This thesis contributes to the research in highly skilled migration and takes special interest in questions and concerns of the European Union. The research will look at the causes of migration and what factors cause the selection of migrants. In particular, it will present three empirical...

Die vorliegende Arbeit untersucht wissenschaftlich anhand eines theoretischen Modells, wie sich internationale Migration auf die Volkwirtschaft des Aufnahmelandes auswirkt – nicht nur im Rahmen der EU-Osterweiterung. Kapitel eins enthält neben einer Hinführung zum Thema einen allgemeinen...

We describe a meta-analysis of advertising conversion research findings that includes examining the influence of question framing on key output measures of advertising effectiveness. The article summarizes findings for 32 tourism-advertising studies. Two hypotheses are tested: (H1) the response...

Quantification of welfare changes due to trade liberalisation play a crucial role for political decision making. However, meaningful comparisons of simulation results from different sources are difficult. Often significant differences in simulated gains from liberalisation do not serve to...

The value-of-statistical-life (VSL) approach is used by environmental economists to value mortality changes resulting from environmental improvement, such as decreased urban air pollution. Because of scarce data, VSL estimates are not available for developing countries. Using robust regression...

The selection of appropriate parameters for computable general equilibrium (CGE) models critically affects the results of applied economic modeling exercises. Valid and reliable parameter selection models are needed, and typically comprise direct estimation, expert opinion, or copycatting of...

Using meta-analysis, the current paper reveals a modest difference between Black and White employees in terms of job satisfaction (d = -0.13; k = 65; N = 29,560). Several potential moderators of this relationship were investigated, but only two were supported: the proportion of Black employees in...

OBJECTIVE - to determine the consistency within and between results in empirical studies of software engineering cost estimation. We focus on regression and analogy techniques as these are commonly used. METHOD – we conducted an exhaustive search using predefined inclusion and exclusion...

BACKGROUND – the systematic review is becoming a more commonly employed research instrument in empirical software engineering. Before undue reliance is placed on the outcomes of such reviews it would seem useful to consider the robustness of the approach in this particular research context....

This paper is concerned with the empirical relationship between biodiversity conservation valuesand income. We use random effects panel models to examine the effects of income, and then GDPper capita, on willingness to pay for habitat and biodiversity conservation. In a meta-analysis,...
