The purpose of this paper is to present an approach with regard to the dynamic process of the general equilibrium during the business cycle fluctuations following monetary and fiscal interventions, which, I think, could contribute to bridging the differences between the different schools of...

Using a German firm-level data set, this paper is the first to jointly study the cyclical properties of the cross-sections of firm-level real value added and Solow residual innovations, as well as capital and employment adjustment. We find two new business cycle facts: 1) The cross-sectional...

Is time-varying firm-level uncertainty a major cause or amplifier of the business cycle? This paper investigates this question in the context of a heterogeneous-firm RBC model with persistent firm-level productivity shocks and lumpy capital adjustment, where cyclical changes in uncertainty...

This paper develops and estimates a general equilibrium rational expectations model with search and multiple equilibria where aggregate shocks have a permanent effect on the unemployment rate. If agents' wealth decreases, the unemployment rate increases for a potentially indefinite period. This...

This paper studies a model that includes investment-specific technological shocks, a variable capacity utilization rate, and endogenous product entry subject to sunk product development costs. These factors constitute a powerful amplification mechanism as they interact with each other. The model...

Transactions of used durables are large and cyclical, but their interaction with purchases of new durables has been neglected in business-cycle studies. I fill in this gap by introducing a new business-cycle model of durables where households resell their goods to the second-hand market and the...
