Managing Cartels: how Cartel Participants Create Stability in the Absence of law

Firms enter cartels (e.g. price-fixing; bid-rigging) in order to control market uncertainties and gain collusive profits, but face challenges in controlling the cartel itself. A challenge for business cartels is how to organise collective illegal activities without the use of formal control, such as binding legal contracts or arbitration.

This article addresses how informal coordinating mechanisms enable cartel stability outside the scope of formal legal control. Based on an in depth study of 14 Dutch cartels, this article shows the importance of informal social mechanisms to coordinate, monitor, enforce, and compensate for the longevity of business cartels. Furthermore, the results emphasise that in order to explain cartel stability, social mechanisms that induce trust need to be considered
