My greatest debt is to Emily Martell, an undergraduate at William and Mary. She was my research assistant for the last eight months of work on the book. Her love of learning, her ability to write good prose, and her extraordinary intellect redounded to my great benefit and to the benefit of anyone who reads this book. Emily contributed to a few of the topics – the Enron debacle among them – and read the new network chapter and some others, each with great care. She responded to requests for help with alacrity and skill. Both her research and her critique of the manuscript were exemplary. She not only identified glitches, she drew my attention to passages that were not sufficiently clear. (“Glitch” is an understatement. She saved me from a horrible blunder in Chapter 4.) Emily even corrected my prose. I am deeply grateful for her help, and blessed to have had her as a colleague. Any defects that remain can be put down to the fact that I did not give her enough time to read the entire manuscript.
I am also thankful for the input of Steven Williams of the Department of Economics, University of Illinois, Lauren Merrill of the Boston Consulting Group, and my longtime colleague Jerry Kelly.
Over the last eight years I have benefitted from the excellent research assistance of Jennifer Boardman, Anthony Guth, Sarah Turner, and Gefoffrey Zinden. They were students in William and Mary's Masters in Public Policy program and my research assistants during their time here. The fruits of their labor can be found in the gray boxes containing the snippets that complement the formal analysis.
A number of William and Mary undergraduates have contributed to the third edition by suggesting improvements to its predecessor. I'm happy to be able to publicly thank Fasil Alemante, Daniel Byler, Bryan Callaway, Jimmy Cao, Sarah Gault, You-Suk Kim, Shane Mangin, Ruoyan Sun, Richard Uhrig, and especially Theresa Long. I'malso grateful to Simon Fung who, as a student at the University of London, drew my attention to an error in the second edition.
I salute my Cambridge University Press editors, Karen Maloney and Stephen Acerra, and editorial assistant Kristina Deusch. Their encouragement and guidance are much appreciated.
