Motivated by the variety of bank risk proxies, our analysis reveals that nonperforming assets are a well-suited complement to the Z-score in studies of bank risk.

We investigate four proxies for bank risk that are frequently used in the literature. Our analysis shows that non-performing assets are a good proxy for bank risk for two reasons. First, non-performing assets nest the alternative proxies as shown by the high share of variation in non-performing assets explained by the Z-score, loan loss reserves and loan loss provisions. Second, non-performing assets are well-suited to explain bank failures one year ahead. The latter point also holds for the Z-score whereby the information content of the Z-score seems to differ from the other variables. We conclude that non-performing assets are a well-suited complement to the Z-score, which may come with calculation issues regarding the volatility of profitability, in studies of bank risk.

We identify the determinants of all German banks’ sovereign debt exposures between 2005 and 2013 and test for the implications of these exposures for bank risk. Larger, more capital market affine, and less capitalised banks hold more sovereign bonds. Around 15% of all German banks never hold sovereign bonds during the sample period. The sensitivity of sovereign bond holdings by banks to eurozone membership and inflation increased significantly since the collapse of Lehman Brothers. Since the outbreak of the sovereign debt crisis, banks prefer sovereigns with lower debt ratios and lower bond yields. Finally, we find that riskiness of government bond holdings affects bank risk only since 2010. This confirms the existence of a nexus between government debt and bank risk.

Die Wirtschaft in Ostdeutschland (ohne Berlin) dürfte im Jahr 2015 um 1,5% expandieren. Sie partizipiert dank der engen Integration in den gesamtdeutschen Konjunkturverbund am bundesweiten Aufschwung des privaten Konsums und der Investitionen. Wegen der überwiegenden Orientierung der Exporte auf den Euroraum und die angrenzenden mittel- und osteuropäischen Länder dürfte die ostdeutsche Wirtschaft auch von der dort einsetzenden Erholung profitieren. Allerdings gibt der Handel mit Russland wohl weiter nach.

Nach einem moderaten Start ins Jahr 2015 wird die gesamtwirtschaftliche Produktion in Deutschland wieder etwas mehr Fahrt aufnehmen. Der Produktionszuwachs dürfte im zweiten und im dritten Quartal 2015 mit 0,5% sogar über seiner Potenzialrate liegen. Die Inlandsnachfrage bleibt kräftig, und die Nachfrage aus dem Ausland zieht wieder etwas an. Alles in allem dürfte das reale Bruttoinlandsprodukt im Jahr 2015 um 1,8% steigen (66%-Prognoseintervall: 1,3% bis 2,3%).

Using a unique firm-level sample of approximately 700,000 firm-year observations of German small and medium-sized enterprises (SMEs), this study seeks to identify the effect of bank market power on aggregate growth components. We test for a pre-crisis sample whether bank market power spurs or hinders the reallocation of resources across informationally opaque firms. Identification relies on the dependence on external finance in each industry and the regional demarcation of regional banking markets in Germany. The results show that bank markups spur aggregate SME growth, primarily through technical change and the reallocation of resources. Banks seem to need sufficient markups to generate the necessary private information to allocate financial funds efficiently.

It has been frequently argued that a firm’s location in the core of an industry’s innovation network improves its ability to access information and absorb technological knowledge. The literature has still widely neglected the role of peripheral network positions for innovation processes. In addition to this, little is known about the determinants affecting a peripheral actors’ ability to reach the core. To shed some light on these issues, we have employed a unique longitudinal dataset encompassing the entire population of German laser source manufacturers (LSMs) and laser-related public research organizations (PROs) over a period of more than two decades. The aim of our paper is threefold. First, we analyze the emergence of core–periphery (CP) patterns in the German laser industry. Then, we explore the paths on which LSMs and PROs move from isolated positions toward the core. Finally, we employ non-parametric event history techniques to analyze the extent to which organizational and geographical determinates affect the propensity and timing of network core entries. Our results indicate the emergence and solidification of CP patterns at the overall network level. We also found that the paths on which organizations traverse through the network are characterized by high levels of heterogeneity and volatility. The transition from peripheral to core positions is impacted by organizational characteristics, while an organization’s geographical location does not play a significant role.

