Volatility, Growth and Financial Crises

This research group analyses the build-up of financial vulnerabilities and real consequences of financial crises. Different policy shocks and the causal reaction of macroeconomic aggregates are identified. Early-warning models describe the cyclical nature of financial vulnerabilities.

Potential Effects of Basel II on the Transmission from Currency Crises to Banking Crises – The Case of South Korea

Tobias Knedlik Johannes Ströbel

in: Journal of Money, No. 13, 2010

Abstract

In this paper we evaluate potential effects of the Basel II accord on preventing the transmission from currency crises to banking crises by analyzing the South Korean crisis of 1997. We show that regulatory capital reserves under Basel II would have been lower than those under Basel I, and that therefore Basel II would have had adverse effects on the development of the crisis. Furthermore we investigate whether the behavior of rating agencies has changed since the East Asian crisis. We find no evidence that rating agencies have started to take micro-mismatches into account. Thus, we have reservations concerning the effectiveness of Basel II.

Die Bedeutung der Besitzverflechtung von Kapitalgesellschaften für die Finanzkrise

Makram El-Shagi C. Ilgmann

in: ORDO, 2010

Abstract

Im vorliegenden Papier wird die Bedeutung der Besitzverflechtungen zwischen Aktiengesellschaften (bzw. Kapitalgesellschaften im Allgemeinen) für die gegenwärtige Finanzmarktkrise herausgearbeitet. Durch den wechselseitigen Besitz von Firmen untereinander ist eine Situation entstanden, in denen bestellte Manager sich lediglich kontrollieren. Durch entstehende Abhängigkeiten und die innerhalb der verhältnismäßig kleinen Gruppe von Topmanagern mögliche implizite Koordination konnten Vorstände über die Entlohnungs- und damit auch über die Anreizsysteme, denen sie ausgesetzt sind, wesentlich mitentscheiden. Dies hat, wie gezeigt wird, erheblich zur Entstehung von Anreizsystemen beigetragen, die sich im Kern an kurzfristigen Erfolgen orientieren. Da insbesondere in der Finanzintermediation kurz- und langfristige Gewinnoptimierung durch die starke Korrelation von Risiko und Gewinnmöglichkeiten einem starken Trade- off unterliegen, haben diese Anreizsysteme wiederum eine erhebliche Rolle in der verfehlten Risikopolitik der Banken gespielt, die ein wesentliche Ursache der Krise war.

Finanzielle Instabilität und Krise in den Post-Transformations-Ländern

Hubert Gabrisch

in: Wirtschaftspolitische Blätter, No. 3, 2009

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.

Much Ado About Nothing: Sovereign Ratings and Government Bond Yields in the OECD

Makram El-Shagi

in: IWH Discussion Papers, No. 22, 2016

Abstract

In this paper, we propose a new method to assess the impact of sovereign ratings on sovereign bond yields. We estimate the impulse response of the interest rate, following a change in the rating. Since ratings are ordinal and moreover extremely persistent, it proves difficult to estimate those impulse response functions using a VAR modeling ratings, yields and other macroeconomic indicators. However, given the highly stochastic nature of the precise timing of ratings, we can treat most rating adjustments as shocks. We thus no longer rely on a VAR for shock identification, making the estimation of the corresponding IRFs well suited for so called local projections – that is estimating impulse response functions through a series of separate direct forecasts over different horizons. Yet, the rare occurrence of ratings makes impulse response functions estimated through that procedure highly sensitive to individual observations, resulting in implausibly volatile impulse responses. We propose an augmentation to restrict jointly estimated local projections in a way that produces economically plausible impulse response functions.

Exit Expectations and Debt Crises in Currency Unions

Alexander Kriwoluzky G. J. Müller M. Wolf

in: IWH Discussion Papers, No. 18, 2015

Abstract

Membership in a currency union is not irreversible. Exit expectations may emerge during sovereign debt crises, because exit allows countries to reduce their liabilities through a currency redenomination. As market participants anticipate this possibility, sovereign debt crises intensify. We establish this formally within a small open economy model of changing policy regimes. The model permits explosive dynamics of debt and sovereign yields inside currency unions and allows us to distinguish between exit expectations and those of an outright default. By estimating the model on Greek data, we quantify the contribution of exit expectations to the crisis dynamics during 2009 to 2012.

Flight Patterns and Yields of European Government Bonds

Gregor von Schweinitz

in: IWH Discussion Papers, No. 10, 2013

Abstract

The current European Debt Crisis has led to a reinforced effort to identify the sources of risk and their influence on yields of European Government Bonds. Until now, the potentially nonlinear influence and the theoretical need for interactions reflecting flight-to-quality and flight-to-liquidity has been widely disregarded. I estimate government bond yields of the Euro-12 countries without Luxembourg from May 2003 until December 2011. Using penalized spline regression, I find that the effect of most explanatory variables is highly nonlinear. These nonlinearities, together with flight patterns of flight-to-quality and flight-to-liquidity, can explain the co-movement of bond yields until September 2008 and the huge amount of differentiation during the financial and the European debt crisis without the unnecessary assumption of a structural break. The main effects are credit risk and flight-to-liquidity, while the evidence for the existence of flight-to-quality and liquidity risk (the latter measured by the bid-ask spread and total turnover of bonds) is comparably weak.
