We examine the impact of the licensing policies of one or more upstream owners of essential intellectual property (IP hereafter) on the variety offered by a downstream industry, as well as on consumers and social welfare. When an upstream IP monopoly increases the number of licenses, it enhances...

We analyze a successive vertical Cournot oligopoly model with homogeneous intermediate and final goods. Under restricted entry in both upstream and downstream markets, the input price continuously falls on a sequential merger path. Partial input foreclosure never occurs. However, when there is...

In this paper, we discuss the case of the integration between NSK and Amatsuji Steel Ball by using the successive oligopoly model. We show that the integration does not lead to input foreclosure. However, it leads to customer foreclosure, if the fixed cost of a rival firm in the upstream market...

A margin squeeze occurs when a vertically integrated company, dominant in the supply of an indispensable upstream input, pursues a pricing policy which prevents downstream competitors from trading profitably, thereby leading to their ultimate exclusion from the downstream market.In the...

We develop a model of vertical mergers with open auctions upstream. This setting may be appropriate for industries where inputs are procured via auction-like “requests for proposal.” For example, Drennan et al (2020) reports that a model of this type was used during the CVS-Aetna merger...

This article offers the following recommendations, focusing on #3 and 6:1. Specifics on how the Agencies will implement the principles set forth in the Guidelines. The Guidelines state throughout that the Agencies “may consider” certain factors; this language should be revised to say...

The idea that tech companies should be permitted to acquire nascent start-ups is under attack from antitrust populists. Yet, this debate on vertical mergers has overlooked important empirical contributions regarding innovation-related mergers in the strategy literature. This Article explores the...

We examine the role of private information on the impact of vertical mergers. A vertical merger can improve the information that is available to an upstream monopolist because, after the merger, the monopolist can observe the cost of its downstream merger partner. In the pre-merger world,...

Platforms acting as sales channels for producers often charge users for access, via a subscription fee or a markup on hardware. We compare two common forms of vertical pricing agreement that platforms use with sellers: per-­unit and proportional fees. In particular, we analyze the critical role...

Using data on the prices paid by multichannel video programing distributors (“MVPDs”) for basic cable networks, I conduct a retrospective analysis of the price effects of the Comcast-NBCU merger. Estimates from both the difference-in-differences and lagged-dependent variable models indicate...
