The economic recessions since 1973 have emphasised the interdependence of the major economies and their policy choices. This paper examines whether decentralised control of the world economy effectively limits our ability to manage individual economies. It is well known that noncooperative...

This paper studies the diffusion of a new technology that is brought to market while its potential is still uncertain. We consider a dynamic game in which firms improve both a new and a rival old technology while learning about the relative potential of both technologies. We use the model to...

Learning-by-doing and organizational forgetting have been shown to be important in a variety of industrial settings. This paper provides a general model of dynamic competition that accounts for these economic fundamentals and shows how they shape industry structure and dynamics. Previously...

We examine buyer strategic power in the model of dynamic Bertrand-Edgeworth competition. Two sellers with a limited inventory sell to a single buyer, who has a consumption opportunity in each period. The market power of the sellers is offset by the strategic power of the buyer. By not consuming...

A large portion of innovators do not patent their inventions. This is a relative puzzle since innovators are often perceived to be at the mercy of imitators in the absence of legal protection. In practice, innovators however invest actively in making their products technologically hard to...

With applied work in mind, we define an equilibrium notion for dynamic games with asymmetric information which does not require a specification for players' beliefs about their opponent types. This enables us to define equilibrium conditions which, at least in principal, are testable and can be...

We study political compromise founded on tacit cooperation. Two political parties must share a fixed pie in each of an infinite sequence of periods. In each period, the party in power has ultimate authority to divide the pie. Power evolves according to a Markov process among a set of political...

We consider a model in which two countries are involved in arms accumulation. The West is a decentralized market economy whose government uses optimal taxation to provide a public good, defense. The East is a centrally planned economy. Utility depends on consumption, leisure and defense; defense...

The world's industrialised economies have become increasingly interdependent over the past 30 years. The policy implications of this mutual dependence obviously depend on the spillover effects between economies: but work on this topic has used simplified models of hypothetical economies, and has...

We characterize the open-loop and the Markov-Perfect Stackelberg equilibria for a differential game in which a cartel and a fringe extract a non-renewable resource. Both agents have stock dependent costs. The comparison of initial market shares, across different equilibria, depends on which firm...
