In this article I analyze strategic investment under uncertainty in a new market, where firms face a tradeoff between commitment and flexibility. The model predicts asymmetric equilibria under fairly general conditions, even though firms are ex ante identical and have symmetric opportunities to...

Various approaches used in Agent-based Computational Economics (ACE) to model endogenously determined interactions between agents are discussed. This concerns models in which agents not only (learn how to) play some (market or other) game, but also (learn to) decide with whom to do that (or not).

Economies are complicated systems encompassing micro behaviors, interaction patterns, and global regularities. Whether partial or general in scope, studies of economic systems must consider how to handle difficult real-world aspects such as asymmetric information, imperfect competition,...

I study the path properties of adaptive heuristics that mimic the natural dynamics of play in a game and converge to the set of correlated equilibria. Despite their apparent differences, I show that these heuristics have an abstract representation as a sequence of probability distributions that...

The paper is a survey of the Aumann's and Schelling's main contributions to game theory. For Aumann, a distinction is made between his works devoted to cooperative and non cooperative games. As for Schelling, pure coordination games and focal points are underlined on one hand, and the collective...

Robert Aumann's groundbreaking career in game theory has spanned over 35 years. These two volumes provide convenient access to all of his major research--from his doctoral dissertation in 1956 to papers as recent as January 1995. Threaded through all of Aumann's work (symbolized in his thesis on...

Aumann(1976) has shown that agents who have a common prior cannot have common knowledge of their posteriors for event E if these posteriors do not coincide. But given an event E, can the agents have posteriors with a common prior such that it is common knowledge that the posteriors for E *do*...

We consider the asymptotic value of two person zero sum repeated games with general evaluations of the stream of stage payoffs. We show existence for incomplete information games, splitting games and absorbing games. The technique of proof consists in embedding the discrete repeated game into a...
