Supplement to Platform Economics: The Economics of Multi-Sided Businesses

Oct 16, 2013


I’ve written the following articles on multi-sided platforms since the publication of Platform Economics: Essays on Multi-Sided Businesses in December 2011. Hopefully, you’ll find them useful.

The first article, the “Antitrust Analysis of Multi-Sided Platforms,” provides a survey of the literature on multi-sided platforms that is relevant to competition policy through the end of 2012. The second article, “The Consensus Among Economists on Multi-Sided Platforms,” argues that courts and competition authorities should reject economic “evidence” that ignores the widely accepted teachings of the multi-sided literature. The other three articles cover different aspects of multi-sided platforms. “Governing Bad Behavior” is about the use of rules and regulations by platforms to govern their communities. “Economics of Vertical Restraints for Multi-Sided Platforms” examines the pro-competitive and anti-competitive explanations for vertical restraints for platforms. “Attention Rivalry Among On Line Platforms” shows how seemingly different online platforms compete for harvesting consumer attention and selling this to advertisers.
