This is a survey of the economic principles that underlie antitrust law and how those principles relate to competition policy. We address four core subject areas: market power, collusion, mergers between competitors, and monopolization. In each area, we select the most relevant portions of...

This paper provides a new explanation for tying that is not based on any of the standard explanations -- efficiency, price discrimination, and exclusion. Our analysis shows how a monopolist sometimes has an incentive to tie a complementary good to its monopolized good in order to transfer...

This paper examines empirical issues of pricing and price dispersion within franchised restaurant and fast-food chains. Given the per se illegality of resale price maintenance (RPM) under current U.S. Antitrust laws, and the fact that franchised outlets are independent businesses under the law,...

In this paper, we provide a conceptual framework for understanding the phenomenon of exclusive dealing, and we explore the motivations for and effects of its use. For a broad class of models, we characterize the outcome of a contracting game in which manufacturers may employ exclusive dealing...

How far do the contractual implications of hold-up-based theories (Klein, Crawford, and Alchian (1978), Williamson (1979, 1985)) extend? I investigate this in the context of trucking. Quasi-rents in trucking are generally smaller than in the contexts studied in the previous empirical literature....

All-Units Discounts are vertical rebates in which a manufacturer pays a retailer a linear wholesale price up to a quantity threshold; beyond the threshold, the retailer receives a discount on all future and previous units. Such contracts, which are common in many industries, potentially have both...

An upstream manufacturer can use minimum retail price maintenance (RPM) to exclude potential competitors. RPM lets the incumbent manufacturer transfer profits to retailers. If entry is accommodated, upstream competition leads to fierce down- stream competition and the breakdown of RPM. Hence,...

The concept of a Nash equilibrium in Nash bargains, proposed in Horn and Wolinsky (1988), has become the workhorse bargaining model for predicting and estimating the division of surplus in applied analysis of bilateral oligopoly. This paper proposes a non-cooperative foundation for this...

We measure the pass-through of emissions costs to electricity prices and explore its determinants. We perform both reduced-form and structural estimations based on optimal bidding in this market. Using rich micro-level data, we estimate the channels affecting pass-through in a flexible manner,...

Search frictions can explain why the "law of one price" fails in retail markets and why even firms selling commodity products have pricing power. In online commerce, physical search costs are low, yet price dispersion is common. We use browsing data from eBay to estimate a model of consumer...
