摘要

In this paper, we establish existence and uniqueness results for equilibria in systems with an infinite number of agents and with local and global social interactions. We also examine the structure of the equilibrium distribution and derive a Markov property for the equilibrium distribution of a class of spatially homogeneous systems. (c) 2005 Elsevier Inc.
