Experience,” October 27, 2011). [For anyone who is not familiar with my co-author, let me state for the record that Joseph Aldy is an Assistant Professor of Public Policy at the Harvard Kennedy School, having come to Cambridge, Massachusetts, from Washington, D.C., where he served, most recently, during 2009 and 2010, as Special Assistant to the President for Energy and Environment. Before that, he was a Fellow at Resources for the Future, the Washington think tank.]

Why Price Carbon?

In a modern economy, nearly all aspects of economic activity affect greenhouse gas – in particular, CO₂ – emissions. Hence, for a climate change policy to be effective, it must affect decisions regarding these diverse activities. This can be done in one of three ways: mandating that businesses and individuals change their behavior; subsidizing businesses and individuals; or pricing the greenhouse gas externality.

As economists and virtually all other policy analysts now recognize, by internalizing the externalities associated with CO₂ emissions, carbon pricing can promote cost-effective abatement, deliver powerful innovation incentives, and – for that matter – ameliorate rather than exacerbate government fiscal problems. [See the concise and compelling argument made by Yale Professor William Nordhaus in his essay, “Energy: Friend or Enemy?” in The New York Review of Books, October 27, 2011.]

By pricing CO₂ emissions (or, more likely, by pricing the carbon content of the three fossil fuels – coal, petroleum, and natural gas), governments wisely defer to private firms and individuals to find and exploit the lowest cost ways to reduce emissions and invest in the development of new technologies, processes, and ideas that could further mitigate emissions.

Can Market-Based Instruments Really Work?

Market-based instruments have been used with considerable success in other environmental domains, as well as for pricing CO₂ emissions. The U.S. sulfur dioxide (SO₂) cap-and-trade program cut U.S. power plant SO₂ emissions more than 50 percent after 1990, and resulted in compliance costs one half of what they would have been under conventional regulatory mandates.

The success of the SO₂ allowance trading program motivated the design and implementation of the European Union’s Emission Trading Scheme (EU ETS), the world’s largest cap-and-trade program, focused on cutting CO₂ emissions from power plants and large manufacturing facilities throughout Europe. The U.S. lead phase-down of gasoline in the 1980s, by reducing the lead content per gallon of fuel, served as an early, effective example of a tradable performance standard. These and other positive experiences provide motivation for considering market-based instruments as potential approaches to mitigating GHG emissions.

What Policy Instruments Can be Used for Carbon Pricing?

In our paper, Joe Aldy and I critically examine the five generic policy instruments that could conceivably be employed by regional, national, or even sub-national governments for carbon pricing: carbon taxes, cap-and-trade, emission reduction credits, clean energy standards, and fossil fuel subsidy reduction. Having written about these approaches many times in previous essays at this blog, today I will simply direct the reader to those previous posts or, better yet, to the paper we’ve written for the Journal of Environment and Development.

Although it is natural to think and talk about carbon pricing using the future tense, a few carbon pricing regimes are already in place.

Regional, National, and Sub-National Experiences with Carbon Pricing

Explicit carbon pricing policy regimes currently in place include the European Union’s Emissions Trading Scheme (EU ETS); the Regional Greenhouse Gas Initiative in the northeast United States; New Zealand’s cap-and-trade system; the Kyoto Protocol’s Clean Development Mechanism; a number of northern European carbon tax policies; British Columbia’s carbon tax; and Alberta’s tradable carbon performance standard (similar to a clean energy standard). We describe and assess all of these in our paper.

Also, the Japanese Voluntary Emissions Trading System has operated since 2006 (Japan is considering a compulsory emissions trading system), and Norway operated its own emissions trading system for several years before joining the EU ETS in 2008. Legislation to establish cap-and-trade systems is under debate in Australia (combined with a carbon tax for an initial three-year period) and in the Canadian provinces of Ontario and Quebec. And, of course, California is now committed to launching its own GHG cap-and-trade system.

International Coordination Will Be Needed

Of course, climate change is truly a global commons problem: the location of greenhouse gas emissions has no effect on the global distribution of damages. Hence, free-riding problems plague unilateral and multilateral approaches, because mitigation costs are likely to exceed direct benefits for virtually all countries. Cost-effective international policies – insuring that countries get the most environmental benefit out of their mitigation investments – will help promote participation in an international climate policy regime.

