We consider two-sided markets in which consumers and firms endogenously determine whether they single-home (patronize only one platform), or multi-home (join competing platforms). We find that the standard competitive bottleneck allocation in which all consumers single-home and all firms...

This article provides a simple account of the effect of quality competition on the extent of sequential entry accommodation for a differentiated oligopoly market characterized by locational differentiation. The model is solved with consumers seeking a “love for quality” surplus utility while...

This publication features conversations on antitrust law with Nobel Prize laureates in Economics and aims at understanding how useful their work could be to antitrust law. Given the rigor and importance of their body of work, antitrust scholars, lawyers, officials, and anyone who's interested in...

Patent licensing contracts commonly prohibit licensees from challenging the validity of the patents at the basis of the contract or penalize such challenges. A considerable debate has emerged as to whether courts should enforce these challenge clauses. We argue that this debate has not gone far...

Over the last decades quota violations have become a norm for OPEC countries. However, the academic literature on OPEC focuses more on its production behavior than on analyzing the quota allocation process or characterizing quota violation patterns. This paper covers a theoretical model with...

Prices rise like rockets but fall like feathers. This stylized fact of most markets is confirmed by many empirical studies. In this paper, I develop a model with competitive firms and rational partially informed consumers where the asymmetric response to costs by firms emerges naturally. In...

The theory of multiproduct pricing is well developed in stylized models, although a unified theory has yet to be developed. As such, empirical analyses are rarely guided by strong theoretical hypotheses and are therefore scarce. This paper analyzes the interactions of ticket, parking, and...

There is an extensive literature studying the welfare comparison of third-degree price discrimination vs. uniform pricing, typically under the assumption that all markets are served under uniform pricing. In this study, we allow market foreclosure and show that the welfare comparison of price...

The markets for audiovisual content are subject to dynamic change. Where once “traditional” (free-to-air, cable, satellite) television was dominating, i.e. linear audiovisual media services, markets display nowadays strong growth of different types of video-on-demand (VoD), i.e. nonlinear...

In order to fight collusive behaviors, the best scenario for competition authorities would be the possibility to analyze detailed information on firms' costs and prices, being the price-cost margin a robust indicator of market power. However, information on firms' costs is rarely available. In...
