Endogenous Selection of Comparison Groups, Human Capital Formation, and Tax Policy

Economica,
Nr. 313,

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.

Human Capital Investment, New Firm Creation and Venture Capital
Merih Sevilir
Journal of Financial Intermediation,
Nr. 4,
2010
Abstract
This paper studies the relation between firm investment in general human capital, new firm creation and financial development for new firm financing, such as the existence of a venture capital industry. On one hand, firm investment in general human capital leads employees to generate new innovative ideas for starting their own firm. Since employees need a venture capitalist to start their new firm, firm investment in general human capital encourages the creation of venture capitalists by increasing the need for their services, such as providing advice and monitoring. On the other hand, as new firm financing becomes available, firms' willingness to invest in general human capital increases, and as a by-product, the creation of employee-founded and venture capital-backed new firms increases in the economy. Hence, our model provides a rational explanation for the emergence of new firms created by employees of established firms, which represents one of the most common type of new firms in many industries.

Human Capital and Fertility in Germany after 1990: Evidence from a Multi-Spell Model
Marco Sunder
IWH Discussion Papers,
Nr. 22,
2009
Abstract
We analyze the timing of birth of the first three children based on German panel
data (GSOEP) within a hazard rate framework. A random effects estimator is
used to accommodate correlation across spells. We consider the role of human
capital – approximated by a Mincer-type regression – and its gender-specific
effects on postponement of parenthood and possible recuperation at higherorder
births. An advantage of the use of panel data in this context consists in
its prospective nature, so that determinants of fertility can be measured when
at risk rather than ex-post, thus helping to reduce the risk of reverse causality.
The analysis finds evidence for strong recuperation effects, i.e., women with
greater human capital endowments follow, on average, a different birth history
trajectory, but with negligible curtailment of completed fertility.

Size and Focus of a Venture Capitalist's Portfolio
Paolo Fulghieri, Merih Sevilir
Review of Financial Studies,
Nr. 11,
2009
Abstract
We take a portfolio approach to analyze the investment strategy of a venture capitalist (VC) and show that portfolio size and scope affect both the entrepreneurs' and the VC's incentives to exert effort. A small portfolio improves entrepreneurial incentives because it allows the VC to concentrate the limited human capital on a smaller number of startups, adding more value. A large and focused portfolio is beneficial because it allows the VC to reallocate the limited resources and human capital in the case of startup failure and allows the VC to extract greater rents from the entrepreneurs. We show that the VC finds it optimal to limit portfolio size when startups have higher payoff potential - that is, when providing strong entrepreneurial incentives is most valuable. The VC expands portfolio size only when startup fundamentals are more moderate and when he can form a sufficiently focused portfolio. Finally, we show that the VC may find it optimal to engage in portfolio management by divesting some of the startups early since this strategy allows him to extract a greater surplus.

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.

Foreign Subsidiaries in the East German Innovation System – Evidence from Manufacturing Industries
Jutta Günther, Björn Jindra, Johannes Stephan
IWH Discussion Papers,
Nr. 4,
2008
Abstract
This paper analyses the extent of technological capability of foreign subsidiaries located in East Germany, and looks at the determinants of foreign subsidiaries’ technological sourcing behaviour. The theory of international production underlines the importance of strategic and regional level variables. However, existing empirical approaches omit by and large regional level factors. We employ survey evidence from the “FDI micro data- base” of the IWH, that was only recently made available, to conduct our analyses. We find that foreign subsidiaries are above average technologically active in comparison to the whole East German manufacturing. This can be partially explained by the industrial structure of foreign direct investment. However, only a limited share of foreign subsidiaries with R&D and/or innovation activity source technological knowledge from the East German innovation system. If a subsidiary follows a competence augmenting strategy or does local trade, it is more likely to source technological knowledge locally. The endowment of a region with human capital and a scientific infrastructure has a positive effect too. The findings suggest that foreign subsidiaries in East Germany are only partially linked with the regional innovation system. Policy implications are discussed.

The Role of the Human Capital and Managerial Skills in Explaining the Productivity Gaps between East and West
Wolfgang Steffen, Johannes Stephan
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.

Firm-Specific Determinants of Productivity Gaps between East and West German Industrial Branches
Johannes Stephan
East-West Journal of Economics and Business,
2006
Abstract
This research assesses the firm-specific reasons for lower producitivity levels between West and East German firms. The study is based on a unique data-base generated by field-work in the two particularly important sectors of machinery manufacturers and furniture manufacturers. Our results suggest that the quality of human capital plays an important role in explaining lower productivity levels, as well as particularly networking activities, and the use of modern technologies for communication. Classifying those as management-functions beyond the organisation of the production process itself, we identify management deficits as the main specific determinants of productivity gaps between West and East German firms.

Economic Capability of East German Regions: Results of a Cluster Analysis
Franz Kronthaler
Regional Studies,
Nr. 6,
2005
Abstract
This paper analyses the economic capability of East German regions compared with West German regions. Based on new growth theory and new economic geography, and using relevant empirical literature, regions are clustered according to a set of growth factors. The clustering results find little evidence that the economic capability of East German regions is already comparable with West German regions. Economic disadvantages are particularly rooted in lower technical progress, a lack of entrepreneurship, lower business and industrial concentration, and a loss of human capital. However, there are a few East German regions with a high economic capability, but even those suffer from economic disadvantages such as lower technical progress, lower industrial activity and a poorer regional accessibility.
