This paper analyzes the welfare implications of buyer mergers, which are mergers between downstream firms from different markets. We focus on the interaction between the merger's effects on downstream efficiency and on buyer power in a setup where one manufacturer with a non-linear cost function...

Analyzing a sequential bargaining framework with one retailer and two suppliers of substitutable goods, we show that slotting fees may emerge as a result of a rent-shifting mechanism when consumer shopping costs are taken into account. If consumers economize on their shopping costs by bundling...

Considering a vertical structure with perfectly competitive upstream firms that deliver a homogenous good to a differentiated retail duopoly, we show that upstream fixed costs may help to monopolize the downstream market. We find that downstream prices increase in upstream firms' fixed costs...

Rey and Tirole [Handbook of Industrial Organization. Amsterdam: Elsevier (2005)] considered a model in which a monopolist sells to downstream firms using nonlinear contracts. They showed that banning price discrimination fully restores the supplier’s ability to leverage its monopoly power by...

In non-union models, there is an ambiguous relationship between collusion on the product market and the resulting impact on the labour market. We can derive some conclusions by assuming a dual labour market with qualified and unqualified workers taking into account the efficiency effect when...

During the last decades the face of retailing has changed as a result of an ongoing concentration process and the emergence of increasingly large-scale retail outlets. Retailers constitute, therefore, “strategic gatekeepers” to final consumer markets providing them with buyer power...

Avec les conflits successifs qui opposent producteurs et distributeurs, la grande distribution se trouve régulièrement placée au cœur des débats publics et accusée par les producteurs de facturer abusivement ses services. Deux évolutions importantes du secteur sont à retenir pour tenter...
