We analyze a model of conflict with endogenous choice of effort, where subsets of the contenders may force the resolution to be sequential: First the alliance fights it out with the rest and – in case they win – later they fight it out among themselves. For three-player games, we find that...

We extend Milgrom and Weber’s affiliated valuations model to the multi-unit case with constant marginal valuations where 2 bidders compete for k identical objects. We show that the discriminatory auction has a unique equilibrium, that corresponds to Milgrom and Weber’s firstprice...

In this paper, we investigate whether, because of differing social organisation, the effect of greater equality may have opposing effects on economic growth in different societies. We investigate a simple endogenous growth model where agents care about their status. This is determined by their...

In Grameen Bank's group lending arrangement, all agents within a group do not borrow at the same time. Agents within a group, queue for credit and their credit is conditional on successful repayments of the previous loans. In a group lending model, where all group members borrow in the same time...

We study learning in a large class of complete information normal form games. Players continually face new strategic situations and must form beliefs by extrapolation from similar past situations. We characterize the long-run outcomes of learning in terms of iterated dominance in a related...

We investigate the relationship between the continuous time best response dynamic, its perturbed version and evolutionary dynamics in relation to mixed strategy equilibria. We find that as the level of noise approaches zero, the perturbed best response dynamic has the same quantitative...

In the presence of local public goods differences in tastes are an important determinant of the way in which partnerships are formed. Heterogeneity in tastes for private vs. public goods produces a tendency to positive assortment and partnerships of couples with similar tastes; heterogeneity in...

We report experiments designed to test the theoretical possibility, first discovered by Shapley (1964), that in some games learning fails to converge to any equilibrium, either in terms of marginal frequencies or of average play. Subjects played repeatedly in fixed pairings one of two 3 × 3...

This paper analyses comparative statics for two classes of n-player games of incomplete information with continuous action spaces. The two classes are defined by differences in the payoff and behaviour of the weakest type: the lowest value bidder or highest cost firm. We show that in ``weakly...

We examine the commitment effect of delegated bargaining when the delegation contract is renegotiable. We consider a seller who can either bargain face-to-face with a prospective buyer or delegate bargaining to an intermediary. The intermediary is able to interrupt negotiating with the buyer to...
