Studie zeigt Milliardenlücke im AfD-Programm für Sachsen-AnhaltReint GroppHandelsblatt, 6. August 2026
In this paper we test the ability of three of the most popular methods to forecast the South African currency crisis of June 2006. In particular we are interested in the out-ofsample performance of these methods. Thus, we choose the latest crisis to conduct an out-of-sample experiment. In sum, the signals approach was not able to forecast the outof- sample crisis of correctly; the probit approach was able to predict the crisis but just with models, that were based on raw data. Employing a Markov-regime-switching approach also allows to predict the out-of-sample crisis. The answer to the question of which method made the run in forecasting the June 2006 currency crisis is: the Markovswitching approach, since it called most of the pre-crisis periods correctly. However, the “victory” is not straightforward. In-sample, the probit models perform remarkably well and it is also able to detect, at least to some extent, out-of-sample currency crises before their occurrence. It can, therefore, not be recommended to focus on one approach only when evaluating the risk for currency crises.
This paper analyses in a simple global games framework welfare effects of different communication strategies of a central bank: it can either publish no more than its overall assessment of the economy or be more transparent, giving detailed reasons for this assessment. The latter strategy is shown to be superior because it enables agents to use private information and to be less dependent on common knowledge. This result holds true even if the strategies of agents are strategic complements, for which case it has been argued that too much transparency might induce agents to neglect their private knowledge.
The last decades were characterized by large increases in world trade, not only in absolute terms, but also in relation to world GDP. This was in large parts caused by increasing exchanges of parts and components between countries as a consequence of international fragmentation of production. Apparently, greater competition especially from the Newly Industrializing and Post-Communist Economies prompted firms in ‘high-wage’ countries to exploit international factor price differences in order to increase their international competitiveness. However, theory predicts that, beside factor price differences, vertical disintegration of production should be driven by a multitude of additional factors. Against this background, the present paper reveals empirical evidence on parts and components trade as an indicator for international fragmentation of production in the European Union. On the basis of a panel data approach, the main explanatory factors for international fragmentation of production are determined. The results show that, although their influence can not be neglected, factor price differences are only one out of many causes for shifting production to or sourcing components from foreign countries.
The paper explores what macroeconomic factors can tell us about the effectiveness of recently enacted national competition laws. Qualitative evidence suggests that numerous countries fall short in implementing competition law. Furthermore, there seems to be significant differences between countries. To examine what factors might contribute to the explanation of effectiveness of competition law panel regression analysis is used. The results indicate that the level of economic development matters, however the institutional learning curve is also relevant. Furthermore, larger countries should be more concerned with competition advocacy activities than smaller countries and it seems to be the case that the problem of capture of competition law is serious in countries with high levels of corruption.
In this paper we study interdependencies between corporate foreign investment and the capital structure of banks. By committing to invest predominantly at home, firms can reduce the credit default risk of their lending banks. Therefore, banks can refinance loans to a larger extent through deposits thereby reducing firms’ effective financing costs. Firms thus have an incentive to allocate resources inefficiently as they then save on financing costs. We argue that imposing minimum capital adequacy for banks can eliminate this incentive by putting a lower bound on financing costs. However, the Basel II framework is shown to miss this potential.
Die vorliegende Arbeit untersucht die möglichen Effekte der Basel II-Bankenregulierung auf die Transmission von Währungskrisen zu Bankenkrisen. Die Analyse des Beispiels Südkorea zeigt die wichtige Rolle der Unausgeglichenheit von Bankaktiva und -passiva in bezug auf deren Fristigkeit und Währung bei diesem Transmissionsprozess und stellt dar wie Basel II auf die Bankenbilanzen gewirkt hätte. Es wird gezeigt, dass die regulatorischen Kapitalanforderungen unter Basel II, aufgrund der guten Kreditratings im Vorfeld der Krise, geringer gewesen wären als unter Basel I. Dadurch wäre die Krise verschärft worden. Im zweiten Teil der Arbeit wird analysiert, ob die Ratingagenturen ihr Verhalten seit dem Versagen bei der Prognose der Asienkrise geändert haben. Dieser Beitrag findet keine empirische Evidenz für eine Berücksichtigung der Unausgeglichenheit in den Bankenbilanzen bei der Ableitung von Ratingergebnissen für Länder. Deshalb muss die Effektivität von Basel II bei der Prävention der Transmission von Währungs- zu Bankenkrisen sowohl im Falle Südkoreas als auch bei möglichen zukünftigen Krisen angezweifelt werden.
Die aktuelle Diskussion zur Reform des Instrumentariums des IWF beinhaltet Vorschläge zur Implementierung eines International-Lender-of-Last-Resort (ILOLR). Die Debatte lässt jedoch offen, wie die konkrete Implementierung erfolgen soll. Dieser Beitrag diskutiert sechs verschiedene ILOLR-Optionen, die Notenbanken im Falle von Währungskrisen unterstützen. Es wird geschlussfolgert, dass direkte Interventionen des ILOLR zur Unterstützung der betroffenen Währung zu bevorzugen sind. Dazu verwendet der IWF eigene Ressourcen und Rechte auf weitere Ziehungen im Bedarfsfall. Als Kriterien werden Momente der Kosteneffizienz wie z.B. Kosten der Zahlerländer, Kosten der Kreditaufnahme, der Intervention und der Sterilisation sowie Moral-Hazard- Probleme berücksichtigt.
This paper studies how capital requirements influence a bank’s mode of entry into foreign financial markets. We develop a model of an internationally operating bank that creates and allocates liquidity across countries and argue that the advantage of multinational banking over offering cross-border financial services depends on the benefit and the cost of intimacy with local markets. The benefit is that it allows to create more liquidity. The cost is that it causes inefficiencies in internal capital markets, on which a multinational bank relies to allocate liquidity across countries. Capital requirements affect this trade-off by influencing the degree of inefficiency in internal capital markets.
Currency crises episodes of 1996, 1998, and 2001 are used to identify common country specific causes of currency crises in South Africa. The paper identifies crises by the use of an Exchange Market Pressure (EMP) index as introduced by Eichengreen, Rose and Wyplosz (1996). It extends the Signals Approach introduced by Kaminsky and Reinhart (1996, 1998) by developing a composite indicator in order to measure the evolution of currency crisis risk in South Africa. The analysis considers the standard suspects from international currency crises and country specifics as identified by the Myburgh Commission (2002) and current literature as potentially relevant indicators.
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.
