The result of neutrality of vertical integration for competition postulated by the Chicago School can be supported by a benchmark model with (1) an upstream monopolist, (2) homogeneous goods downstream and (3) observable (two-part tariff) contracts. The result does not hold however, whenever any...

We consider the role of the endogenous choice of platform quality in a broadcasting duopoly market where competing media platforms choose also their level of advertising. We compare the equilibrium levels of quality, advertising and welfare under private and mixed duopoly competition. We show...

We build a framework linking competition in the media market to political participation. Media outlets report on the ability of candidates running for office and compete for audience through their choice of slant. Citizens consume news only if the expected utility of being informed about...

We consider the role of a publicly-owned platform and program quality in the free to air broadcasting industry. We compare the equilibrium levels of advertising under private and mixed duopoly competition, and show that the connection between program quality and advertising incentives are...

Anecdotal evidence and recent empirical work suggest that musicpiracy has differential effects on artists depending on their popularity.Existing theoretical literature cannot explain such differential effectssince it is exclusively concerned with single-firm models. We present amodel with two...

We analyze third degree price discrimination by an upstream monopolistto a continuum of heterogeneous downstream firms. The novelty of ourapproach is to recognize that customizing prices may be costly, whichintroduces an interesting trade-off. As a consequence, partial pricediscrimination arises...

The paper studies a Partial Cartel model where only a subset of firms colludes. In this model, firms' ability to collude depends on the discount factor. In addition, as hardly any attention has been given by the literature to the case where mergers take place in a collusive framework, the...

A monopolist retailer facing two suppliers producing two symmetric and independent goods improves its bargaining position by commiting to sell only one good. We analyze if this advantage extends to the case where there are two undierentiated retailers competing in the same market. With linear...

We consider two (symmetric) upstream firms producing independent goods that sell to consumers through symmetric retailers. The distinguishing feature of retailers is that they have a selling capacity, in the sense, that there is an upper limit in the total units of the two goods they can sell....

This paper analyzes how the existence of upstream market power affects endogenous quality choice in a setting where two downstream firms are locked in a bilateral monopoly with their own input suppliers. The main result is that the degree of product differentiation is reduced as upstream market...
