Incentive Compatible Collusion and Investment∗
نویسندگان
چکیده
We consider a two-stage model in which two firms first invest in R&D to reduce their marginal production costs, and then either compete or collude in the output market. When they collude, they bargain over a cartel agreement to divide the collusive profit. If bargaining breaks down, they revert to duopolistic competition. For both a location model and a linear demand model, we show that firms invest more in R&D in the first stage under collusion than under competition. We demonstrate via example that social welfare may be greater under collusion than under competition in the location model. c © 2005 Peking University Press

Collusion constrained equilibrium
We study collusion within groups in noncooperative games. The primitives are the preferences of the players, their assignment to nonoverlapping groups, and the goals of the groups. Our notion of collusion is that a group coordinates the play of its members among different incentive compatible plans to best achieve its goals. Unfortunately, equilibria that meet this requirement need not exist. W...
متن کاملGeneric efficiency and collusion-proofness in exchange economies
The purpose of this paper is to study the kind of e‰cient allocations that can be achieved in exchange economies with asymmetric information, by means of a decentralized mechanism robust to coalitional, strategic deviations. To this end, we define a new strategic equilibrium concept – called strong collusion-proof contract – designed to characterize stable communication agreements in games with...
متن کاملRobustly Collusion-Proof Implementation
A contract with multiple agents may be susceptible to collusion. We show that agents’ collusion imposes no cost in a large class of circumstances with risk neutral agents, including both uncorrelated and correlated types. In those circumstances, any payoff the principal can attain in the absence of collusion, including the secondbest level, can be attained in the presence of collusion in a way ...
متن کاملFS IV 99 - 10 Collusion with Private and Aggregate Information
Collusion with Private and Aggregate Information by Jim Y. Jin* This paper considers three linear asymmetric oligopoly models with (i) a representative consumer, (ii) horizontal differentiation and (iii) vertical differentiation. We show that firms could maximize the joint-profit only based on private and aggregate information. They can choose the “correct“ colluding prices without knowing the ...
متن کاملMechanisms for Making Crowds Truthful
We consider schemes for obtaining truthful reports on a common but hidden signal from large groups of rational, self-interested agents. One example are online feedback mechanisms, where users provide observations about the quality of a product or service so that other users can have an accurate idea of what quality they can expect. However, (i) providing such feedback is costly, and (ii) there ...
