The degree of collusiveness of a market with consumer switching costs is studied in an infinite-horizon overlapping-generations model of duopolistic competition. In contrast to previous models of switching costs, this paper assumes that firms compete for the demand for a homogeneous good by...

I show that exclusive, staggered supply contracts can decrease industry competition when there are economies of scale: buyers pay a higher price to the incumbent seller and the expected value received by an entrant seller is lower when contracts are staggered. Moreover, under staggered contracts...

We provide a general model of dynamic competition in an oligopolistic industry with investment, entry, and exit. To ensure that there exists a computationally tractable Markov perfect equilibrium, we introduce firm heterogeneity in the form of randomly drawn, privately known scrap values and...

We study the evolution of prices set by duopolists who are uncertain about the perceived degree of product differentiation. Customers sometimes view the products as close substitutes, sometimes as highly differentiated. As the informativeness of the quantities sold increases with the price...

We analyze the effect of the projected demographic transition on the political support for social security, and equilibrium outcomes. Embedding a probabilistic-voting setup of electoral competition in the Diamond (1965) OLG model, we find that intergenerational transfers arise in the absence of...

We study a game of strategic experimentation with two-armed bandits where the risky arm distributes lump-sum payoffs according to a Poisson process. Its intensity is either high or low, and unknown to the players. We consider Markov perfect equilibria with beliefs as the state variable. As the...

This Paper considers the financing of a research project under uncertainty about the time of completion and the probability of eventual success. The uncertainty about future success diminishes gradually with the arrival of additional funding. The entrepreneur controls the funds and can divert...

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 equilibria are essential and strongly stable. Moreover,...

This Paper studies a game of strategic experimentation with two-armed bandits whose risky arm might yield a pay-off only after some exponentially distributed random time. Because of free-riding, there is an inefficiently low level of experimentation in any equilibrium where the players use...

We compare steady states of open loop and locally stable Markov perfect equilibria (MPE) in a general symmetric differential game duopoly model with costs of adjustment. Strategic incentives depend on whether an increase in the state variable of a firm hurts or helps the rival and on whether...
