In Pleier und Mangold (2013) wurde ein Pilotprojekt zur Verbesserung des Lernverhaltens untersucht, welches im Wintersemester 2012/2013 durchgeführt wurde. Studierende sollten dabei semesterbegleitend an Online-Tests teilnehmen, um sich frühzeitig auf die abschließende Klausur vorzubereiten....

Nonparametric prediction of time series is a viable alternative to parametric prediction, since parametric prediction relies on the correct specification of the process, its order and the distribution of the innovations. Often these are not known and have to be estimated from the data. Another...

The problem of selecting a prior distribution when it comes to Bayes estimation often constitutes a choice between conjugate or noninformative priors, since in both cases the resulting posterior Bayes estimator (PBE) can be solved analytically and is therefore easy to calculate. Nevertheless,...

This paper estimates ability peer effects on achievement growth in reading and math. It exploits variation in peer characteristics generated at the transition from primary to secondary school in a sample of Berlin fifth-graders. As will be discussed in detail, this variation is exogenous in...

Using a large linked employer–employee dataset from Germany, I investigate workers' decision to introduce a works council as an exit-voice consideration. Thereby, I explore the collective voice face of introductions, while previous studies focus on the monopoly aspect. Controlling for...

This paper analyzes assortative matching between employers and employees and its interrelations with the employment density of local labor markets in Germany. I devote attention to the identiication of accurate quality measures: plants’ total factor productivity and workers’ fixed effect....

This paper looks inside the firm and investigates how trade alters the matching of worker-specific abilities and task-specific skill requirements. The outcome of this matching depends on how firms organize their recruitment process and how much they invest into the screening of applicants. In...

We propose exible models for multivariate realized volatility dynamics which involve generalizations of the Box-Cox transform to the matrix case. The matrix Box-Cox model of realized covariances (MBC-RCov) is based on transformations of the covariance matrix eigenvalues, while for the Box-Cox...

The scarcity of talent is a tremendous challenge for firms in the globalized world. This paper investigates the role of labor market imperfection in open economies for the usage of talent in the production process of firms. For this purpose, I set up a heterogeneous firms model, where production...

Do contractual institutions and a country’s level of trust interact in their impact on the international make-or-buy decision? By analyzing explicit and implicit contracting in a unified framework, I show that better formal contractibility may both facilitate and hinder relational contracting...
