Despite the enormous reach and influence of the literature on economic and economic policy uncertainty, the forecasting performance of economic uncertainty measures has been surprisingly under-researched. We evaluate the ability of several popular measures of uncertainty to forecast in-sample and out-of-sample over real and financial outcome variables, as well as over different quantiles of the GDP growth distribution. Real-time data and estimation considerations are highly consequential, owing to look-ahead bias. We construct new real-time versions of both macroeconomic (Jurado et al. (2015)) and financial uncertainty (Luvigson et al (forthcoming)), and analyze them together with their ex-post counterparts. We find some explanatory power in all uncertainty measures, with relatively good performance by ex-post macroeconomic uncertainty (MU), which has additional in-sample predictive content over the widely-used excess bond premium of Gilchrist and Zakrajsek (2012) and the National Financial Conditions Index (NFCI). However, real-time MU performs poorly compared to its ex-post counterpart, a finding that we relate to sub-sample instability in the performance of ex-post MU.
