Abstract
We examine whether scientists employed in foreign countries and foreign-educated native researchers are more “entrepreneurial” than their “domestic” counterparts. We conjecture that foreign-born and foreign-educated scientists possess broader scientific skills and social capital, which increases their likelihood that they will start their own companies. To test this hypothesis we analyze comprehensive data from researchers at the Max Planck Society in Germany. Our findings provide strong support for the conjecture that academic entrepreneurship can be stimulated by facilitating the mobility of scientists across countries.

International Fragmentation of Production and the Labour Input into Germany’s Exports – An Input-Output-analysis
Hans-Ulrich Brautzsch, Udo Ludwig
IWH Discussion Papers,
Nr. 14,
2011
Abstract
The import penetration of exports has become a topic of public debate, particularly in the context of Germany’s position as one of the world’s leading exporters. The growth in the volume of intermediate products purchased from abroad for subsequent processing into export goods in Germany seems to be undermining the importance of exports as a driver of domestic production and employment. The gains that arise from an increase in exports seem to have been offset by the losses caused by the crowding out of local production by imports. Empirical evidence on the impact of this international integration of the goods market on the German labour market is ambiguous. Short-term negative effects on employment are claimed to be offset by the long-term benefit that the jobs lost in the short run will eventually be replaced by higher-skilled jobs with better
perspectives. Against this background, the following hypothesis is tested empirically: Germany is poor in natural resources, but rich in skilled labour. In line with the Heckscher- Ohlin theory, Germany should therefore specialize in the production of export goods and services that are relatively intensive in these factors and should import those goods and services that are relatively intensive in unskilled labour. The empirical part of the paper deals with the extent of the German export penetration by imports. At first, it analyses by what ways imports are affecting the exports directly and indirectly and shows the consequences of import penetration of exports for the national output and employment. Secondly, consequences for employment are split in different skill types of labour. These issues are discussed with the standard open static inputoutput- model. The data base is a time series of official input-output tables. The employment effects for Germany divided by skill types of labour are investigated using skill matrices generated by the authors.

Endogenous Selection of Comparison Groups, Human Capital Formation, and Tax Policy
Oded Stark, Walter Hyll, Y. Wang
Economica,
Nr. 313,
2012
Abstract
We consider a setting in which the acquisition of human capital entails a change of location in social space that causes individuals to revise their comparison groups. Skill levels are viewed as occupational groups. Moving up the skill ladder by acquiring additional human capital, in itself rewarding, leads to a shift in the individual’s inclination to compare himself with a different, and on average better-paid, comparison group, in itself penalizing. We shed new light on the dynamics of human capital formation, and suggest novel policy interventions to encourage human capital formation in the aggregate and reduce inter-group income inequality.

Innovation and Skills from a Sectoral Perspective: A Linked Employer-Employee Analysis
Lutz Schneider, Jutta Günther, Bianca Brandenburg
Economics of Innovation and New Technology,
2010
Abstract
Natur- und ingenieurwissenschaftliche Fähigkeiten sowie Management- und Führungskompetenzen werden häufig als Quelle von betrieblichen Innovationsaktivitäten betrachtet. Der vorliegende Artikel untersucht die Rolle von Humankapital im Sinne des formalen Bildungsabschlusses und des tatsächlich ausgeübten Berufes für die betriebliche Innovationstätigkeit im Rahmen eines Probit-Ansatzes, wobei zwischen sektoralen Innovationsregimen unterschieden wird. Die Analyse basiert auf einem Mikrodatensatz deutscher Betriebe (LIAB), welcher detaillierte Informationen über die Innovationsaktivitäten und die Qualifikation der Beschäftigten, verstanden als formaler Ausbildungsabschluss, ausgeübter Beruf und Erfahrung, enthält. Es zeigen sich signifikante Unterschiede der Humankapitalausstattung zwischen Sektoren, welche nach der Pavitt-Klassifikation unterschieden wurden. Sektoren mit einem hohen Anteil hochqualifizierter Beschäftigter sind überdurchschnittlich oft unter den Produktinnovatoren zu finden (spezialisierte Zulieferer und wissenschaftsbezogene Branchen). Indes lassen sich in den realisierten Regressionen keine signifikant positiven Effekte der Beschäftigtenqualifikation auf die Innovationstätigkeit eines Betriebes nachweisen.

Effects of Heterogeneity on Bank Efficiency Scores

Nr. 1,

Abstract
Bank efficiency estimates often serve as a proxy of managerial skill since they quantify sub-optimal production choices. But such deviations can also be due to omitted systematic differences among banks. In this study, we examine the effects of heterogeneity on bank efficiency scores. We compare different specifications of a stochastic cost and alternative profit frontier model with a baseline specification. After conducting a specification test, we discuss heterogeneity effects on efficiency levels, ranks and the tails of the efficiency distribution. We find that heterogeneity controls influence both banks’ optimal costs and profits and their ability to be efficient. Differences in efficiency scores are important for more than only methodological reasons. First, different ways of accounting for heterogeneity result in estimates of foregone profits and additional costs that are significantly different from what we infer from our general specification. Second, banks are significantly re-ranked when their efficiency is estimated with a specification other than the preferred, general specification. Third, the general specification gives the most reliable estimates of the probability of distress, although differences to the other specifications are low.

