We study the role of communication within a cartel. Our analysis is carried out in Stigler’s (1964) model of repeated oligopoly with secret price cuts. Firms observe neither the prices nor the sales of their rivals. For a fixed discount factor, we identify conditions under which there are equilibria with “cheap talk” that result in near-perfect collusion, whereas all equilibria without such communication are bounded away from this outcome. In our model, communication improves monitoring and leads to higher prices and profits.

We study an R&D race between an established firm and a startup under asymmetric information. R&D investment brings success stochastically, but only if the innovation is feasible. The only asymmetry is that the established firm has better information about the feasibility of the innovation. We show that there is an equilibrium in which the poorly informed startup wins more often, and has higher expected profits, than the better-informed incumbent. When the informational asymmetry is large, this is the unique equilibrium outcome. The channel by which better information becomes a competitive disadvantage appears to be new and stems from the fact that better information dulls the incentive to learn from one’s rival.
