Erzo F.P. Luttmer holds the Dartmouth Professorship in Economics at Dartmouth College. He serves as the editor of the American Economic Review. His research seeks to understand what drives the demand for redistribution and social insurance, and how the implementation of redistribution and social insurance programs can be improved. Many of his papers highlight the important role of social effects in economic behavior. Much of his more recent research explores the role of cognitive limitations on demand for and design of social insurance programs.
