Daily news sentiment and monthly surveys: A mixed–frequency dynamic factor model for nowcasting consumer confidence
Working Paper N° 396
Policymakers, firms, and investors closely monitor traditional survey–based consumer confidence indicators and treat it as an important piece of economic information. We propose a latent factor model for the vector of monthly survey–based consumer confidence and daily sentiment embedded in economic media news articles. The proposed mixed– frequency dynamic factor model framework uses a novel covariance matrix specification. Model estimation and real–time filtering of the latent consumer confidence index are computationally simple. In a Monte Carlo simulation study and an empirical application concerning Belgian consumer confidence, we document the economically significant accuracy gains obtained by including daily news sentiment in the dynamic factor model for nowcasting consumer confidence.
