This paper investigates the transmission of US macroeconomic shocks to Germany by employing a large-dimensional structural dynamic factor model. This framework allows us to investigate many transmission channels simultaneously, including 'new' channels like stock markets, foreign direct...

We consider the problem of ex-ante forecasting conditional correlation patterns using ultra high frequency data. Flexible semiparametric predictors referring to the class of dynamic panel and dynamic factor models are adopted for daily forecasts. The parsimonious set up of our approach allows to...

This paper empirically analyzes whether the character-based approach, which is based on the personality structure and the human capital of business founders, allows prediction of entrepreneurial success. A unique data set is used consisting of 414 previously unemployed persons whose personal...

In dieser Studie werden die Wirkungen von Arbeitsbeschaffungsmaßnahmen (ABM) in Deutschland auf die individuellen Eingliederungswahrscheinlichkeiten der Teilnehmer in reguläre Beschäftigung evaluiert. Für die Untersuchung wird ein umfangreicher und informativer Datensatz aus den Datenquellen...

Previous empirical studies of job creation schemes in Germany have shown that the average effects for the participating individuals are negative. However, we find that this is not true for all strata of the population. Identifying individual characteristics that are responsible for the effect...

Für Unternehmensdaten existieren im Gegensatz zu Personendaten keine einheitlichen Regeln zur Erstellung von Scientific-Use-Files, d.h. eines anonymisierten Datenfiles zur wissenschaftlichen Nutzung. Verschiedene Anonymisierungsmethoden werden hier vorgestellt. Um Mikrodaten einer breiten...

The stochastic frontier analysis (Aigner et al., 1977, Meeusen and van de Broeck, 1977) is widely used to estimate individual efficiency scores. The basic idea lies in the introduction of an additive error term consisting of a noise and an inefficiency term. Most often the assumption of a...
