Allowing the upstream firm to chat privately with each downstream firm reduces … total offered quantity from near the Cournot level (observed in the absence of communication) halfway toward the monopoly … bargaining advantage from open communication that all of the gains from monopolizing the market accrue to them.

As a result, the payoff gain … from communication increases with the number of firms, at a decreasing rate. …

This paper characterizes geometrically the set of all Nash equilibrium payoffs achievable with unmediated communication …

We explore the difference between explicit and tacit collusion by investigating the impact communication has in … largest additional profit from talking. We also find that industries continue to collude successfully after communication is … disabled. Communication supports fims in coordinating on collusive pricing schemes, and it is also used for conflict mediation. …

In a Bertrand-oligopoly experiment, firms choose whether or not to engage in cartel-like communication and, if so, they …
