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.

FDI Micro Database – Methodological Note – Survey 2013 in East Germany and Selected CEE Countries
Andrea Gauselmann, Björn Jindra, Philipp Marek
Einzelveröffentlichungen,
2013
Abstract
With the integration of post-communist countries into the European and global economy
after 1990, there was strong research interest into the role of multinational enterprises
(MNEs) for economic restructuring and technological catching-up. Most of the existing
empirical studies on locational determinants of FDI and host country effects did not take
account of East Germany. This might be for different reasons: Firstly, theoretical and
empirical difficulties derive from the fact that East Germany followed a distinct transition
pattern as it became a region subsumed in a larger and more mature economy. Secondly,
East Germany received private investment from foreign as well as West German firms. Only
the first can be considered as a foreign direct investment (FDI). Finally, there had long been
a lack of micro data to adequately analyse the activities of corresponding firms from a
production as well as technological perspective.

Von der Transformation zur europäischen Integration
Der Prozess der ökonomischen Transformation in den ehemals sozialistischen Staaten gilt mittlerweile als abgeschlossen. Aber wie stark sind die Post-Transformationsökonomien in Ostdeutschland und Mittelosteuropa wirklich und wie lässt sich deren Wettbewerbsfähigkeit weiter entwickeln? Auf der Tagung „Von der Transformation zur europäischen Integration – Ostdeutschland und Mittelosteuropa in der Forschung des IWH“ widmet sich das IWH diesen Fragen und beleuchtet sie in ihrem Zusammenhang mit dem Prozess der europäischen Integration.

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.

The Social Capital Legacy of Communism-results from the Berlin Wall Experiment
Peter Bönisch, Lutz Schneider
European Journal of Political Economy,
No. 32,
2013
Abstract
In this paper we establish a direct link between the communist history, the resulting structure of social capital, and attitudes toward spatial mobility. We argue that the communist regime induced a specific social capital mix that discouraged geographic mobility even after its demise. Theoretically, we integrate two branches of the social capital literature into one more comprehensive framework distinguishing an open type and a closed type of social capital. Using the German Socio-Economic Panel (GSOEP) we take advantage of the natural experiment that separated Germany into two parts after the WWII to identify the causal effect of social capital on mobility. We estimate a three equation ordered probit model and provide strong empirical evidence for our theoretical propositions.
