We study merger waves in vertically related industries where firms can engage in both vertical and horizontal mergers. Even though any individual merger would have been profitable, firms may refrain from merging for fear of negative impacts from other mergers. When they do merge, however, they...

Lump-sum quota bonuses are a specific type of quota bonus that provides a lump-sum transfer from a manufacturer to a retailer when the retailer's sales exceed a pre- determined quota. This paper explores whether lump-sum quota bonuses and two other vertical restraints, two-part tariffs and...

In a recent paper, Chiara Fumagalli and Massimo Motta (2006) challenge the idea that an incumbent can foreclose efficient entry in the face of scale economies by using exclusive contracts. They claim that inefficient exclusion does not arise when buyers are homogenous firms that compete...

A buyer group is a subset of downstream firms that pool their demand for an upstream input to negotiate a better deal with suppliers. This paper develops a simple model that shows how a buyer group changes market behavior, focusing on the impact on downstream firms outside the buyer group. This...

We study the effects of a vertical merger in a setting with a single upstream supplier of a critical input and two downstream customers which compete with each other. Initially, the upstream supplier first announces prices, then the two downstream customers announce their retail prices. We find...

We investigate the impact of vertical price restraints on the free-entry equilibrium and its welfare properties in a vertically related market where manufacturer-retailer hierarchies compete under asymmetric information. We compare the legal regimes of laissez-faire and ban on resale price...

We consider a vertically related industry and analyze how the total harm due to a price increase upstream is distributed over downstream firms and final consumers. For this purpose, we develop a general model without making specific assumptions regarding demand, costs, or the mode of...

Legal actions by direct and indirect purchasers to recover damages as a result of price-fixing by suppliers have been common in the United States for many years and are now beginning in a number of other countries including Australia and Canada. This paper argues that traditional measures of...

The existing literature on exclusive dealing is extended to take into account that buyers signing exclusive deals are typically competing firms that are differentiated from the perspective of their customers. We show, provided such downstream firms are not too differentiated, exclusive contracts...

Recent claims that online platforms have secured permanent monopolies, protected by barriers to entry from network effects and stockpiles of data, and should be the focus of intense antitrust and regulatory scrutiny, are inconsistent with the economics, technology, and history of online...
