In this paper we show that existence of a Markov perfect equilibrium (MPE) in the Ericson & Pakes (1995) model of dynamic competition in an oligopolistic industry with investment, entry, and exit requires admissibility of mixed entry/exit strategies, contrary to their assertion. This is...

We model a dynamic limit order market as a stochastic sequential game. Since the model is analytically intractable, we provide an algorithm based on Pakes McGuire (2001) to find a stationary equilibrium, we generate artifical time series and perform comparative dynamics. As we know the data...

This paper develops a relatively simple method for computing the Markov Perfect Equilibria of dynamic games with asymmetric information (see Maskin and Tirole (1992, 2001)). We consider a class of dynamic games in which there is finite number of active players in each period, each characterized...

In the canonical learning model, the multi-armed bandit with independent arms, a decision maker learns about the different alternatives only through his private experience. It is well known that any optimal experimentation strategy for this problem is ex-post inefficient: it sometimes leads the...

We present a dynamic quantity setting game, where players may continuously adjust their quantity targets, but incur convex adjustment costs when they do so. These costs allow players to use quantity targets as a partial commitment device. We show that the equilibrium path of such a game is...

This paper develops and structurally estimates a learning model in which firms acquire information about workers' ability by observing their performance over time. A firm consists of a collection of jobs which differ in the informational content of performance, as measured by the dispersion in...

In a frictional labor market, when an employee receives an outside offer, his employer is naturally tempted to compete to retain him. Casual observation in the labor market, however, suggests that this type of ex post competition is rare. As a consequence, employers often let valuable employees...

Why would a political elite voluntarily dilute its political power by extending the voting franchise? This paper develops a dynamic recursive framework for studying voter enfranchisement. We specify a class of dynamic games in which political rights evolve over time. Each period, private...
