Based on my recent work with several co-authors this paper explores the relationship between discretion, reputation, competition and entry in procurement markets. I focus especially on public procurement, which is highly regulated for accountability and trade reasons. In Europe regulation...

This paper analyzes a simple vertical product differentiation model with demand uncertainty and derives a risk neutral monopolist's optimal market entry timing, her optimal pricing and optimal quality choice by incorporating Knightian uncertainty, irreversibility, and flexibility in...

Two firms produce a good with a horizontal and a vertical characteristic called quality. The difference in the unobservable quality levels determines how the firms share the market. We consider two scenarios: In the first one, firms disclose quality; in the second one, they send costly signals...

We embed signaling in the classical Cournot model in which several firms sell a homogeneous good. The quality is known to all the firms, but only to some buyers. The quantity-setting firms can manipulate the price to signal quality. Because there is only one price in a market for a homogeneous...

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 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,...

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...

Direct-to-consumer drug advertising has recently become an important and controversial component of drug marketing. In this paper we examine one of the claimed benefits of drug advertising: encouraging the undiagnosed to seek out medical treatment. We measure how advertising affects an...

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...
