Uncertainty shocks in a model of effective demand
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 comovement. However, uncertainty shocks can easily generate comovement with countercyclical markups through sticky prices. Monetary policy plays a key role in offsetting the negative impact of uncertainty shocks during normal times. Higher uncertainty has even more negative effects if monetary ...

Uncertainty Shocks in a Model of Effective Demand: Reply
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 match the data does not rely either on assuming preferences that imply an asymptote nor on a particular value of the intertemporal elasticity of substitution. We demonstrate that shifting to preferences that are not vulnerable to the Comment?s critique does not change our previous conclusions about the ...
