David A. Moss is the John G. McLean Professor at Harvard Business School, where he teaches in the Business, Government, and the International Economy unit. Moss graduated from Cornell University (B.A., 1986) and went on to earn an M.A. in economics (1988) and a Ph.D. in history (1992) from Yale University. In 1992 and 1993, he served as a senior economist at Abt Associates, a public policy consulting firm based in Cambridge, Massachusetts. He joined the Business School faculty in July, 1993.

Professor Moss's research focuses on economic policy and especially the government's role as a risk manager. He has published three books on these subjects: Socializing Security: Progressive-Era Economists and the Origins of American Social Policy (Harvard University Press, 1996), which traces the intellectual and institutional origins of the American welfare state; When All Else Fails: Government as the Ultimate Risk Manager (Harvard University Press, 2002), which explores the government's pivotal role as a risk manager in policies ranging from limited liability and bankruptcy law to social insurance and federal disaster relief; and A Concise Guide to Macroeconomics: What Managers, Executives, and Students Need to Know (Harvard Business School Press, 2007), a primer on macroeconomics and macroeconomic policy.

In addition to these books, Moss has co-edited two volumes and has published numerous articles, book chapters, and case studies, mainly in the fields of institutional and policy history, financial history, political economy, regulation, and comparative social policy. One recent article, "An Ounce of Prevention: Financial Regulation, Moral Hazard, and the End of ‘Too Big to Fail'" (Harvard Magazine, Sept-Oct 2009), grew out of his research on financial regulation and regulatory reform for the TARP Congressional Oversight Panel. He has also created a financial history course in the second year of the Harvard MBA program entitled "Creating the Modern Financial System," which traces major developments in financial markets, institutions, and instruments from the early eighteenth century to today.

Professor Moss is the founder of the Tobin Project, a non-profit research organization, and a member of the National Academy of Social Insurance. Recent honors include the Robert F. Greenhill Award, the Editors' Prize from the American Bankruptcy Law Journal, the Student Association Faculty Award for outstanding teaching at the Harvard Business School, and the American Risk and Insurance Association's Annual Kulp-Wright Book Award for the "most influential text published on the economics of risk management and insurance."
