Optimum Currency Areas in Emerging Market Regions: Evidence Based on the Symmetry of Economic Shocks

Open Economies Review,
No. 5,

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.

What Might Central Banks Lose or Gain in Case of Euro Adoption – A GARCH-Analysis of Money Market Rates for Sweden, Denmark and the UK
Herbert S. Buscher, Hubert Gabrisch
IWH Discussion Papers,
No. 9,
2011
Abstract
This study deals with the question whether the central banks of Sweden, Denmark and the UK can really influence short-term money markets and thus, would lose this influence in case of Euro adoption. We use a GARCH-M-GED model with daily money market rates. The model reveals the co-movement between the Euribor and the shortterm interest rates in these three countries. A high degree of co-movement might be seen as an argument for a weak impact of the central bank on its money markets. But this argument might only hold for tranquil times. Our approach reveals, in addition, whether there is a specific reaction of the money markets in turbulent times. Our finding is that the policy of the European Central Bank (ECB) has indeed a significant impact on the three money market rates, and there is no specific benefit for these countries to stay outside the Euro area. However, the GARCH-M-GED model further reveals risk divergence and unstable volatilities of risk in the case of adverse monetary shocks to the economy for Sweden and Denmark, compared to the Euro area. We conclude that the danger of adverse monetary developments cannot be addressed by a common monetary
policy for these both countries, and this can be seen as an argument to stay outside the Euro area

What Can Currency Crisis Models Tell Us about the Risk of Withdrawal from the EMU? Evidence from ADR Data
Stefan Eichler
Journal of Common Market Studies,
No. 4,
2011
Abstract
We study whether ADR (American depositary receipt) investors perceive the risk that countries such as Greece, Ireland, Italy, Portugal or Spain could leave the eurozone to address financial problems produced by the sub-prime crisis. Using daily data, we analyse the impact of vulnerability measures related to currency crisis theories on ADR returns. We find that ADR returns fall when yield spreads of sovereign bonds or CDSs (credit default swaps) rise (i.e. when debt crisis risk increases); when banks' CDS premiums rise or stock returns fall (i.e. when banking crisis risk increases); or when the euro's overvaluation increases (i.e. when the risk of competitive devaluation increases).

Macroeconomic Challenges in the Euro Area and the Acceding Countries
Katja Drechsel
Dissertation, Online-Publikation,
2010
Abstract
The conduct of effective economic policy faces a multiplicity of macroeconomic challenges, which requires a wide scope of theoretical and empirical analyses. With a focus on the European Union, this doctoral dissertation consists of two parts which make empirical and methodological contributions to the literature on forecasting real economic activity and on the analysis of business cycles in a boom-bust framework in the light of the EMU enlargement. In the first part, we tackle the problem of publication lags and analyse the role of the information flow in computing short-term forecasts up to one quarter ahead for the euro area GDP and its main components. A huge dataset of monthly indicators is used to estimate simple bridge equations. The individual forecasts are then pooled, using different weighting schemes. To take into consideration the release calendar of each indicator, six forecasts are compiled successively during the quarter. We find that the sequencing of information determines the weight allocated to each block of indicators, especially when the first month of hard data becomes available. This conclusion extends the findings of the recent literature. Moreover, when combining forecasts, two weighting schemes are found to outperform the equal weighting scheme in almost all cases. In the second part, we focus on the potential accession of the new EU Member States in Central and Eastern Europe to the euro area. In contrast to the discussion of Optimum Currency Areas, we follow a non-standard approach for the discussion on abandonment of national currencies the boom-bust theory. We analyse whether evidence for boom-bust cycles is given and draw conclusions whether these countries should join the EMU in the near future. Using a broad range of data sets and empirical methods we document credit market imperfections, comprising asymmetric financing opportunities across sectors, excess foreign currency liabilities and contract enforceability problems both at macro and micro level. Furthermore, we depart from the standard analysis of comovements of business cycles among countries and rather consider long-run and short-run comovements across sectors. While the results differ across countries, we find evidence for credit market imperfections in Central and Eastern Europe and different sectoral reactions to shocks. This gives favour for the assessment of the potential euro accession using this supplementary, non-standard approach.

Central Banks, Trade Unions and Reputation – Is there Room for an Expansionist Manoeuvre in the European Union?
Toralf Pusch, A. Heise
Journal of Post Keynesian Economics,
2010
Abstract
It is now a few years since the introduction of the common currency, and Europe is still experiencing high unemployment. The conventional logic attributes this problem to flaws in the labour market. In this article we look at the changes that occur if labour unions and the Central Bank have different options to choose from in a climate of uncertainty. In a single-stage game the most probable outcome is a high unemployment rate. Results change dramatically if the game is repeated. However, this effect does not occur if the Central Bank puts a too high weight on price stability. Secondly, if the trade unions do not possess the capability for coordinating and moderating their wage claims, a full employment equilibrium is out of range.

Interest Rate Convergence in the Euro-Candidate Countries: Volatility Dynamics of Sovereign Bond Yields
Hubert Gabrisch, Lucjan T. Orlowski
Emerging Markets Finance and Trade,
2010
Abstract
We argue that a “static“ specification of the Maastricht criterion for long-term bond yields is not conducive to assessing stability of financial systems in euro-candidate countries. Instead, we advocate a dynamic approach to assessing interest rate convergence to a common currency that is based on the analysis of financial system stability. Accordingly, we empirically test volatility dynamics of the ten-year sovereign bond yields of the 2004 EU accession countries in relation to the eurozone yields during the January 2, 2001-January 22, 2009, sample period. Our results show a varied degree of the relationship between domestic and eurozone sovereign bond yields, the most pronounced for the Czech Republic, Slovenia, and Poland, and weaker for Hungary and Slovakia. We find some divergence of relative bond yields since the EU accession.

Has the Euro Increased International Price Elasticities?
Oliver Holtemöller, Götz Zeddies
IWH Discussion Papers,
No. 18,
2010
published in: Empirica
Abstract
This paper analyzes the role of common data problems when identifying structural breaks in small samples. Most notably, we survey small sample properties of the most commonly applied endogenous break tests developed by Brown, Durbin, and Evans (1975) and Zeileis (2004), Nyblom (1989) and Hansen (1992), and Andrews, Lee, and Ploberger (1996). Power and size properties are derived using Monte Carlo simulations. Results emphasize that mostly the CUSUM type tests are affected by the presence of heteroscedasticity, whereas the individual parameter Nyblom test and AvgLM test are proved to be highly robust. However, each test is significantly affected by leptokurtosis. Contrarily to other tests, where skewness is far more problematic than kurtosis, it has no additional effect for any of the endogenous break tests we analyze. Concerning overall robustness the Nyblom test performs best, while being almost on par to more recently developed tests in terms of power.

Leistungsbilanzungleichgewichte in der EU – Eine Herausforderung für die europäische Fiskalpolitik?
Toralf Pusch
Wirtschaft im Wandel,
No. 5,
2010
Abstract
In the European Monetary Union there is an ongoing debate about the sustainability of high and long-lasting current account deficits and surpluses. In light of the questions of its proper working as a currency area and inspired by the Optimum Currency Area theory, economic policy proposals have been developed for the institutional amendment of European fiscal policy. This contribution questions if the existing proposals are suitable for addressing the problem of current account balances which are deemed to be excessive. Alternatives have to be developed with a symmetrical impact, thus targeting excessive current account deficits and surpluses as well. At the same time, a challenge for such an alternative would be a more effective implementation than the existing modes of European economic policy coordination.
