At the beginning of their career civil servants in Germany can choose between the social health insurance (SHI) system and a private plan combined with a direct reimbursement of the government of up to 70 percent. Most civil servants chose the latter, not only but also because they have to cover all contribution payments in the social system themselves, while normal employees get nearly 50 percent from their employers. The city state of Hamburg decided to change the system by paying a share of the contributions if civil servants choose the social plan. We use a stochastic microsimulation model to analyse which socio-economic types of civil servants could benefit from the Hamburg plan and if this changes the mix of insured persons in the SHI system. Our results show that low income and high morbidity types as well as families have a substantially higher incentive to choose SHI. This reform might thereby increase the adverse selection of high risk cases towards SHI.
Der Bericht präsentiert empirische Befunde zum wissenschaftlichen Nachwuchs in Deutschland. Schwerpunktthema des Berichtes ist die Vereinbarkeit von Familie und akademischer Karriere. Weitere Themen sind Arbeits- und Beschäftigungsbedingungen, Qualifizierungsbedingungen in der Promotionsphase sowie Karrierewege und -perspektiven, insbesondere in der Post-Doc-Phase. Das Mobilitätsverhalten und der Beitrag zu Forschung, Lehre und Transfer des wissenschaftlichen Nachwuchses sowie Bildungsrenditen der Promotion werden ebenfalls in den Blick genommen.
Basis des Berichtes sind primär Daten aus der amtlichen Statistik sowie aus regelmäßig durchgeführten Befragungen. Bei der Aufbereitung der Daten liegt der Fokus stärker als bisher auf der Vergleichbarkeit und Einordnung der Befunde. Damit schafft der Bericht eine Wissensbasis für Hochschulen und Forschungseinrichtungen, Interessenvertretungen, Förderorganisationen und Entscheidungsträger/innen in Bund und Ländern.
In diesem Beitrag wird die Expansion eines Samples von 47 HDAX-Unternehmen zwischen 1995 und 2004 hinsichtlich des Expansionsverlaufs, der Expansionsrichtung (Internationalisierung und Diversifikation) und der Expansionsumsetzung beschrieben. Die Betrachtung von 1.830 einzelnen Expansionsschritten führt zu einem detaillierten und umfassenden Bild der Expansionspfade dieser Unternehmen. Insgesamt zeigt sich, dass die Entwicklung der betrachteten Unternehmen sehr heterogen verläuft. Hieraus ergeben sich verschiedene interessante Fragestellungen und Implikationen für die weitere Forschung zur Expansion von Unternehmen. Vor allem scheint es fraglich, ob die bisherige Praxis, Internationalisierung und Produktdiversifikation getrennt zu betrachten, dem Phänomen der Expansion von Unternehmen gerecht wird.
The paper analyzes firms' expansion paths within and across industries and specifically different patterns along these paths. Using a procedure previously applied in statistical process control and employing longitudinal data on the expansion of 91 German firms, we analyzed firms' clustering behavior regarding different characteristics. Results reveal that expansion is a heterogeneous process: the clustering behavior along the expansion path does not only differ between firms, but also within one firm regarding different characteristics of its expansion path.
Changes in the regulatory framework allow German business schools to select an important part of their students by themselves for the first time through entrance exams. We analyze if the students participating in these entrance exams differ from average first-year business students and which factors influence their choice of a business school. A separate analysis for a cluster of very highly motivated students reveals that for these students a short study time and a practical Orientation are of utmost importance as decision criteria. We derive suggestions for German business schools that want to target this specific segment of students.

This paper looks at the value-relevance of accounting data and measures of web-traffic for Internet firms listed on the Neuer Markt. In particular, the objective is to identify value drivers during the period from October 1999 to May 2000. In doing so, the study attempts to contribute to the understanding of the investment behaviour of market participants during that time, in a market environment characterised by rapid technological change and growth. The study subdivides Internet companies into Ecommerce and Enabler firms and analyses the value-relevance accordingly. It emerged that, across both samples, no significant value-relevance of traditionally applied financial valuation metrics such as earnings and cashflow could be evidenced. However, a positive association of total sales with market capitalisation can be shown for both samples, and in addition, sales and marketing expenses (Ecommerce) as well as research and development costs (Enabler) can also be identified as value drivers. Furthermore, the paper finds a number of webmetrics to be highly value-relevant and positively associated with market capitalisation, viz. customer loyalty, reach, page impressions and unique visitors. Combining and comparing the information content and value-relevance supports the notion that webmetrics, which are not part of standardised reporting regulations, did provide at least as much explanatory power for variations in market value as standardised accounting data.
