This grant to the National Bureau of Economic Research (NBER) supports a predoctoral fellowship program that will support Ph.D. students carrying out research in behavioral macroeconomics. Four dissertation fellowships will be awarded to promising graduate students for a period of two years each. Potential dissertation topics include the aggregate implications of limited information, decision-making with flawed models, how expectations are formed, optimal policy design, and the interaction of economic agents with different levels of knowledge or economic sophistication. In addition to the fellowships, grant funds will support an NBER initiative to expand the community of behavioral economists by holding one-week boot camps each year that will train two dozen young scholars in topics in behavioral macroeconomics.
