The two central pricing rules contained in most antitrust 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 note investigates the effects of a large horizontal merger on the shape of the 1-to-12 h price menus offered by parking garages in Paris. The merger caused low-end prices to increase proportionally more than high-end prices. This results in larger discounts on longer hours and hence in more...

We investigate how costly acquisition and exchange of customer-specific information affects industry profit and consumer welfare. Consumers differ in their preferences for competing brands and in their switching costs between brands. Brand-producing firms use their acquired knowledge of...

In this paper we investigate the evolution of quality adjusted prices for servers motivated by two facts. First, the productivity acceleration in the US economy since the mid 1990s is closely linked to spread of information technology of which networked computing is a large component. Second,...

Recent literature in Industrial Organization has shown that the threat of entry limits the price setting power of dominant firms and stimulates the incumbents to increase innovations ---both leading to welfare improvements. On the other hand dominant firms as incumbents strive to build up entry...

I revisit the relation between aftermarket power and basic market competition. I consider an infinite period model with overlapping consumers: in each period, one consumer is born and joins one of the existing installed bases, then aftermarket payoffs are received by sellers and consumers, then...

Generators supplying electricity markets are subject to volatile input and output prices and uncertain fuel availability. We show that a price-taking generator will generate only when the output price exceeds its operational marginal cost by the value of the option to delay the use of stored...

We report a policy experiment that illustrates a potential problem of using historical pass-through rates as a means of predicting the competitive consequences of projected firm-specific cost savings in antitrust contexts, particularly in merger analysis. The effects of cost savings on welfare...

This paper analyzes the impact of changes in the competitive market structure on an industry's total factor productivity (TFP) growth. The impact of horizontal mergers on TFP growth is of particular interest. The number of proposed horizontal mergers among U.S. firms totaled 28,818 from 1996 to...

Travel time losses in the Netherlands are likely to get worse in the years ahead if capacity is not added to cope with the demand. This particularly creates problems for business travel, which is characterized by a high “value of time”. In the Netherlands, policy makers have a long-standing...
