This is a survey of the economic principles that underlie antitrust law and how those principles relate to competition policy. We address four core subject areas: market power, collusion, mergers between competitors, and monopolization. In each area, we select the most relevant portions of...

This paper studies model selection methods in the presence of nonstationarity. We focus on the Bayesian model selection rule and compare it with other criteria that are frequently used in econometric practice. First, we derive each of these criteria in the presence of nonstationarity. In...

I discuss the design and implementation of a SSNIP test in order toidentify the relevant market in a media market. I argue that in such atwo-sided market the traditional SSNIP test cannot be applied as it isusually conceived but rather should be modified in order to take intoaccount indirect...
