We test for causality between inflation and its associated uncertainty by means of both in-sample and out-of-sample modelling. Our findings indicate that the impact of inflation on inflation uncertainty is more pronounced than the reverse causal effect.

This study provides cross country robust evidence on interdependencies among inflation, output growth and respective uncertainties for the current era of low inflation policies. We attribute the extant empirical disagreement on these relations to the fact that long sampling periods and single...
