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,...

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...

This paper considers a dynamic matching model with imperfectly observable worker effort as in Shapiro and Stiglitz (1994). In our economy the no-shirking condition endogenously imposes real wage rigidity on the matching market. This generates "contractual fragility" and inefficient separations...

Gali (1999) used a VAR with productivity and hours worked to argue that technology shocks are negatively correlated with labor and are unimportant for the business cycle. More recently, Beaudry and Portier (2003) studied a VAR in productivity and stock prices. Remarkably, they found that the...
