Patent thickets, layers of licenses a firm needs to be able to offer products that embody technologies owned by multiple firms, and licensing policies have drawn increasing scrutiny from policy makers. Patent thickets involve complementary products, which gives rise to double marginalization --...

Assuming a fixed-proportion downstream production technology, partial forward integration by an upstream monopolist may be observed whether the monopolist is advantaged or disadvantaged cost-wise relative to fringe firms in the downstream market. Integration need not induce cost predation and...

The present paper studies and compares different vertical integration structures on consumers and total surplus with licensing by mean of a fixed fee in two successive homogeneous-good Cournot duopolies where one of the firms in each market has a different cost-reducing innovation. The key...

Hypermarkets are large retail suppliers of general merchandise or grocery items that also sell gasoline, often at very low margins. Using panel data for 1998-2002, this paper estimates the impact of hypermarkets on average state-level retail gasoline prices. The empirical results suggest a...

We develop a partial equilibrium, perfectly competitive framework of a (potentially) vertically integrated industry. There are three types of firms: upstream firms that use primary factors to produce an intermediate; downstream firms that use primary factors and intermediates to produce a final...

This paper analyzes the impact of vertical integration on product quality. Contrary to previous findings, it is shown that integration decreases quality in many natural situations. In general, the direction of the quality change is governed by three effects that are isolated in the model. This...

We investigate the early development of English cotton spinning by analyzing about 700 bankruptcies and 1300 dissolutions of partnership reported in the London Gazette, 1770–1840. The data show two temporal cycles, peaking in the early to mid-1800s and in the later 1820s, near the ends of...

The paper explores incentives for strategic vertical separation of firms in a framework of a simple duopoly model. Each firm chooses either to be a retailer of its own good (vertical integration) or to sell its good through an independent exclusive retailer (vertical separation). In the latter...

Vertical integration of production processes at international level and the resulting fragmentation of the value chains increasingly question the relevance of traditional trade indicators. Intermediate productions are increasingly offshored within these global value chains, giving place to what...
