Can we use newspaper articles to forecast economic activity? Our answer is yes and, to this aim, we propose a brand new economic dictionary in Italian with valence shifters, and we apply it on a corpus of about two million articles from four popular newspapers. We produce a set of high-frequency text-based sentiment and policy uncertainty indicators (TESI and TEPU, respectively), which are timely, not revised and computed both for the whole economy and for specific sectors or economic topics. To test the predictive power of our text-based indicators, we propose two forecasting exercises. First, using Bayesian Model Averaging (BMA) techniques, we show that our monthly text-based indicators greatly shrink the uncertainty surrounding the short-term forecasts of the main macroeconomic aggregates, especially during recessions. Secondly, we employ these indexes in a weekly GDP growth tracker, delivering sizeable gains in forecasting accuracy in both normal and turbulent times.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
