چکیده
A strong correlated equilibrium is a strategy pro le that is immune to joint deviations. Di erent notions of strong correlated equilibria were de ned in the literature. One major di erence among those de nitions is the stage in which coalitions can plan a joint deviation: before (ex-ante) or after (ex-post) the deviating players receive their part of the correlated pro le. In this paper we prove that if deviating coalitions are allowed to use new correlating devices, then an ex-ante strong correlated equilibrium is also immune to deviations at the ex-post stage. Thus the set of ex-ante strong correlated equilibria of Moreno & Wooders (1996) is included in all other sets of strong correlated equilibria.

All-stage strong correlated equilibrium
A strong correlated equilibrium is a correlated strategy pro le that is immune to joint deviations. Di erent notions of strong correlated equilibria have been de ned in the literature. One major di erence among those de nitions is the stage in which coalitions can plan a joint deviation: before (ex-ante) or after (ex-post) the deviating players receive their part of the correlated pro le.

متن کاملRisk Attitudes and Fairness: Theory and Experiment
I introduce an integrated model of risk attitudes and other-regarding preferences that extends the standard notion of inequity discount to lotteries. In this model, a decision maker perceives inequity partly by comparing the marginal risks she and others face. It predicts that fairness considerations will alter risk attitudes, in particular, a higher tolerance to positively correlated (fair) ri...
متن کاملAn ex ante control chart for project monitoring using earned duration management observations
In the past few years, there has been an increasing interest in developing project control systems. The primary purpose of such systems is to indicate whether the actual performance is consistent with the baseline and to produce a signal in the case of non-compliance. Recently, researchers have shown an increased interest in monitoring project’s performance indicators, by plotting them on the S...
متن کاملKnowledge spillover, licensing and patent protection
This paper investigates the effect of different patent regimes on R&D investment and social welfare in a duopoly market with uncertain R&D process. We find that strong patent protection increases R&D investment of at least one firm but whether both firms’ R&D investment will be more under strong patent protection is ambiguous. While ex-ante welfare is more likely to be higher under strong paten...
متن کاملEx post information rents in sequential screening
We study ex post information rents in sequential screening models where the agent receives private ex ante and ex post information. The principal has to pay ex post information rents for preventing the agent to coordinate lies about his ex ante and ex post information. When the agent’s ex ante information is discrete, these rents are positive, whereas they are zero in continuous models. Consequ...
