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...

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...

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...

In this paper we consider a market situation in which initially there is an unintegrated monopoly upstream that owns an essential facility and two downstream firms. Then the market is liberalized allowing upstream entry and vertical integration. The equilibrium entry mode--sharing the incumbent...

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...

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...

This paper analyzes the equilibrium outcomes in a network industry under different vertical market structures. In this industry, an upstream monopolist operates a network used as an input to produce horizontally differentiated final products that are imperfect substitutes. Three potential...

A kiskereskedelmi árrögzítés évtizedek óta vitatott kérdés a közgazdasági elméletben. Az Egyesült Államok legfelsőbb bíróságának közelmúltbeli döntése - megszüntetve az ilyen típusú árkorlátozások önmagában törvénytelennek ítélését - ismételten felhívta a...
