Abstract
Our primary goal is to analyse the drivers of evolutionary network change processes by using a stochastic actor-based simulation approach. We contribute to the literature by combining two unique datasets, concerning the German laser and automotive industry, between 2002 and 2006 to explore whether geographical, network-related, and techno-logical determinants affect the evolution of networks, and if so, as to what extent these determinants systematically differ for science-driven industries compared to scale-intensive industries. Our results provide empirical evidence for the explanatory power of network-related determinants in both industries. The ‘experience effect’ as well as the ‘transitivity effects’ are significant for both industries but more pronounced for laser manufacturing firms. When it comes to ‘geographical effects’ and ‘technological ef-fects’ the picture changes considerably. While geographical proximity plays an important role in the automotive industry, firms in the laser industry seem to be less dependent on geographical closeness to cooperation partners; instead they rather search out for cooperation opportunities in distance. This might reflect the strong dependence of firms in science-driven industries to access diverse external knowledge, which cannot necessarily be found in the close geographical surrounding. Technological proximity negatively influences cooperation decisions for laser source manufacturers, yet has no impact for automotive firms. In other words, technological heterogeneity seems to ex-plain, at least in science-driven industries, the attractiveness of potential cooperation partners.

Changing Forces of Gravity: How the Crisis Affected International Banking
Claudia M. Buch, Katja Neugebauer, Christoph Schröder
IWH Discussion Papers,
No. 15,
2013
Abstract
The global financial crisis has brought to an end a rather unprecedented period of banks’ international expansion. We analyze the effects of the crisis on international banking. Using a detailed dataset on the international assets of all German banks with foreign affiliates for the years 2002-2011, we study bank internationalization before and during the crisis. Our data allow analyzing not only the international assets of the banks’ headquarters but also of their foreign affiliates. We show that banks have lowered their international assets, both along the extensive and the intensive margin. This withdrawal from foreign markets is the result of changing market conditions, of policy interventions, and of a weakly increasing sensitivity of banks to financial frictions.

Start-up Competitions as an Instrument of Entrepreneurship Policy: The German Experience

European Planning Studies,
No. 10,
2013
Abstract
The number of aspiring entrepreneurs in high-tech industries who successfully complete the transition from a nascent start-up project towards an operational new venture is comparatively low in Germany. Since the mid-1990s, policy-makers have initiated numerous start-up competitions (SUCs or business plan competitions) to facilitate this important step in the venture creation process. SUCs have two key objectives. They are aimed at increasing start-up activity by motivating potential entrepreneurs, while they should also help to increase the likelihood of subsequent entrepreneurial success through providing necessary entrepreneurial skills to prospective entrepreneurs. With our explorative study, we provide the first comprehensive empirical evidence from a cross-sectional survey of existing SUCs in Germany. Overall, 71 SUCs are identified which are analysed regarding their development, regional distribution, and main structural characteristics. Finally, we outline an agenda of future research questions concerning the effectiveness and efficiency of SUCs as an instrument of entrepreneurship policy.

Banks and Sovereign Risk: A Granular View
Claudia M. Buch, Michael Koetter, Jana Ohls
Abstract
In this paper, we use detailed data on the sovereign debt holdings of all German banks to analyse the determinants of sovereign debt exposures and the implications of sovereign exposures for bank risk. Our main findings are as follows. First, sovereign bond holdings are heterogeneous across banks. Larger, weakly capitalised banks and banks with a small depositor base hold more sovereign bonds. Around 31% of all German banks hold no sovereign bonds at all. Second, the sensitivity of banks to macroeconomic factors increased significantly in the post-Lehman period. Banks hold more bonds from euro area countries, from low-inflation countries, and from countries with high sovereign bond yields. Third, there has been no marked impact of sovereign bond holdings on bank risk. This result could indicate the widespread absence of marking-to-market for sovereign bond holdings at the onset of the sovereign debt crisis in Europe.

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.

