Sectoral TFP news shocks

摘要

We document a strong similarity in the macroeconomic effects of consumption-specific and investment specific TFP news shocks. This co-linearity suggests a diffusion channel of technological innovations from the investment to the consumption sector that forecast future changes in aggregate TFP. This finding connects two views of the literature on news shocks: aggregate TFP news and investment specific news. (C) 2018 Published by Elsevier B.V.
