Die Arbeit untersucht und vergleicht die Wirkung von Mindest- und Kombilöhnen (Lohnkostenzuschüsse und Transferzahlungen an Arbeitnehmer) in einem Arbeitsmarktmodell mit monopsonistischer Konkurrenz und freiem Marktzutritt für Firmen. Es wird die Wirkung beider Instrumente auf die Nutzen der...

In empirischen und theoretischen Untersuchungen wird die Rolle von Verträgen für das Zustandekommen von ökonomischen Transaktionen auf Arbeitsmärkten betont. Da die Investitionstätigkeit in Sach- und Humankapital sowie in Forschung und Entwicklung häufig spezifisch erfolgt, ist es...

This thesis deals with the employment double dividend (EDD) hypothesis which claims that an ecological tax reform leads to both a reduction in the unemployment rate and to lower pollution. It assesses the employment effects of ecological tax reforms in a computable general equilibrium (CGE)...

Diese Arbeit präsentiert ein neuartiges mikroökonomisch fundiertes Arbeitsmarktmodell in einem partiellen Gleichgewichtsmodell. Als Theoriegerüst wird der Rahmen wiederholter Spiele in Verbindung mit dem modernen mikroökonomischen Konzept der Bounded Rationality gewählt. Die entscheidenden...

We consider the problem of model assessment by risk estimation. Variousapproaches to risk estimation are considered in a uni ed framework. This a discussion of various complexity dimensions and approaches to obtainingbounds on covering numbers is also presented.The second type of training sample...

Previous research implementing stratification on the propensity score has generally relied on using five strata, based on prior theoretical groundwork and minimal empirical evidence as to the suitability of quintiles to adequately reduce bias in all cases and across all sample sizes. This study...

In terms of risk measurement, probability and quantile risk estimation have developed enormously in the past decade, from value-at-risk measures to coherent measures such as expected shortfall. These measures allow an investor to determine their risk profile accounting for losses (quantiles) at...

To overcome the curse of dimensionality, dimension reduction is important andnecessary for understanding the underlying phenomena in a variety of fields.Dimension reduction is the transformation of high-dimensional data into ameaningful representation in the low-dimensional space. It can be...

This thesis is concerned with simulation output analysis. In particular, we are inter-ested in estimating the variance parameter of a steady-state output process. The estimationof the variance parameter has immediate applications in problems involving (i) the precisionof the sample mean as a...