Do Banks Benefit from Internationalization? Revisiting the Market Power–Risk Nexus
Claudia M. Buch, C. T. Koch, Michael Koetter
Review of Finance,
No. 4,
2013
Abstract
We analyze the impact of bank internationalization on domestic market power (Lerner index) and risk for German banks. Risk is measured by the official declaration of regulatory authorities that a bank is distressed. We distinguish the volume of foreign assets, the number of foreign countries, and different modes of foreign entry. Our analysis has three main results. First, higher market power is associated with lower risk. Second, holding assets in many countries reduce market power at home, but banks with a higher share of foreign assets exhibit higher market power. Third, bank internationalization is only weakly related to bank risk.

Network Formation: R&D Cooperation Propensity and Timing Among German Laser Source Manufacturers
Muhamed Kudic, Andreas Pyka, Marco Sunder
IWH Discussion Papers,
No. 9,
2013
Abstract
Empirical evidence on the evolution of innovation networks within high-tech industries is still scant. We investigate network formation processes by analyzing the timing of firms to enter R&D cooperations, using data on laser source manufacturers in Germany, 1990-2010. Network measures are constructed from a unique industry database that allows us to track both the formation and the termination of ties. Regression results reveal that a firm's knowledge endowment (and cooperation experience) shortens the duration to first (and consecutive) cooperation events. The previous occupation of strategic network positions is closely related to the establishment of further R&D cooperations at a swift pace. Geographic co-location produces mixed results in our analysis.

Proximity and the Transfer of Academic Knowledge: Evidence from the Spatial Pattern of Industry Collaborations of East German Professors
Viktor Slavtchev
Regional Studies,
No. 5,
2013
Abstract
Nähe und Übertragung von akademischem Wissen: Belege aus dem räumlichen Muster der Kooperation zwischen ostdeutschen Professoren und der Industrie, Regional Studies. Universitäten können die ökonomische Entwicklung von Regionen stimulieren, insbesondere durch Kooperation mit der lokalen Industrie. Die vorliegende Studie analysiert, wann solche Kooperationen lokal stattfinden. Die existierende Literatur deutet daraufhin, dass aufgrund von tacidem Wissen und der Bedeutung geographischer Nähe Kooperationen überwiegend lokal stattfinden. Die vorliegende Studie findet Evidenz, dass das räumliche Muster von Kooperationen zwischen Universitäten und der Industrie als Resultat eines komplexen Matching-Prozesses zwischen Partnern mit geeigneten Charakteristika betrachtet werden kann. Die Ergebnisse deuten darauf hin, dass individuelle, relationale sowie institutionelle Charakteristika der Akteure eine wichtige Rolle für die Partnerwahl spielen. Demnach sind lokale Kooperationen nicht zwingend.

Abstract
Nach einer massiven Deindustrialisierung in den frühen 1990er Jahren hat das ostdeutsche Verarbeitende Gewerbe wieder an Fahrt gewonnen. Vor diesem Hintergrund analysiert der Beitrag die dahinter stehenden intra-industriellen Branchen- und Funktionalstrukturen. Es zeigt sich, dass technologieintensive Zweige und hochwertige Dienstleistungsfunktionen unterrepräsentiert sind. Letzteres ist auch eine Folge des weitergehenden Fehlens von Headquarters in Ostdeutschland.

Towards a Theory of Climate Innovation - A Model Framework for Analyzing Drivers and Determinants
Wilfried Ehrenfeld
Journal of Evolutionary Economics,
2013
Abstract
In this article, we describe the results of a multiple case study on the indirect corporate innovation impact of climate change in the Central German chemical industry. We investigate the demands imposed on enterprises in this context as well as the sources, outcomes and determining factors in the innovative process at the corporate level. We argue that climate change drives corporate innovations through various channels. A main finding is that rising energy prices were a key driver for incremental energy efficiency innovations in the enterprises’ production processes. For product innovation, customer requests were a main driver, though often these requests are not directly related to climate issues. The introduction or extension of environmental and energy management systems as well as the certification of these are the most common forms of organizational innovations. For marketing purposes, the topic of climate change was hardly utilized so far. As the most important determinants for corporate climate innovations, corporate structure and flexibility of the product portfolio, political asymmetry regarding environmental regulation and governmental funding were identified.
