This paper studies the cyclical dynamics of Mortensen and Pissarides' (1994) model of job creation and destruction when workers' effort is not perfectly observable, as in Shapiro and Stiglitz (1984). An occasionally-binding no-shirking constraint truncates the real wage distribution from below,...

Artículo de revista ; This note discusses recent theoretical work analyzing the causes of financial instability, its consequences for the macroeconomy, and thus the potential role for macroprudential policy. After discussing how information asymmetries and strategic complementarities can cause...

Este documento ocasional resume los avances recientes en el análisis teórico de las causas de la inestabilidad fi nanciera, de sus consecuencias macroeconómicas, y sus implicaciones acerca del posible papel de la política macroprudencial. En primer lugar, se analiza cómo se propagan las...

This paper considers a dynamic matching model with imperfectly observable worker effort. In equilibrium, the wage distribution is truncated from below by a no-shirking condition. This downward wage rigidity induces the same type of inefficient churning and "contractual fragility" as in Ramey and...

In this paper, we show that a simple model of smoothly state-dependent pricing generates a distribution of price adjustments similar to that observed in microeconomic data, both for low and high inflation. Our setup is based on one fundamental assumption: price adjustment is more likely when it...
