Antitrust authorities consider commodity bundling as an extension of monopoly power to other markets which harms consumers. This paper analyzes quality competition and its effect on consumer surplus for the case of commodity bundling by a multi-product firm in a vertically differentiated...

In this paper we investigate the pricing incentives of IP holders and compare the equilibrium royalty rates charged by vertically integrated IP holders with those of non- integrated IP holders. We show that under many circumstances non-integrated companies are likely to charge lower royalties...

I this paper we consider a market situation in which initially there is an unintegrated monopoly upstream entry and vertical integration. The equilibrium entry mode -sharing the incumbent facility or building a new facility- is derived as well as the equilibrium market structure. Several policy...

We analyze the competitive effects of backward vertical integration in a model with oligopolistic firms that exert market power upstream and downstream. In contrast to previous literature, we show that a small degree of vertical integration is always procompetitive because efficiency effects...

This chapter estimates sustainable coverage and competitive effects of entry for Swiss newspaper sellers which sell composite goods, including a range of other products such as food and near-food items. It utilises the applied entry threshold ratio methodology from Bresnahan and Reiss (1991),...

While vertical integration is traditionally seen as a solution to the hold-up problem, this paper highlights instead that it can generate hold-up problems — for rivals. We first consider a successive duopoly where competition among suppliers eliminates any risk of hold-up; downstreamfirms thus...

We investigate the upstream and downstream product-market effects of a large sample of horizontal mergers and acquisitions from 1980-1997. We construct a dataset that identifies the corporate customers, suppliers, and rivals of the firms initiating horizontal mergers and use this dataset to...

In September 2005, the Chilean Competition Authority filed a complaint against the 5 largest private health insurance providers for violation of antitrust laws. The 5 providers were accused of colluding to reduce the coverage of the plans offered to customers between March 2002 and March 2003....

This paper models a sequential merger formation game with endogenous efficiency gains in which every merger has to be submitted for approval to the Antitrust Authority (AA). Two different types of AA are studied: first a myopic AA, which judges a given merger without considering that subsequent...
