Studying the Real Impacts of Climate Change Policies

Over the past three years, in my podcast series, “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program,” I’ve held conversations with many long-time leaders in the world of environmental economics and policy.  But that has meant, quite naturally, that I have most frequently engaged with people – like me – in the grey-haired set.  So, I was particularly pleased to welcome to my most recent podcast someone who is decidedly younger than most of the people I’ve previously interviewed, but who – I hasten to add – is nevertheless a highly accomplished scholar, a full professor at the University of California, Berkeley, and continues to carry out important research.  I’m referring to Meredith Fowlie, Professor of Agricultural and Resource Economics and Co-Director of the Energy Institute at Haas, at U.C. Berkeley.  In addition, Meredith is a Research Associate at the National Bureau of Economic Research.  The podcast is produced by the Harvard Environmental Economics Program.  You can listen to our complete conversation here.

Fowlie has worked extensively on the economics of energy markets and the environment, with investigations of the real-world applications of market-based environmental regulations, the economics of energy efficiency, the demand-side of energy markets, and energy use in emerging economies. Her work has appeared in the American Economic Review, the Journal of Political Economy, Quarterly Journal of Economics, the Review of Economics and Statistics, and other leading academic periodicals.

She received her B.Sc. degree in International Agriculture and Development from Cornell University in 1997, an M.Sc. in Environmental Economics from Cornell in 2000, and her PhD in Agricultural and Resource Economics from U.C. Berkeley in 2006.  Before joining the faculty at U.C. Berkeley, she was an Assistant Professor of Economics and Public Policy at the University of Michigan.

Meredith is well known for her research on how environmental regulations have worked in practice.  One prominent example is her 2018 QJE paper co-authored with Michael Greenstone and Catherine Wolfram (both previous podcast guests), “Do Energy Efficiency Investments Deliver?: Evidence from the Weatherization Assistance Program,” which examined the efficacy of the federal Weatherization Assistance Program, which works with local energy services providers installing energy efficiency measures.  The research was both important and controversial.

“What we found was that the energy savings were less than half of what engineering projections had anticipated. So, that was a disappointing finding. It just meant that we weren’t getting the savings that the models projected and that the program wasn’t delivering as hoped,” Fowlie remarks. The reason the paper was controversial, she notes, is that the findings did not align with what lawmakers had expected.

Fowlie celebrates the work of her research assistant on that project, Erica Myers, who demonstrated in subsequent research how some relatively simple weatherization program adjustments could have significant upsides.

“[In her research, Myers found] that if you incentivize the workers who are making these improvements on the home, such that their compensation depends partly on the performance, you can significantly increase the effectiveness of those investments. And she has also been able to identify those investments that perform the best in order to help target some of these weatherization investments,” Meredith notes.

As I noted above, the impacts of such government regulation have been the focus of much of Fowlie’s research. In the podcast, she emphasizes that market outcomes often deviate from what is anticipated, because of the unexpected impacts of economic incentives, something policymakers need to pay close attention to when seeking and designing policy solutions to climate change.

“When we think about the industries that are on the front lines of climate change – that’s electricity; it’s natural gas; it’s insurance – a lot of these sectors and firms are subject to [previous] economic regulation. Regulators determine what investments get made, how costs get recovered, what prices get set. And I’m increasingly seeing that less as a bug and more as a feature. We have these economic regulatory tools at our disposal, and if we start thinking about them like climate policy tools, we can actually get a fair bit of leverage out of those tools,” she says. “I’m thinking about how public utility commissions set electricity rates in particular, and thinking about how those regulatory decisions have pretty profound implications for how we mitigate climate change and who pays the price.”

I also asked Meredith Fowlie for her thoughts on the topics of “environmental justice” and “just transition.”

“I’ve been thinking about these elevated concerns in a number of respects. One is, who is paying for climate mitigation and adaptation? These are needed investments, but how we make these investments has some implications for who ends up paying, and sometimes that’s unintentional,” she notes. “Part of my research is thinking about how we’re paying for climate mitigation and adaptation, and who ends up paying the cost. A second concern is cap-and-trade programs and the environmental justice concerns about those programs, particularly in California, and program design changes we could consider making in light of those concerns.”

At the end of our conversation, when we turn to the current youth movements of climate activism, Meredith expresses her admiration for the ways in which they are focusing attention on important issues.

“There’s a sense of urgency among the students I teach that I think is important and I want to encourage.  I have learned a lot talking to them about their concerns and their impatience and their frustration. And I hope they’ve also learned from me about some of my concerns with how they want to move forward and what approaches they want to take,” she stated. “There’s certainly a youthful energy in terms of the level of commitment they’re bringing, but I think it’s going to change the trajectory of many, many youth who are going to have a really profound impact on how we tackle the [climate change] problem in future generations.”

The Challenge Posed to U.S. Climate Policy by Political Polarization

In my podcast series, “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program,” I’ve enjoyed chatting with economists who have been leaders in the realm of environmental, energy, and resource economics.  My most recent guest fits in that group, because I was joined by Kathleen Segerson, who in addition to her academic and scholarly research and teaching, has served on numerous state, national, and international advisory boards.  The podcast is produced by the Harvard Environmental Economics Program.  You can listen to our complete conversation here.

Segerson, the Board of Trustees Distinguished Professor of Economics at the University of Connecticut, is a Member of the National Academy of Sciences and a Fellow of the Association of Environmental and Resource Economists, the Agricultural and Applied Economics Association, and the Bayer Institute of Ecological Economics in Stockholm. Her advisory roles have included time spent as a Member of the U.S. Environmental Protection Agency’s Science Advisory Board (SAB), where she had a close-up view of Washington political battles over environmental issues, including climate change policy. She acknowledges that the politics have only gotten worse.

