The Joint Dynamics of Sovereign Ratings and Government Bond Yields
Makram El-Shagi, Gregor von Schweinitz
Abstract
Can a negative shock to sovereign ratings invoke a vicious cycle of increasing government bond yields and further downgrades, ultimately pushing a country toward default? The narratives of public and political discussions, as well as of some widely cited papers, suggest this possibility. In this paper, we will investigate the possible existence of such a vicious cycle. We find no evidence of a bad long-run equilibrium and cannot confirm a negative feedback loop leading into default as a transitory state for all but the very worst ratings.

Direct and Indirect Risk-taking Incentives of Inside Debt
Stefano Colonnello, Giuliano Curatola, Ngoc Giang Hoang
Abstract
We develop a model of managerial compensation structure and asset risk choice. The model provides predictions about the relation between credit spreads and dif-ferent compensation components. First, we show that credit spreads are decreasing in inside debt only if it is unsecured. Second, the relation between credit spreads and equity incentives varies depending on the features of inside debt. We show that credit spreads are increasing in equity incentives. This relation becomes stronger as the seniority of inside debt increases. Using a sample of U.S. public firms with traded credit default swap (CDS) contracts, we provide evidence supportive of the model’s predictions.

Shareholder Bargaining Power and the Emergence of Empty Creditors
Stefano Colonnello, M. Efing, Francesca Zucchi
Abstract
Credit default swaps (CDSs) can create empty creditors who potentially force borrowers into inefficient bankruptcy but also reduce shareholders‘ incentives to default strategically. We show theoretically and empirically that the presence and the effects of empty creditors on firm outcomes depend on the distribution of bargaining power among claimholders. Firms are more likely to have empty creditors if these would face powerful shareholders in debt renegotiation. The empirical evidence confirms that more CDS insurance is written on firms with strong shareholders and that CDSs increase the bankruptcy risk of these same firms. The ensuing effect on firm value is negative.

Do Courts Matter for Firm Value? Evidence from the U.S. Court System
Stefano Colonnello, Christoph Herpfer
Abstract
We estimate the impact of U.S. state court characteristics on firm value by exploiting a U.S. Supreme Court ruling that exogenously changed firms‘ exposure to different courts. We find that increased exposure to more business-friendly courts is associated with positive announcement returns. We find no such association for objective court quality. We confirm that this U.S. Supreme Court ruling impacted firm value through the legal environment channel. We show that this ruling reduced the ability of affected firms to remove cases from certain state courts, and we show that announcement returns are stronger for firms that have high litigation exposure.

Negative Bonitätsbewertungen und Zinsen auf Staatsanleihen – Gibt es einen Teufelskreis?
Makram El-Shagi, Gregor von Schweinitz
Wirtschaft im Wandel,
Nr. 3,
2015
Abstract
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.

The Joint Dynamics of Sovereign Ratings and Government Bond Yields
Makram El-Shagi, Gregor von Schweinitz
Abstract
In the present paper, we build a bivariate semiparametric dynamic panel model to repro-duce the joint dynamics of sovereign ratings and government bond yields. While the individual equations resemble Pesaran-type cointegration models, we allow for different long-run relationships in both equations, nonlinearities in the level effect of ratings, and asymmetric effects in changes of ratings and yields. We find that the interest rate equation and the rating equation imply significantly different long-run relationships. While the high persistence in both interest rates and ratings might lead to the misconception that they follow a unit root process, the joint analysis reveals that they converge slowly to a joint equilibrium. While this indicates that there is no vicious cycle driving countries into default, the persistence of ratings is high enough that a rating shock can have substantial costs. Generally, the interest rate adjusts rather quickly to the risk premium that is in line with the rating. For most ratings, this risk premium is only marginal. However, it becomes substantial when ratings are downgraded to highly speculative (a rating of B) or lower. Rating shocks that drive the rating below this threshold can increase the interest rate sharply, and for a long time. Yet, simulation studies based on our estimations show that it is highly improbable that rating agencies can be made responsible for the most dramatic spikes in interest rates.

Cross-border Interbank Networks, Banking Risk and Contagion
Lena Tonzer
Journal of Financial Stability,
2015
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.

Risk and Return - Is there an Unholy Cycle of Ratings and Yields?
Makram El-Shagi, Gregor von Schweinitz
Economics Letters,
2015
Abstract
After every major financial crisis, the question about the responsibility of the rating agencies resurfaces. Regarding government bonds, the most frequently voiced concern targeted “unreasonably” bad ratings that might trigger capital flights and increasing risk premia which sanction further rating downgrades. In this paper we develop a multivariate, nonparametric version of the Pesaran type cointegration model that allows for nonlinearities, to show that a unique equilibrium between ratings and sovereign yields exists. Therefore, we have to reject the concern that there is an unholy cycle leading to certain default in the long run.

Corporate Governance Structures and Financial Constraints in Multinational Enterprises – An Analysis in Selected European Transition Economies on the Basis of the IWH FDI Micro Database 2013 –
Andrea Gauselmann, Felix Noth
IWH Discussion Papers,
Nr. 3,
2015
Abstract
In our analysis, we consider the distribution of decision power over financing and investment between MNEs’ headquarters and foreign subsidiaries and its influence on the foreign affiliates’ financial restrictions. Our research results show that headquarters of multinational enterprises have not (yet) moved much decision power to their foreign subsidiaries at all. We use data from the IWH FDI Micro Database which contains information on corporate governance structures and financial restrictions of 609 enterprises with a foreign investor in Hungary, Poland, the Czech Republic, Slovakia, Romania and East Germany. We match data from Bureau van Dijk’s AMADEUS database on financial characteristics. We find that a high concentration of decision power within the MNE’s headquarter implicates high financial restrictions within the subsidiary. Square term results show, however, that the effect of financial constraints within the subsidiary decreases and finally turns insignificant when decision power moves from headquarter to subsidiary. Thus, economic policy should encourage foreign investors in the case of foreign acquisition of local enterprises to leave decision power within the enterprise and in the case of Greenfield investment to provide the newly established subsidiaries with as much power over corporate governance structures as possible.

American Economic Review,
Nr. 12,
2014
Abstract
Private equity critics claim that leveraged buyouts bring huge job losses and few gains in operating performance. To evaluate these claims, we construct and analyze a new dataset that covers US buyouts from 1980 to 2005. We track 3,200 target firms and their 150,000 establishments before and after acquisition, comparing to controls defined by industry, size, age, and prior growth. Buyouts lead to modest net job losses but large increases in gross job creation and destruction. Buyouts also bring TFP gains at target firms, mainly through accelerated exit of less productive establishments and greater entry of highly productive ones.
