A business cycle model with nominal wage contracts and government
We incorporate nominal wage contracts and government into a quantitative general equilibrium framework. Thus, our model includes three types of shocks: a fiscal shock, a monetary shock, and a technology shock. We show that it is possible in this type of environment to generate a low correlation between hours worked and the return to working, a moderately negative correlation between output and aggregate prices and a moderately positive correlation between the real wage rate and output. In sharp contrast with RBC models with indivisible labor, wage contracts magnify mainly the effect of ...

Cyclical factor utilization
We introduce procyclical labor and capital utilization, as well as costs of rapidly increasing employment, into a business-cycle model. Plausible variations in factor utilization enable us to explain observed variability of real GNP with considerably smaller economy-wide disturbances. The costs of adjustment create very interesting and realistic lead and lag relationships: Employment does not peak until a full quarter after output; workweeks, effort, capital utilization, and productivity all sharply lead the business cycle.