In principle, internationally-employed market-based instruments can achieve overall cost effectiveness. Three basic routes stand out. First, countries could agree to apply the same tax on carbon (harmonized domestic taxes) or adopt a uniform international tax. Second, the international policy community could establish a system of international tradable permits, – effectively a nation-state level cap-and-trade program. In its simplest form, this represents the Kyoto Protocol’s Annex B emission targets and the Article 17 trading mechanism. Third and most likely, a more decentralized system of internationally-linked domestic cap-and-trade programs could ensure internationally cost-effective emission mitigation. We examine the merits and the problems associated with each of these means of international coordination in the paper.

What Lies in the Future?

In reality, political responses in most countries to proposals for market-based approaches to climate policy have been and will continue to be largely a function of issues and factors that transcend the scope of environmental and climate policy. Because a truly meaningful climate policy – whether market-based or conventional in design – will have significant impacts on economic activity in a wide variety of sectors and in every region of a country, proposals for these policies inevitably bring forth significant opposition, particularly during difficult economic times.

In the United States, political polarization – which began some four decades ago, and accelerated during the economic downturn – has decimated what had long been the key political constituency in the Congress for environmental action, namely, the middle, including both moderate Republicans and moderate Democrats. Whereas Congressional debates about environmental and energy policy had long featured regional politics, they are now fully and simply partisan. In this political maelstrom, the failure of cap-and-trade climate policy in the U.S. Senate in 2010 was essentially collateral damage in a much larger political war.

It is possible that better economic times will reduce the pace – if not the direction – of political polarization. It is also possible that the ongoing challenge of large budgetary deficits in many countries will increase the political feasibility of new sources of revenue. When and if this happens, consumption taxes (as opposed to traditional taxes on income and investment) could receive heightened attention, and primary among these might be energy taxes, which can be significant climate policy instruments, depending upon their design.

That said, it is probably too soon to predict what the future will hold for the use of market-based policy instruments for climate change. Perhaps the two decades we have experienced of relatively high receptivity in the United States, Europe, and other parts of the world to cap-and-trade and offset mechanisms will turn out to be no more than a relatively brief departure from a long-term trend of reliance on conventional means of regulation. It is also possible, however, that the recent tarnishing of cap-and-trade in U.S. political dialogue will itself turn out to be a temporary departure from a long-term trend of increasing reliance on market-based environmental policy instruments. It is much too soon to say.

What’s Good for the Goose is Good for the Gander: Rahm’s Doctrine and Mercutio’s Complaint

Posted on September 25, 2011 by Robert Stavins

In a January 2009 article – “The Big Fix” – in the New York Times Magazine, David Leonhardt introduced a frequently-employed political strategy into popular political culture by identifying it with the new President’s Chief of Staff, Rahm Emanuel:

Two weeks after the election, Rahm Emanuel, Obama’s chief of staff, appeared before an audience of business executives and laid out an idea that Lawrence H. Summers, Obama’s top economic adviser, later described to me as Rahm’s Doctrine. “You never want a serious crisis to go to waste,” Emanuel said. “What I mean by that is that it’s an opportunity to do things you could not do before.” … That’s the crux of the doctrine.

Exploiting a Crisis

Stated less sympathetically, perhaps, the argument seems to be that sensible political strategy calls for exploiting the existence of a crisis by using it as an opportunity (excuse) to pursue policies you want, whether or not they are the best responses to the specific crisis. The crisis in this case was the worst recession since the Great Depression, and the “opportunities” on the new President’s mind were ambitious policies for health care costs and coverage, energy and climate change, and taxes.

Killing Two Birds with One Stone: Fixing the Economy and the Environment

At about the same time that Leonhardt’s article appeared in the New York Times Magazine, Elizabeth Kolbert’s profile of green jobs activist Van Jones, “Greening the Ghetto: Can a Remedy Serve for Both Global Warming and Poverty,” was published in The New Yorker. Kolbert included the following passage:

When I presented Jones’s arguments to Robert Stavins, a professor of business and government at Harvard who studies the economics of environmental regulation, he offered the following analogy: “Let’s say I want to have a dinner party. It’s important that I cook dinner, and I’d also like to take a shower before the guests arrive. You might think, Well, it would be really efficient for me to cook dinner in the shower. But it turns out that if I try that I’m not going to get very clean and it’s not going to be a very good dinner. And that is an illustration of the fact that it is not always best to try to address two challenges with what in the policy world we call a single policy instrument.”

