Ellen McGrattan is a consultant at the Federal Reserve Bank of Minneapolis, a professor of economics at the University of Minnesota, and director of the Heller-Hurwicz Economics Institute. She is also a research associate at the National Bureau of Economic Research, a Fellow of the Econometric Society, a Fellow of the Society for the Advancement of Economic Theory, a member of the Bureau of Economic Analysis Advisory Committee, a member of the Minnesota Population Center Advisory Board, and President-elect of the Midwest Economics Association. Ellen received her B.S. in economics and mathematics from Boston College and her Ph.D. from Stanford University. Prior to coming to Minnesota she taught at Duke University. She has also taught short courses at European University Institute, University of Pennsylvania, Stockholm School of Economics, UCLA, International Monetary Fund, Arizona State University, and Universidad do Minho. Ellen’s research is concerned with the aggregate effects of monetary and fiscal policy—in particular, the effects on GDP, investment, the allocation of hours, the stock market, and international capital flows. Her recent work reexamines some business cycle puzzles in macroeconomics, considering the fact that some investments are unmeasured. Along with colleague Ed Prescott, she has also been analyzing policy reforms related to financing retirement in economies with aging populations.