“I think that it is really quite concerning how polarized we are now in this country, at least, on some of these issues,” Segerson remarks. “Some approaches, or at least concerns that might have been bipartisan in the past have become quite polarized now and that makes it very difficult to think about policy and how to move forward.”

Segerson says that many of the policy tools currently used to address climate change in the United States are less than ideal.

“One of the things that we’ve done, of course, recently is to enact the Inflation Reduction Act, which includes a lot of climate measures. Many of those are subsidy based. And as you know, economists wouldn’t typically be looking to subsidies as the ideal policy instrument to use to try to foster transformational change,” she states. “That, I think is a concern because it sets a precedent for policy. It obviously has large budgetary implications. We’ll see whether those subsidies can be effectively phased out if and when [they are] no longer needed. Let’s hope they’re no longer needed at some point, that they’ve been sufficiently successful, that they aren’t needed in the future.”

Segerson also addresses the issue of environmental justice and the Justice40 Initiative, which seeks to ensure that a certain level of investment is targeted for disadvantaged communities that have historically been underserved or highly affected by pollution.

“The challenge is identifying those communities. Which communities should be considered eligible for helping to meet the Justice40 goals? How do you define that? How do you measure it? Of course, the challenges are very different across different communities. So, how do you compare [and] calculate cumulative burdens?,” she asks. “There are a lot of … challenges associated with implementing policies to try to address the environmental justice concerns that are out there, and obviously very legitimate and need to be addressed.”

Segerson also expresses her optimism about the increase of youth movements of climate activism in recent years, saying that while she may question some of the tactics, she supports the objective of focusing attention on important climate policy issues.

“We need the young generation to be the ones who are, in some sense, drawing increased attention because the older generations, at least some parts of them, are not stepping up to that challenge,” she states. “I know that the people who are young parents … or teenagers or college students now, it’s really about their future and their right to feel indignant that those of us who are much older are not doing what we can or should be doing to try to ensure that future.

“I think at this point, they’re sufficiently young that they can try to demand it, but actually putting it in place is more challenging. Let’s hope that they can translate that activism or that it does translate into some real change at some point.”

An Expression of Hope and Frustration re Climate Change Progress

In our podcast series, “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program,” I’ve had the pleasure of engaging in conversations over the past three years with a significant number of truly outstanding economists who have carried out important work in the realm of environmental, energy, and resource economics.  My most recent guest is no exception, because I am joined by Geoffrey Heal, the Donald Waite III Professor of Social Enterprise at Columbia Business School, where he previously served as Senior Vice Dean, essentially the chief academic officer of the School.

More to the point, Geoff Heal is the author of 18 book and some 200 articles, a Fellow of the Econometric Society and the Association of Environmental and Resource Economists, where he served as President.  And Geoff has also held – and continues to hold – important advisory and other positions with governmental, multi-governmental, and non-governmental organizations.  I hope you will listen to our complete conversation here.

Among his writings is the pathbreaking 1979 book “Economic Theory and Exhaustible Resources,” co-authored with Partha Dasgupta, which is widely viewed as a seminal work in the field of resource and environmental economics.  I asked Geoff how the book came about.

“Partha and I enjoyed collaborating, and I think it’s something that we just felt sort of intellectually compelled to write because we felt the time was right and we felt that we could make a contribution … particularly acting together,” Heal remarks. “But I don’t think we had any sense of the impact it would have, quite frankly.  And I find students still reading it today, which is quite remarkable.”

Heal also addresses the question of how much the field of resource and environmental economics has changed during his time in academia over the past 40 years.

“The field has been transformed, hasn’t it? I mean, in the last decade or so, it’s been transformed into a much more empirical field than it was before that. What they call the ‘credibility revolution’ in economics has taken hold in environmental and resource economics,” he said. “We’ve got a vast number of papers using interesting novel data sets to look at climate impacts or regulatory impacts, and I think they’ve increased our understanding of the impact of environmental issues and environmental policies… considerably.”

Serving as a Coordinating Lead Author in Working Group III of the Intergovernmental Panel on Climate Change’s (IPCC) Fifth Assessment Report, which was finalized in 2014, Heal had a front row seat in the analysis of climate change policy. That said, he admits he is a bit frustrated with the pace of collective efforts to reduce greenhouse gas emissions and combat the effects of global climate change.

“I think that we know a lot about how to solve the climate problem. I think the technologies that we need to solve it are largely, perhaps not totally, but largely available… So, I think we know how to move to an electric grid which is powered entirely without fossil fuels,” he states. “We have a lot of the pieces available. We’re not just deploying them fast enough to reach the targets that we think we need to reach …so I find that frustrating. We’re very close to being able to achieve the goal, but we’re not actually doing what we need to do.”

When I ask Geoff Heal why current climate policies don’t seem to be accomplishing their goals, he cites politics.

“It’s the enormous influence of the fossil fuel industry and the sense of mostly some conservatives that this is a plot to increase the powers of the state. And of course, the Ukraine war has really been a major problem too, because it’s caused Europeans to move away from natural gas and in some cases back to coal, which is a terrible piece of backsliding, and it’s understandable under the circumstances, but it’s very regrettable from the climate perspective,” he says. “The Ukraine war, I hope, is a temporary phenomenon, whereas the power of the fossil fuel industry and the sort of conservative misapprehensions about what climate change is all about, I think are more real and more enduring.”