I elaborated on that analogy and explained my concerns about the “greening of the economic stimulus package” (one element of the White House attempt “not to let a serious crisis go to waste”) in my essay on “Green Jobs” at this blog in March, 2009.

Two activities — each with a sensible purpose — can be very effective if done separately, but sometimes combining them means that one does a poor job with one, the other, or even both. In the policy world, such dual-purpose policy instruments are sometimes a good, even great idea, but other times, they are not. Whether trying to kill two birds with one stone makes sense depends upon the proximity of the birds, the weapon being used, and the accuracy of the stoner. In the real world of important policy challenges — such as environmental degradation and economic recession — these are empirical questions and need to be examined case by case.

In this case, it was (and is) important to separate the two issues: (1) environmental degradation (which in economic terms calls for pricing the externality, i.e. getting relative prices right); and (2) the economic downturn (which calls for increasing and maintaining aggregate demand in the economy). Environmental regulations address the first issue, while broad-based fiscal and/or monetary policies address the second. So, in economic terms, the imperative is to get relative prices right (internalize externalities), and avoid tilting an economic stimulus package toward any particular type of activity (such as “green jobs”).

I argued in my March, 2009 essay (and argue now) that addressing the worst economic recession in generations called for the most effective economic stimulus package that could be devised, not a stimulus package that was diminished in effectiveness through excessive bells and whistles meant to address a myriad of other (legitimate) social concerns. (And, likewise, getting serious about global climate change would require the enactment and implementation of meaningful, dedicated climate policies.)

By the way, I do not wish to add any fuel to the current political fire raging over the bankruptcy of Solyndra, the solar power manufacturer supported by a $500 million Federal loan guarantee under the stimulus package. The failure of Solyndra was largely due to the collapse of silicon prices and the consequent increased competitiveness of conventional solar cell technologies. I will leave it to others to debate whether the government should have seen this coming.

My point rather is that there is a strong counterargument to Rahm’s Doctrine, and that counterargument is – in the words again of David Leonhardt – “hardly trivial — namely, that the financial crisis is so serious that the administration shouldn’t distract itself with other matters. That is a risk, as is the additional piling on of debt for investments that might not bear fruit for a long while.”

That’s the Goose – What About the Gander?

Do not think for a moment that only Democrats are quick to subscribe to and employ Rahm’s Doctrine. On the contrary, Republicans – particularly the ultra-conservative ones that are coming to dominate the Party – have recently embraced it with breathtaking enthusiasm by exploiting national concerns about the sluggish economy and stubbornly high levels of unemployment in order to pursue their anti-regulatory agenda and focused attack on the U.S. Environmental Protection Agency.

As I have also written at this blog (“Good News from the Regulatory Front,” April 25, 2011), the blanket characterization of environmental regulations as “job killers” is simply inconsistent with decades of economic research. In the short term, new environmental regulations can have either positive or negative effects on employment in particular sectors, but in the long term, their employment impacts are trivial when compared with those of the overall set of factors that affect national employment levels. Attacking EPA “to save jobs” is a shameful attempt to exploit economic fears in pursuit of an ideological agenda (whether or not that agenda has social merit).

Enter Mercutio

So, as is so often the case, this economist (like many – maybe most – others) disagrees with the economic arguments put forward by both sides in the political world. Talking about “job-killing environmental regulations” is dishonest, and no more than another cynical application of Rahm’s Doctrine. But the same must be said about the “greening of the stimulus,” and the ongoing, bloated claims about “clean energy jobs.” As usual, those of us in the moderate middle are left to echo Mercutio’s censure: “A plague o’ both your houses!”

The Credit Downgrade and the Congress: Why Polarized Politics Paralyze Public Policy

Posted on August 11, 2011 by Robert Stavins

There’s room for debate about whether U.S. government deficits justify Standard & Poor’s downgrading last week of long-term U.S. debt, but the more important factor cited in S&P’s report is that “the effectiveness, stability, and predictability of American policymaking and political institutions have weakened…” The S&P team emphasizes that “the difficulties in bridging the gulf between the political parties … makes us pessimistic about the capacity of Congress and the Administration” to address the crucial problems the country faces.

