We examine, in the context of less developed countries, the R&D behaviour of igopolistic firms who compete over R&D, as well as output levels. We also assume that the firms can sell in either of the two markets - the domestic, or the foreign. We show that entry liberalization, despite increasing...

We examine a simple model of collusion under a single-object second-price auction. Under the appropriate parameter conditions, in particular as long as collusion is neither too easy, nor too difficult, we find that the optimal policy involves both an effective ceiling, as well as a reserve price.

This article characterizes the conditions under which holdout (i.e. bargaining inefficiency) may, or may not be significant in a two-sided, one-buyer-many-seller model with complementarity. Our central result is that the severity of holdout (i.e. inefficiency) is critically dependent on three...

We examine pollution-reducing R&D by a monopoly firm producing a dirty product. In a dynamic framework with hyperbolic discounting, we establish conditions under which the Porter hypothesis goes through, i.e. environmental regulation increases R&D, thus reducing pollution, as well as increasing...

This paper develops a theory of sequential lending in groups in micro-finance that centers on the notion of dynamic incentives, in particular the simple idea that default incentives should be relatively uniformly distributed across time. In a framework that allows project returns to accrue over...

We examine Bertrand competition with non-rigid capacity constraints, demonstrating that the set of pure strategy Nash equilibrium constitutes an interval. We then examine the properties of this set as (a) the number of firms becomes large and (b) the capacity cost increases.

This paper characterizes the conditions under which holdout (i.e. bargaining inefficiency) may, or may not be significant in a two-sided, one-buyer-many-seller model with complementarity. We address this problem in a very general setup with a bargaining protocol that is symmetric and allows for...

We consider group-lending with joint liability where the provision of loans is conditional on prior savings. In a dynamic model with moral hazard and endogenous group-formation, we examine the effect of such schemes on the allocation of loans between strongly and weakly empowered borrowers. We...

We examine a model of price competition with strictly convex costs where the firms simultaneously decide on both price and quantity, are free to supply less than the quantity demanded, and there is discrete pricing. If firms are symmetric then, for a large class of residual demand functions,...

Purpose – The purpose of this paper is to build a theory of joint venture formation and instability based on synergy and monitoring. Design/methodology/approach – This problem is formulated as a dynamic game and solved using the notion of subgame perfect Nash equilibrium. Findings – It was...
