Aggregate Implications of Lumpy Investment: New Evidence and a DSGE Model
NBER Working Paper No. 12336
The sensitivity of U.S. aggregate investment to shocks is procyclical: the initial response 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 explaining this specific time variation, our model and evidence provide a counterexample to the claim that microeconomic investment lumpiness is inconsequential for macroeconomic analysis.
