TY - BOOK AU - Wauthy,Xavier TI - Competition and Regulation in Multisided Markets: Introduction PY - 2008///. N1 - 40 N2 - In this note, we offer an introduction to the economic analysis of multi-sided markets, i.e. markets characterized by cross network externalities. Building on a small set of recent contributions, we approach first a definition of multi-sidedness. Then, optimal pricing by multi-sided platforms is studied. Last, we discuss the implications of multi-sidedness for the implementation of competition policy.
