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.

Poland Weathers the Crisis

Wirtschaft im Wandel,
No. 12,
2009
Abstract
Expansion of economic activity in Poland in 2009 continued at a markedly lower level compared to previous years, but despite the falling external and domestic demand, economic recession did not happen until now. Early stabilisation measures, supported also by the European Community (EC) and the International Monetary Fund (IMF), helped to avoid substantial instabilities in the financial sector. It seems that Poland is not as hardly affected by the financial crisis as other countries. Unlike previous years, now net exports were the main driving force for growth – they more than compensated the decrease in domestic demand.
Unemployment had risen up from the lowest level in the last decade, but still moderately due to measures of job security. Given the further shrinking labour demand, unemployment will increase despite modest economic activity. Fiscal policy has to meet challenges under the current economic crises: Excess expenditure and deficiency in receipts will deteriorate general government deficit in 2009 and 2010. Without adopted consolidation strategy, Polish convergence to the Euro area will have to be postponed.

Is the European Monetary Union an Endogenous Currency Area? The Example of the Labor Markets
Herbert S. Buscher, Hubert Gabrisch
IWH Discussion Papers,
No. 7,
2009
Abstract
Our study tries to find out whether wage dynamics between Euro member countries became more synchronized through the adoption of the common currency. We calculate bivarate correlation coefficients of wage and wage cost dynamics and run a model of endogenously induced changes of coefficients, which are explained by other variables being also endogenous: trade intensity, sectoral specialization, financial integration. We used a panel data structure to allow for cross-section weights for country-pair observations. We use instrumental variable regressions in order to disentangle exogenous from endogenous influences. We applied these techniques to real and nominal wage dynamics and to dynamics of unit labor costs. We found evidence for persistent asymmetries in nominal wage formation despite a single currency and monetary policy, responsible for diverging unit labor costs and for emerging trade imbalances among the EMU member countries.

The New EU Members on the Verge of Disaster: What to Do?
Hubert Gabrisch
Wirtschaft im Wandel,
No. 3,
2009
Abstract
The long lasting, but externally financed boom in the new EU countries has collapsed under the impacts of the global financial crisis. The countries’ fiscal and monetary authorizes do not seem to be able to effectively resist – a deep crisis is under way. The situation is particularly dramatic in the Baltic countries, where the hands of the monetary authority are institutionally tied, and an expansionary fiscal policy would trigger off speculative attacks on the exchange rate. Neither the maintaining of the currency board arrangement nor an ‘emergency access’ to the Euro zone would help. The other non-Euro members of the Union still aim to adopt the Euro in the next future and, thus, are reluctant to give up the Maastricht criteria. The Euro countries Slovakia and Slovenia might face a major deterioration of their credit rating if governments would attempt to increase fiscal deficits. All in all, two problems are to be solved: first, the external provision of liquidity to their economies and, second, an approach that anchors policies in the countries against economic nationalism, which is a beggar-thy-neighbor policy. We propose a combination of a reformed exchange rate mechanism with a stability and solidarity fund for all countries. The former would help to avoid too strong depreciations and the latter would provide liquidity to stabilize the exchange rate and the entire economy.

Yes to Investments by Public Authorities for the Future! But Business Cycle will no Longer be Saved by it!

Wirtschaft im Wandel,
No. 3,
2009
Abstract
In order to mitigate the effects of the deep economic recession, the German federal government has adopted two economic stimulus packages to be applied in the period from 2009 to 2010. According to our estimations, these programs include investments amounting to 25.3 billion Euros mainly in infrastructure and education. We investigate the total effects of these investments on production and employment using a static input-output model. We find that the gross domestic product will increase by at most one percentage point, namely 0.4 points in 2009 and 0.7 points in 2010. This implies that approximately 400 000 jobs will be safeguarded. About one quarter of the effects will concern construction and business services respectively. For several reasons, our calculations constitute the upper bound to the expected effects. The increasing demand in construction could lead to significantly increasing prices. In light of the expected decline in production, the economic effects of the programs may appear to be low. Obviously, the strong decrease in external demand and its impact on the economy cannot be effectively combated by instruments of national economic policies.

Crisis Contagion in Central and Eastern Europe
Hubert Gabrisch
Wirtschaft im Wandel,
No. 12,
2008
Abstract
The global financial crisis reached the Central and Eastern European region. Fears of a recession are spreading among investors in Russia and the Ukraine due to the heavy decline of oil and steel prices and provoked a first wave of short-term capital withdrawals. The export sector of all countries in the region is affected by weakening global demand. Finally, the financial sector, which is dominated by international banks in almost all countries, appears as the contagion channel for risk adjustments of mother banks. The combined impact of all these causes and channels lead to a proliferation of restrictions in credit and money supply and an outflow of investment capital. A strong weakening of economic growth is on the way in the region, and a long-lasting recession seems possible in some countries, in first line in the Baltic countries. It becomes a superior task of governments to ease the length and depth of the approaching recession by a strong fiscal stimulus. A continuation of the present policy of fiscal consolidation or of nominal convergence toward a quick adoption of the Euro does not seem very advisable. If governments decided to support domestic demand, measures should be taken to strengthening of a genuinely domestic banking sector in order to maintain credit availability.

Money and Credit Market Integration in an enlarging Euro Zone: Methodological Issues
Johannes Stephan, Jens Hölscher
European Economic Policies - Alteratives to Orthodox Analysis and Policy Concepts,
2006
Abstract
“The chapter discusses methodological issues of money and credit market integration within the context of an enlarging Euro area. Common methods of interest parity tests are rejected in favour of a comparison of nominal interest rates. Hölscher and Stephan find that from an institutional point of view the new EU member countries look under-banked, whereas interest rates are converging. As policy implication the paper argues for a Euro adoption of the new EU members rather sooner than later.“
