We develop a two-country model of endogenous innovation and imitation in order to study the interactions between these two processes. Firms in the North race to bring out the next generation of a set of technology-intensive products. Each product potentially can be improved a countably infinite...

Quality certification is a common tool to reduce asymmetric information and enhance trust in marketplaces. Should the certificate focus on seller inputs such as fast shipping, or include output measures such as consumer ratings? In theory, incorporating output measures makes the certificate more...

This essay reviews the theoretical and empirical literature on quality disclosure and certification. After comparing quality disclosure with other quality assurance mechanisms and describing a brief history of quality disclosure, we address three key theoretical issues: (i) Why don't sellers...

We investigate empirically the determinants of the quality of governments in a large cross-section of countries. We assess government performance using measures of government intervention, public sector efficiency, public good provision, size of government, and political freedom. We find that...

We develop a new model of quality to capture the idea that even if a customer chooses to purchase a product, it may fail to deliver.' In this event, the customer may wish to choose some other product. We model this as a two stage game where firms first choose quality and then price. We find that...

We study the relation between product quality and worker quality using an economic model that, under certain conditions, provides a direct link between product price, product quality and work force quality. Our measures of product quality are the evolution in the detailed product price relative...

We estimate an insurer-specific preference function which rationalizes hospital referrals for privately-insured births in California. The function is additively separable in: a hospital price paid by the insurer, the distance traveled, and plan and severity-specific hospital fixed effects...

The theory of cost-shifting posits that nonprofit hospitals respond to negative financial shocks by raising prices for privately insured patients. We examine how hospitals responded to the sharp reductions in their endowments caused by the 2008 stock market collapse. We find that the average...

What is the impact and value of hurricane forecasts? We study this question using newly-collected forecast data for major US hurricanes since 2005. We find higher wind speed forecasts increase pre-landfall protective spending, but erroneous under-forecasts increase post-landfall damage and...

We examine the extent that product differentiation affects the duration of US import trade relationships. Applying nonparametric and semiparametric techniques to highly disaggregated product-level data we estimate that the hazard rate is at least 18 percent higher for homogenous goods than for...
