In this paper, the authors explain the “hypothetical monopolist test” that has become the standard methodology for identifying relevant antitrust markets in merger cases, and discuss two approaches to implementing the test.

This paper is forthcoming, as edited, in Antitrust Economics for Lawyers (LexisNexis), Chapter 1.
