This paper illustrates how, in local retail markets, a multiproduct retailer may gain buyer power when some consumers are one-stop shoppers (multi-product shop-pers). We consider a model where independent suppliers negotiate terms of trade with a large multiproduct retailer and a group of...

We explore how the incentives for exclusion, both in upstream and downstream vertical markets, are related to the bargaining position of suppliers and retailers. We consider a model with a dominant upstream manufacturer and a competitive fringe of producers of imperfect substitutes offering...

We consider a setting where an upstream producer and a competitive fringe of producers of a substitute product may sell their products to two differentiated downstream retailers. We investigate two different contracting games; one with seller power and a second game with buyer power. In each...

Often, we observe that some TV channels are distributed on several platforms, and by several distributors on the same platform, while others are distributed exclusively by one distributor. In this paper, we analyse a TV channelel's incentives for choosing exclusive distribution versus full...

We study a setting where the opportunism or commitment problem identifed by Hart and Tirole (1990) may arise. An upstream monopolist may sell its product to two differentiated downstream retailers. Contract unobservability induces the manufacturer and each retailer to free-ride on margins earned...

This paper investigates a retailer's decision to introduce a private label and asks how the retailer's access to a private label may affect the pricing of substitute national brands. We consider a model with two vertically differentiated national brand manufacturers that negotiate sequentially...

Conventional economic theory stipulates that output in Cournot competition is too low relative to that which is attained in perfect competition. We revisit this result in a General Cournot-competitive Equilibrium model with two industries that dier only in terms of productivity. We show that in...

The related phenomena of learning curve and network effects are quite common in oligopolistic markets. In this context the present paper discusses the incentives of a technological leader to share its exclusive technology with potential competitors. An alliance may be preferable because partner...

Aggregate shocks in demand such as the burst of the 2001 dot-com bubble affect firms’ behavior and, therefore, the market structure. This paper proposes a fully dynamic oligopoly model to evaluate the impact of aggregate demand shocks on entry and exit costs as well as on investment and labor...

We consider games where agents are embedded in a network of bilateral relationships and have multivariate strategy sets. Some components of their strategies correspond to individual activities, while the other strategic components are related to joint activities and interaction with the...
