We owe our gratitude to the many people who have contributed invaluably
to the development of this book. This includes first and foremost The NASDAQ
OMX Educational Foundation, our editor at Columbia University Press,
Bridget Flannery-McCoy, Laura Miller, Kevin Haeberle, Menesh Patel, Anne
Choike, Yuan Zou, and Polina Dovman. Academically, we owe yet more debts.
Thanks to Larry Harris, whose Trading & Exchanges, served for so long as our
touchstone for lucidly teaching about market structure, to the Fellows of the
Columbia Program in the Law and Economics of Capital Markets, and to our
colleagues at Columbia University and the University of Michigan.
Most of the chapters in this book reflect work previously published in article
form, although all have been extensively revised and much has not been
published before. Thanks to the editors of those articles and to those cited in
their acknowledgments.
