We examine local stability under learning of stationary Markov sunspot equilibria (SSEs) in a simply dynamic nonlinear model. Necessary and sufficient conditions for local convergence of a recursive learning algorithm to SSEs are shown to be given (generically) by expectational stability...

This paper looks at connections between Renegotiation Proof Equilibrium sets for finitely and infinitely repeated games. We look at the Benoit and Krishna (1993) definition of renegotiation proof sets for discounted finitely repeated games. We focus on the long run behaviour of these sets for...

We consider the impact of history on the survival of a monopolist selling single units in discrete time periods, whose quality is learned slowly. If the seller learns her own quality at the same rate as customers, a sufficiently bad run of luck could induce her to stop selling. When she knows...

This paper centres around the question of ownership of firms and managerial competition and how these affect manager and employees' incentives to invest in human capital. We argue that employee's incentives in human capital investment are affected by both ownership and competition since both...

There are two parts to this paper. Part One introduces the subject of implementation, and provides applications (in particular, to the theory of contracts). This part is written so as to be accessible to the general reader. Part Two surveys the literature, and is somewhat more formal.

We study a contracting model with unforeseen contingencies in which the court is an active player. Ex-ante, the contracting parties cannot include the risky unforeseen contingencies in the contract they draw up. Ex-post the court observes whether an unforeseen contingency occurred, and decides...
