In the 1990s and early 2000s, a series of state and federal initiatives restructured electric markets. In many areas of the country generation was unbundled from transmission and distribution and competitive markets for energy generation were established. A decade has now passed since many of...

In this paper I describe a method for analyzing mergers in industries in which it is more cost effective to close capacity than to idle it. The method can be used to define markets, to assess the likelihood of competitive effects and to evaluate divestitures. I also discuss the method’s data...

The United States and other countries enforce their antidumping regulations in roughly the same way. There is a difference, however. The United States–but not other countries--now uses ‘zeroing’ in its determination of whether imports are dumped. The use of ‘zeroing’ will almost always...

Almost all countries have antidumping laws which regulate their imports. The United States and other countries enforce these laws within the terms of the World Trade Organization ("WTO"). There is a difference between U.S. enforcement and the enforcement approach of other countries, however. The...

Large, urban tertiary care hospitals often acquire outlying community hospitals. One possible motivation is to increase referrals. Sophisticated acquirers may even attempt to concentrate additional referrals among more profitable patients. We explore these issues by studying 26 vertical...

A “market” can be rigorously and precisely defined quantitatively, but the information to do so is typically not available. Instead, markets are often defined based on qualitative information, leading to the possibility of errors. I make some practical suggestions to mitigate such errors....

With the clamor rising over airport delays and with both the Congress and the Administration considering remedies, this paper advocates the use of market mechanisms, specifically slot auctions, to promote efficient usage of airport capacity, reduce airport delays, and, more generally, promote...

This paper analyses the dynamic aspects of knowledge sharing in R&D rivalry. In a model where research projects consist of N sequential stages, our goal is to explore how the innovators' incentives to share intermediate research outcomes change with progress and with their relative positions in...

Institutional characteristics of a typical residential real estate transaction may create a causal link between commission rate reductions and service degradation. Such a link mitigates agents’ incentive to compete on commission rates. Rebate bans, discriminatory MLS listing policies, and...

I formulate an econometric model of consumer learning and experimentation about new products in markets for packaged goods that nests alternative sources of dynamics. The model is estimated on household level scanner data of laundry detergent purchases, and the results suggest that consumers...
