I study the incentives of Cournot duopolists to share their technologies with their competitor in markets where intellectual property rights are absent and imitation is costless. The trade-off between a signaling effect and an expropriation effect determines the technology-sharing incentives. In...

In this paper, we show that in order for third-degree price discrimination to increase total output, the demands of the strong markets should be, as conjectured by Robinson (1933), more concave than the demands of the weak markets. By making the distinction between adjusted concavity of the...

When granting credit, banks depend on reliable information about the creditworthiness and risk structure of potential borrowers. This information is typically gathered by national credit bureaus. Nationally established banks depend on information from credit bureaus more than ever, particularly...

This paper analyses the relation between competition and concentration in the banking sector. The empirical answer is given by testing a monopolistic competition model of bank branching behaviour on individual bank data at county level (départements and provinces) in France and Italy. We...

In this paper we modify a standard quality ladder model by assuming that R&D is driven by outsider firms and the winners of the race sell licenses over their patents, instead of entering directly the inter- mediate good sector. As a reward they get the aggregate profit of the industry. Moreover,...

We examine conditions under which a platform firm can exclude rivals by bundling a product that some on one side of the market regard as essential with its platform, and pursue implications for market performance. We show that the impact of an exclusive dealing contract between the upstream firm...

How a cost shock is passed through into final consumer prices may relate to nominal price stickiness and rigidities, the existence of non adjustable cost components, strategic mark-up adjustments, or other contract terms along the supply distribution chain. This paper presents a simple framework...

Is deregulation sufficient to grant free entry in local credit markets? Economic theory suggests at least two ways in which asymmetric information between incumbents and entrants can work as an endogenous barrier to entry. First, entrants� pool of applicants contains a larger share of...

The paper models the evolution of regional asymmetries, and the associated intra-distribution mobility, as the outcome of adoption decisions taken by firms at different locations. The following equilibria are characterised: Persistent asymmetry where nobody adopts, Leapfrogging where low-quality...
