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.

Do Banks Benefit from Internationalization? Revisiting the Market Power-Risk Nexus
Claudia M. Buch, C. T. Koch, Michael Koetter
Abstract
Recent developments on international financial markets have called the benefits of
bank globalization into question. Large, internationally active banks have
acquired substantial market power, and international activities have not
necessarily made banks less risky. Yet, surprisingly little is known about the
actual link between bank internationalization, bank risk, and market power.
Analyzing this link is the purpose of this paper. We jointly estimate the
determinants of risk and market power of banks, and we analyze the effects of
changes in terms of the number of foreign countries (the extensive margin) and
the volume of foreign assets (the intensive margin). Our paper has four main
findings. First, there is a strong negative feedback effect between risk and market
power. Second, banks with higher shares of foreign assets, in particular those held
through foreign branches, have higher market power at home. Third, holding
assets in a large number of foreign countries tends to increase bank risk. Fourth,
the impact of internationalization differs across banks from different banking
groups and of different size.
