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...

How do individuals with time-inconsistent preferences make consumption-savings decisions? We try to answer this question by considering the simplest possible form of consumption-savings problem, assuming that discounting is quasi-geometric. A solution to the decision problem is then a...

We consider a setting in which capital taxation is characterized by two distortions working in opposite directions. On one hand, governments engage in tax competition and are tempted to lower capital tax rates. On the other hand, they are unable to commit to future policies and, once capital has...

Can a government induce efficiency gains in domestic industry by protecting it against foreign competition? Would such trade protection be time-consistent? The present Paper builds a dynamic equilibrium model that accounts for learning-by-doing effects that link firms' strategies over time. The...

We introduce a form of pre-play communication that we call "preopening". During the preopening, players announce their tentative actions to be played in the underlying game. Announcements are made using a posting system which is subject to stochastic failures. Posted actions are publicly...

We show that for any market-clearing price, average profits in a symmetric industry cannot exceed the individual profits from the Walrasian output. This immediately implies that a firm itself can guarantee to beat the market by producing the Walrasian output. This property clarifies and...

We consider a selection process and a hierarchical institution in a dynamic model as in Harrington [3], where agents are "climbing the pyramid" in a rank-order contest based on the "up or out" policy. Agents are ranked according to the quality of their performances in a particular environment...

This paper gives a new method to characterize Markov Perfect Nash Equilibrium in stochastic differential games by means of a set of Generalized Euler Equations. Necessary and sufficient conditions are given.

An individual's learning rule is completely uncoupled if it does not depend on the actions or payoffs of anyone else.  We propose a variant of log linear learning that is completely uncoupled and that selects an efficient pure Nash equilibrium in all generic n-person games that possess at least...

We analyze a stochastic versions of the Rubinstein bargaining model with outside options available to both the proposer and the responder.
