We study the exclusionary properties of nonlinear price-quantity schedules in an Aghion-Bolton style model with elastic demand and product differentiation. We distinguish three regimes depending on whether and how the price of the incumbent good is linked to the quantity purchased from the rival...

We adapt the exclusion model of Choné and Linnemer (2014) to reflect the notion that dominant firms are unavoidable trading partners. In particular, we introduce the share of the buyer's demand that can be addressed by the rival as a new dimension of uncertainty. Nonlinear price-quantity...

This paper analyzes the effects of net neutrality regulation on investment incentives for Internet service providers (ISPs) and content providers (CPs), and their implications for social welfare. We show that the ISP's decision on the introduction of discrimination across content depends on a...

We provide a novel intuition for the observation that many brand manufacturers have restricted their retailers' ability to resell brand products online. Our approach builds on models of salience according to which price disparities across distribution channels guide a consumer's attention toward...

We provide an explanation for a frequently observed vertical restraint in ecommerce, namely that brand manufacturers partially or completely prohibit that retailers distribute their high-quality products over the internet. Our analysis is based on the assumption that a consumer's purchasing...

The analysis of horizontal mergers hinges on a tradeoff between unilateral effects and efficiency gains. The article examines the role of uncertainty (on the efficiency gains) in this tradeoff. Common wisdom is that the antitrust authorities should be very cautious about random gains. Our...

We study upstream horizontal mergers and their potential efficiency gains. We show that an upstream horizontal merger can give rise to two efficiency-enhancing effects when firms trade through two-part tariffs. It increases R&D investments and decreases wholesale prices when downstream...
