Optimum Currency Areas in Emerging Market Regions: Evidence Based on the Symmetry of Economic Shocks
Stefan Eichler, Alexander Karmann
Open Economies Review,
No. 5,
2011
Abstract
This paper examines which emerging market regions form optimum currency areas (OCAs) by assessing the symmetry of macroeconomic shocks. We extend the output-prices-VAR framework by adding net exports and the real effective exchange rate as endogenous variables. Based on theoretical considerations, we derive which shocks affect these variables in the long run: shocks to labor productivity, foreign trade, labor supply, and money supply. The considered economies of Central and Eastern Europe, the Commonwealth of Independent States, East and Southeast Asia, and South Asia, exhibit large enough shock symmetry to form a currency union; the economies of Africa, Latin America, and the Middle East do not.

Exit Expectations and Debt Crises in Currency Unions
Alexander Kriwoluzky, G. J. Müller, M. Wolf
IWH Discussion Papers,
No. 18,
2015
Abstract
Membership in a currency union is not irreversible. Exit expectations may emerge during sovereign debt crises, because exit allows countries to reduce their liabilities through a currency redenomination. As market participants anticipate this possibility, sovereign debt crises intensify. We establish this formally within a small open economy model of changing policy regimes. The model permits explosive dynamics of debt and sovereign yields inside currency unions and allows us to distinguish between exit expectations and those of an outright default. By estimating the model on Greek data, we quantify the contribution of exit expectations to the crisis dynamics during 2009 to 2012.

Implementing an International Lender of Last Resort
Tobias Knedlik
IWH Discussion Papers,
No. 20,
2006
Abstract
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.

The ADR Shadow Exchange Rate as an Early Warning Indicator for Currency Crises
Stefan Eichler, Alexander Karmann, Dominik Maltritz
Journal of Banking and Finance,
No. 11,
2009
Abstract
We develop an indicator for currency crisis risk using price spreads between American Depositary Receipts (ADRs) and their underlyings. This risk measure represents the mean exchange rate ADR investors expect after a potential currency crisis or realignment. It makes crisis prediction possible on a daily basis as depreciation expectations are reflected in ADR market prices. Using daily data, we analyze the impact of several risk drivers related to standard currency crisis theories and find that ADR investors perceive higher currency crisis risk when export commodity prices fall, trading partners’ currencies depreciate, sovereign yield spreads increase, or interest rate spreads widen.

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.

Signaling Currency Crises in South Africa
Tobias Knedlik
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.

Signaling currency crises in South Africa

South African Reserve Bank: Macroeconomic Policy Challenges for South Africa Conference, South African Reserve Bank,
2006
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.

Three methods of forecasting currency crises: Which made the run in signaling the South African currency crisis of June 2006?
Tobias Knedlik, Rolf Scheufele
IWH Discussion Papers,
No. 17,
2007
Abstract
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.
