This paper studies implementation of the social optimum in a model of addictive consumption. We consider corrective taxes that address inefficiencies due to negative externalities, imperfect competition, and self-control problems. Our setup allows us to evaluate how such taxes are affected by...

This paper examines monopolistic behavior in a framework with dynamic demands. We show that time consistent output and pricing policies yield different equilibrium outcomes in terms of profits and welfare. In a simple two-period model, we find that pricing policies impose less restrictive...

This paper examines monopolistic behavior in a framework with habit formation and consumer commitment. We show that time consistent output and pricing policies yield di®erent market outcomes. Policy selection determines the strategic properties of the producer's intra-personal game: current and...

This paper analyzes time-consistent subsidies in industries with strong learning effects and frequent entry and exit. Structural dynamics create opportunities for strategic behavior: by influencing government policies, infant firms can reduce their tax burden and weaken future competitors. Two...

This paper studies implementation of the social optimum in a model of habit formation. We consider taxes that address inefficiencies due to negative consumption externalities, imperfect competition, and self-control problems. Our contributions are to: i) account for producers’ market power;...

A holdup model is analyzed in which one party, the seller, has an investment project that the other party, the buyer, can subsidize. The investment project remains the seller's; she cannot transfer her entire control rights to it. In particular, she can always refuse to allow the buyer to...

When univariate methods are applied to real exchange rates, point estimates of autoregressive coefficients typically imply very slow rates of mean reversion. Rogoff (1996) discusses that the remarkable consensus of 3-5 year half-lives of purchasing power parity (PPP) deviations is found among...
