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 describe recent advances in the empirical analysis of insurance markets. This new research proposes ways to estimate individual demand for insurance and the relationship between prices and insurer costs in the presence of adverse and advantageous selection. We discuss how these models permit...

Markets with asymmetric information will often employ third-party certification labels to distinguish between higher and lower quality transactions, yet little is known about the effects of certification policies on the evolution of markets. How does the stringency in quality certification...

We incorporate a search-theoretic model of imperfect competition into an otherwise standard model of asymmetric information with unrestricted contracts. We develop a methodology that allows for a sharp analytical characterization of the unique equilibrium, and then use this characterization to...

The primary goal of our paper is to quantify the importance of imperfect competition in the U.S. construction industry by estimating the size of rents earned by American firms and workers. To obtain a comprehensive measure of the total rents and to understand its sources, we take into account...

This paper studies commodity taxation in a general model featuring imperfect competition and tax salience. We derive new formulas for the incidence and marginal excess burden of commodity taxation, and we estimate the necessary inputs to the formulas by combining Nielsen Retail Scanner data from...

An upstream manufacturer can use minimum retail price maintenance (RPM) to exclude potential competitors. RPM lets the incumbent manufacturer transfer profits to retailers. If entry is accommodated, upstream competition leads to fierce down- stream competition and the breakdown of RPM. Hence,...

When markets are imperfectly competitive, trade policies can alter the terms of trade, shift profits from one country to another, and moderate or exacerbate existing distortions that are associated with the presence of monopoly power. In light of the various ways in which trade policies may...
