The experimental literature on antitrust enforcement provides robust evidence that communication plays an important role for the formation and stability of cartels. We extend these studies through a design that distinguishes between innocuous communication and communication about a cartel,...

We report results of a series of experiments designed to test the stability of the best reply process. With linear demand and cost functions, the process is stable if and only if there are less than three firms in the market. However, we find no experimental evidence of such instability in a...

We report results of experiments designed to test the predictions of the best reply process. In a Cournot oligopoly with four firms, the best reply process should theoretically explode if demand and cost functions are linear. We find, however, no experimental evidence of such instability....
