J. Bradford DeLong is professor of economics at the University of California at Berkeley, where he has been teaching since 1995. Before starting to teach at Berkeley, he was deputy assistant secretary for economic policy in the United States Department of the Treasury (1993 to 1995), where an enormous range of issues crossed his desk — from what the Federal Reserve will do next week to whether the Uruguay Round of the GATT should be ratified to the macroeconomic implications of the (unsuccessful) health care reform. Before working at the Treasury he was an associate professor at Harvard University, where he was both an undergraduate student (B.A. 1982) and a graduate student (Ph.D. 1987). He has also taught at Boston University and MIT.
     Professor DeLong is also a research associate of the National Bureau of Economic Research and a visiting scholar at the Federal Reserve Bank of San Francisco. And he is a former coeditor of the Journal of Economic Perspectives.
     Professor DeLong’s research interests range from the origins of the Great Depression to the effect of irrational speculation on stock market values to whether there is a “new economy,” and, among other things, to the causes of long-run economic divergence across nations. He is a prolific writer and has contributed more than 100 articles to publications ranging from The American Economic Review to Fortune and Foreign Affairs to The New York Times. His own website contains an impressive amount of material — including reviews of books and scholarly articles and analyses of current events — and is widely considered to be one of the best academic economics websites available. Brad DeLong lives in Lafayette, California, with his wife and two children.
