Abstract
Recent events have highlighted the role of cross-border linkages between banking systems in transmitting local developments across national borders. This paper analyzes whether international linkages in interbank markets affect the stability of interconnected banking systems and channel financial distress within a network consisting of banking systems of the main advanced countries for the period 1994–2012. Methodologically, I use a spatial modeling approach to test for spillovers in cross-border interbank markets. The results suggest that foreign exposures in banking play a significant role in channeling banking risk: I find that countries that are linked through foreign borrowing or lending positions to more stable banking systems abroad are significantly affected by positive spillover effects. From a policy point of view, this implies that in stable times, linkages in the banking system can be beneficial, while they have to be taken with caution in times of financial turmoil affecting the whole system.

Abstract
We investigate credit risk co-movements and contagion in sovereign debt markets of 17 industrialized countries for the period 2008-2012. We use dynamic conditional correlations of sovereign CDS spreads to detect contagion. This approach allows separating the channels through which contagion occurs from the determinants of simple interdependence. The results show that, first, sovereign credit risk comoves considerably, in particular among eurozone countries and during the sovereign debt crisis. Second, contagion cannot be attributed to one moment in time but varies across time and countries. Third, similarities in economic fundamentals, cross-country linkages in banking, and common market sentiment constitute the main channels of contagion.

Finanzielle Instabilität und Krise in den Post-Transformations-Ländern

Abstract
Die Ansteckung durch die globale Finanzkrise war nur ein Auslöser für die schwere Krise in den europäischen Post-Transformations-Ländern. Ursache war die seit 2001 zunehmende finanzielle Instabilität der Länder in Zusammenhang mit der Übernahme ihres Banken- und Finanzsektors durch internationale Finanzinstitutionen. Allgemeine euphorische Renditeerwartungen bildeten den Auftakt für Vermögenspreisblasen und die steigende Verschuldung des privaten Sektors, die durch ausländische Kapitalzuflüsse genährt wurde. Die Studie argumentiert daher, dass simple Konzepte einer Beschränkung inländischer Nachfrage keinen Ausweg aus der Krise weisen. Vielmehr wird eine zweite Transformation notwendig, die ein Wachstumsmodell etabliert, das den Einfluss spekulativer Kapitalzuflüsse reduziert und weiterhin hohe Wachstumsraten ermöglicht.
