This paper examines the role of uncertainty shocks in a one-sector, representative-agent dynamic stochastic general-equilibrium model. When prices are flexible, uncertainty shocks are not capable of producing business-cycle comovements among key macro variables. With countercyclical markups...

We examine the macroeconomic and term-premia implications of monetary policy uncertainty shocks. Using Eurodollar options, we employ the VIX methodology to measure implied volatility about future short-term interest rates at various horizons. We identify monetary policy uncertainty shocks using...

At the zero lower bound, the central bank's inability to offset shocks endogenously generates volatility. In this setting, an increase in uncertainty about future shocks causes significant contractions in the economy and may lead to non-existence of an equilibrium. The form of the monetary...
