* Assistant Professor of Law, University of Pennsylvania Law School. In writing this piece, I
benefitted enormously from the insightful comments and criticisms of Bernie Black, Ken Davis, Pat
Gudridge, Marcel Kahan, Mike Klausner, Reinier Kraakman, Seth Kreimer, Stephen Morse,
Michael Wachter, and Elizabeth Warren, and from faculty workshops at the University of Miami
and the University of Pennsylvania law schools. I am also grateful to Jonathan Ashley for very able
research assistance. Financial support for this research was provided by the University of Penn-
sylvania Law School's Institute for Law and Economics.
