Endogenous interval games in oligopolies and the cores

摘要: In this article we study interval games in oligopolies following the γ-approach. First, analyze their non-cooperative foundation and show that each coalition is associated with an endogenous real interval. Second, Hurwicz criterion turns out to be a key concept provide necessary sufficient condition for non-emptiness of induced core solution concepts: standard γ-cores. The first permits ascertain even linear symmetric industries γ-core empty. Moreover, by means approximation technique quadratic Bezier curves prove second always holds, hence non-empty, under natural properties profit cost functions.
