This paper provides a general model for the study of strategic knowledge sharing in any finite Bayesian game. Unlike earlier papers on strategic information revelation, higher-order uncertainties can be incorporated into the model. We propose an equilibrium concept, called knowledge equilibrium,...

Parikh and Krasucki (1990) suggested in an informal manner that a consensus does not require common knowledge. Weyers (1992) proved that their model does not permit such a conclusion and that a more general one has to be constructed. Heifetz (1996) gave an example with three agents inspired by...

In Bikhchandani, Hirshleifer, and Welch\'s (1992) specific model, it is showed that conformist behaviors can emerge due to information externalities. In this note we establish that this result, based on `informational cascades\', heavily depends on the choice of a particular tie-breaking...

This paper examines a game-theoretical model of parimutuel betting markets with asymmetric information. Generically, all Bayesian-Nash equilibria of the simultaneous game are characterized depending on the number of bettors and the quality of their private information. An equilibrium where all...

This paper studies the properties of endogenous information structures in some classes of Bayesian games in which a first stage of strategic information revelation is added. Sufficient conditions for the existence of perfectly revealing or non-revealing equilibria are characterized. In...

This paper analyzes a model of sequential parimutuel betting described as a two-horse race with a finite number of noise bettors and a finite number of strategic and symmetrically informed bettors. For generic objective probabilities that the favorite wins the race, a unique subgame perfect...

This paper examines strategic information revelation in a Cournot duopoly with incomplete information about firm~1\'s cost and information precision. Firm~2 relies on certifiable and ex post submissions of firm~1, without necessarily knowing whether firm~1 knows its cost or not. The sequential...

In persuasion games, it is well known that a perfectly revealing equilibrium may fail to exist when the decision maker is uncertain about the interested party\'s payoff-relevant information. However, by explicitly integrating higher order uncertainty into the information structure, this paper...

Sous l’impulsion, notamment, de l’essor de l’économie expérimentale, la littérature récente a mis en évidence un large éventail de situations dans lesquelles les incitations monétaires échouent à orienter les comportements dans le sens désiré. Ce constat conduit à rechercher...
