• Resumen

  • This study investigates the validity of technology shocks as a driving force of US business cycle fluctuations. Using three well-known structural vector autoregression ( SVAR) models, we analyse how structural shocks are associated with the variations of output and hours worked at business cycle frequencies. Empirical results reveal that technology shocks remain an important source of cyclical movements in output. Furthermore, a positive technology shock does not lead to a decline in hours worked, in contrast to previous studies. Our SVAR-based evidence does not support discarding a technology-shock-driven business cycle theory.
