Abstract

Many contributions in the recent literature have investigated over the relationship between growth and its volatility, without getting a clear and unambiguous answer. Besides reassessing the well-known effect of output volatility on growth as benchmark analysis, this study aims at looking into the "black box" of the business cycle volatility by disentangling the impacts of volatility of GDP major components - i.e. private consumption, private investment and government expenditure - on growth, simultaneously considered. Our empirical analysis unveils a remarkably robust and strong negative correlation of consumption volatility with mean growth, and a positive one with volatility of investment and of public expenditure. If these findings shed some additional light on the (still controversial) relationship between economic fluctuations and growth, they also make it possible to compare the relative impact of each component, with possibly relevant policy implications. Importantly, this might reconcile opposite views about the issue, in that different empirical results might originate from the relative importance across empirical studies of the various components of volatility.
