T paper investigates the relationship between prices and market concentration in the auto rental industry. We assemble an original database that includes the number of auto rental operators and other exogenous demand and cost conditions at every commercial airport in the country. The data are interesting because we observe a large variation in market structure, ranging from more than 100 monopo...

This paper examines some of the economic and econometric issues that arise in attempting to measure the degree of concentration in an industry and its dynamic evolution.We o¤er new measures of concentration over aggregated periods of time and provide a sound statistical basis for inferences. Concentration is one aspect of the problem of measuring “market power” within an industry. Modern econom...

Hospitals have been merging with and acquiring nearby facilities, creating local and regional chains that potentially wield greater bargaining leverage than do stand-alone facilities.1 Concerns over the potential impact of health reform on hospital consolidation and pricing have been raised recently in Massachusetts and California, where hospital mergers and large hospital systems have been ass...

This paper studies the effect of market structure and macroeconomic uncertainty on the transmission of monetary policy. We motivate our analysis with a simple model which predicts that: 1) investment and production in more concentrated sectors are more affected by demand changes and 2) high uncertainty makes investment and production more sensitive to demand changes. The empirical analysis esti...

A long-held belief in industrial economics is that extending the size of the market reduces concentration and diminishes the ability of firms to exercise market power. At its simplest, this proposition stems from the idea that larger markets will be able to support a greater numbers of firms, and that the presence of more firms leads to more competitive pricing. This belief has had particular a...
