This paper develops a theory of regular Markov perfect equilibria in dynamic stochastic games. We show that almost all … dynamic stochastic games have a finite number of locally isolated Markov perfect equilibria that are all regular. These …

In aggregative games, each player's payoff depends on her own actions and an aggregate of the actions of all the … players (for example, sum, product or some moment of the distribution of actions). Many common games in industrial … organization, political economy, public economics, and macroeconomics can be cast as aggregative games. In most of these situations …
