Abstract
This paper examines the effects of bank alliance network on bonds issued by European banks during the period 1990–2009. We construct six measures capturing different dimensions of banks’ network characteristics. In opposition to the results obtained for non-financial firms, our findings indicate that being part of a network does not create value for bank’s bondholders, indicating a dark side effect of strategic alliances in the banking sector. While being part of a network is perceived as a risk-increasing event by market participants, this negative perception is significantly lower for the larger banks, and, to a lesser extent, for the more profitable banks. Moreover, during crisis times, the positive impact on bond spread of a bank’s higher centrality or of a bank’s higher connectedness in the network is stronger, indicating that market participants may fear spillover effects within the network during periods of banks’ heightened financial fragility.

Criminal Network Formation and Optimal Detection Policy: The Role of Cascade of Detection

Abstract
This paper investigates the effect of cascade of detection, how detection of a criminal triggers detection of his network neighbors, on criminal network formation. We develop a model in which criminals choose both links and actions. We show that the degree of cascade of detection plays an important role in shaping equilibrium criminal networks. Surprisingly, greater cascade of detection could reduce ex ante social welfare. In particular, we prove that full cascade of detection yields a weakly denser criminal network than that under partial cascade of detection. We further characterize the optimal allocation of the detection resource and demonstrate that it should be highly asymmetric among ex ante identical agents.

International Regional Science Review,
No. 3,
2017
Abstract
Subsidies for research and development (R&D) are an important tool of public R&D policy, which motivates extensive scientific analyses and evaluations. This article adds to this literature by arguing that the effects of R&D subsidies go beyond the extension of organizations’ monetary resources invested into R&D. It is argued that collaboration induced by subsidized joint R&D projects yield significant effects that are missed in traditional analyses. An empirical study on the level of German labor market regions substantiates this claim, showing that collaborative R&D subsidies impact regions’ innovation growth when providing access to related variety and embedding regions into central positions in cross-regional knowledge networks.

The Forward-looking Disclosures of Corporate Managers: Theory and Evidence
Reint E. Gropp, Rasa Karapandza, Julian Opferkuch
IWH Discussion Papers,
No. 25,
2016
Abstract
We consider an infinitely repeated game in which a privately informed, long-lived manager raises funds from short-lived investors in order to finance a project. The manager can signal project quality to investors by making a (possibly costly) forward-looking disclosure about her project’s potential for success. We find that if the manager’s disclosures are costly, she will never release forward-looking statements that do not convey information to external investors. Furthermore, managers of firms that are transparent and face significant disclosure-related costs will refrain from forward-looking disclosures. In contrast, managers of opaque and profitable firms will follow a policy of accurate disclosures. To test our findings empirically, we devise an index that captures the quantity of forward-looking disclosures in public firms’ 10-K reports, and relate it to multiple firm characteristics. For opaque firms, our index is positively correlated with a firm’s profitability and financing needs. For transparent firms, there is only a weak relation between our index and firm fundamentals. Furthermore, the overall level of forward-looking disclosures declined significantly between 2001 and 2009, possibly as a result of the 2002 Sarbanes-Oxley Act.

The Structure and Evolution of Inter-sectoral Technological Complementarity in R&D in Germany from 1990 to 2011
T. Broekel, Matthias Brachert
Journal of Evolutionary Economics,
No. 4,
2015
Abstract
Technological complementarity is argued to be a crucial element for effective R&D collaboration. The real structure is, however, still largely unknown. Based on the argument that organizations’ knowledge resources must fit for enabling collective learning and innovation, we use the co-occurrence of firms in collaborative R&D projects in Germany to assess inter-sectoral technological complementarity between 129 sectors. The results are mapped as complementarity space for the Germany economy. The space and its dynamics from 1990 to 2011 are analyzed by means of social network analysis. The results illustrate sectors being complements both from a dyadic and portfolio/network perspective. This latter is important, as complementarities may only become fully effective when integrated in a complete set of different knowledge resources from multiple sectors. The dynamic perspective moreover reveals the shifting demand for knowledge resources among sectors at different time periods.

