a year on a research fellowship at the University of Oxford, where he was a member of Merton College. Career Early career Roberts began his career with teaching assignments at Virginia Polytechnic Institute, the University of New Mexico, Stanford University, and Tulane University. He was a professor of business administration and professor of economics at George Mason University and was the inaugural William E. Simon Chair in Political Economy at Georgetown University, serving for 12 years. While a visiting professor at Georgetown University, he was hired as economics counsel to United States Congressman Jack Kemp, later also serving as economics counsel to United States Senator Orrin Hatch, as staff associate with the Defense Appropriations Subcommittee, and as chief economist with the minority staff of the United States House of Representatives Committee on the Budget. He has been credited as the primary author of the original draft of the Economic Recovery Tax Act of 1981. During this time, he also contributed columns to Harper's and The New York Times and served as associate editor of The Wall Street Journals opinion page. Later career In December 1980, along with Alan Greenspan and Herbert Stein, Roberts was one of the three speakers at the two-day National Forum on Jobs, Money and People at the Innisbrook Resort and Golf Club in Palm Harbor, Florida. Two months later, in 1981, he was appointed by President of the United States Ronald Reagan as Assistant Secretary of the Treasury for Economic Policy. As Assistant Treasury Secretary he was a driver behind the economic policy of the first term of the Reagan administration and was lauded as the "economic conscience of Ronald Reagan". Nonetheless, his singular zealousness for supply-side economics provoked ire in some quarters within the government, with Larry Kudlow – then an official in the Office of Management and Budget – saying that "Craig saw himself as the keeper of the Reagan flame. Only Craig knew what was right. No one else knew what was right". Roberts' concern about U.S. budget deficits led him into conflict with other Reagan-era officials such as Martin Feldstein and David Stockman. Roberts resigned in February 1982 to return to academia. He was a senior research fellow at the Hoover Institution, from 1983 to 1993 was the William E. Simon Chair in Political Economy at the Center for Strategic and International Studies and, from 1993 to 1996, a distinguished fellow at
