A Rising Star Shares His Thoughts on Land Use & Climate Policy

In my podcast series, “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program,” I’ve had the pleasure of engaging in conversations with a significant number of outstanding economists, who have carried out important work relevant for environmental, energy, and resource policy, including by serving in important government positions.  That inevitably brings with it the reality that many of the people I’ve spoken with have been senior leaders in the profession, with the emphasis on the word “senior.”  I’m very pleased to say that in my most recent podcast, I’ve broken that mold with someone who is a young, rising star in the world of environmental economics, particularly in the realm of analyzing the causes and consequences of changes in land use.  I’m referring to my colleague, Charles Taylor, a relatively new Assistant Professor of Public Policy at the Harvard Kennedy School.  You can listen to our complete conversation here.

Taylor’s research often uses satellite data to address policy questions associated with land use, and at the beginning of our conversation, he explains that he first got interested in land use issues during his time spent as a consultant at McKinsey & Company, following his undergraduate years at the University of Virginia.

“I got to go work abroad in Qatar, Brazil, and Europe, and get a lot of exposure to these big climate change and land-based initiatives that governments and the private sector were doing. And I got really excited by that, and also very quickly learned I didn’t want to be a consultant,” he says. “I felt that I wanted to get more either skin in the game at that time or more in depth into the issues, and that prompted my journey into more of the entrepreneurial world.”

Charles soon connected with David Tepper, a former banker who shared his passion for land use issues, and together they co-founded Earth Partners, a private company that provides land restoration and bio-energy services intended to help rebuild soils, habitats, and other critical ecosystems.

“How do we restore ecosystems to meet all the challenges we’re facing, from water to food security to pollution to climate change, and how do we do that at scale?  [The idea was to] start a company [dedicated to] next generation land management,” he remarks. “A lot of the challenges we’re facing as a society directly or relate to land management, and looking around, I didn’t really see any companies or organizations taking that head on.”

Charles notes that he decided to pivot from his entrepreneurial venture into academia once he realized the limits of what can be accomplished with capital alone.

“We had great small-scale investors who wanted to do good things, but you still had to get their money back in a few years and that limits the scope of what you can do if you really want transformational change,” he explains. “So, that made me say, okay, what if I went back to the research side and found some way I could contribute to these problems on the other side while keeping one foot or at least half my brain in this world of how this … on the ground world works?”

Much of Charles Taylor’s current academic research relates directly to environmental economics associated with land use decisions, and is intended to inform lawmakers and other stakeholders of the benefits of specific policy choices.

“Humans have touched nearly every acre of non-barren land on earth. We’ve transformed it. We farm it for our food. We take its water. We shape its rivers for reservoirs, for irrigation. We use the wood for forests. We build on it for housing… We get our energy out of it, increasingly for renewable energy. We need a lot of it for siting wind and solar. And then climate change interacts with all this,” he says. “So, there’s all these questions I am really curious about [and am interested in] quantifying and using some of the empirical tools we have [to do that].”

Taylor references a recent paper he co-authored with Caltech Assistant Professor Hannah Druckenmiller that examines land use regulation under the Clean Water Act.

“You might see this spurious relationship between where wetlands are lost and more flood damages, for example, to think of one of the benefits of wetlands. And that paper was just trying to find an empirical way to uncover that and give an estimate of the value of wetlands that then could be used by the EPA in measuring the cost and benefits of these types of regulations, which are super important and cover almost all land use decisions and where you’re going to build in the U.S.,” he explains.

A Behavioral Economist Thinks About Energy and Climate Change

When examining environmental, energy, and climate change policy, the methods and the topic of behavioral economics arise with some regularity.  In my podcast series, “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program,” we’ve talked about such behavioral research in regard to energy-efficiency policies with Michael Greenstone and others.  And, much more recently, in a podcast episode just released, I had the opportunity to talk with a behavioral economist who is now on the faculty of a school that’s focused on environmental studies.  I’m referring to Hunt Allcott, who is Professor of Global Environmental Policy at the Doerr School of Sustainability at Stanford University, and who – I’m proud to say – is a graduate of the PhD program in Public Policy at Harvard.  You can listen to our podcast conversation, produced by the Harvard Environmental Economics Program, here.

Allcott serves as Co-Director of the Stanford Environmental and Energy Policy Analysis Center, and is a Research Associate at the National Bureau of Economic Research, as well a member of the board of editors of the American Economic Journal: Economic Policy.

The crux of Allcott’s research focuses on the ways in which human behavior affects economic decisions and outcomes in a variety of contexts, and the lessons those have for policymaking. In our conversation, he cites several examples where government policy can influence consumer decisions in ways that will benefit both consumers and the environment.

“It’s like what behavioral economists call a shrouded attribute. It’s a future cost that’s kind of easy to forget when you’re making a purchase decision. So, if it’s… true that consumers aren’t thinking very hard about these future energy costs, then we’re probably erring on the side of buying too many gas guzzling cars and energy guzzling air conditioners and light bulbs. And so, as a result, the government can make us better off by pushing us in the direction of being more energy efficient,” Allcott remarked. “It was fun for me to… work with a group of others to develop actual empirical tests of, okay, how would you substantiate those consumer protection arguments in the data? So, that’s some of the work that I’m most proud of.”

Allcott also discusses the federal electric vehicle tax credits, which are designed to incentivize consumers to reduce carbon emissions.

