IWH Discussion Papers,
No. 19,
2006
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.

Abstract
Diese Arbeit betrachtet die südafrikanischen Währungskrisenepisoden von 1996, 1998 und 2001, um gemeinsame länderspezifische Ursachen für Währungskrisen in Südafrika zu ermitteln. Die Identifikation der Währungskrisen erfolgt mittels des Exchange Market Pressure Indexes, welcher von Eichengreen, Rose und Wyplosz (1996) entwickelt wurde. Dann wird ein Signalansatz, basierend auf Kaminsky und Reinhart (1996, 1998) verwendet, um mit dessen Hilfe das Risiko für Währungskrisen in Südafrika zu evaluieren. Die Arbeit berücksichtigt als potentielle Einflussgrößen die üblichen Variablen aus der Währungskrisentheorie sowie länderspezifische Faktoren, welche sich aus dem Bericht der Myburgh Commission (2002) und aktueller Literatur ergeben.

Are Botswana and Mozambique ready for CMA enlargement?
Tobias Knedlik
Botswana Journal of Economics,
No. 3,
2006
Abstract
The paper elaborates on the appropriateness of a potentially enlarged Common Monetary Area in Southern Africa including Botswana and Mozambique. The theory of optimum currency areas including some extensions by accounting for costs of non-integration and considering the external relations of currency areas are presented. Various indicators such as the structure of the economies, interest rates, inflation rates, exchange rates, factor mobility and trading partners are observed empirically. The paper concludes that current changes in the exchange rate policy of Botswana are expected to lead to increasing, though already high, convergence with CMA countries. Botswana is therefore an appropriate candidate for CMA enlargement. Mozambique is converging towards South Africa but still remains on a lower level. Taking into account the costs of non-integration, however, the target of integration should be formulated for the medium term.

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.

Optimierung der Geldpolitik in Schwellenländern durch einen International-Lender-of-Last-Resort
Tobias Knedlik
Europäische Hochschulschriften, Reihe 5 Volks- und Betriebswirtschaft, Band 3202,
2006
Abstract
Aktuelle Währungskrisen in Schwellenländern zeigen, dass die präventiven Maßnahmen auf nationaler, regionaler und internationaler Ebene unzureichend sind. Diese Arbeit untersucht deshalb systematisch, welche Bedingungen die Geld- und Währungspolitik erfüllen muss, um Währungskrisen zu verhindern. Dazu wird zunächst auf nationaler Ebene eine optimale Geld- und Währungspolitik modelliert, die Krisen entgegenwirkt. Die Überwindbarkeit der Begrenztheit nationaler Politik wird dann auf regionaler und internationaler Ebene diskutiert. Dabei ist die Entwicklung eines Instruments der internationalen Geld- und Währungspolitik zur Unterstützung von Schwellenländern das Hauptergebnis der deskriptiven, theoretischen und ökonometrischen Analysen dieser Arbeit: der International-Lender-of-Last-Resort.

Determinants of employment - the macroeconomic view
Christian Dreger, Heinz P. Galler, Ulrich (eds) Walwai
Schriften des IWH,
No. 22,
2005
Abstract
The weak performance of the German labour market over the past years has led to a significant unemployment problem. Currently, on average 4.5 mio. people are without a job contract, and a large part of them are long-term unemployed. A longer period of unemployment reduces their employability and aggravates the problem of social exclusion.
The factors driving the evolution of employment have been recently discussed on the workshop Determinanten der Beschäftigung – die makroökonomische Sicht organized jointly by the IAB, Nuremberg, and the IWH, Halle. The present volume contains the papers and proceedings to the policy oriented workshop held in November 2004, 15-16th. The main focus of the contributions is twofold. First, macroeconomic conditions to stimulate output and employment are considered. Second, the impacts of the increasing tax wedge between labour costs and the take home pay are emphasized. In particular, the role of the contributions to the social security system is investigated.
In his introductory address, Ulrich Walwei (IAB) links the unemployment experience to the modest path of economic growth in Germany. In addition, the low employment intensity of GDP growth and the temporary standstill of the convergence process of the East German economy have contributed to the weak labour market performance. In his analysis, Gebhard Flaig (ifo Institute, München) stresses the importance of relative factor price developments. A higher rate of wage growth leads to a decrease of the employment intensity of production, and correspondingly to an increase of the threshold of employment. Christian Dreger (IWH) discusses the relevance of labour market institutions like employment protection legislation and the structure of the wage bargaining process on the labour market outcome. Compared to the current setting, policies should try to introduce more flexibility in labour markets to improve the employment record. The impact of interest rate shocks on production is examined by the paper of Boris Hofmann (Deutsche Bundesbank, Frankfurt). According to the empirical evidence, monetary policy cannot explain the modest economic performance in Germany. György Barabas and Roland Döhrn (RWI Essen) have simulated the effects of a world trade shock on output and employment. The relationships have been fairly stable over the past years, even in light of the increasing globalization. Income and employment effects of the German tax reform in 2000 are discussed by Peter Haan and Viktor Steiner (DIW Berlin). On the base of a microsimulation model, household gains are determined. Also, a positive relationship between wages and labour supply can be established. Michael Feil und Gerd Zika (IAB) have examined the employment effects of a reduction of the contribution rates to the social security system. To obtain robust results, the analysis is done under alternative financing scenarios and with different macroeconometric models. The impacts of allowances of social security contributions on the incentives to work are discussed by Wolfgang Meister and Wolfgang Ochel (ifo München). According to their study, willingness to work is expected to increase especially at the lower end of the income distribution. The implied loss of contributions could be financed by higher taxes.

Optimale Geld- und Währungspolitik in Südafrika – Modellierung und Schätzung
Tobias Knedlik
Berichte der Internationalen Wissenschaftliche Vereinigung Weltwirtschaft und Weltpolitik e.V. Vol. 15,
No. 161,
2005
Abstract
Ziel des Beitrags ist die Modellierung von Politikregeln für die Geldpolitik in Südafrika. Grundlegend ist die Idee, dass die Geldpolitik nicht nur an optimalen monetären Bedingungen im Inland interessiert sein sollte, sondern gleichzeitig für externe Stabilität - Verhinderung von Währungskrisen - sorgen müsste. Ein Instrument zur Ableitung von Politikregeln ist der Monetary Conditions Index. Auf die Darstellung und Schätzung des Indizes wird zuerst eingegangen. Aufbauend darauf werden dann Regeln abgeleitet, die in dem definierten Modellrahmen zu optimalen geldpolitischen Ergebnissen führen. Dieser theoretischen Diskussion schließt sich die auf empirischen Schätzungen basierende Konkretisierung der Regeln für das Beispielland Südafrika an.

Business Cycle Volatility in Germany
Claudia M. Buch, J. Doepke, C. Pierdzioch
German Economic Review,
2004
Abstract
Stylized facts suggest that output volatility in OECD countries has declined in recent years. The causes and the nature of this decline have so far been analyzed mainly for the United States. In this paper, we analyze whether structural changes in output volatility in Germany can be detected. We report evidence that output volatility has declined in Germany. It is difficult to answer the question whether this decline in output volatility reflects good economic and monetary policy or merely ‘good luck’.
