2026-11-12 10:00:00 2026-11-12 11:00:00 America/New_York Health Policy Research Seminar: Jisung Park, PhD, MSc "Local Labor Market Conditions and Adaptation to Climate Change: The Role of Workers' Outside Options." Extreme heat is a growing occupational health hazard, yet little is known about what determines whether workplaces adapt to it. Using administrative data on 15 million workers' compensation injury claims and measures of workers' outside options in more than 17,000 local occupational labor markets, this talk shows that a day above 90°F raises workplace injuries by 9 percent, and that plausibly exogenous improvements in workers' outside option wages substantially reduce this effect: a one standard deviation increase in outside option wages lowers the heat-injury relationship by 46 to 64 percent, including in many indoor settings. The findings suggest that local labor market conditions shape how well workers are protected from environmental health risks, and who bears the costs of adaptation. Dr. R. Jisung Park is an environmental and labor economist interested broadly in how environmental factors shape economic opportunity. Prior to joining Penn, he was a member of the faculty at UCLA, and a post-doctoral fellow at Harvard. Dr. Park’s research combines data, quasi-experimental methods, and economic analysis to better understand the implications of environmental change for human flourishing, and how effective policy responses may be designed. For instance, his work on heat and learning uses data from millions of test scores to understand how the physical environment in which learning occurs may affect educational achievement gaps, how climate change may influence economic inequality, and what this might imply for public policy regarding climate mitigation and adaptation. Ongoing work examines such topics as the effects of extreme heat on workers and labor market inequality, the consequences of natural disasters for human capital, and the process by which workers and firms adapt to a changing environment. Dr. Park received a PhD in economics from Harvard University, where he was an NSF Fellow, and master’s degrees in Environmental Change and Management (MSc) and Development Economics (MSc) from the University of Oxford, where he was a Rhodes Scholar. His work has been published in the American Economic Journal: Economic Policy, the Journal of Human Resources, Nature Human Behavior, Nature Energy, and the Review of Environmental Economics and Policy, and is widely cited in such media outlets as the New York Times, the Wall Street Journal, Bloomberg, the Washington Post, the BBC, the Guardian, the Financial Times, and NPR. Dr. Park has also advised policymakers and practitioners including in the form of Congressional Testimony for the U.S. House of Representatives, and briefings for the United Nations, the World Bank, the U.S. Department of Commerce, the U.S. Environmental Protection Agency, the U.S. Department of Labor, the California State Legislature, the United Kingdom Department for International Development, United Technologies, UBS, and the Bill and Melinda Gates Foundation.
