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...

In this paper we investigate the effects of uncertainty shocks on economic activity using a Dynamic Stochastic General Equilibrium (DSGE) model with heterogenous agents and a stylized banking sector. We show that frictions in credit supply amplify the effects of uncertainty shocks on economic...

Can increased uncertainty about the future cause a contraction in output and its components? An identified uncertainty shock in the data causes significant declines in output, consumption, investment, and hours worked. Standard general-equilibrium models with flexible prices cannot reproduce...

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 co-movements among key macro variables. With countercyclical markups...

de Groot, Richter, and Throckmorton (2018) argue that the model in Basu and Bundick (2017) can match the empirical evidence only because the model assumes an asymptote in the economy's response to an uncertainty shock. In this Reply, we provide new results showing that our model's ability to...

This survey features three parts. The first one covers the recent literature on domestic (i.e., country-specific) uncertainty and offers ten main takeaways. The second part reviews contributions on the fast-growing strand of the literature focusing on the macroeconomic effects of uncertainty...

What are the effects of beliefs, sentiment, and uncertainty, over the business cycle? To answer this question, we develop a behavioral New Keynesian macroeconomic model, in which we relax the assumption of rational expectations. Agents are, instead, boundedly rational: they have a...
