The Effects of Private Damage Claims on Cartel Activity: Experimental Evidence

This may stabilize cartels. We run an experiment to study this issue. Firms choose whether to join a cartel, may apply for leniency afterward, and then potentially face private damages. We find that the implementation of private damage claims reduces cartel formation but makes cartels indeed more stable. The negative effect of damages is avoided in a novel setting where the whistleblower is also protected from damages.
