It is increasingly observable that competitors in different industries share customer data, which can be used for targeted pricing. We propose a modified Hotelling model with two-dimensional consumer heterogeneity to analyze the incentives for such sharing and its ensuing welfare effects. We...

In markets where product quality is important, more than one characteristic is usually necessary for producers to define product quality. Standard theory maintains that: (i) in a duopoly there will be a quality leader no matter whether the product can incorporate one or two vertical attributes;...

We consider a high-quality dominant firm facing a low-quality competitive fringe. We show that the dominant firm's quantity is (weakly) increasing in its quality if and only if its marginal cost (weakly) exceeds that of the fringe; otherwise it is strictly decreasing in quality. This result is...

Public and private entities around the world are trying to induce the provision of higher-quality health care by adopting institutional arrangements intended to promote competition among care providers. I selectively survey and supplement the literature to show that an increase in...

Motivated by the unprecedented availability of consumer information on the Internet, we characterize the winners and losers from potential privacy regulation in the context of four commonly-used oligopoly models: a linear city model, a circular city model, a vertical differentiation model, and a...

We analyze competition in product lines by multi-product oligopolists that have preferential access to a local market but can supply a rival's market by incurring distance costs. We show that the width and degree of overlap in the product lines is greater in large markets and when the products...

In this paper we examine how trade liberalization affects collusive stability in the context of multimarket interactions. The model we consider is a segmented-markets duopoly with differentiated goods in which price-setting firms pool their incentive constraints across markets to sustain their...

Efficiency defence and merger remedies are key components in most merger control regimes. Although in many jurisdictions both the provision of efficiency-related evidence and remedy offers are at the merging firms' discretion, most previous works have only analysed them separately. This paper is...

We empirically examine the effects of industry consortia on the coordination of innovation strategies of the members. Our analyses utilize membership data from 32 consortia in wireless telecommunication technology subfields from 2000 to 2005 and prior art citations in standard-essential patents....

This paper presents a model of patent licensing in a standard setting context when patented technologies are heterogeneous in multiple dimensions. The model allows us to assess a policy proposal put forth in the literature: that an incremental value pricing rule should define Fair, Reasonable,...
