Abstract: In this paper we consider estimation of unobserved components in state spacemodels using a dynamic factor approach to incorporate auxiliary informationfrom high-dimensional data sources. We apply the methodology to unemploymentestimation as done by Statistics Netherlands, who uses a multivariate statespace model to produce monthly figures for the unemployment using seriesobserved with the labour force survey (LFS). We extend the model by includingauxiliary series of Google Trends about job-search and economic uncertainty,and claimant counts, partially observed at higher frequencies. Our factor modelallows for nowcasting the variable of interest, providing reliable unemploymentestimates in real-time before LFS data become available.
