We study dynamic price adjustment under imperfect competition when consumers have non-time-separable preferences. In our model an intertemporal link arises in the consumers' maximization problems because current price and firms must take this into account when making their decisions. The main...

In sender-receiver games high-quality types can distinguish themselves from low-quality types by sending a costly signal. Allowing for additional, noisy information on sender types can radically alter sender behavior in such games. We examine equilibria where medium types separate themselves...

A number of theories (search and efficiency wages) have been developed, in part, to explain why identically able workers are often paid different wages. However, when there is a minimum wage, they do not explain the resulting "spike" in the wage distribution. Our model's predictions are...
