Abstract

We asses the general robustness of previous findings claiming that policy uncertainty exerts non-trivial influences on the US economy. Measuring the dynamic effects from a shock to policy uncertainty within a FAVAR model permits gauging the response of many more variables to policy uncertainty than is possible in a simple VAR model. Our results summarized by impulse responses are all corrected for small sample bias using a bootstrap-after-bootstrap method. Our findings support the view of policy uncertainty exerting a statistically significant influence on the economy, which is however not always as economically significant for a number of variables as found in previous studies.
