Abstract
The most recent economic downturn has shown that economic activity nowadays is still prone to large fluctuations. Despite a long tradition of research, the understanding of such fluctuations, namely business cycles, is still far from comprehensive. Moreover, in a developing world with new technologies, faster communication systems, a higher integration of world markets and increasingly better-skilled people the nature of business cycles changes continuously and new insights can be drawn from recent experience.

Returning to East Germany: Labour Market Success Reduces Re-migration Potential
D. Wiest, Lutz Schneider, Alexander Kubis
Wirtschaft im Wandel,
No. 9,
2009
Abstract
Die Abwanderung überwiegend junger gebildeter Menschen aus Ostdeutschland wird häufig, vor allem vor dem Hintergrund der bedenklichen demographischen Entwicklung, als nachteilig für die Entwicklungsfähigkeit und den Aufholprozess der Neuen Länder betrachtet. Das Phänomen der Zuwanderung und dabei nicht zuletzt der Rückwanderung vormals Abgewanderter fand in diesem Zusammenhang bisher vergleichsweise wenig Beachtung, obwohl einiges darauf hindeutet, dass hierin das eigentliche Migrationsproblem Ostdeutschlands liegt.
Die vorliegende Arbeit analysiert auf Basis eines im Rahmen des DFG-Forschungsprojektes „Brain drain aus Ostdeutschland“ am Lehrstuhl für Sozialgeographie der Martin-Luther-Universität Halle-Wittenberg erhobenen Datensatzes zu den Einstellungen und Motivlagen aus Sachsen-Anhalt abgewanderter junger Menschen, welche Faktoren die Neigung zu einer Rückkehr nach Sachsen-Anhalt erklären. Dabei wird auf zwei Aspekte besonderer Wert gelegt: erstens auf die Wirkung des Arbeitsmarkterfolges nach der Abwanderung, zweitens auf den Einfluss sozialer Bindungen in der Herkunfts- und der Zielregion auf die Rückkehrbereitschaft der abgewanderten Menschen.
Im Ergebnis bestätigt die ökonometrische Analyse des Rückkehrpotenzials die aus der Theorie heraus erwarteten Wirkungsrichtungen der untersuchten Einflussgrößen. Zum einen dämpft der individuelle Arbeitsmarkterfolg in der Zielregion die Rückkehrneigung, was im Umkehrschluss eine „Negativselektion“ bzw. eine erhöhte Rückkehrbereitschaft derer bedeutet, deren Erwartungen an die Zielregion enttäuscht wurden. Zum anderen konnte die rückwanderungsfördernde Wirkung bestehender sozialer Bindungen zum Herkunftsgebiet nachgewiesen werden.

Openness and Growth: The Long Shadow of the Berlin Wall
Claudia M. Buch, Farid Toubal
Journal of Macroeconomics,
No. 3,
2009
Abstract
The question whether international openness causes higher domestic growth has been subject to intense discussions in the empirical growth literature. This paper addresses the issue in the context of the fall of the Berlin Wall in 1989. We analyze whether the slow convergence in per capita incomes between East and West Germany and the lower international openness of East Germany are linked. We address the endogeneity of openness by adapting the methodology proposed by Frankel and Romer (1999) to a panel framework. We instrument openness with time-invariant exogenous geographic variables and time-varying exogenous policy variables. We also distinguish the impact of different channels of integration. Our paper has three main findings. First, geographic variables have a significant impact on regional openness. Second, controlling for geography, East German states are less integrated into international markets along all dimensions of integration considered. Third, the degree of openness for trade has a positive impact on regional income per capita.

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.

Banking Integration, Bank Stability, and Regulation: Introduction to a Special Issue of the International Journal of Central Banking
Reint E. Gropp, H. Shin
International Journal of Central Banking,
No. 1,
2009
Abstract
The link between banking integration and financial stability has taken center stage in the wake of the current financial crisis. To what extent is the banking system in Europe integrated? What role has the introduction of the common currency played in this context? Are integrated banking markets more vulnerable to contagion and financial instability? Does the fragmented regulatory framework in Europe pose special problems in resolving bank failures? What policy reforms may become necessary? These questions are of considerable policy interest as evidenced by the extensive discussions surrounding the design and implementation of a new regulatory regime and by the increasing attention coming from academia.

The Euro and the Competitiveness of European Firms
Filippo di Mauro, Gianmarco Ottaviano, Daria Taglioni
Economic Policy,
No. 57,
2009
Abstract
Much attention has been paid to the impact of a single currency on actual trade volumes. Lower trade costs, however, matter over and beyond their effects on trade flows: as less productive firms are forced out of business by the tougher competitive conditions of international markets, economic integration fosters lower prices and higher average productivity. We assess the quantitative relevance of these effects calibrating a general equilibrium model using country, sector and firm-level empirical observations. The euro turns out to have increased the overall competitiveness of Eurozone firms, and the effects differ along interesting dimensions: they tend to be stronger for countries which are smaller or with better access to foreign markets, and for firms which specialize in sectors where international competition is fiercer and barriers to entry lower.— Gianmarco I.P.

