Corporate Venture Capital bezeichnet die Finanzierung von Jungunternehmen durch etablierte Firmen. Diese Dissertation untersucht anhand eines Datensatzes die Unterschiede zwischen Venture Capital und Corporate Venture Capital und eruiert die Einflussfaktoren auf das Umsatz- und...

This paper presents a new axiomatic decision theory for choice under uncertainty. Unlike Bayesian decision theory where uncertainty is represented by a probability function, in our theory, uncertainty is given in the form of a likelihood function extracted from statistical evidence. The...

This dissertation consists of four essays which investigate efficiency analysis, especiallywhen non-discretionary inputs exist. A new approach of the multi-stage Data EnvelopmentAnalysis (DEA) for non-discretionary inputs, statistical inference discussions, andapplications are provided. In the...

The analysis of technical efficiency (TE) on the small-scale fishery is relevant for several reasons. While this type of fishery is highly common in developing countries like Mexico, there are a very limited number of analyses assessing their efficiency. Indeed, there is no precise information...

Over the last two decades most European countries have been subject to a strong and persistent increase in their unemployment rates, leading these countries to attempt to combat obdurately high unemployment by exercising measures of Active Labor Market Policy (ALMP). These measures can be...

Despite of the particular importance of wealth as a measure of economic well-being and the various functions of wealth, its distribution on the individual level as well as the reasons for inequality in wealth holdings in Germany have not been fully explored.

We propose a new method to find spatially adaptive smoothing splines. This new method breaks down the interval [0, 1] into p disjoint sub-intervals. Then we define p functional components in [0, 1], which have two importantfeatures. First, the purpose of each of these p components is to estimate...

Determnation of the structure of a medium from normal-incidenceacoustic reflection data is a basic problem in fieldsas diverse as medical technology and the earth sciences; thisresearch examines the accuracy with which quantitative structureestimates can be made from noise-corrupted...

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...
