In Germany, the traditional form of formal lectures seems still to be predominant in Entrepreneurship Education. Case studies as a teaching methodology can serve the many dualities of Entrepreneurship Education: heterogeneous vs. homogeneous prior knowledge of participants, participants' divergent interests in entrepreneurship courses, from simply collecting credits to theoretical interest to practical and urgent interest in practical skills for starting a venture. The advantages of case study based teaching methodology in transmitting theoretical knowledge as well as practical skills in entrepreneurship is described, based on the evidence in state of the art entrepreneurship research literature. A small explorative survey on case studies in Entrepreneurship Education is presented. Descriptive results generate insights in students perspective on the usefulness of the case study based teaching methodology in comparison with traditional lectures and provide hints for a more elaborated future empirical study that could employ a proper model on the effectiveness and advantages of case study based learning. The authors conclude in encouraging an increase in the usage of case study based teaching in Entrepreneurship Education especially in Germany.}, language = {en} } @techreport{BraunVoussem, type = {Working Paper}, author = {Braun, Carina N. and Voußem, Ludwig}, title = {Back to Business: Wie Unternehmen ehemalige Auszubildende und Praktikanten an sich binden; Studie im Rahmen eines Projekts an der OTH Regensburg [unver{\"o}ffentlichtes Working Paper]}, language = {en} } @incollection{SassmannshausenVolkmann, author = {Saßmannshausen, Sean Patrick and Volkmann, Christine}, title = {The Emergence of Academic Entrepreneurship at Wuppertal University - A Case Study}, series = {Scientific Entrepreneurship : Reflections on the Success of 10 years EXIST : Festschrift for Norbert Szyperski on the occasion of his 80th birthday, September 27, 2011}, booktitle = {Scientific Entrepreneurship : Reflections on the Success of 10 years EXIST : Festschrift for Norbert Szyperski on the occasion of his 80th birthday, September 27, 2011}, publisher = {Eul}, isbn = {978-3-8441-0078-5}, pages = {19 -- 40}, abstract = {The University of Wuppertal is among the relatively small group of universities which were continuously supported by the EXIST program through all three stages of EXIST I, II, and III. In this article we want to outline the development of "BIZEPS" from 1999 to 2003/04. A subsequent article in this volume will reflect on the development from 2005 to 2011. The acronym BIZEPS has always remained part of the names of follow-up projects and sustainable structures which persisted after the end of government financing. At the end of February 2011, the latest EXIST-project in Wuppertal, BIZEPS gazelles, has been concluded formally; but then again it did not really come to an end, since its core functions can now be continued through internal funding. Sustainable structural changes have been established, and the lessons learned as well as the spirit of BIZEPS gazelles are still present. Now, in summer 2011, Wuppertal is preparing for its second application for EXIST IV. EXIST IV would be the concluding highlight to the university's long-lasting commitment to entrepreneurship by crafting and - more important - incorporating an entrepreneurial strategy not only for parts of the university, but rather for its entire body. But how did Wuppertal University get to this point? In this article we would like to describe the history of entrepreneurship at the University of Wuppertal. This reflection in form of a case study might offer insights and lessons to be learned that are instructive to other universities which are about to start or to advance their entrepreneurial ecosystem (for a similar approach in describing the development of entrepreneurship within educational institutions see e.g. Cruikshank 2005; in addition see e.g. Wright et al.

In this case, an increase in the productivity of skilled workers, and hence their wage, leads to an increase in average income and hence in benefits. The increased fallback income, in turn, makes unskilled workers ask for higher wages. As higher wages are not justified by corresponding productivity increases, unemployment rises. Generally, we show that skill-biased technological change leads to increasing unemployment of the unskilled and to a moderately increasing wage inequality when benefits are endogenous. The model provides a theoretical explanation for diverging dynamics in wage inequality and unemployment under different social benefits regimes. Analysing the social legislation in 14 countries, we find that benefits are linked to the evolution of average income in Continental Europe but not in the US and the UK. Given this institutional difference, our model predicts that skill-biased technological change leads to rising unemployment in Continental Europe and rising wage inequality in the US and the UK.}, language = {en} } @article{Weiss, author = {Weiss, Matthias}, title = {Absenteeism in Age-Diverse Work Teams}, series = {Labour Markets and Demographic Change}, journal = {Labour Markets and Demographic Change}, editor = {Kuhn, Michael and Ochsen, Carsten}, publisher = {VS Verlag}, address = {Wiesbaden}, doi = {10.1007/978-3-531-91478-7_3}, pages = {40 -- 57}, abstract = {Age-diverse work teams are being advocated as an important management tool to enhance performance and productively employ older workers. However, this advice is not founded on empirical evidence. There are very few studies that look at the relation between performance and age diversity of work teams. This lack of evidence is mainly due to a lack of available data. Information on performance and worker composition of a productive unit is available almost exclusively on the plant level in matched employer-employee data sets. But on the plant level/age heterogeneity of the workforce does not tell much about age diversity on the level where co-operation/teamwork takes place (work teams, departments, etc.). If all of the older workers work in the administration whereas all the young employees work in the production, the firm's workforce may be highly age-diverse, but work teams and departments are age-homogeneous. This problem notwithstanding, Grund and Westerg{\aa}rd-Nielsen (2005) look at the relation between productivity and the standard deviation of workers' age in a sample of 7,000 Danish firms.

We advance a general equilibrium model in which increased labor supply reduces unskilled unemployment via consumer demand: longer work hours and higher labor force participation imply higher incomes and less (leisure) time. In consequence, home production is reduced in favor of outsourcing domestic tasks to the market, shifting consumer demand toward unskill-intensive goods. Relative demand for unskilled labor rises and unemployment falls.

They must increase their competitive advantage in the undeniably key process of the issuance of stocks. As the issuance of preferred stocks has increased after the last crisis and in the current period of low interest rates in Europe, they are becoming more favoured investment instruments, we decided to analyse the real properties of preferred stocks in Europe in order to increase the efficiency of joint-stock companies. Using a dataset comprising all companies having both common and preferred stocks issued and traded on European markets between 2009- 2016, we determined the relationship of risk (measured by beta coefficients) and price volatility among common and preferred stocks and bonds in Europe. Our findings show beta coefficients of preferred stocks as systematically lower than beta coefficients of common stocks. Considering a difference of up to 10\% as negligible, however, preferred stocks showed a similar or higher beta coefficient than corresponding common stocks of the same company in 53\% of cases, whereas for 33\% of cases, the difference is only ±10\%. Coefficients of variation in prices showed a similar relationship, with only a negligible portion of preferred stocks bearing fixed (stable) dividends. This result implies that currently traded preferred stocks in Europe in fact do not possess such characteristics they are typically said to have, and in many cases they incur as comparable a risk as do common stocks.
