On The Role of Technology Shocks as a Source of Business Cycles: Some New Evidence

I provide some new evidence that reinforces the conclusion in Galí (1999) that exogenous variations in technology play a very limited role, if any, as sources of the business cycle. First, I provide evidence that supports the identification of technology shocks proposed in that paper. Second, I show that similar findings obtain when the same approach is implemented for the Euro area, using a newly available data set.