The Impact of Risk Attitudes on Financial Investments
Walter Hyll, Maike Irrek
IWH Discussion Papers,
No. 10,
2015
Abstract
Several scholars analyze the relationship between individuals’ willingness to take risks and financial investment decisions. We add to this literature in using data from the German Socio-Economic Panel which allow ruling out that investments in risky assets itself impact on risk attitudes. We show that individuals with a higher willingness to take risks are more likely to hold bonds, stocks, and company assets. When grouping individuals into risk groups, our results reveal that high risk takers are also less likely to own a life insurance. If endogenous adaption of risk attitudes from holding assets in previous years is not taken into account, the impact of risk attitudes on holding risky assets is upward biased.

Im Fokus: Sächsische Kooperationsstrukturen im 7. Forschungsrahmenprogramm der Europäischen Union

Wirtschaft im Wandel,
No. 6,
2014
Abstract
Im Bereich Forschung und Entwicklung (FuE) bieten zwischenbetriebliche Kooperationen die Möglichkeit, Spezialisierungsvorteile zu nutzen und Wissen auszutauschen. Für die Entstehung von Innovationen ist insbesondere personengebundenes Wissen wichtig, dessen Ausbreitung jedoch räumlich begrenzt ist. Für die Innovationsdynamik einer Region sind deswegen neben überregionalen Beziehungen auch regionale Kooperationen bedeutsam. Der vorliegende Beitrag analysiert die Kooperationsstrukturen innerhalb geförderter Verbundprojekte des 7. Forschungsrahmenprogramms der Europäischen Union (EU) für den Zeitraum von 2007 bis 2013. Die Untersuchung richtet sich auf den Freistaat Sachsen. Der Beitrag knüpft an eine Untersuchung aus dem Jahr 2013 an, die zeigte, dass sächsische Akteure in einer bestimmten Art von Förderprogrammen, den Bundesprogrammen, heute vergleichsweise viele Kooperationspartner in räumlicher Nähe wählen. Es zeigt sich, dass es formelle Kooperationen zwischen sächsischen Akteuren auch innerhalb der internationalen Konsortien der Forschungsrahmenprogramme der EU gibt. Damit ist der Grundstein für den Austausch von personengebundenem Wissen gelegt. Aus internationaler Perspektive waren in den angesprochenen Projekten vorwiegend Partner aus Westeuropa beteiligt.

Im Fokus: Geförderte FuE-Verbundprojekte: Sächsische Akteure wählen zunehmend Partner in räumlicher Nähe

Abstract
Externe Kooperationen bei innovativen Projekten sind mit einer Reihe von Vorteilen verbunden. Oft werden solche Projekte durch Kooperationen überhaupt erst möglich. Die Literatur stellt dabei insbesondere den Austausch von Wissen heraus. Für den Austausch einer ganz besonderen Form des Wissens, des so genannten nicht kodifizierten Wissens, ist oftmals räumliche Nähe erforderlich, da nicht kodifiziertes Wissen überwiegend durch persönliche Kontakte ausgetauscht wird. Der Bund und die Länder wenden eine ganze Reihe von Förderprogrammen an, die Anreize zur Aufnahme von innovativen Kooperationsprojekten bieten. Der vorliegende Beitrag analysiert die Kooperationsstrukturen innerhalb geförderter Verbundprojekte des Bundes in den Zeiträumen 1995 bis 2000 und 2005 bis 2010. Die Untersuchung richtet sich auf den Freistaat Sachsen. Es zeigt sich, dass die sächsischen Akteure im zweiten Zeitraum mehr Partner innerhalb Sachsens und der ostdeutschen Länder gewählt haben als in der ersten Periode. Dies spricht offenbar dafür, dass sächsische Partner attraktiver werden, und ermöglicht durch die räumliche Nähe den stärkeren Austausch von nicht kodifiziertem Wissen, welches wichtig für den Erfolg von Innovationsaktivitäten einer Region ist.
