This paper addresses the robustness of information sharing incentives of the Cournot oligopoly firms to differences in the cost functions and the quality of information. Specifically, we investigate (i) which firm has more incentive to share information, (ii) the conditions under which information sharing is mutually beneficial, and (iii) when it is not mutually beneficial, the conditions under which a firm gains enough to entice the unwilling firm into sharing information by compensation. We show that the firm with a less convex cost function has more incentives to share information, and present conditions for the latter two issues.
