Abstract

In Europe, competition authorities have the power to close antitrust cases with “commitment decisions” after the concerned firms have offered agreed remedies. We show that the optimal use of this instrument is governed by a tradeoff between deterrence of potentially anticompetitive practices and early restoration of effective competition. We relate the optimal policy to the distribution of firm profit and consumer harm among cases. We find, however, that the optimal policy is generally not enforceable when the authority cannot credibly announce its policy prior to the firms’ strategic decisions. The lack of authority credibility may translate into insufficient or excessive use of commitment decisions.
