Ökonomische Systeme im Wandel der Weltwirtschaft/Economic Systems in a Changing World Economy - Festschrift zum 65. Geburtstag von Professor Dr. Karl Wohlmuth,
2007
Abstract
Prof. Dr. Karl Wohlmuth befasst sich in seinem Werk unter anderem mit Fra-gen der Transformationsökonomik. In frühen Beiträgen zur Transformation der Länder Osteuropas leitet er Empfehlungen für einen erfolgreichen Trans-formationsprozess ab. Im vorliegenden Papier werden zunächst die Arbeiten von Wohlmuth zusammengefasst. Im Anschluss daran werden verschiedene bei Wohlmuth genannte Erfolgsfaktoren für den Transformationsprozess im Sinne einer ex-post Analyse empirisch überprüft. Die zentrale Fragenstellung ist dabei, ob die von Wohlmuth aufgeführten Faktoren einen empirisch signi-fikanten Einfluss auf den Transformationserfolg hatten. Das Ergebnis der em-pirischen Arbeit ist, dass die Faktoren ‚Reform des Unternehmenssektors’, ‚Liberalisierung des Arbeitsmarktes’ und ‚fiskalische Konsolidierung’ von besonderer Bedeutung waren. Damit konnte gezeigt werden, dass die von Wohlmuth schon frühzeitig erkannten Faktoren tatsächlich eine wichtige Rol-le spielten. Seine Empfehlungen sind daher auch für den andauernden Trans-formationsprozess von Bedeutung.

Systematic Mispricing in European Equity Prices?
Marian Berneburg
IWH Discussion Papers,
No. 6,
2007
Abstract
One empirical argument that has been around for some time and that clearly contra- dicts equity market efficiency is that market prices seem too volatile to be optimal estimates of the present value of future discounted cash flows. Based on this, it is deduced that systematic pricing errors occur in equity markets which hence can not be efficient in the Effcient Market Hypothesis sense. The paper tries to show that this so-called excess volatility is to a large extend the result of the underlying assumptions, which are being employed to estimate the present value of cash flows. Using monthly data for three investment style indices from an integrated European Equity market, all usual assumptions are dropped. This is achieved by employing the Gordon Growth Model and using an estimation process for the dividend growth rate that was suggested by Barsky and De Long. In extension to Barsky and De Long, the discount rate is not assumed at some arbitrary level, but it is estimated from the data. In this manner, the empirical results do not rely on the prerequisites of sta- tionary dividends, constant dividend growth rates as well as non-variable discount rates. It is shown that indeed volatility declines considerably, but is not eliminated. Furthermore, it can be seen that the resulting discount factors for the three in- vestment style indices can not be considered equal, which, on a risk-adjusted basis, indicates performance differences in the investment strategies and hence stands in contradiction to an efficient market. Finally, the estimated discount rates under- went a plausibility check, by comparing their general movement to a market based interest rate. Besides the most recent data, the estimated discount rates match the movements of market interest rates fairly well.

Interbank Exposures: An Empirical Examination of Contagion Risk in the Belgian Banking System
Hans Degryse, Grégory Nguyen
International Journal of Central Banking,
No. 2,
2007
Abstract
Robust (cross-border) interbank markets are important for the proper functioning of modern financial systems. However, a network of interbank exposures may lead to domino effects following the event of an initial bank failure. We investigate the evolution and determinants of contagion risk for the Belgian banking system over the period 1993–2002 using detailed information on aggregate interbank exposures of individual banks, large bilateral interbank exposures, and cross-border interbank exposures. The "structure" of the interbank market affects contagion risk. We find that a change from a complete structure (where all banks have symmetric links) toward a "multiplemoney-center" structure (where money centers are symmetrically linked to otherwise disconnected banks) has decreased the risk and impact of contagion. In addition, an increase in the relative importance of cross-border interbank exposures has lowered local contagion risk. However, this reduction may have been compensated by an increase in contagion risk stemming from foreign banks.

Repercusiones de la integración y consolidación de los sectores bancarios europeos sobre la innovación y las actividades de los emprendedores
Hans Degryse, Steven Ongena, Maria Fabiana Penas
Papeles de Economía Española,
No. 110,
2006
Abstract
En este artículo se analiza si el programa de intensificación de la integración del sector financier europeo puede dañar a la innovación y al crecimiento en Europa. En particular, es preciso resaltar los problemas que dicha integración financiera puede ocasionar sobre los últimos avances en materia de desarrollo empresarial. La integración financiera, al intensificar la competencia y la consolidación del sector bancario europeo, podría poner en peligro la financiación procedente de las fuentes más innovadoras. Sin embargo, al sopesar los datos actuales, la conclusión es que estos problemas serían, a lo sumo, transitorios.

