This paper examines the effects of expansionary technology shocks (shocks that increase labor productivity and factor … inputs) as opposed to contractionary technology shocks (shocks that increase labor productivity, but decrease factor inputs … productivity and production inputs. In addition, these shocks trigger different reactions of certain variables, which can help …
