Abstract
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.

The IWH signals approach: the present potential for a financial crisis in selected Central and East European countries and Turkey

No. 8,

Abstract
The steep increase of oil prices, general threats rooting from Iran’s nuclear program, and doubts about the future policy of important central banks recently caused more uncertainties of investors on international financial markets. This explains the higher volatility and the fall of indices on stock markets including those of some Central and East European countries. International investors could respond with adjustments of their portfolio and trigger off a financial crisis. On this background, the article studies the potential for a financial crises in the region mentioned. The analytical tool is the IWH signals approach. The study concludes that the risk of the outbreak of a financial crisis within the next 18 months is rather unrealistic in most countries. A stable economic policy, high real growth rates, a financial system already robust compared to earlier times of transition, and appropriate exchange rate arrangements protect the countries against speculative attacks and portfolio adjustments. When the composite indicator shows deterioration like in the Baltic countries, it turned out to be negligible. For the Slovak Republic and Slovenia, the composite indicator even improved. A closer look to individual indicators reveals still some problems in the banking sectors of the Czech Republic, Poland, and Hungary, however, without out major impact on the composite indicator.
This general assessment does not apply to Romania, and, in particular, to Turkey. The composite indicator signals a significant increase of the risk potential for the next 18 months in both countries. There is a considerable need for sound policy action.

Original Sin - Analysing Its Mechanics and a proposed Remedy in a Simple Macroeconomic Model
Axel Lindner
IWH Discussion Papers,
No. 11,
2006
Abstract
This paper analyses the problem of “original sin“ (the fact that the currency of an emerging market economy usually cannot be used to borrow abroad) in a simple thirdgeneration model of currency crises. The approach differs from alternative frameworks by explicitly modeling the price setting behavior of firms if prices are sticky and the future exchange rate is uncertain. Monetary policy optimally trades off effects on price competitiveness and on debt burdens of firms. It is shown that the proposal by Eichengreen and Hausmann of creating an artificial basket currency as denominator of debt is attractive as a provision against contagion.

Does Transparency of Central Banks produce Multiple Equilibria on Currency Markets?
Axel Lindner
Scandinavian Journal of Economics,
No. 1,
2006
Abstract
A recent strand of literature shows that multiple equilibria in models of markets for pegged currencies vanish if there is slightly diverse information among traders; see Morris and Shin (2001). It is known that this approach works only if the common knowledge in the market is not too precise. This has led to the conclusion that central banks should try to avoid making their information common knowledge. We develop a model in which more transparency of the central bank implies better private information, because each trader utilises public information according to her own private information. Thus, transparency makes multiple equilibria less likely.

Optimierung der Geldpolitik in Schwellenländern durch einen International-Lender-of-Last-Resort

Abstract
Current currency crises in emerging market economies show the insufficiency of preventive measures on national, regional and international level. The task of the book is therefore to analyze systematically which conditions monetary policy has to fulfill in order to prevent currency crises. In a first step optimal, crises-preventing monetary policy is modeled. Further the chances for overcoming the limitations of national policy are discussed on the regional and international level. The main result of the descriptive, theoretical and econometric analysis is the construction of an instrument for international monetary policy: the International Lender of Last Resort.

Optimale Geld- und Währungspolitik in Südafrika – Modellierung und Schätzung

Abstract
THE AIM OF THIS PAPER is to combine the estimation of the Monetary Conditions Index (MCI) with the theoretic modelling of monetary policy rules for open and emerging market economies using the example of South Africa. The idea that monetary policy is not only interested in optimal monetary conditions but also in external stability, constitutes the basis for the analysis. This idea emerged from studying currency crises that are caused by inadequate monetary policy and in particular from the experience of the Asian crisis of 1997/98 and its worldwide spread also to South Africa. The Monetary Conditions Index is a potentially useful tool for the development of monetary policy rules.

IWH early warning indicators for financial crises in Central and Eastern Europe: Risk potential remains low
Ibolya Mile
Wirtschaft im Wandel,
No. 8,
2003
Abstract
Die aktuelle Analyse der Frühwarnindikatoren des IWH signalisiert ein weiterhin geringes Risiko für den Ausbruch von Finanzkrisen in den mittel- und osteuropäischen Beitrittsländern. Die Berechnungen bestätigen die positiven Erwartungen über die Stabilität der Finanzmärkte in dieser Region, die sich bereits in der vorangegangenen Untersuchung angedeutet hatten. Doch in einigen Bereichen, wie auf dem fiskalischen Gebiet, besteht für die Mehrzahl der Länder weiterhin wirtschaftspolitischer Handlungsbedarf. Im März 2003 hat auch Kroatien einen Beitrittsantrag an die Europäische Kommission gestellt. Deshalb wurde Kroatien erstmalig mit in die Untersuchungen des IWH zur Bestimmung von Risikopotenzialen für Finanzkrisen einbezogen. Die Frühwarnindikatoren zeigen hier ein ähnliches Muster wie das der anderen mittel- und osteuropäischen Staaten.

Empirical methods for analysising the risks of financial crises
Axel Brüggemann, Thomas Linne
IWH-Sonderhefte,
No. 3,
2003
Abstract
he vulnerability against financial crises of EU candidate countries and other Central and East European countries is on the agenda of the Institute for Economic Research Halle. Research concentrates on the developing of effective early warning indicators and includes a strong orientation on quantitative methods. This volume presents selected methods for the analyse of financial fragility. The finding complete the signals approach, which is used by the IWH for routine checks of the risk potential of EU candidate an other countries of the region. The four studies presented here were written by the scientific staff of the IWH and by guest researchers. Their objective is to deepen insights into selected problems of financial fragility by using alternative methods.
