This paper addresses the question of what it takes to obtain a well-defined extensive form game. Without relying on simplifying finiteness or discreteness assumptions, we characterize the class of game trees for which all pure strategy combinations induce unique outcomes. The generality of the...

This paper considers bounded-memory players in a coordination game, who imitate the most successful remembered actions. With exogenous inertia, risk-dominant equilibria are selected independently of the length of memory. Without inertia, Pareto-dominant equilibria arise when memory is long enough.

We prove the existence of equilibria in games with players who employ abstract (non-binary) choice rules. This framework goes beyond the standard, transitive model and encompasses games where players have non-transitive preferences (e.g., skew-symmetric bilinear preferences).

We consider a pure exchange economy, where for each good several trading institutions are available, only one of which is market-clearing. The other feasible trading institutions lead to rationing. To learn on which trading institutions to coordinate, traders follow behavioral rules of thumb...

We consider a model of evolution with mutations as in Kandori et al. (1993) [Kandori, M., Mailath, G.J., Rob, R., 1993. Learning, mutation, and long run equilibria in games. Econometrica 61, 29–56], where agents follow best-response decision rules as in Sandholm (1998) [Sandholm, W., 1998....

We study competition among market designers who create new trading platforms, when boundedly rational traders learn to select among them. We ask whether ‘Walrasian’ platforms, leading to market-clearing trading outcomes, will dominate the market in the long run. If several market designers...

We consider a population of agents, either finite or countably infinite, located on an arbitrary network. Agents interact directly only with their immediate neighbors, but are able to observe the behavior of (some) other agents beyond their interaction neighborhood, and learn from that behavior...

We consider partial bandwagon properties in the context of coordination games to capture the idea of weak network externalities. We then study a local interactions model where agents play a coordination game following a noisy best-reply process. We show that globally pairwise risk dominant...
