Information advantage in Cournot oligopoly

Ezra Einy, Diego Moreno, Benyamin Shitovitz

Research output: Contribution to journalArticlepeer-review


Consider an oligopolistic industry where firms have access to the same technology but are asymmetrically informed about the environment. Even though it is commonplace to think that in this context superior information leads to higher profits, we find that under Cournot competition this is not generally the case: It holds when firms' technology exhibits constant returns to scale, but it does not necessarily hold otherwise.
