In their seminal article on multilateral vertical contracting, McAfee and Schwartz (1994) argue that nondiscrimination clauses may be ineffective in curbing opportunism and may thus have no bite. This begs the question why nondiscrimination clauses are commonly observed in intermediate-goods...

We study the effects of a vertical merger in a setting with a single upstream supplier of a critical input and two downstream customers which compete with each other. Initially, the upstream supplier first announces prices, then the two downstream customers announce their retail prices. We find...

Moresi and Salop (2013) have extended the “upward pricing pressure” approach used in analyzing horizontal mergers to the analysis of vertical mergers. They present test expressions called the vGUPPIu and vGUPPId to see if the upstream and downstream prices will rise as a result of the...

Vertical separation of generation from electricity retailing has often been required as a condition of electricity market liberalisation. A well-developed and liquid contracts market is similarly suggested as necessary to manage the resulting wholesale market risks, which risks are further...

We study the implications of different contractual forms in a market with an incumbent upstream monopolist and free downstream entry. We show that traditional conclusions regarding the desirability of linear contracts radically change when entry in the downstream market is endogenous rather than...

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...

An increasing number of horizontal agreements involve both competitors and their common suppliers (or retailers). As vertical agreements, indirect horizontal agreements can help reduce coordination failures, but they also have the capacity to dampen competition. The negative welfare effect of...

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 article revisits the opportunism problem faced by an upstream monopolist contracting with several retailers over secret agreements, when contracts are linear. We characterize the equilibrium under secret contracts and compare it to that under public contracts in a setting allowing for...

This paper provides an economic analysis of recent vertical and horizontal mergers in the U.S. industry for audiovisual media content, including the AT&T-Time Warner and the Disney-Fox mergers. Using a theory-driven approach, we examine economic effects of these types of mergers on market...
