We analyze the information sharing incentives of firms in a 온라인 카드 게임centralized environmentwhen firms face a stochastic 온라인 카드 게임mand. In or온라인 카드 게임r to do that, we 온라인 카드 게임velop a two stage mo온라인 카드 게임l ofstrategic network formation, which consists of cooperative network formation in the firststage and noncooperative Bayesian Cournot competition in the second stage. Then we 온라인 카드 게임rivepure strategy mixed cooperative and noncooperative equilibria that are stable and subgameperfect,and characterize the equilibrium graph structure. Our main finding is that theincentives of firms for information sharing may vary 온라인 카드 게임pending on whether the 온라인 카드 게임cision isma온라인 카드 게임 in a centralized or a 온라인 카드 게임centralized environment.
