Free Economics Textbook

R. Preston McAfee, the J. Stanley Johnson Professor of Business, Economics & Management at the California Institute of Technology, has written an excellent economics textbook entitled Introduction to Economic Analysis. This book is above the level of the standard intermediate undergraduate textbook but not at the level of a doctoral textbook like Kreps or Mas-Colell, Whinston, and Green. It covers the material with lots of applications, and uses calculus to demonstrate a wide set of examples. The most astounding part of this text the the wide breadth of material it covers, including traditional economics topics, plus several others such as game theory, auctions, and antitrust. Professor McAfee has made this book free to the public, so I encourage you to check it out.