“You subsidize a new electric vehicle, that’s a new EV on the road, [and] that’s good for the environment in most places. You give somebody a tax credit to buy a used EV, that’s just trading an electric vehicle from one person to another, and so there’s no new net vehicle on the road, at least [not] directly,” he stated. “Is the incidence really on the used vehicle buyer, in which case there’s no environmental benefit, or maybe the prices of used electric vehicles are going up because they’re worth more upon resale. That’s not as good for the buyers, but then it might induce more new electric vehicle sales because when you buy a new EV, you then recognize that the resale value might be higher.”

Allcott officially joined the faculty at the Doerr School in September 2022, just as the school was being launched.

“There are 60 existing faculty members that were moved into that school as part of earth systems, energy systems, civil engineering, and some other departments. I was actually… the first external hire of this school to reach through the provost and actually show up on campus. And so, I’ve been here for, I guess, 15, 16 months so far, and it’s just been a great experience trying to help Stanford have an even bigger imprint in this space of impact on energy and environmental issues.”

Ironically, Allcott notes that much of the research taking place at the Doerr School and in which he’s now engaged is not focused on behavioral economics.

“This has been an opportunity to step back and rethink what is the right research direction for the next five to ten years. And perhaps interestingly, all the topics that our group is now working on are what I would call non-behavioral topics. There’s not really a behavioral economics angle to them,” he explained. “Upon arriving at Stanford [I asked] ‘okay, I’m in the sustainability school. What are the most important environmental economics topics?’ I think energy efficiency and behavioral economics is still on that list, but there’s so much other stuff. There’s the Inflation Reduction Act, there is electricity market design, and then within each one of those two, there’s a lot of different sub-areas that we’re actually focusing on.”

An Eminent Economist Talks About Climate Change

In my 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 four years with a significant number of truly outstanding economists who have carried out important work in the realm of environmental, energy, and resource economics, and have been real leaders in the profession.  In my most recent podcast, we topped that, because I was joined by someone who has made important contributions not just in the realm of environmental and resource economics, but has been a global leader in the discipline of economics broadly, across numerous sub-fields, and has ventured and published well beyond economics in seemingly disparate realms, ranging from contract bridge to Italian Rennaisance painting.  All in all, he is the author or editor of 14 books and more than 300 scholarly articles. 

I am, of course, referring to my Harvard colleague – and good friend – Richard Zeckhauser, the Frank Ramsey Professor of Political Economy at the Harvard Kennedy School, and Distinguished Fellow of the American Economic Association, the Econometric Society, the American Academy of Arts and Sciences, the Association of Public Policy and Management, and the Society for Benefit-Cost Analysis.  Beyond that, I want to acknowledge that he is celebrated at Harvard and beyond as a marvelous classroom teacher, and a valued mentor to generations of students and faculty colleagues.

Near the beginning of our conversation, Richard laments a phenomenon he terms “the pumped equilibrium,” in which people hold exaggerated expectations about confronting the challenge of climate change if we do not drastically increase our efforts.  

“People started at least three decades ago saying, ‘Climate change is a terrible problem, but we can control it by cutting back on our greenhouse gases, and this is the last decade that we can do that. If we don’t do it this decade, we’re dead.’ And then, the next decade they said … the same thing. And this decade they’re saying … the same thing. And they keep telling us that we’re going to be able to [limit the global temperature increase to] two degrees centigrade above pre-industrial levels, or even more recently, 1.5 degrees centigrade above pre-industrial levels. I think that’s unrealistic.”

Richard maintains that instead a realistic assessment of the current state of climate change requires new approaches to make an impact.

“The United States has done a so-so job of cutting our emissions by about 10 percent over a number of years, but at the same time, China has increased its emissions by 13 percent, and you can expect that countries like India will be growing much faster in its emissions [levels],” he remarks. “So, I think that we should take a sober look at these problems and say, ‘What else can we do?’”

Climate adaptation, Zeckhauser states, holds the potential for greatly reducing the impacts of climate change. He cites one example in which scientists have proposed building a 100-foot-tall berm around a fjord in Greenland where warm water currently flows in and melts the ice sheets.

“This is very speculative. Will this work? I sure hope so. It’s within our realm of technological capability, but I think we should be looking for many solutions like this that could enable us to deal with … what I consider to be [the] catastrophic track that we’re on,” he says. Other potentially effective adaptation measures, he states, include increasing the alkalinity of the oceans and enforcing smarter logging policies to protect mature trees.

When I question Richard about the distributional implications of climate change, he remarks, “I think dealing with climate change and reducing its impact will automatically have very beneficial distributional consequences.  The places that are currently suffering the most from climate change are the hottest places in the world, which are both suffering under [rising] temperatures and having their weather patterns shifted. So, you would be doing God’s work in restoring or preserving the planet, and you’d be doing work that’s to the benefit of the most affected people in the world.”

He also refers in this context to the challenges posed by massive migrations of people who want to escape rising temperatures in the south by heading north.

“Those [migration patterns] are very uncomfortable for the people in both places – the people who have to do the migration, which is frequently very dangerous and expensive, the people who are still trapped in the old place because they don’t have enough resources, and the people whose areas are being affected by the new people who are coming.”

Zeckhauser says that ultimately, it is up to policymakers around the world to confront the climate change challenge.

“This is a political problem on a global scale. So, even if you didn’t want to worry about it, as a political actor, as the president of the United States has to be and our climate envoy has to be, and the UN has to be, you have to pay serious attention to it.”

My conversation with Richard Zeckhauser is the first episode of 2024 and the 57th episode over the past four years of the Environmental Insights series, with future episodes scheduled to drop each month.  You can find a transcript of our conversation at the website of the Harvard Environmental Economics Program.  Previous episodes have featured conversations with:
