New eBook on Two-Sided Markets Now Available, Gratis, to Our Community
The area of two-sided markets is one of the hottest in economics and especially pertinent to the field of antitrust. In fact, the first academic paper on the subject (by William Baxter in 1983) was inspired by a study of the antitrust issues involving credit card interchange fees. Jean-Charles Rochet & Jean Tirole pursued this lead, eventually coining the term “two-sided markets.” Over the years, we’ve discovered that one of the problems with two-sided market analysis is that it is hard to find formal limiting principles (not uncommon in economics). Sometimes a two-sided market perspective is highly informative while other times it isn’t. It matters when it matters. What’s now very clear, with the benefit of a decade of work, is that the study of multi-sided platforms has provided valuable insights to economists, policymakers, and business people.

To bring our readers up to date on two-sided market studies, we’re presenting three collections. The first is a collection of papers by David S. Evans presented in an easily downloadable eBook format, Essays on the Economics of Two-Sided Markets.* Part I presents background pieces on the economics of multi-sided platforms and industries in which these platforms are common. Part II examines the antitrust economics of two-sided markets including the difficult problem of defining the boundaries of competition. Part III comprises several papers that apply two-sided market analysis to web-based businesses. Part IV does the same for payment cards which is the industry that attracted much of the early two-sided analysis-in part because this framework was helpful for understanding the hotly debated issue of interchange fees. Part V collects several article and book chapters on software platforms. These platforms have become especially important in the last several years because they are now the basis for revolutionary developments with mobile devices (e.g. the iPhone and Android), social networking (Facebook in particular), and payments (PayPalX). The essays are published as originally written.
