There are significant differences in the dynamics of employment over the business cycle between young and old manufacturing plants. Young plants are more sensitive to aggregate disturbances, and they respond to them along different margins. We interpret these differences as reflecting greater...

The authors describe how evidence on aggregate job flows challenges standard business cycle theory and discuss recent developments in business cycle theory aimed at accounting for the evidence.

This paper investigates the response of real wages and hours worked to an exogenous shock in fiscal policy. We identify this shock with the dynamic response of government purchases and tax rates to an exogenous increase in military purchases. The fiscal shocks that we isolate are characterized...

Household investment, that is investment in consumer durables and housing, leads non-residential fixed investment over the U.S. business cycle. This observation represents a potent challenge to real business cycle (RBC) theory. First of all the theory has been unable to account for it. In...

We introduce two modifications into the standard real business cycles model: habit persistence preferences and limitations on intersectoral mobility. The resulting model is consistent with the observed mean equity premium, mean risk free rate and Sharpe ration on equity. With respect to the...

We study the aggregate implications of (S,s) inventory policies in a dynamic general equilibrium model with aggregate uncertainty. Firms in the model's retail sector face idiosyncratic demand risk, and (S,s) inventory policies are optimal because of fixed order costs. The distribution of...

Evidence on the cost of business equipment investment supports a new way of understanding growth and business cycles. The equipment price has been falling for most of the last 40 years and it tends to fall more the faster economy is growing. This suggests that technological change embodied in...

The marginal cost of plant capacity, measured by the price of equity, is significantly procyclical. Yet, the price of a major intermediate input into expanding plant capacity, investment goods, is countercyclical. The ratio of these prices is Tobin's q. Following convention, we interpret the...
