Detection and deterrence of collusion are longstanding antitrust problems, made difficult because collusive arrangements are usually surreptitious. In this paper, I discuss factors that facilitate or inhibit collusive schemes, as well as circumstances where detection is possible. I describe how industrial organization economists diagnose collusion (both explicit and tacit) among firms. Copyright Springer 2005
