A long-standing open question raised in the seminal paper of Kalai and Lehrer (1993) is whether or not the play of a repeated game, in the rational learning model introduced there, must eventually resemble play of exact equilibria, and not just play of approximate equilibria as demonstrated...

This paper analyses how competition over rebates for customer loyalty across product lines affects firms` pricing and consumers generally. If buyers incur firm specific costs or have shop specific tastes then competitive loyalty discounts lower consumer surplus overall and raise profits - the...

This paper evaluates whether immigration can mitigate the Dutch disease effects associated with booms in natural resource sectors.  We derive predicted changes in the size of the non-tradable sector from a small general-equilibrium model a la Obstfeld-Rogoff.  Using data for Canadian...

A new game theoretic analysis of finite horizon, complete information bargaining is advanced. The extensive form reflects an attempt to model unstructured negotiations, in which the negotiants can gain no artificial advantage from the details of the bargaining protocol. Conditions are identified...

Consider a finite data set where each observation consists of a bunde of contingent consumption chosen by an agent from a constraint set of such bundles.  We develop a general procedure for testing the consistency of this data set with a broad class of models of choice under risk and under...
