Monetary Policy and Green Investment Impacts: Evidence from Exchange-Traded Funds

Abstract

In this paper we revisit the busy debate over the relationship between volatility and growth, to separate out the effects on growth that come from short run and long run episodes of uncertainty. Employing this time series perspective, we reconcile the theoretical ambiguities and explain the conflicting differences in empirical studies of this important linkage. We suggest that the relationship depends on the type of volatility responsible for driving economic fluctuations; volatility that reflects longer run positive characteristics is positively associated with economic growth, with shorter spells of uncertainty associated with poorer macroeconomic outcomes. Stabilisation policy needs to discriminate between good volatility and bad volatility.
