We analyse the effect of learning by doing on firm performances when profit maximization follows a rule of thumb. Three regimes are compared: the technology sharing cartels, the oligopoly with spillovers, the proprietary regime. We show the dynamic implications on the industrial structure when...

This paper addresses the effects of multimarket contact on firms’ ability to collude. Real world imperfections tend to makes firms’ objective function strictly concave and market supergames ‘interdependent’: firms’ payoffs in each market depend on how they are doing in others. Then,...

This paper extends the standard model of bundling to allow products to be substitutes and for products to be supplied by separate sellers.  Whether integrated or separate, firms have an incentive to introduce a bundling discount when demand for the bundle is elastic relative to demand for...

A common sales tactic is for a seller to encourage a potential customer to make her purchase decision quickly, before she can investigate rival deals in the market.  We consider a market with sequential consumer search in which firms can achieve this either by making an exploding offer (which...

We show that when firms have incomplete information about the market demand and their costs, a (Bayesian) Cournot equilibrium in pure strategies may not exist, or be unique. In fact, we are able to construct surprisingly simple and robust examples of duopolies with these features. However, we...

In this paper, we examine how the structure of an imperfectly competitive input market affects final-good producers’ incentives to form a Research Joint Venture (RJV), in a differentiated duopoly where R&D investments exhibit spillovers. Although a RJV is always profitable, downstream firms’...

We examine how different unionisation structures and the spillovers of R&D activities affect R&D investments and firms’ incentives to form a Research Joint Venture. We find that whenever firms invest non-cooperatively, an industry union increases R&D investments, if industry specific...

We consider a multimarket framework where a set of firms compete on two interrelated oligopolistic markets. Prior to competing in these markets, firms can spy on others in order to increase the quality of their product. We characterize the equilibrium espionage networks and networks that...

We present a model of takeover where the target optimally sets its reserve price. Under relatively standard symmetry restrictions, we obtain a unique equilibrium. The probability of takeover is only a function of the number of .rms and of the insiders. share of total industry gains due to the...
