The purpose of this paper is to identify conditions under which hedonic price indexes provide an exact measure of consumer welfare, so that the welfare effects of quality change can be inferred. Our results are quite positive in providing a rational for existing practices, though the conditions...

Productivity improvements within establishments (e.g., factories, mines, or retail stores) are an important source of aggregate productivity growth. Past research has documented that learning by doing-productivity improvements that occur in concert with production increases-is one source of such...

Are location-specific factors--such as the education and attitude of the local workforce, supplier networks, institutional infrastructure, and local "culture"--important for understanding persistent heterogeneities among firms? We address this question in the context of the automobile industry....

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 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...
