Dillon Professor of Government Graham T. Allison '62 and Ford Foundation Professor of Science and International Affairs Ashton B. Carter have also been rumored to be up for State Department posts.

The growing Kennedy School vacuum, though, is slowly being filled by the arrival of several former Bush administration officials.

Former Secretary of Labor Lyn Martin, former National Security Council members Phillip Zeliko and Robert Blackwill, former Rep. Mickey Edwards (R-Okla.), and former Deputy Assistant to the President and Director of the White House Office of Policy Development Roger B. Porter will join the Kennedy School faculty, said Singer.

Porter was IBM Professor of Business and Government at the Kennedy School prior to his Bush Administration appointment, and his return to that post is indicative of the revolving-door phenomenon associated with Harvard and the federal government.

Singer said that those leaving are likely to return. "They're excited about joining the government and will value the experience," he said. "But they're academics at heart."

Both Reich and Nye have served in previous Democratic administrations, the former as director of policy planning for the FTC under president Jimmy Carter and assistant to the solicitor general under president Gerald Ford; the latter, as undersecretary of state for security assistance, science, and technology in the Carter administration.

The Clinton appointments are also thinning the ranks of FAS, and more professors are on the way, said J. Bradford De Long, Danziger associate professor of economics.

De Long said chances are "pretty high" he'll be tapped for a policy analysis and forecasting post in the Treasury department, joining several Harvard economists already in the Clinton camp.

"The exodus is likely to grow," he said of the FAS appointments. "The first wave is gone, but there's a second, bigger wave, and there will be a third wave at the end of the year and a fourth wave next year."

He said the University will see big gaps in its economics and other departments.

"You're going to lose a lot of people from the social sciences," he said. De Long sees a sort of "snowball effect" happening, as Harvard experts already in Washington import their colleagues and students.

Professor of Economics N. Gregory Mankiw has also noted the snowball effect: three economics professors currently nominated for posts: Ropes Professor of Political Economy Laurence H. Summers, Professor of Economics Lawrence F. Katz and Instructor in Economics David M. Cutler have often worked together in the past.

"Each of these people got involved through each other," he said. "All three have coauthored papers together... They have a lot of interests in common."

Summers has been nominated as undersecretary of treasury, Cutler has been tapped as liaison between the Council of Economic Advisors and the National Economics Council, which in turn is chaired by Robert E. Rubin '60, a former co-chair of Goldman Sachs Co. who still serves on Harvard Management Company's board of directors. Katz has been called as chief economist in the Labor department.