Early access to technological knowledge embodied in the industry’s innovation network can provide an important competitive advantage to firms. While the literature provides much evidence on the positive effects of innovation networks on firms’ performance, not much is known about the determinants of firms’ initial entry into such networks. We analyze firms’ timing and propensity to enter the industry’s innovation network. More precisely, we seek to shed some light on the factors affecting the duration between firm founding and its first cooperation event. In doing so, we apply a unique longitudinal event history dataset based on the full population of German laser source manufacturers. Innovation network data stem from official databases providing detailed information on the organizations involved, subject of joint research and development (R&D) efforts as well as start and end times for all publically funded R&D projects between 1990 and 2010. Estimation results from a non-parametric event history model indicate that micro firms enter the network later than small-sized or large firms. An in-depth analysis of the size effects for medium-sized firms provides some unexpected findings. The choice of cooperation type makes no significant difference for the firms’ timing to enter the network. Finally, the analysis of geographical determinants shows that cluster membership can, but do not necessarily, affect a firm’s timing to cooperate.

Does bank instability push borrowers to use crowdfunding as a source of external finance? We identify stressed banks and link them to a unique, manually constructed sample of 157 new ventures seeking equity crowdfunding. The sample comprises projects from all German equity crowdfunding platforms since 2011, which we compare with 200 ventures that do not use crowdfunding. Crowdfunding is significantly more likely for new ventures that interact with stressed banks. Innovative funding is thus particularly relevant when conventional financiers are facing crises. But crowdfunded ventures are generally also more opaque and risky than new ventures that do not use crowdfunding.

Kann es nach einer Herabstufung der Bonität eines Staates zu einer Dynamik von steigenden Zinsen auf Staatsanleihen und weiter fallenden Ratings kommen, die unausweichlich in einem Staatsbankrott endet? Die hohe Persistenz von Ratings sowie die Beobachtung, dass Zinsen häufig negativ auf eine Herabstufung reagieren, legen die Möglichkeit einer solchen Abwärtsspirale nahe. Empirisch ist diese Dynamik allerdings nicht zu sehen. In den Daten ist im Gegenteil ausschließlich eine sehr langsame Annäherung an ein langfristiges Gleichgewicht von guten Ratings und niedrigen Zinsen zu beobachten. Gleichzeitig ist die Persistenz von Ratings allerdings hoch genug, um nach einer Herabstufung auf ein hochspekulatives Niveau (Rating von B oder schlechter) massive und langandauernde Zinsaufschläge zu erzeugen. Da eine solche Herabstufung in der Realität allerdings äußerst selten erfolgt, ist die Existenz des oben beschriebenen Teufelskreises zu verneinen. Eine negative Entwicklung wie zum Beispiel in Griechenland in den Jahren 2010 und 2011 lässt sich nicht als Ergebnis der Wechselwirkung von Ratings und Zinsen erklären.

Das Wirtschaftswachstum in Sachsen-Anhalt war in den vergangenen Jahren schwach. Der wichtigste Erklärungsfaktor ist die demographische Entwicklung; die Alterung und die Schrumpfung der Bevölkerung dämpfen die Anzahl der Erwerbstätigen. Es gibt eine Reihe von ökonomischen Ansatzpunkten für die Verbesserung der wirtschaftlichen Perspektiven. Dazu ist es erforderlich, die Ursachen der schwachen Entwicklung zu analysieren und ursachengerechte Maßnahmen zur Stärkung der wirtschaftlichen Leistungsfähigkeit zu ergreifen. Die größten Chancen bieten Investitionen in die Bildung, mehr Internationalität sowie die Förderung von Forschung und Innovation.
