We study the effects of changes in uncertainty about future fiscal policy on aggregate economic activity. Fiscal deficits and public debt have risen sharply in the wake of the financial crisis. While these developments make fiscal consolidation inevitable, there is considerable uncertainty about...

We embed a news shock, a noisy indicator of the future state, in a two-state Markov-switching growth model. Our framework, combined with parameter learning, features rich history-dependent uncertainty dynamics. We show that bad news that arrives during a prolonged economic boom can trigger a...

Recent empirical studies suggest that the negative effects of uncertainty shocks are stronger in recessions than during booms. In this study, I provide a theoretical mechanism that can explain this empirical observation. I start from the argument that the effect of uncertainty on investment...