Low Skill but High Volatility?
Claudia M. Buch
CESifo Working Paper No. 2665,
2009
Abstract
Globalization may impose a double-burden on low-skilled workers. On the one hand, the relative supply of low-skilled labor increases. This suppresses wages of low-skilled workers and/or increases their unemployment rates. On the other hand, low-skilled workers typically face more limited access to financial markets than high-skilled workers. This limits their ability to smooth shocks to income intertemporally and to share risks across borders. Using cross-country, industry-level data for the years 1970 - 2004, we document how the volatility of hours worked and of wages of workers at different skill levels has changed over time. We develop a stylized theoretical model that is consistent with the empirical evidence, and we test the predictions of the model. Our results show that greater financial globalization and development increases the volatility of employment, and this effect is strongest for low-skilled workers. A higher share of low-skilled employment has a dampening impact.

The Role of the Human Capital and Managerial Skills in Explaining the Productivity Gaps between East and West
Johannes Stephan, Wolfgang Steffen
Eastern European Economics,
Nr. 6,
2008
Abstract
Die Veröffentlichung beschäftigt sich mit den Determinanten von Produktivitätsgefällen zwischen Firmen in Europäischen Transitionsländern oder –regionen und Firmen in Westdeutschland. Die Analyse findet auf der Unternehmensebene statt und basiert auf einer einzigartigen Datenbank, welche durch Feldforschung erstellt worden ist. Die Determinanten werden in einer einfachen ökonometrischen Regression getestet und fokussieren auf Humankapital und modernes marktorientiertes Management. Die Ergebnisse sind insofern neu als sie eine Lösung anbieten, wie die widersprüchlichen Ergebnisse anderer Analysen zu formalen Qualifikationsmustern in Ost- und Westdeutschland zu erklären sind. Darüber hinaus ist es aufgrund der Analyse möglich eine Art Humankapital und Expertise zu entwickeln, welche meist in post-sozialistischen Firmen gebraucht wird und sich auf bestimmte Ansprüche an eine konkurrenzfähige marktbasierte ökonomische Umwelt bezieht. Letztendlich findet die Analyse auch empirische Beweise für die Rolle einer verbesserten Kapitalausstattung für den Produktivitätsausgleich sowie für das Argument, dass die Unterschiede in Arbeitsproduktivität bedeutend in einer größeren arbeitsintensiveren Produktion verwurzelt sind, was jedoch nicht zu einem wettbewerblichen Nachteil führt.

An Assessment of Bank Merger Success in Germany
Michael Koetter
German Economic Review,
Nr. 2,
2008
Abstract
German banks have experienced a merger wave since the early 1990s. However, the success of bank mergers remains a continuous matter of debate.This paper suggests a taxonomy to evaluate post-merger performance on the basis of cost and profit efficiency (CE and PE). I identify successful mergers as those that fulfill simultaneously two criteria. First, merged institutes must exhibit efficiency levels above the average of non-merging banks. Second, banks must exhibit efficiency changes between merger and evaluation year above efficiency changes of non-merging banks. I assess the post-merger performance up to 11 years after the mergers and relate it to the transfer of skills, the adequacy to merge distressed banks and the role of geographical distance. Roughly every second merger is a success in terms of either CE or PE. The margin of success in terms of CE is narrow, as efficiency differentials between merging and non-merging banks are around 1 and 2 percentage points. PE performance is slightly larger. More importantly, mergers boost in particular the change in PE, thus indicating persistent improvements of merging banks to improve the ability to generate profits.

The Role of the Human Capital and Managerial Skills in Explaining the Productivity Gaps between East and West

IWH Discussion Papers,
Nr. 11,
2007
Abstract
This paper assess determinants of productivity gaps between firms in the European transition countries and regions and firms in West Germany. The analysis is conducted at the firm level by use of a unique database constructed by field work. The determinants tested in a simple econometric regression model are focussed upon the issue of human capital and modern market-oriented management. The results are novel in as much as a solution was established for the puzzling results in related research with respect to a comparison of formal qualification between East and West. Furthermore, the analysis was able to establish that the kind of human capital and expertise mostly needed in the post-socialist firms are related to the particular requirements of a competitive marketbased economic environment. Finally, the analysis also finds empirical support for the role of capital deepening in productivity catch-up, as well as the case that the gaps in labour productivity are most importantly rooted in a more labour-intense production, which does not give rise to a competitive disadvantage.

Does Qualification Drive Innovation? A Microeconometric Analysis Using Linked-employer-employee Data
Bianca Brandenburg, Jutta Günther, Lutz Schneider
IWH Discussion Papers,
Nr. 10,
2007
Abstract
Degree-level science and engineering skills as well as management and leadership skills are often referred to as a source of innovative activities within companies. Broken down by sectoral innovation patterns, this article examines the role of formal education and actual occupation for product innovation performance in manufacturing firms within a probit model. It uses unique micro data for Germany (LIAB) that contain detailed information about innovative activities and the qualification of employees. We find significant differences of the human capital endowment between sectors differentiated according to the Pavitt classification. Sectors with a high share of highly skilled employees engage in product innovation above average (specialized suppliers and science based industries). According to our hitherto estimation results, within these sectors the share of highly skilled employees does not, however, substantially increase the probability to be an innovative firm.
