This paper analyses a model of vertical product differentiation with one incumbent and one entrant firm. It is shown that if firms can produce only one quality level welfare in this entry game can be lower than in monopoly. This is the case if qualities are strategic complements because the...

This paper introduces a novel method for examining the effects of vertical integration. The basic idea is to estimate the parameters of a vertical entry game. By carefully specifying firms' payoff equations and constructing appropriate tests, it is possible to use estimates on rival profit...

This paper investigates the pricing and vertical organization of differentiated products under imperfect competition. In a multiproduct context, a Cournot model is used to examine how substitution/complementarity relationships among products and vertical structures can affect the exercise of...

We examine vertical backward integration in a reducedform model of successive oligopolies. Our key findings are: (i) There may be asymmetric equilibria where some firms integrate and others remain separated, even if firms are symmetric initially; (ii) Efficient firms are more likely to integrate...

In this paper we will examine the issue of ownership unbundling and forced divestiture remedies imposed in a series of recent competition law cases of the energy market - examined in other papers - in relation to the possible existence of a series of legal obstacles. These energy market...

This paper presents an overview of what economists can say about vertical constraints by multi-sided platforms at this stage in the development of our knowledge about the economics of these businesses. It describes the general procompetitive and anticompetitive uses of vertical restraints by...

The idea that tech companies should be permitted to acquire nascent start-ups is under attack from antitrust populists. Yet, this debate on vertical mergers has overlooked important empirical contributions regarding innovation-related mergers in the strategy literature. This Article explores the...

We investigate a vertically integrated theater's contract and screen allocation decisions in a movie industry characterized by demand uncertainty, price uniformity, and revenue-sharing contracts. Based on a simple theoretical model that describes the decisions of theaters and movie distributors,...

The paper tackles the discussion about vertical separation in the electronic communications sector, in its two main forms functional and structural. The author will argue how mandatory structural separation under certain conditions could be a possible option. The evidence is provided by the...

We study how vertical integration in a two-sided media market affects investments in premium content. We show that a content provider provides the premium content exclusively to a platform, regardless of what the vertical structure of the industry is. However, a vertically integrated content...
