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 model the relationship between local agricultural surpluses, nutritional status, and height, and we test the hypothesis that adult height is positively correlated with the local production of nutrition in infancy. We test the hypothesis on two samples of Union Army recruits - one consisting...

This paper estimates the impact on consumer behavior of a firm’s voluntary disclosure of information. Specifically, we study the impact of Starbucks’ disclosure of calorie information on its menu boards in June 2013. Using data on over 250,000 consumers’ visits to specific restaurant...

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 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...

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...
