报告人简介

Roger H. von Haefen is a Professor and Associate Department Head in the Department of Agricultural and Resource Economics and Associate Director of the Center for Environmental and Resource Economics Policy at North Carolina State University. He is also the current Co-Editor-In-Chief of the Journal of Environmental Economics and Management and lead organizer of Camp Resources, a workshop dedicated to training the next generation of environmental and resource economists. His research spans nonmarket valuation, transport, economic measurement, and applied econometrics. Through funding from several government agencies and foundations, he has assessed the economic damages associated with the 2010 Deepwater Horizon oil spill, the impacts of climate change on outdoor recreation, the economic benefits of water quality improvements in lakes and streams in the Southeastern U.S., and the distributional and efficiency effects of higher gasoline taxes on the U.S. economy.  Dr. von Haefen has supervised over a dozen doctoral dissertations and published in leading general-interest and environmental field journals. He holds a Bachelor of Arts from the University of Notre Dame and a doctorate from Duke University, both in economics.

Over the past two decades, coastal areas in the United States have experienced significant improvements in air quality, driven by stricter federal PM2.5 standards and cleaner fuel requirements for maritime shipping. However, the impact of these improvements on outdoor recreation, a major and growing sector of many coastal economies, remains unclear. Our study examines how changes in air pollution along the East and Gulf Coasts affected shoreline recreational fishing from 2004 to 2018, using one of the largest outdoor recreation datasets ever assembled. Through a linked model of angler participation and site choice, we found a strong negative and statistically significant relationship between PM2.5 levels and shoreline recreational fishing. This relationship suggests substantial welfare gains from recent air quality improvements. Our results also show significant regional variations across the U.S., with anglers in the Southeast and New England/Mid-Atlantic regions benefiting the most economically. Sensitivity analyses confirm that our baseline estimates remain robust when accounting for factors such as changes in local recreation patterns, income effects, nonlinear air pollution effects, heat effects, and alternative distributional assumptions.
