Michael Wachter is a prominent cross-disciplinary scholar in the fields of law and economics, with his current research focusing on topics of corporate law, labor law and economics. Since 1970, when he joined the Penn faculty, he has held full professorships in three of Penn’s schools: Arts and Sciences, where he has been professor of economics since 1976; the Wharton School, where he was professor of management,1980-92; and the Law School, where he became professor of law and economics in 1984. In that year he also took on the directorship of the Institute for Law and Economics. Under his leadership, ILE has grown to become a nationally recognized center at the intersection of law and business, analyzing the impact of law on the global economy.  Wachter’s talents as an administrator have been recognized at the University level; he served as Deputy Provost of the University of Pennsylvania from July 1995 to January 1998, and as Interim Provost from January to December 1998.
