Components of uncertainty

Vegard Larsen

No 2017/5, Working Paper from Norges Bank

Abstract: Uncertainty is acknowledged to be a source of economic fluctuations. But, does the type of uncertainty matter for the economy's response to an uncertainty shock? This paper offers a novel identi cation strategy to disentangle different types of uncertainty. It uses machine learning techniques to classify different types of news instead of specifying a set of keywords. It is found that, depending on its source, the effects of uncertainty on macroeconomic variable may differ. I find that both good(expansionary effect) and bad (contractionary effect) types of uncertainty exist.
