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 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 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 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...

It is well known that the profitability of horizontal mergers with quantity competition is scarce. However, in an asymmetric Stackelberg market we obtain that some mergers are profitable. Our main result is that mergers among followers become profitable when the followers are inefficient enough....

In this paper, we endogenize the decision of a research laboratory that owns a patented process innovation on whether to remain independent as an external patentee or to merge with a manufacturing firm, becoming an internal to the industry patentee. We show that a merger is profitable only for...

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...

In this paper, we suggest a method to test price-fixing agreements. Prices fixed to multiple shipments are decomposed into a set of destination market effects and time effects in order to allow us to perform an analysis of residuals. We examine the pricing behavior of vitamin C in the European...
