Ten years of Merger Guidelines: A retrospective,critique, and prediction

The period since the 1982 Merger Guidelines is surveyed and assessed, including the 1992 Merger Guidelines. The 1982 Guidelines were an improvement in economic underpinnings and in merger policy, but the Guidelines' focus on short run market power is not a sensible basis for merger policy. The 1992 Guidelines continue this focus on short run market power, attempt to provide some clarifications of current enforcement policy, but add some questionable economics to the stew. The merger policy laid out in the 1992 Guidelines will not survive, since it does not suitably come to grips with the fundamental bases of the social costs and benefits of mergers and ignores ‘competitiveness’ issues.
