Corporations are the productive engine of market economies. Yet the rules by which the wealth generated by corporations gets divided between the providers of financial capital and the providers of human capital are poorly understood.In this colloquium, a group of economists, social scientists, lawyers, labor relations specialists, business executives, and executives of financial institutions debate questions about the allocation of risks, returns, and rights in corporations that were raised in Margaret Blair’s prior book, Ownership and Control: Rethinking Corporate Governance for the Twenty-First Century (Brookings, 1995).In addition to Margaret Blair, participants include Bernard Aidinoff, Amatai Etzioni, Ronald Gilson, Martin Ginsburg, Mark Goyder, Oliver Hart, Bruce Householder, Tony Jackson, Bevis Longstreth, Jonathan Low, Bruce Mac Laury, Ira Millstein, Nell Minow, Charles Rossotti, Charles Schultze, Kenneth West, and Sidney Winter. Roswell Perkins, of the New York law firm of Debevoise & Plimpton, served as moderator.
