Blowing the Whistle

Abstract

Leniency clauses, offering cartelists legal immunity if they blow the whistle on each other, is a recent anti-trust innovation. The authorities wish to thwart cartels and promote competition. This effect is not evident, however; whistle-blowing may enforce trust and collusion by providing a tool for cartelists to punish each other. We examine the impact of leniency law, and other rules, theoretically and experimentally.Anti-trust; leniency; immunity; amnesty; blow the whistle; cartels; price competition; Bertrand model; experiment; communication
