Swarthmore College Men’s Basketball alumnus Michael Greenstone, class of 1991, appeared on this week’s episode of Then & Now to discuss his time at Swarthmore and his career in economics with host Brandon Hodnett. Greenstone was a 1,000-point scorer for Swarthmore Men’s Basketball and earned his bachelor’s with high honors in economics. He earned his PhD in economics from Princeton and is now the Milton Friedman Distinguished Service Professor in Economics, the College, and the Harris School, as well as the Director of the Becker Friedman Institute and the interdisciplinary Energy Policy Institute at the University of Chicago. Greenstone previously served as the Chief Economist for President Obama’s Council of Economic Advisers, where he co-led the development of the United States government’s social cost of carbon. His research has influenced policy globally and focuses largely on uncovering the benefits and costs of environmental quality and society’s energy choices. In this episode, he recounted scoring his 1,000th point while being guarded by his brother, how Swarthmore encouraged his intellectual curiosity, how his Air Quality Life Index has helped visualize pollution’s impact on life expectancy, and how he’s currently studying COVID testing.
