I am an associate professor at the University of Pennsylvania School of Social Policy & Practice, and a Faculty Research Fellow at the National Bureau of Economic Research. I study the labor market to craft policies that can enhance employment, productivity, and economic security. To make an informed policy decision, it is crucial to determine the costs and benefits of policies. My research expertise includes wage determination and monopsony power, antitrust law for the labor market, the universal basic income, unemployment insurance, the minimum wage, and employment contracts. My research has been published in leading academic journals such as the Quarterly Journal of Economics, the Journal of Labor Economics, the American Economic Journal: Macroeconomics, and the Journal of Public Economics. I testified for policy makers, including Congress and the Federal Trade Commission. My research has been cited in many media outlets including the New York Times, CNN, and the Wall Street Journal.
