We examine investment incentives and market power in an experimental market. We characterize market power as the strategic interdependence of subjects' investment decisions and output decisions. The market is designed so that investment and output decisions can be jointly characterized as...

Most scholars believe the Supreme Court dropped its per se rule against price-fixing in Appalachian Coals (1933), re-instituting that rule in Socony-Vacuum (1940), but that the rule ignored "reasonableness" until BMI (1979), and that Maricopa (1982) relied on Socony to step back from...

Opportunities for buyers to negotiate discounts can blunt competition in the initial posting of prices. It is always an equilibrium for identical suppliers to post price at the common marginal cost. If few buyers have opportunities to bargain, this equilibrium is unique. If many buyers have...

Since at least the 1930's economists have puzzled over how to delineate the boundaries of the firm. With the advent of antitrust legislation in 1890, courts have been pressed to consider what constitute conspiracies between corporate entities to restrain commerce. By the 1940's, courts started...

When buyers choose the order in which they bargain with suppliers of known characteristics, prices are determined jointly by bargaining power and competitive intensity (the outside option to bargain with rival suppliers). Bargaining power becomes less important to the outcome as competition...

This article explores the role of customers in informing competition authorities and courts about the likely effects of proposed mergers. It discusses when, and about what, customers are most likely to be valuable sources of information. It also discusses the potential limitations of customer...

Over the past several decades, there has emerged a rough consensus among professional antitrust practitioners, and within the law and economics community generally, that the "competition" referred to in our antitrust statutes is not to be interpreted simply as pre-merger rivalry among entities....

The voluminous literature on the U.S. antidumping laws has a curious lacuna. There is little in this literature about the effects of antidumping duties on the volume of subject imports. One reason this key question has not frequently been investigated is the lack of data. U.S. antidumping duties...

In an effort to produce interoperable products, firms frequently participate in Standard Setting Organizations (SSOs) to collaboratively set technical standards for products used by networks of consumers. Some SSO members say they suffer from a type of holdup: after they sink technology-specific...

The spread of competition laws in Latin America has been accompanied, as in Central and Eastern Europe, by warnings against over-enforcement, and in particular against enforcement of provisions against the "abuse of a dominant position" in a market that may discourage legitimate, pro-competitive...
