In this paper, we re-examine the recent evidence that technology shocks do not produce business cycle patterns in the data. We first extend Gal¡'s (1999) work, which uses long-run restrictions to identify technology shocks, by examining whether the identified shocks can be plausibly interpreted...

Structural vector autoregressions give conflicting results on the effects of technology shocks on hours. The results depend crucially on the assumed data generating process for hours per capita. We show that the standard measure of hours per capita has significant low frequency movements that...

Structural vector autoregressions give conflicting results on the effects of technology shocks on hours. The results depend crucially on the assumed data generating process for hours per capita. We show that the standard measure of hours per capita and productivity have significant low-frequency...

This paper investigates the source of historical fluctuations in annual UK labor productivity and employment data extending back to the 19th century. Long-run identifying restrictions are used to decompose shocks into technology shocks and other shocks. The UK results show more sample stability...
