IOWE THANKS to everyone who played a role in the completion of this volume, especially the Fundación Grupo Mayan, whose generous support made possible its publication. In particular, there are two key individuals who brought this project to fruition: Daniel J. Chávez Morán, founder of the foundation, and Roberto Russell, its president. I would also like to thank the individual authors and everyone who participated in the November 2005 seminar in Buenos Aires—also titled “Explaining the Development Gap between Latin America and the United States”—for their thoughtful contributions. In addition to the authors, the seminar participants included Hernando De Soto, John W. Diamond, Pablo Guidotti, Celso Lafer, Juan Pablo Nicolini, Andrés Reggiani, Fernando Rocchi, Julio María Sanguinetti, Catalina Smulovitz, Ernesto Zedillo, and George Zodrow. Thanks are also due to Valeria Sobrino, who provided key logistical support, and Charles Roberts, who translated into English all of the chapters originally written in Spanish. Finally, special recognition is due to Guadalupe Paz, associate director of the Latin American Studies Program at SAIS, for her help in editing the English version of this volume and her general support of the project as a whole.
