The Laffer curve revisited
Mathias Trabandt, Harald Uhlig
Journal of Monetary Economics,
Nr. 4,
2011
Abstract
Laffer curves for the US, the EU-14 and individual European countries are compared, using a neoclassical growth model featuring “constant Frisch elasticity” (CFE) preferences. New tax rate data is provided. The US can maximally increase tax revenues by 30% with labor taxes and 6% with capital taxes. We obtain 8% and 1% for the EU-14. There, 54% of a labor tax cut and 79% of a capital tax cut are self-financing. The consumption tax Laffer curve does not peak. Endogenous growth and human capital accumulation affect the results quantitatively. Household heterogeneity may not be important, while transition matters greatly.

Mergers, Spinoffs, and Employee Incentives
Paolo Fulghieri, Merih Sevilir
Review of Financial Studies,
Nr. 7,
2011
Abstract
This article studies mergers between competing firms and shows that while such mergers reduce the level of product market competition, they may have an adverse effect on employee incentives to innovate. In industries where value creation depends on innovation and development of new products, mergers are likely to be inefficient even though they increase the market power of the post-merger firm. In such industries, a stand-alone structure where independent firms compete both in the product market and in the market for employee human capital leads to a greater profitability. Furthermore, our analysis shows that multidivisional firms can improve employee incentives and increase firm value by reducing firm size through a spinoff transaction, although doing so eliminates the economies of scale advantage of being a larger firm and the benefits of operating an internal capital market within the firm. Finally, our article suggests that established firms can benefit from creating their own competition in the product and labor markets by accommodating new firm entry, and the desire to do so is greater at the intermediate stages of industry/product development.

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.

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.
