Large strategic dynamic interactions

Abstract

The paper presents a model of large strategic dynamic interactions in an environment with uncertain fundamentals. The interaction is among a large finite group of interdependent players, diversified in their preferences and information. We study an imagined-continuum equilibrium, a behavioral hybrid of games with a continuum of players and finite games. This equilibrium enables simple Bayesian reasoning and admits natural Markov-perfect equilibria. In addition, we establish bounds on the probabilistic discrepancies between players' beliefs that are derived from the continuum model and the actual finite reality.
