Predicting Financial Crises: The (Statistical) Significance of the Signals Approach
Makram El-Shagi, Tobias Knedlik, Gregor von Schweinitz
Abstract
The signals approach as an early warning system has been fairly successful in detecting crises, but it has so far failed to gain popularity in the scientific community because it does not distinguish between randomly achieved in-sample fit and true predictive power. To overcome this obstacle, we test the null hypothesis of no correlation between indicators and crisis probability in three applications of the signals approach to different crisis types. To that end, we propose bootstraps specifically tailored to the characteristics of the respective datasets. We find (1) that previous applications of the signals approach yield economically meaningful and statistically significant results and (2) that composite
indicators aggregating information contained in individual indicators add value to the signals approach, even where most individual indicators are not statistically significant on their own.

Macroeconomic Imbalances as Indicators for Debt Crises in Europe
Tobias Knedlik, Gregor von Schweinitz
Abstract
European authorities and scholars published proposals on which indicators of macroeconomic imbalances might be used to uncover risks for the sustainability of public debt in the European Union. We test the ability of four proposed sets of indicators to send early-warnings of debt crises using a signals approach for the study of indicators and the construction of composite indicators. We find that a broad composite indicator has the highest predictive power. This fact still holds true if equal weights are used for the construction of the composite indicator in order to reflect the uncertainty about the origin of future crises.

The ADR Shadow Exchange Rate as an Early Warning Indicator for Currency Crises
Stefan Eichler, Alexander Karmann, Dominik Maltritz
Journal of Banking and Finance,
Nr. 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.

Empirical methods for analysising the risks of financial crises
Axel Brüggemann, Thomas Linne
IWH-Sonderhefte,
Nr. 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.

Recent Developments and Risks in the Euro Area Banking Sector
Reint E. Gropp, Jukka M. Vesala
ECB Monthly Bulletin,
2002
Abstract
This article provides an overview of euro area banks’ exposure to risk and examines the effects of the cyclical downturn in 2001. It describes the extent to which euro area banks’ risk profile has changed as a result of recent structural developments, such as an increase in investment banking, mergers, securitisation and more sophisticated risk management techniques. The article stresses that the environment in which banks operated in 2001 was fairly complex due to the relatively weak economic performance of all major economies as well as the events of 11 September in the United States. It evaluates the effects of these adverse circumstances on banks’ stability and overall performance. The article provides bank balance sheet information as well as financial market prices, arguing that the latter may be useful when assessing the soundness of the banking sector in a forward-looking manner. It concludes with a review of the overall stability of euro area banks, pointing to robustness in the face of the adverse developments in 2001 and the somewhat improved forward-looking indicators of banks’ financial strength in early 2002.
