Abstract

We propose a strategy to identify structural parameters in infinitely repeated games without relying on equilibrium selection assumptions. We exploit the extreme points of the equilibrium payoff set to construct bounds on the frequencies of stage game actions, which then impose restrictions on the parameters of interest. To illustrate the identification strategy, we use an infinitely repeated Prisoners Dilemma to get bounds on a utility parameter and a common discount factor.
