This paper shows that generators exercised increasing market power in the England and Wales wholesale electricity market in the second half of the 1990s despite declining market concentration. It examines whether this was consistent with static, non-cooperative oligopoly models, which are widely...

This dissertation consists of three chapters relating to various topics in empirical Industrial Organization. The first two chapters deal with the empirical treatment of sales in online markets. The third chapter explores the level of pass-through for taxes on soft drinks. In the first chapter...

This dissertation consists of three chapters relating to dynamic demand models of storable goods and their application to taxes that are imposed on soft drinks. Broadly speaking, the first chapter builds the estimation strategy for dynamic demand models of storable goods that allows for...

This article shows that generators exercised considerable market power in the England and Wales wholesale electricity market in the late 1990s. This is surprising because static oligopoly models predict that falling market concentration should have reduced market power. The article tests the...

Regulating bidder participation in auctions can potentially increase efficiency compared to standard auction formats with free entry. We show that the relative performance of two such mechanisms, a standard first-price auction with free entry and an entry rights auction, depends...

The one-shot nature of most theoretical models of strategic investment, especially those based on asymmetric information, limits our ability to test whether they can fit the data. We develop a dynamic version of the classic Milgrom and Roberts (1982) model of limit pricing, where a monopolist...

"This paper examines the timing of commercial breaks by contemporary music radio stations. A simple model shows that stations may prefer, all else equal, to choose the same times (coordination) or different times (differentiation) for breaks depending on how listeners behave. It also shows that...

The ability of firms to reposition their products can determine the effects of demand shocks, mergers and policy interventions in differentiated product markets. This paper estimates a dynamic oligopoly model to measure repositioning costs in the commercial radio industry. Based on a set of...
