This paper provides an economic analysis of recent vertical and horizontal mergers in the U.S. industry for audiovisual media content, including the AT&T-Time Warner and the Disney-Fox mergers. Using a theory-driven approach, we examine economic effects of these types of mergers on market...

Economic theory provides various explanations for vertical integration but transaction costs seem to be a major determinant of backward, forward and lateral integration. The paper studies integration trends in the newly emerging Bulgarian pharmaceutical sector, seeking transaction cost...

This study constructs a model of anticompetitive exclusive contracts in the presence of complementary inputs. A downstream firm transforms multiple complementary inputs into final products. When complementary input suppliers have market power, upstream competition within a given input market...

We study upstream horizontal mergers and their potential efficiency gains. We show that an upstream horizontal merger can give rise to two efficiency-enhancing effects when firms trade through two-part tariffs. It increases R&D investments and decreases wholesale prices when downstream...

This paper explores the concept of vertical restraints or restrictions. It includes references to the competition law regimes of the European Union (EU), United States (US), and the People's Republic of China, as well as the key case law. It is part of the Concurrences' Global Dictionary of...

We construct a two-period model of the supply chain's openness in a durable goods market by introducing two marketing modes: leasing and selling. Given a marketing mode, at the beginning of the first period, an incumbent supplier and the downstream monopolist choose one of the trading modes: (i)...

The importance of economics to the analysis and enforcement of competition policy and law has increased tremendously in the developed market economies in the past forty years. In younger and developing market economies, competition law itself has a history of twenty to twenty-five years at most...

We explore the supply chain problem of a downstream durable goods monopolist, who chooses one of the following trading modes: an exclusive supply chain with an incumbent supplier or an open supply chain, allowing the monopolist to trade with a new efficient entrant in the future. The predicted...

This paper constructs a model of anticompetitive exclusive dealing in the presence of multiple entrants. Unlike the single-entrant model in previous literature, an entrant competes not only with the incumbent to deal with buyers but also with other entrants. The competition among entrants then...

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...
