The article examines a differentiated-products duopoly model where the firms make entry decisions to two markets and then choose prices. The effects of product differentiation and entry costs are analyzed in two games: with and without price discrimination between the markets. Allowing price...

This paper investigates the market equilibrium and welfare effects of two-part tariff competition. When consumers are uniformly distributed on a Hotelling line, equilibrium prices are equal to marginal costs if and only if the demand of the marginal consumer is equal to the average demand. Entry...

We introduce a flexible third-degree price discrimination framework by modeling the information firms possess about consumers' locations (preferences) on the Salop circle as a partition. Higher information quality is translated into a partition refinement. In the limit, we obtain the perfect...

We investigate the possibility for two vertically related firms to at least partially collude on the wholesale price over an infinite horizon to mitigate or eliminate the effects of double marginalisation, thereby avoiding contracts which might not be enforceable. We characterise alternative...

We study how vertical integration in a two-sided media market affects investments in premium content. We show that a content provider provides the premium content exclusively to a platform, regardless of what the vertical structure of the industry is. However, a vertically integrated content...

We investigate the effect of a vertical merger on downstream firms' ability to collude in a repeated game framework. We show that a vertical merger has two main effects. On the one hand, it increases the total collusive profits, increasing the stakes of collusion. On the other hand, it creates...

This paper studies the competitive effects of a variety of publicly observable nonlinear contracts and vertical restraints in bilateral duopoly. When suppliers offer menus of contracts and inputs are sufficiently differentiated, there exist equilibria in which both retailers purchase from both...

Alliances between competitors where an established firm provides access to its marketing and distribution channels are an important real-world phenomenon. We analyze a market where an established firm, firm A, produces a product of well-known quality, and a firm with an unknown brand, firm B,...

Loyalty discounts, offered to customers that meet purchase thresholds, can shift share from rival firms. In a differentiated product duopoly, only one firm employs a program that customers adopt in equilibrium. Whenever consumers strongly prefer the product of said firm, such discounts increase...
