Acknowledgments

A book like this would not be possible without the assistance of many people, which we gratefully acknowledge.

First, the renowned team at Worth has spared no effort to help us; their experience and skill in publishing economics textbooks were invaluable. Numerous individuals have been involved with this project, but we must give special mention to a few: the project has been continually and imaginatively guided by acquisitions editor Sarah Dorger, publisher Chuck Linsmeier, development editor Bruce Kaplan, and by marketing manager Tom Digiano, who successfully brought the book to market. Through it all, the manuscript was improved endlessly by our primary development editor, Jane Tufts. We are greatly in their debt.

We have also relied on the assistance of a number of graduate students in collecting data for applications, preparing problems, and proofreading material. We would like to thank Leticia Arroyo Abad, Chang Hong, David Jacks, Alyson Ma, Ahmed Rahman, Seema Sangita, Radek Szulga, and Yingying Xu for their assistance. We are especially grateful to Benjamin Mandel, who has worked on many of the international trade chapters in the first edition; to Philip Luck, who worked on all the chapters in the second edition; and to Charles Liao, who worked on all the trade chapters in the third edition. Thanks also go to Christian Broda, Colin Carter, Michele Cavallo, Menzie Chinn, Sebastian Edwards, Ann Harrison, Mervyn King, Philip Lane, Karen Lewis, Christopher Meissner, Gian Maria Milesi-Ferretti, Michael Pakko, Ugo Panizza, Giovanni Peri, Eswar Prasad, Andrés Rodríguez-Clare, Jay Shambaugh, and Martin Wolf for providing data used in some of the applications and examples.

Special thanks go to Professor Francis Ahking, University of Conneticut, who once again carefully reviewed the page proofs of the entire book.
