The central claim of this Article is that, as a descriptive matter, trademark legislation and court interpretation is a close normative match with the Chicago School approach of scholars such as Robert Bork and Richard Posner. The organizing intellectual structure of modern trademark law, as...

Does significant market power or the presence of large rents affect optimal income taxation, calling for greater redistribution due to tainted gains? Or perhaps less because of an additional wedge that distorts labor effort? Do concerns about inequality have implications for antitrust,...

In markets with significant scale economies and network effects, scholars and policymakers often tout open access and interoperability requirements as superior to both regulated monopoly and the break-up of dominant firms. In theory, by compelling firms to coordinate to develop common...

We provide a canonical and tractable model of a trade platform enabling buyers and sellers to transact. The platform charges a percentage fee on third-party product sales and decides whether to be "hybrid", like Amazon, by selling its own product. It thereby controls the number of differentiated...

The paper first summarizes the benefits of competition, i.e. why competitive markets are more efficient than oligopolistic or monopolistic markets, and the threats to competitive markets from cartels, concentration, and government interference. In the main part, the paper presents the key...
