Uncertainty shocks in currency unions
Uncertainty shocks cause economic activity to contract and more so, if an effective lower bound on interest rates constrains monetary policy. In this paper, we investigate whether countries within currency unions are also particularly prone to suffer from the adverse effects of heightened uncertainty because they lack monetary independence. First, we estimate a Bayesian VAR on quarterly panel data for 16 Euro Area countries. We find that country-specific uncertainty shocks impact economic activity adversely. Second, we calibrate a DSGE model of a small open economy and show that it can account for the evidence. Finally, we show that currency union membership strongly reduces the effects of uncertainty shocks because it anchors long-run expectations of the price level and thus alleviates precautionary price setting in the face of increased uncertainty.
