This paper illustrates the effects of item-nonresponse in surveys on the results of multivariate statistical analysis when estimation of productivity is the task. To multiply impute the missing data a data augmentation algorithm based on a normal/Wishart model is applied. Data of the German IAB...

The sentiment of news predicts the short-term stock market performance of individual companies. We find that this association is solely due to the idiosyncratic informational content of an article. We transparently quantify the association between news sentiment and stock market performance of...

Artificial intelligence (AI) can improve the resiliency of both individual financial institutions and the financial sector as a whole. Yet, its users must balance benefits and risks of these technologies. This paper illustrates five focus points which financial institutions should consider when...

We construct an index for economic policy uncertainty in Denmark using articles in Denmark's largest financial newspaper. We adapt a Latent Dirichlet Allocation (LDA) model to sort articles into topics. We combine article-specific topic weights with the occurrence of words describing uncertainty...

We construct novel proxies of physical and transition climate risks by conducting textual analysis of climate-change news over the period 2000-2018. This analysis uncovers four textual variables related to the topics of U.S. climate policy, international summits, natural disasters, and global...

The German Socio Economic Panel Study (SOEP) offers the rare opportunity to look at patterns of given names amongst a representative sample of more than 50,000 people born since 1900. This article develops an exemplary picture of typical frequency distributions for given names and their...

Previous research into the correlates and determinants of non-response in longitudinal surveys has focused exclusively on why it is that respondents at one survey wave choose not to participate at future waves. This is very understandable if non-response is always an absorbing state, but in many...

Die aktuelle Wirtschaftskrise wirft die Frage auf, ob nicht durch eine bessere Ausschöpfung der in den verschiedenen Frühindikatoren enthaltenen Informationen die aufgetretenen Prognosefehler hätten vermieden werden können. Dies gilt insbesondere vor dem Hintergrund des überraschend...

We propose two new procedures for comparing the mean squared prediction error (MSPE) of a benchmark model to the MSPEs of a small set of alternative models that nest the benchmark. Our procedures compare the bench-mark to all the alternative models simultaneously rather than sequentially, and do...
