The merger of Fleet and BankBoston in September 1999 resulted in a regional New England lending market in which only one large, universal bank remained. We explore the extent to which that merger resulted in monopoly rents for the combined entity in some niches within the regional loan market....

We study intertemporal price discrimination when consumers can store for future consumption needs. To make the problem tractable we offer a simple model of demand dynamics, which we estimate using market level data. Optimal pricing involves temporary price reductions that enable sellers to...

Consumer auctions were very popular in the early days of internet commerce, but today online sellers mostly use posted prices. Data from eBay shows that compositional shifts in the items being sold, or the sellers offering these items, cannot account for this evolution. Instead, the returns to...

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...

We develop a theoretical framework to characterize strategic behavior in sequential markets under imperfect competition and limited arbitrage. Our theory predicts that these two elements can generate a systematic price premium. We test the model predictions using micro-data from the Iberian...

We estimate the economic surplus created by Medicare Advantage under its reformed competitive bidding rules. We use data on the universe of Medicare beneficiaries, and develop a model of plan bidding that accounts for both market power and risk selection. We find that private plans have costs...

The concept of a Nash equilibrium in Nash bargains, proposed in Horn and Wolinsky (1988), has become the workhorse bargaining model for predicting and estimating the division of surplus in applied analysis of bilateral oligopoly. This paper proposes a non-cooperative foundation for this...

We document a strong correlation in the brand of automobile chosen by parents and their adult children, using data from the Panel Study of Income Dynamics. This correlation could represent transmission of brand preferences across generations, or it could result from correlation in family...

The audit market's unique combination of features-its role in capital market transparency, mandated demand, and concentrated supply-means it receives considerable attention from policymakers. We explore the effects of two market scenarios that have been the focus of policy discussions: a)...

We present a model of market competition and product differentiation in which consumers' attention is drawn to the products' most salient attributes. Firms compete for consumer attention via their choices of quality and price. With salience, strategic positioning of each product affects how all...
