 Animal spirits as an engine of boom-busts and throttle of productivity growthJournal of Economic Dynamics and Control, 2015, vol. 57, issue C, 24-53 Abstract: The news-shock literature interprets empirical news-shock identifications as signals about future productivity. Under this view, changes in productivity cause changes in expectations. I investigate an alternative interpretation whereby changes in expectations cause changes in productivity. I present a model where firms adopt the technology of a deterministic frontier, and where self-fulfilling expectational-shocks unleash a frenzy of adoption through which firms increase productivity. Consistent with the news evidence, stock prices and aggregate activity boom, yet TFP increases with a lag. Simulations using i.i.d. expectational-shocks yield moments consistent with the data, and qualitatively capture both high-frequency boom-busts and lower-frequency fluctuations. Finally, estimating a Beaudry–Portier style VECM on the simulated model output to identify a “news shock” recovers impulse response functions largely consistent with the Beaudry and Portier (2006) results.
