Macroeconomic Transmission of (Un-)Predictable Uncertainty Shocks

讲座内容简介：    

We document non-trivial predictability in the identified uncertainty shocks used in prominent studies of uncertainty’s macroeconomic transmission. The predictability stems not from the use of ex-post revised data rather than real-time data, but from failure to fully allow for uncertainty’s endogenousresponse to changes in economic conditions. We demonstrate two ways of purging uncertainty shocksof their predictable component and find that uncertainty’s transmission to output and employment issmaller than traditional estimates. We furthermore show that uncertainty’s relationship with aggregatereal activity is more the result of its role as an amplification mechanism for other macroeconomic and

financial shocks.
