Macroeconomic and Microeconomic Effects of Migration
This book consists of three major studies, which are connected through the topic of migration. The first chapter gives a general overview of results. The second chapter shows that the model specifications, which connect high ethnic fractionalisation to lower growth, cannot fully explain the negative ethnic fractionalisation effect of the 1990s and Sub-Saharan African growth experience. Furthermore, an empirical investigation provides evidence that ethnic fractionalisation has a positive effect in a nation which is ethnically diverse due to immigration. The third chapter sheds light on the behavioural effects of inter-family transfers, which is still rare. Incentive effects of inter-family tr...
Becoming an Entrepreneur
This book provides new insights into the important field of Entrepreneurship Education. The editors pick up Fayolle’s invitation: “How can we learn from ‘institutional’ culture?” and translate it to a variety of aspects of learning to start-up. From the perspective of Human Resource Education and Management (Wirtschaftspädagogik) the authors shed light into the socio-cultural system of entrepreneurship education. They start with mapping out its challenges. They discuss context factors like political regimes affecting entrepreneurial activities, consider goals including moral awareness, introduce ideas of modeling entre- and intrapreneurial competencies, suggest teaching-learning-strategies, discuss evaluation procedures and introduce case studies of entrepreneurship education in different countries for different study levels. All in all this book stimulates and supports the challenges of educators, students, and practitioners (human resource managers, consultants, principals, teachers, and trainers) to introduce into the varying contexts of entrepreneurship education content specific, procedural, causal elements necessary for starting and maintaining an enterprise.
Socio-Cognitive Dynamics in Strategic Processes
Process-related considerations in strategy research and approaches to managerial cognition constitute two highly valuable, yet still only limitedly integrated, fields of interest in strategic management. To fill this void, the work starts from a cognitive perspective with the overall aim of examining the emergence of organisational strategies in strategic processes. The central research object 'strategy' is thereby conceptualized as shared strategic orientations among an organisation's key actors. The existing gap between strategy process research and cognitive strategy research is closed on a conceptual level first by developing and specifying a socio-cognitive perspective on strategic proc...
New Perspectives on the Role of Information in Health Economics
Does managed care reduce the costs of medical care while leaving the quality of treatment at least unchanged? What instruments should be employed to prevent risk selection? How can medical decision making be based on more rational criteria? This book consists of three major studies, each addressing a specific question related to the current debate on reforms in the health care sector. Insurers offering managed care contracts have the right to deny coverage for treatment prescribed by an insured's physician. In the US, such practices have provoked a wave of criticism against managed care. The first study shows that monitoring physicians' decisions can generally raise the efficiency of health ...
Dynamic Copulas for Finance
The interactions of financial securities are crucial to determine possible portfolio losses. Although this fact is well understood, two questions remain: What causes changes in the dependence structure of financial assets? How can fluctuating dependencies be measured? The most common approach to identify the amplitude of financial assets' interactions are linear correlation coefficients. However, they fail to comprise shifts in the dependence structure. Alternatively, Copulas are a more flexible dependence measurement. This book focuses on the development of Dynamic Copula frameworks by implementing stochastic parameters into Archimedian and Elliptical Copula functions. In contrast to static...
On Copula Density Estimation and Measures of Multivariate Association
Measuring the degree of association between random variables is a task inherent in many practical applications such as risk management and financial modeling. Well-known measures like Spearman's rho and Kendall's tau can be expressed in terms of the underlying copula only, hence, being independent of the underlying univariate marginal distributions. Opposed to these classical measures of association, mutual information, which is derived from information theory, constitutes a fundamentally different approach of measuring association. Although this measure is likewise independent of the univariate margins, it is not a functional of the copula but of the corresponding copula density. Besides th...
Contributions to Static and Time-varying Copula-based Modeling of Multivariate Association
Putting a particular emphasis on nonparametric methods that rely on modern empirical process techniques, the author contributes to the theory of static and time-varying stochastic models for multivariate association based on the concept of copulas. These functions enable a profound understanding of multivariate association, which is pivotal for judging whether a large set of risky assets entails diversification effects or aggravates risk from an entrepreneurial point of view. Since serial dependence is a stylized fact of financial time series, an asymptotic theory for estimating the structure of association in this context is developed under weak assumptions. A new measure of multivariate as...
External Embeddedness of Subsidiaries
In the research fields of International Business and International Management it is stated that product innovations are not only developed by headquarters (HQs) but also by foreign subsidiaries. Subsidiaries thereby apply the knowledge they obtain in inter-organizational business relationships with stakeholders like customers, suppliers, competitors, research institutions or governmental organizations. After being finished, product innovations are either exclusively employed by the creative subsidiaries or they are also transferred in intra-organizational business relationships to other units of the MNC, i. e. HQs or other subsidiaries. This book deals with both the product innovation proces...
