演講摘要 : While deliberate cheating and inter-firm compensation are often observed in the real-world cartels, existing literature fails to explain both in a unified framework. This paper aims to provide a theoretical explanation of “cheating and compensation on-path of play" using a canonical model of price-fixing collusion. The novel mechanism relies on firms playing mixed strategies allowing for coordination on monopoly price and price-cutting to happen with positive probability, together with a compensation scheme that punishes price-cutters. The mechanism is optimal in a restricted class of equilibria, and such price-cutting and compensation are necessary parts for any symmetric collusive equilibrium.
