This is an extensively revised version of two earlier papers that circulated as “A Theory of Firm Scope” and “Vision and Firm Scope.” Some of the material presented here formed part of the first author’s Munich Lectures (University of Munich, November 2001), Arrow Lectures (Stanford University, May 2002), Karl Borch Lecture (Bergen, May 2003), and Mattioli Lectures (Milan, November 2003). We are especially grateful to Andrei Shleifer for insightful comments. We would also like to thank Philippe Aghion, George Baker, Lucian Bebchuk, Pablo Casas-Arce, Mathias Dewatripont, Robert Gibbons, Louis Kaplow, Meg Meyer, David Scharfstein, Chris Snyder, Jeremy Stein, Lars Stole, Eric van den Steen, and seminar audiences at CESifo, University of Munich, Harvard University, London School of Economics, George Washington University, Stanford University, the Summer 2002 Economic Theory Workshop at Gerzensee, Switzerland, and the University of Zurich for helpful discussions.
