Abstract

We provide a simple model of a three-sided market. In a departure from existing models of two-sided markets, our model highlights that an increase in competition on one side does not necessarily increase prices on other sides. The direction of a price change depends on the interdependency across different sides. The comparative statics from our model match recent empirical findings on the effect of Craigslist’s entry on US newspapers.
