The two central pricing rules contained in most antirust laws are prohibitions of below-cost pricing and prohibitions of discriminatory pricing. This article shows that the rule against discriminatory pricing may actually induce firms to charge exclusionary below-cost prices, even in the...

This paper studies differential pricing by an upstream monopolist whose cost to supply the intermediate good differs across buyers in the downstream. It is shown that, different from third degree price discrimination based on the downstream firms' cost of transforming the intermediate good into...

This paper examines the effect of private label sold by one of two retailers (the “chain store”) on wholesale prices in the intermediate goods market. Under sym- metric retail costs, the chain store can make the wholesale price lower than its rival (the “local store”) when the private...

Price markups over marginal cost are often higher on "aftermarket" parts and services for durable goods than they are on the goods themselves. A popular explanation is that the aftermarket good is used as a "metering" device. This paper explores what happens in the metering model as foremarket...

In the context of an infinitely repeated capacity-constrained price game, we endogenize the composition of a cartel when firms are heterogeneous in their capacities. When firms are sufficiently patient, there exists a stable cartel involving the largest firms. A firm with sufficiently small...

Many high technology goods are based on standards that require several essential patents owned by different IP holders. This gives rise to a complements and a double mark-up problem. We compare the welfare effects of two different business strategies dealing with these problems. Vertical...

In its landmark ruling in Illinois Brick Co. v. Illinois in 1977, the U.S. Supreme Court restricted standing to sue for recovery of antitrust damages to direct purchasers. However, antitrust damages are typically (in part) passed on to intermediaries lower in the chain of production and...

The conventional wisdom is that the formation of patent pools is welfare enhancing when patents are complementary, since the pool avoids a double-marginalization problem associated with independent licensing. This conventional wisdom relies on the effects that pooling has on downstream prices....

After describing the essential features of the book market, a welfare analysis of the fixed book price agreement is given. Allowance is made for the opportunity cost of reading. Theoretically, the agreement pushes up book prices and depresses book sales. However, more titles will be published,...

Empirical evidence suggests that many mergers do not increase profits of the participating firms and decrease welfare. Due to the globalization of markets we should take an international view on mergers and their welfare effects. This paper develops a Bertrand-model of an international...
