25 Jahre nach dem Mauerfall: Wirtschaftliche Integration Ostdeutschlands im Spiegel der Forschung am IWH
One-off Publications,
2014
Abstract
Als vor 25 Jahren die Berliner Mauer fiel, gewannen die Bürger der DDR ihre bürgerlichen Freiheiten zurück. Sie können seitdem frei reisen und ihren Wohn- und Arbeitsort frei wählen. Auf den Mauerfall folgten in historisch einmaligem Tempo Weichenstellungen zur Deutschen Einheit: erste freie Volkskammerwahlen am 18.03.1990, die Wirtschafts-, Währungs- und Sozialunion am 01.07.1990 und schließlich die Einheit Deutschlands durch den Beitritt der DDR zum Geltungsbereich des Grundgesetzes der Bundesrepublik Deutschland. Die Integration der ost- und westdeutschen Wirtschaft ist allerdings ein langwieriger Prozess.

The Development of Cities and Municipalities in Central and Eastern Europe: Introduction for a Special Issue of 'Urban Research and Practice'
Martin T. W. Rosenfeld, Albrecht Kauffmann
Urban Research & Practice, Vol. 7 (3),
No. 3,
2014
Abstract
Since the 1990s, local governments in Central and Eastern European (CEE) countries have been confronted by completely new structures and developments. This came after more than 40 years (or even longer in the case of the former Soviet Union) under a socialist regime and behind an iron curtain which isolated them from the non-socialist world. A lack of resources had led to an underinvestment in the refurbishment of older buildings, while relatively cheap ‘prefabricated’ housing had been built, not only in the outskirts of cities, but also within city centres. A lack of resources had also resulted in the fact that the socialist regimes were generally unable to replace old buildings with ‘modern’ ones; hence, there is a very rich heritage of historical monuments in many of these cities today. The centrally planned economies and the development of urban structures (including the shifts of population between cities and regions) were determined by ideology, political rationality and the integration of all CEE countries into the production schemes of the Council for Mutual Economic Assistance and its division of labour by location. The sudden introduction of a market economy, private property, democratic rules, local autonomy for cities and municipalities and access to the global economy and society may be seen as a kind of ‘natural experiment’. How would these new conditions shape the national systems of cities and municipalities? Which cities would shrink and which would grow? How would the relationship between core cities and their surrounding municipalities develop? And what would happen within these cities and with their built environment?

Do We Need New Modelling Approaches in Macroeconomics?
Claudia M. Buch, Oliver Holtemöller
IWH Discussion Papers,
No. 8,
2014
Abstract
The economic and financial crisis that emerged in 2008 also initiated an intense discussion on macroeconomic research and the role of economists in society. The debate focuses on three main issues. Firstly, it is argued that economists failed to predict the crisis and to design early warning systems. Secondly, it is claimed that economists use models of the macroeconomy which fail to integrate financial markets and which are inadequate to model large economic crises. Thirdly, the issue has been raised that economists invoke unrealistic assumptions concerning human behaviour by assuming that all agents are self-centred, rationally optimizing individuals. In this paper, we focus on the first two issues. Overall, our thrust is that the above statements are a caricature of modern economic theory and empirics. A rich field of research developed already before the crisis and picked up shortcomings of previous models.

Has Labor Income Become More Volatile? Evidence from International Industry-Level Data
Claudia M. Buch
German Economic Review,
No. 4,
2013
Abstract
Changes in labor market institutions and the increasing integration of the world economy may affect the volatility of capital and labor incomes. This article documents and analyzes changes in income volatility using data for 11 industrialized countries, 22 industries and 35 years (1970–2004). The article has four main findings. First, the unconditional volatility of labor income has declined in parallel to the decline in macroeconomic volatility. Second, the industry-specific, idiosyncratic component of labor income volatility has hardly changed. Third, cross-sectional heterogeneity is substantial. If anything, the labor incomes of high- and low-skilled workers have become more volatile relative to the volatility of capital incomes. Fourth, the volatility of labor income relative to the volatility of capital income declines in the labor share. Trade openness has no clear-cut impact.

Towards Deeper Financial Integration in Europe: What the Banking Union Can Contribute
Claudia M. Buch, T. Körner, Benjamin Weigert
IWH Discussion Papers,
No. 13,
2013
Abstract
The agreement to establish a Single Supervisory Mechanism in Europe is a major step towards a Banking Union, consisting of centralized powers for the supervision of banks, the restructuring and resolution of distressed banks, and a common deposit insurance system. In this paper, we argue that the Banking Union is a necessary complement to the common currency and the Internal Market for capital. However, due care needs to be taken that steps towards a Banking Union are taken in the right sequence and that liability and control remain at the same level throughout. The following elements are important. First, establishing a Single Supervisory Mechanism under the roof of the ECB and within the framework of the current EU treaties does not ensure a sufficient degree of independence of supervision and monetary policy. Second, a European institution for the restructuring and resolution of banks should be established and equipped with sufficient powers. Third, a fiscal backstop for bank restructuring is needed. The ESM can play a role but additional fiscal burden sharing agreements are needed. Direct recapitalization of banks through the ESM should not be possible until legacy assets on banks’ balance sheets have been cleaned up. Fourth, introducing European-wide deposit insurance in the current situation would entail the mutualisation of legacy assets, thus contributing to moral hazard.

Towards a Europeanization of Wage Bargaining? Evidence from the Metal Sector
Vera Glassner, Toralf Pusch
European Journal of Industrial Relations,
No. 2,
2013
Abstract
European trade unions have attempted to coordinate their bargaining strategies transnationally in order to counter downward pressures on wages. Such coordination is most feasible in broadly integrated and exposed sectors that have to face common competitive constraints on wages. This article investigates collectively negotiated wage increases in the metal sector in Belgium, the Netherlands and Germany. We assume a specific logic of transnational pattern bargaining, with Germany as the ‘anchor’ country. We investigate the emergence of a transnational wage coordination effect before and after institutions for the coordination of wage bargaining were established. Finally, we draw conclusions on prospects for wage bargaining coordination with further integration of Economic and Monetary Union.

Consumption Volatility and Financial Openness
Claudia M. Buch, S. Yener
Applied Economics,
2010
Abstract
Economic theory predicts that the integration of financial markets lowers the volatility of consumption. In this article, we study long-term trends in the consumption volatility of the G7 countries. Using different measures of financial openness, we find evidence that greater financial openness has been associated with lower consumption volatility. However, volatility of consumption relative to output has not declined.

Sovereign Credit Risk Co-movements in the Eurozone: Simple Interdependence or Contagion?
Manuel Buchholz, Lena Tonzer
UniCredit & Universities Foundation, Working Paper Series No. 47,
No. 47,
2013
published in: International Finance
Abstract
We investigate credit risk co-movements and contagion in sovereign debt markets of 17 industrialized countries for the period 2008-2012. We use dynamic conditional correlations of sovereign CDS spreads to detect contagion. This approach allows separating the channels through which contagion occurs from the determinants of simple interdependence. The results show that, first, sovereign credit risk comoves considerably, in particular among eurozone countries and during the sovereign debt crisis. Second, contagion cannot be attributed to one moment in time but varies across time and countries. Third, similarities in economic fundamentals, cross-country linkages in banking, and common market sentiment constitute the main channels of contagion.
