Magne Mogstad is the Gary S. Becker Professor in Economics and the College in the Kenneth C. Griffin Department of Economics at the University of Chicago, as well as the Director of the Ronzetti Initiative for the Study of Labor Markets at the Becker Friedman Institute at the University of Chicago. His work is motivated by the broad question of how to address market failures and equalize opportunities. Countless policies – taxation, subsidized education, social insurance – have been implemented in an effort to achieve those objectives. A key challenge is to distill each policy's unique impact so that we can understand which ones actually work and which ones do not. This challenge motivates Magne's work, which aims at providing credible empirical evidence that informs policymakers. This is made possible by combining theory and econometric methods with large administrative datasets that can be linked to supplementary data sources. Magne has published extensively in leading scholarly journals. He is a current co-editor of the Journal of Political Economy, and he previously served as a co-editor of the Journal of Public Economics and a foreign editor of the Review of Economic Studies. He is a recipient of the Alfred P. Sloan Foundation Fellowship and the 2017 IZA Young Labor Economist Award.
