The sensitivity of U.S. aggregate investment to shocks is procyclical: the response upon impact increases by approximately 50% from the trough to the peak of the business cycle. This feature of the data follows naturally from a DSGE model with lumpy microeconomic capital adjustment. Beyond...

Microeconomic lumpiness matters for macroeconomics. According to our DSGE model, it explains roughly 60% of the smoothing in the investment response to aggregate shocks. The remaining 40% is explained by general equilibrium forces. The central role played by micro frictions for aggregate...

We investigate the time varying relation between hours and technology shocks using a structural business cycle model. We propose an RBC model with a Constant Elasticity of Substitution (CES) production function that allows for capital- and labor-augmenting technology shocks. We estimate the...

This paper shows that a modified real business cycle (RBC) model, one that includes home production and fiscal spending shocks, can solve one of the RBC puzzles and generates zero correlation between wages and hours. In addition, the micro-founded model presented here provides a sound...

We study the mechanics of transmission of fiscal shocks to labor markets. We characterize a set of robust implications following government consumption, investment and employment shocks in a RBC and a New-Keynesian model and use part of them to identify shocks in the data. In line with the...

This paper takes an otherwise standard real-business-cycle setup with government sector, and augments it with shocks to consumer confidence to study business cycle fluctuations. A surprise increase in consumer confidence generates higher utility, as the household values consumption more in...
