This paper considers a model of endogenous growth with two sectors. It shows that it may be desirable to concentrate research in one sector, and so have unbalanced growth, but that the pressure of competition in research may cause the private sector to spread research too widely, and so have...

This paper examines the optimal structure of hierarchies when workers differ in the range of tasks they can perform. A hierarchical system may reduce costs by allowing most tasks to be handled by unskilled workers. This may however increase delay for those tasks which must pass through several...

We study the order of sale in art auctions. The final bid relative to the auctioneer's estimated price declines throughout the course of an auction. A theoretical model shows that in an auction ordered by declining valuation, even in the presence of risk-neutral strategic bidders, the price...

We analyse an infinite-period model of duopolistic competition in a market with consumer switching costs, in which in every period new consumers arrive and a fraction of old consumers leaves. We show that prices (and profits) are higher than in a market without switching costs, and that this...

This paper considers a simple adaptive learning rule in Bayesian games where players employ threshold strategies. Global convergence results are given for supermodular games and potentital games.

This paper uses the theory of large deviations to analyse equilibrium selection in one-dimensional games with large populations where the system evolves according to a jump Markov process. The equilibria selected maximise a quasi-potential function which can be determined by solving a polynomial...