Growth, Volatility, and Credit Market Imperfections: Evidence from German Firms
Claudia M. Buch, Jörg Döpke
Journal of Economic Studies,
2008
Abstract
Purpose – The purpose of this paper is two-fold. First, it studies whether output volatility and growth are linked at the firm-level, using data for German firms. Second, it explores whether the link between volatility and growth depends on the degree of credit market imperfections.
Design/methodology/approach – The authors use a novel firm-level dataset provided by the Deutsche Bundesbank, the so-called Financial Statements Data Pool. The dataset has time series observations for German firms for the period 1997-2004, and the authors use information on the debt-to-assets or leverage ratio of firms to proxy for credit-constraints at the firm-level. As additional proxies for the importance of credit market imperfections, we use information on the size and on the legal status of firms.
Findings – The authors find that higher volatility has a negative impact on growth for small and a positive impact for larger firms. Higher leverage is associated with higher growth. At the same time, there is heterogeneity in the determinants of growth across firms from different sectors and across firms with a different legal status.
Practical implications – While most traditional macroeconomic models assume that growth and volatility are uncorrelated, a number of microeconomic models suggest that the two may be linked. However, it is unclear whether the link is positive or negative. The paper presents additional evidence regarding this question. Moreover, understanding whether credit market conditions affect the link between volatility and growth is of importance for policy makers since it suggests a channel through which the credit market can have long-run welfare implications. The results stress the importance of firm-level heterogeneity for the effects and effectiveness of economic policy measures.
Originality/value – The paper has two main novel features. First, it uses a novel firm-level dataset to analyze the determinants of firm-level growth. Second, it analyzes the growth-volatility nexus using firm-level data. To the best of the authors' knowledge, this is the first paper, which addresses the link between volatility, growth, and credit market imperfections using firm-level data.

The Great Risk Shift? Income Volatility in an International Perspective
Claudia M. Buch
CESifo Working Paper No. 2465,
2008
Abstract
Weakening bargaining power of unions and the increasing integration of the world economy may affect the volatility of capital and labor incomes. This paper documents and explains changes in income volatility. Using a theoretical framework which builds distribution risk into a real business cycle model, hypotheses on the determinants of the relative volatility of capital and labor are derived. The model is tested using industry-level data. The data cover 11 industrialized countries, 22 manufacturing and services industries, and a maximum of 35 years. The paper has four main findings. First, the unconditional volatility of labor and capital incomes has declined, reflecting the decline in macroeconomic volatility. Second, the idiosyncratic component of income volatility has hardly changed over time. Third, crosssectional heterogeneity in the evolution of relative income volatilities is substantial. If anything, the labor incomes of high- and low-skilled workers have become more volatile in relative terms. Fourth, income volatility is related to variables measuring the bargaining power of workers. Trade openness has no significant impact.

Globalisation and the Competitiveness of the Euro Area
Filippo di Mauro, Katrin Forster
ECB Occasional Paper Series,
No. 97,
2008
Abstract
Against the background of increasing competition and other significant structural changes implied by globalisation, maintaining and enhancing competitiveness has evolved into one of the prime concerns in most countries. Following up on previous work (see in particular ECB Occasional Papers No. 30 and No. 55), this Occasional Paper examines the latest developments and prospects for the competitiveness and trade performance of the euro area and the euro area countries. Starting from an analysis of most commonly used, traditional competitiveness indicators, the paper largely confirms the findings of previous studies that there have been substantial adjustments in euro area trade. Euro area firms have taken advantage of the new opportunities offered by globalisation, and have at the same time been increasingly challenged by emerging economies. This is primarily reflected in the loss of export market shares which have been recorded over the last decade. While these can partly be related to the losses in the euro area's price competitiveness, further adjustment also seems warranted with regard to the export specialisation. Compared with other advanced competitors, the euro area remains relatively more specialised in labour intensive categories of goods and has shown only a few signs of a stronger specialisation in research-intensive goods. Nevertheless, the paper generally calls for a more cautious approach when assessing the prospects for euro area competitiveness, as globalisation has made it increasingly difficult to define and measure competitiveness. Stressing the need to take a broader view on competitiveness, specifically with a stronger emphasis on productivity performance, the paper also introduces a more elaborate framework that takes into account the interactions between country-specific factors and firm-level productivity. It thus makes it possible to construct more broadly defined competitiveness measures. Pointing to four key factors determining the global competitiveness of euro area countries - market accessibility, market size, technological leadership of firms and institutional set-up - the analysis provides further arguments for continuing efforts to increase market integration and strengthen the competitive environment within Europe as a mean of enhancing resource allocation and coping with the challenges globalisation creates.
