In signaling environments ranging from consumption to education, high quality senders often shun the standard signals that should separate them from lower quality senders. We find that allowing for additional, noisy information on sender quality permits equilibria where medium types signal to...

In this article, we construct a two-period model to investigate what market conditions would support a credit card equilibrium given two commonly observed credit card pricing conventions consumers rarely are charged higher prices for using their credit cards and if they payoff their credit card...

We reconsider the employment effect of a minimum wage on employment in a symmetric model of monopsonistic competition, where each employer competes equally with every other employer. The employment effect depends on the degree of distortion in the labor market. If fixed costs are high (low), the...

In signaling environments ranging from consumption to education, high quality senders often shun the standard signals that should separate them from lower quality senders. We find that allowing for additional, noisy information on sender quality permits equilibria where medium types signal to...

When can you cheat some people without damaging your reputation among others? In a trust game between a firm and a series of individuals from two groups of different sizes, the firm has more incentive to cheat minority individuals because trade with the minority is less frequent and the...

We analyze models of product differentiation with perfect price discrimination and free entry. With a fixed number of firms, and in the absence of coordination failures, perfect price discrimination provides incentives for firms to choose product characteristics in a socially optimal way....
