As a general proposition, antitrust law is hostile to price discrimination. This hostility appears to derive from a comparison of perfect competition (with no price discrimination) to monopoly (with price discrimination). Importantly, economists have known for some time that some forms of price...

Competition authorities have several tools at their disposal in crafting a competition policy. Most prominent are litigation and merger review. A less-recognized but often effective tool, however, is "competition advocacy." Broadly, competition advocacy is using persuasion, rather than coercion,...

I examine online and offline prices for popular disposable contact lenses. Idiosyncratic features of this market make it likely that offline firms set prices on the assumption that most of their customers are unaware of online prices. Consistent with lower online search costs, offline prices are...

Theories of vertical restraints have shown that vertical practices have the potential to harm competition. Although (or because) they are based on more realistic market structures and account explicitly for strategic interactions among competitions, the predictions of these models are...

This article was prepared as part of a recent symposium celebrating the Ninetieth Anniversary of the founding of the Federal Trade Commission. In addition, Fall 2004 marks the Thirtieth Anniversary of a pivotal moment in the establishment of the modern advocacy program at the FTC, Chairman Lewis...

The FTC was early to recognize that the ease with which online firms could collect and share consumer information would make privacy a core consumer protection issue. The FTC skillfully has used case-by-case enforcement under its section 5 authority to address privacy concerns for nearly...

Privacy has begun to creep into antitrust discussions. In some ways, this should not be surprising. Some of the largest and most ubiquitous companies, like Google and Facebook, give away their services in return for consumer data. If information about ourselves really is the price we pay for...

In this Article we focus upon an area in which greater convergence of U.S. policy with the practice of many foreign countries is long overdue: the treatment of public policies that suppress competition. Whereas the European Union (“EU”) and numerous other jurisdictions have taken strong...

This Chapter discusses the theories behind the call to incorporate privacy into antitrust and identifies some potential legal and economic hurdles to their application. Chief among them are (1) the extent to which privacy is an important dimension of competition; (2) identifying the underlying...

The legality of nonprice vertical practices in the U.S. is determined by their likely competitive effects. An optimal enforcement rule combines evidence with theory to update prior beliefs, and specifies a decision that minimizes the expected loss. Because the welfare effects of vertical...
