Investment-Specific News Shocks and U.S. Business Cycles
This paper provides robust evidence that news shocks about future investment- specific technology (IST) constitute a significant force behind U.S. business cycles. Using a recent empirical approach to identifying news shocks, we find that positive IST news shocks induce comovement, i.e., raise output, consumption, investment, and hours. These shocks account for 70% of the business cycle variation in output, hours, and consumption, and 60% of the variation in investment, and have played an important role in nine of the last ten U.S recessions. IST news shocks also dominate unanticipated IST shocks in accounting for the forecast variance of aggregate variables. The findings have two important implications for research on news driven business cycles. First, they provide strong support for shifting focus to IST news shocks when investigating the role of news (or foresight) in driving business cycles. Second, an important avenue for further research is to consider structural mechanisms that can enhance the role of IST news shocks in estimated dynamic general equilibrium models.
