In preparing this book, we extensively revised some articles that initially appeared in the following places. Eric A. Posner and Cass R.

Also thanks to Richard Stewart, Michael Vandenbergh, and anonymous referees for comments on the entire manuscript. We also thank Kathryn Burger, Lena Cohen, and Katie Reaves for research assistance and our dean, Saul Levmore, for financial support.
