A Weighty Issue Revisited: The Dynamic Effect of Body Weight on Earnings and Satisfaction in Germany
Frieder Kropfhäußer, Marco Sunder
Abstract
We estimate the relationship between changes in the body mass index (bmi) and wages or satisfaction, respectively, in a panel of German employees. In contrast to previous literature, the dynamic models indicate that there is an inverse u-shaped association between bmi and wages among young workers. Among young male workers, work satisfaction is affected beyond the effect on earnings. Our finding of an implied optimum bmi in the overweight range could indicate that the recent rise in weight does not yet constitute a major limitation to productivity.

Who Invests in Home Equity to Exempt Wealth from Bankruptcy?
S. Corradin, Reint E. Gropp, H. Huizinga, Luc Laeven
Abstract
Homestead exemptions to personal bankruptcy allow households to retain their home equity up to a limit determined at the state level. Households that may experience bankruptcy thus have an incentive to bias their portfolios towards home equity. Using US household data for the period 1996 to 2006, we find that household demand for real estate is relatively high if the marginal investment in home equity is covered by the exemption. The home equity bias is more pronounced for younger households that face more financial uncertainty and therefore have a higher ex ante probability of bankruptcy.

Survival of Spinoffs and Other Startups: First Evidence for the Private Sector in Germany, 1976-2008
Daniel Fackler, Claus Schnabel
Abstract
Using a 50 percent sample of all establishments in the German private sector, we report that spinoffs are larger and initially employ more skilled and more experienced workers than other startups. Controlling for these and other differences, we find that spinoffs are less likely to exit than other startups. We show that in West and East Germany and in all sectors investigated pulled spinoffs (where the parent company continues after they are founded) generally have the lowest exit hazards, followed by pushed spinoffs (where the parent company stops operations). The difference between both types of spinoffs is particularly pronounced in the first three years. Contrary to expectations, intra-industry spinoffs are not found to have lower exit hazards in our sample.

Technological Intensity of Government Demand and Innovation
Viktor Slavtchev, Simon Wiederhold
Abstract
Governments purchase everything from airplanes to zucchini. This paper investigates whether the technological intensity of government demand affects corporate R&D activities. In a quality-ladder model of endogenous growth, we show that an increase in the share of government purchases in high-tech industries increases the rewards for innovation, and stimulates private-sector R&D at the aggregate level. We test this prediction using administrative data on federal procurement performed in US states. Both panel fixed effects and instrumental variable estimations provide results in line with the model. Our findings bring public procurement within the realm of the innovation policy debate.

Spillover Effects among Financial Institutions: A State-dependent Sensitivity Value-at-Risk Approach
Z. Adams, R. Füss, Reint E. Gropp
Abstract
In this paper, we develop a state-dependent sensitivity value-at-risk (SDSVaR) approach that enables us to quantify the direction, size, and duration of risk spillovers among financial institutions as a function of the state of financial markets (tranquil, normal, and volatile). Within a system of quantile regressions for four sets of major financial institutions (commercial banks, investment banks, hedge funds, and insurance companies) we show that while small during normal times, equivalent shocks lead to considerable spillover effects in volatile market periods. Commercial banks and, especially, hedge funds appear to play a major role in the transmission of shocks to other financial institutions. Using daily data, we can trace out the spillover effects over time in a set of impulse response functions and find that they reach their peak after 10 to 15 days.

Specialization, Diversity, Competition and their Impact on Local Economic Growth in Germany
Martin T. W. Rosenfeld, Annette Illy, Michael Schwartz, Christoph Hornych
Abstract
This study systematically examines the impact of fundamental elements of urban economic structure on urban growth in Germany from 2003 to 2007. We test four elements simultaneously, that is sectoral specialization, diversification of economic activities, urban size as well as the impact of local competition. To account for the effect of varying spatial delimitations in the analysis of urban growth, we further differentiate between cities and planning regions as geographical units. The analysis covers manufacturing industries as well as service sectors. Most previous work produces inconsistent results and concentrates on localization economies and/or diversification, while urban size and the effect of local competition are widely ignored. Our regression results show a U-shaped relationship between localization economies and urban growth and positive effects of local competition on urban growth. With respect to diversification, we find positive effects on urban growth on the city-level, but insignificant results on the level of the planning regions. The impact of urban size also differs between free cities and planning regions; in the former a U-shaped relationship is found whereas the effect is inversely U-shaped for the latter.

Informal Networking - An Overview of the Literature and an Agenda for Future Research
Michael Schwartz, Christoph Hornych
Abstract
Informelle Netzwerkstrukturen bieten vielfältige Möglichkeiten, den Transfer von Informationen, Wissen und Technologie zwischen Akteuren zu organisieren. In Anbetracht des Potentials sowie der Bedeutung informeller Netzwerke ist der bestehende Mangel an theoretischen Diskussionen wie auch empirischer Forschung überraschend. Hier setzt der Beitrag an, indem eine Bündelung der bislang lediglich in Fragmenten vorliegenden Auseinandersetzung mit dem Konzept informeller Netzwerke vorgenommen wird. Der Fokus wird dabei auf Fragen der Entstehung solcher Netzwerkstrukturen sowie auf diejenigen Faktoren gelegt, die notwendig sind, informelle Netzwerke als effektiven und beständigen Kanal des Wissens- und Technologietransfers nutzbar zu machen. In einem zweiten Teil des Beitrags wird ein Überblick über die wichtigsten, zum gegenwärtigen Zeitpunkt existierenden, Studien gegeben, die sich empirisch mit dem Konzept informeller Netzwerkstrukturen auseinandersetzen. Basierend auf dieser Aufarbeitung werden anschließend fünf wichtige Forschungsfragen formuliert, die im Fokus zukünftiger Forschungsbestrebungen stehen sollten.

Government Interventions in Banking Crises: Assessing Alternative Schemes in a Banking Model of Debt Overhang
Diemo Dietrich, Achim Hauck
Abstract
In dieser Studie werden verschiedene Politikmaßnahmen evaluiert, die ergriffen werden können, um den Rückgang des Kreditangebots im Geiner Bankenkrise aufzuhalten. Es wird ein dynamischer Ansatz entwickelt, in dem Banken aufgrund eines bestehenden Schuldenüberhangs einen Anreiz haben, das Kreditangebot zu reduzieren oder eine fragile Kapitalstruktur zu wählen. Staatliche Unterstützungsmaßnahmen, die von neuen Bankgeschäften abhängig gemacht werden, erlauben es den Banken, das Ausmaß der Unterstützung zu beeinflussen und Risiken zu externalisieren; damit targen die Maßnahmen dazu bei, dass Banken das Kreditangebot unangemessen stark ausweiten und/oder exzessive Risiken eingehen. Unterstützungsmaßnahmen ohne Bezug auf neue Bankgeschäfte führen nicht zu diesen adversen Anreizeffekten, sind aber mit höheren fiskalischen Kosten verbunden.