Although these S&P judgments were intended to refer exclusively to fiscal policy, they really apply to a much broader set of issues, ranging from economic to health to environmental policies. The key reality is this: there is a widening gulf between the two political parties that is paralyzing sensible policy action.

Political Polarization

This increasing polarization between the political parties has shown up in a number of studies by political scientists employing a diverse set of measures that place roll-call votes by members of Congress on an ideological spectrum from extreme right to extreme left. This polarization – the disappearance of moderates – has been taking place for four decades. The rise of the Tea Party movement within the Republican Party is only the most recent vehicle that has continued a 40-year trend.

Why has this collapse of the middle taken place; why has party polarization increased so dramatically in the Congress over the past 40 years? In my view, three structural factors stand out.

Three Structural Factors

First, there has been the increasing importance of the primary system, a consequence of the “democratization” of the nomination process that took flight in the 1970s. A small share of the electorate vote in primaries, namely those with the strongest political preferences – the most conservative Republicans and the most liberal Democrats. This self-selection greatly favors candidates from the extremes.

Second, decades of redistricting – a state prerogative guaranteed by the Constitution – has produced more and more districts that are dominated by either Republican or Democratic voters. This increases the importance of primary elections, which is where the key choices among candidates are now made in many Congressional districts. Because of this, polarization has proceeded at a much more rapid pace in the House than in the Senate.

Third, the increasing cost of electoral campaigns greatly favors incumbents (with the ratio of average incumbent-to-challenger financing now exceeding 10-to-1). This tends to make districts relatively safe for the party that controls the seat, thereby increasing the importance of primaries.

These three factors operate mainly through the replacement of members of Congress (whether due to death, retirement, or challenges from within the party) – that is, the ideological shifts that cause increasing polarization largely occur when new members are elected (from either party, although a disproportionate share of polarization has been due to the rightward shift of new Republicans).

To a lesser degree, polarization has also taken place through the adaptation of sitting members of Congress as they behave more ideologically once in office. Such political conversions are due to the same pressures noted above: in order to discourage or survive primary challenges, Republican members shift rightward and Democratic members shift leftward.

A recent case in point is Senator John McCain, Republican of Arizona, who evolved from being a moderate at the time of his 2008 Presidential run to being a solid conservative in 2010, in response to a primary challenge from a Tea Party candidate.

Long-Term Implications

If the increasing polarization of the Congress is due to these factors, then it is difficult to be very optimistic about the prognosis in the near term for American politics. This is because it is unlikely that any of these factors will soon reverse course.

The two parties are not about to abandon the primary system to return to smoke‑filled back rooms. Likewise, no state legislature is willing to abandon its power to redistrict. And public financing of campaigns and other measures that would reduce the advantages of incumbency remain generally unpopular (among incumbents, who would – after all – need to vote for such reforms).

Other Factors?

True enough, in addition to these long-term structural factors that have driven political polarization, shorter-term economic and social fluctuations have also had pronounced effects. In particular, significant economic downturns – whether the Great Depression of the 1930s or the Great Recession of the past several years – increase political polarization.

The 1930s saw not only the rise of American socialists and communists, but also the rise of American right-wing extremism. It took World War II to bring an end both to the economic upheaval of the 1930s and the destructive political polarization that had accompanied it.

U.S. participation in the war brought a degree of political unity at home, largely because U.S. action was precipitated by the attack on Pearl Harbor. Under conditions of less clear motivation for U.S. military action abroad – such as the war in Vietnam – the result has not been political unity, but divisiveness and polarization. The ultimate impacts on domestic politics of the wars in Afghanistan and Iraq may hinge on whether they are perceived to be patriotic responses to a foreign attack (9/11) or the latest manifestations of U.S. military adventurism.

The Future

So, it’s reasonable to anticipate – or at least to hope – that better economic times will reduce the pace of ongoing political polarization. However, in the face of the three long-term structural factors I’ve identified above – the increasing importance of primaries, continuing redistricting, and the increasing costs of electoral campaigns – it is difficult to be optimistic about the long-term prognosis for American politics.

No matter how one feels about the wisdom of Standard & Poor’s downgrading of long-term U.S. debt, the issue of greater concern should be their assessment of the state of the U.S. body politic.