The relationship between unemployment and output in post-communist countries
Hubert Gabrisch, Herbert Buscher
Post-Communist Economies,
2006
Abstract
Unemployment is still disappointingly high in most Central and East European countries, and might be a reflection of the ongoing adjustment to institutional shocks resulting from systemic transition, or it may be caused by high labour market rigidity, or aggregate demand that is too weak. In this paper we have investigated the dynamics of unemployment and output in those eight post-communist countries, which entered the EU in 2004. We used a model related to Okun’s Law; i.e. the first differences in unemployment rates were regressed on GDP growth rates. We estimated country and panel regressions with instrument variables (TSLS) and applied a few tests to the data and regression results. We assume transition of labour markets to be accomplished when a robust relationship exists between unemployment rate changes and GDP growth. Moreover, the estimated coefficients contain information about labour market rigidity and unemployment thresholds of output growth. Our results suggest that the transition of labour markets can be regarded as completed since unemployment responds to output changes and not to a changing institutional environment that destroys jobs in the state sector. The regression coefficients have demonstrated that a high trend rate of productivity and a high unemployment intensity of output growth have been occurring since 1998. Therefore, we conclude that labour market rigidities do not play an important role in explaining high unemployment rates. However, GDP growth is dominated by productivity progress and the employment-relevant component of aggregate demand is too low to reduce the high level of unemployment substantially.

Money and Credit Market Integration in an enlarging Euro Zone: Methodological Issues
Johannes Stephan, Jens Hölscher
European Economic Policies - Alteratives to Orthodox Analysis and Policy Concepts,
2006
Abstract
“The chapter discusses methodological issues of money and credit market integration within the context of an enlarging Euro area. Common methods of interest parity tests are rejected in favour of a comparison of nominal interest rates. Hölscher and Stephan find that from an institutional point of view the new EU member countries look under-banked, whereas interest rates are converging. As policy implication the paper argues for a Euro adoption of the new EU members rather sooner than later.“

The IWH signals approach: the present potential for a financial crisis in selected Central and East European countries and Turkey
Hubert Gabrisch, Simone Lösel
Wirtschaft im Wandel,
No. 8,
2006
Abstract
Der hohe Anstieg der Rohölpreise, Gefahren im Zusammenhang mit dem Atomprogramm Irans sowie die Ungewißheit über die künftige Richtung der Politik der großen Zentralbanken haben in den zurückliegenden Monaten auf den internationalen Finanzmärkten eine größere Unsicherheit bei den Anlegern hervorgerufen. Das führte sowohl zu einer höheren Volatilität als auch zu einem Verfall der Kurse an den wichtigen Aktienmärkten. Auch einige wichtige Aktienindizes mittel- und osteuropäischer Länder folgten dem allgemeinen Abwärtstrend, während Staatstitel relativ konstant blieben. Da über mögliche Portfoliokorrekturen internationaler Anleger auch umfangreiche Kapitalabflüsse in den mittel- und osteuropäischen Ländern ausgelöst werden könnten, stellt sich die Frage, ob aus diesen Entwicklungen für die mittel- und osteuropäischen Länder ein erhöhtes Potential für eine Finanzkrise entsteht. Mit Hilfe des IWH-Signalansatzes zur Analyse und Bewertung des Risikos von Finanzkrisen wurde überprüft, ob dies der Fall ist. Wie die Analyse der Frühwarnindikatoren zeigt, ist für die betrachteten Länder der Ausbruch einer Finanzkrise in den nächsten Monaten wenig wahrscheinlich. Durch eine stabile Wirtschaftspolitik und hohe Wachstumsraten, ein robustes Finanzsystem sowie günstige Wechselkursmechanismen sind diese Länder vor externen Angriffen geschützt. Anstiege des Indikators, die beispielsweise bei den baltischen Ländern zu beobachten sind, fielen allenfalls leicht aus. Im Falle der Slowakische Republik und Sloweniens signalisiert der Gesamtindikator sogar eine Entspannung. Für die Tschechische Republik, Polen und Ungarn weisen die Ergebnisse noch auf Probleme im Bankensektor hin. Diese Einschätzung gilt jedoch nicht für Rumänien und insbesondere nicht für die Türkei. Hier deutet der Gesamtindikator auf einen starken Anstieg des Risikopotentials und somit auf einen noch erheblichen wirtschaftspolitischen Handlungsbedarf hin.

Excess Volatility in European Equity Style Indices - New Evidence
Marian Berneburg
IWH Discussion Papers,
No. 16,
2006
Abstract
Are financial markets efficient? One proposition that seems to contradict this is Shiller’s finding of excess volatility in asset prices and its resulting rejection of the discounted cash flow model. This paper replicates Shiller’s approach for a different data set and extends his analysis by testing for a long-run relationship by means of a cointegration analysis. Contrary to previous studies, monthly data for an integrated European stock market is being used, with special attention to equity style investment strategies. On the basis of this analysis’ results, Shiller’s findings seem questionable. While a long-run relationship between prices and dividends can be observed for all equity styles, a certain degree, but to a much smaller extent than in Shiller’s approach, of excess volatility cannot be rejected. But it seems that a further relaxation of Shiller’s assumptions would completely eliminate the finding of an overly strong reaction of prices to changes in dividends. Two interesting side results are, that all three investment styles seem to have equal performance when adjusting for risk, which by itself is an indication for efficiency and that market participants seem to use current dividend payments from one company as an indication for future dividend payments by other firms. Overall the results of this paper lead to the conclusion that efficiency cannot be rejected for an integrated European equity market.
