We study the relationship between market structure and innovation in the global automobile industry from 1982 to 2004 using the dynamic industry framework of Ericson and Pakes (1995). Firms optimally choose a continuous level of innovation in a strategic and forward-looking manner, while...

This paper examines the impact of bank regulations, market structure, and national institutions on bank net interest margins and overhead costs using data on over 1,400 banks across 72 countries while controlling for bank-specific characteristics. The data indicate that tighter regulations on...

Almost all of the large literature on international trade with imperfect competition assumes exogenous market structures. The purpose of this paper is to develop a simple model that generates alternative market structures as Nash equilibria for different parameterizations of the basic model....

This paper explores the causes and consequences of cross-country variation in mortgage market structure. It draws on insights from several fields: urban economics, asset pricing, behavioral finance, financial intermediation, and macroeconomics. It discusses lessons from the credit boom, the...

We estimate the impact of weather variation on agricultural output in Indonesia by examining the impact of local rainfall shocks on rice output at the district level. Our analysis makes use of local meteorological data on rainfall in combination with government administrative data on...

Why are higher quality niches seen as intrinsically more profitable in business circles? Why do high quality products sometimes have a low real price, while it is unusual to see low quality products with high real prices? Can markets have quality differentiation as well as quality bunching? In...

We examine the relationship between market structure and the persistence of U.S. dollar-based sectoral real exchange rates for fourteen OECD countries. Our empirical results based on disaggregated data suggest that differences in market structure significantly determine the rates at which...

We study the determinants of asset market fragmentation in a model with strategic investors that disagree about the value of an asset. Investors' choices determine the market structure. Fragmented markets are supported in equilibrium when disagreement between investors is low. In this case,...

This paper uses new data to reexamine trends in concentration in U.S. markets from 1994 to 2019. The paper's main contribution is to construct concentration measures that reflect narrowly defined consumption-based product markets, as would be defined in an antitrust setting, while accounting for...
