Asynchronicity and Coordination in Common and Opposing Interest Games

Article

Calcagno, Riccardo | KAMADA, Yuichiro | LOVO, Stefano | TAKUO, Sugaya

We study games endowed with a pre-play phase in which players prepare the actions that will be implemented at a predetermined deadline. In the preparation phase, each player stochastically receives opportunities to revise her actions, and the finally-revised action is taken at the deadline. In 2-player \textquotedblleft common interest" games, where there exists a best action profile for all players, this best action profile is the only equilibrium outcome of the dynamic game. In \textquotedblleft opposing interest" games, which are $2\times 2$ games with Pareto-unranked strict Nash equilibria, the equilibrium outcome of the dynamic game is generically unique and corresponds to one of the stage-game strict Nash equilibria. Which equilibrium prevails depends on the payoff structure and on the relative frequency of the arrivals of revision opportunities for each of the players.

This paper studies the effect of asymmetric information on the price formation process in a quote-driven market. One market-maker receives private information on the value of the quoted asset and repeatedly competes with market-makers who are uninfor...

Working Paper

We introduce a form of pre-play communication that we call "preopening". During the preopening, players announce their tentative actions to be played in the underlying game. Announcements are made using a posting system which is subject to stochastic...

Belief-Free Equilibria In Games With Incomplete Information

LOVO, Stefano ; HORNIER, Johannes - GROUPE HEC 20060101 - 31 P.

Working Paper

We define belief-free equilibria in two-player games with incomplete information as sequential equilibria for which players’ continuation strategies are best-replies, after every history, independently of their beliefs about the state of nature. We c...
