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.

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.

Aktuelle Trends: Brain Gain und Brain Drain: Hochschul-Bildungswanderung im föderalen Deutschland
Marco Sunder, Dirk Trocka, Jutta Günther
Wirtschaft im Wandel,
No. 10,
2008
Abstract
Hochqualifizierte Fachkräfte werden von den Unternehmen oft überregional rekrutiert, sodass gerade unter Akademikern eine hohe Mobilität zu beobachten ist. Aus der Perspektive der Bundesländer, die einen Großteil der Kosten der Akademikerausbildung bestreiten, kann ein hoher Zu- bzw. Abwanderungssaldo eine Schieflage bei der finanziellen Lastenverteilung zur Folge haben. Es liegt auf der Hand, dass einzelne Bundesländer im Ausbildungswesen nur ungern eine Zubringerfunktion für andere übernehmen wollen.

Exchange Rates and FDI: Goods versus Capital Market Frictions
Claudia M. Buch, J. Kleinert
World Economy,
forthcoming
Abstract
Changes in exchange rates affect countries through their impact on cross-border activities such as trade and foreign direct investment (FDI). With increasing activities of multinational firms, the FDI channel is likely to gain in importance. Economic theory provides two main explanations why changes in exchange rates can affect FDI. According to the first explanation, FDI reacts to exchange rate changes if there are information frictions on capital markets and if investment depends on firms’ net worth (capital market friction hypothesis). According to the second explanation, FDI reacts to exchange rate changes if output and factor markets are segmented, and if firm-specific assets are important (goods market friction hypothesis). We provide a unified theoretical framework of these two explanations. We analyse the implications of the model empirically using a dataset based on detailed German firm-level data. We find greater support for the goods market than for the capital market friction hypothesis.

Monetary Policy and Financial (In)stability: An Integrated Micro–Macro Approach
Ferre De Graeve, Thomas Kick, Michael Koetter
Journal of Financial Stability,
No. 3,
2008
Abstract
Evidence on central banks’ twin objective, monetary and financial stability, is scarce. We suggest an integrated micro–macro approach with two core virtues. First, we measure financial stability directly at the bank level as the probability of distress. Second, we integrate a microeconomic hazard model for bank distress and a standard macroeconomic model. The advantage of this approach is to incorporate micro information, to allow for non-linearities and to permit general feedback effects between financial distress and the real economy. We base the analysis on German bank and macro data between 1995 and 2004. Our results confirm the existence of a trade-off between monetary and financial stability. An unexpected tightening of monetary policy increases the probability of distress. This effect disappears when neglecting microeffects and non-linearities, underlining their importance. Distress responses are largest for small cooperative banks, weak distress events, and at times when capitalization is low. An important policy implication is that the separation of financial supervision and monetary policy requires close collaboration among members in the European System of Central Banks and national bank supervisors.

Evaluating the German (New Keynesian) Phillips Curve
Rolf Scheufele
IWH Discussion Papers,
No. 10,
2008
Abstract
This paper evaluates the New Keynesian Phillips Curve (NKPC) and its hybrid
variant within a limited information framework for Germany. The main interest rests on the average frequency of price re-optimization of firms. We use the labor income share as the driving variable and consider a source of real rigidity by allowing for a fixed firm-specific capital stock. A GMM estimation strategy is employed as well as an identification robust method that is based upon the Anderson-Rubin statistic. We find out that the German Phillips Curve is purely forward looking. Moreover, our point estimates are consistent with the view that firms re-optimize prices every two to three quarters. While these estimates seem plausible from an economic point of view, the uncertainties around these estimates are very large and also consistent with perfect nominal price rigidity where firms never re-optimize prices. This analysis also offers some explanations why previous results for the German NKPC based on GMM differ considerably. First, standard GMM results are very sensitive to the way how orthogonality conditions are formulated. Additionally, model misspecifications may be left undetected by conventional J tests. Taken together, this analysis points out
the need for identification robust methods to get reliable estimates for the NKPC.

The Role of the Human Capital and Managerial Skills in Explaining the Productivity Gaps between East and West
Johannes Stephan, Wolfgang Steffen
Eastern European Economics,
No. 6,
2008
Abstract
Die Veröffentlichung beschäftigt sich mit den Determinanten von Produktivitätsgefällen zwischen Firmen in Europäischen Transitionsländern oder –regionen und Firmen in Westdeutschland. Die Analyse findet auf der Unternehmensebene statt und basiert auf einer einzigartigen Datenbank, welche durch Feldforschung erstellt worden ist. Die Determinanten werden in einer einfachen ökonometrischen Regression getestet und fokussieren auf Humankapital und modernes marktorientiertes Management. Die Ergebnisse sind insofern neu als sie eine Lösung anbieten, wie die widersprüchlichen Ergebnisse anderer Analysen zu formalen Qualifikationsmustern in Ost- und Westdeutschland zu erklären sind. Darüber hinaus ist es aufgrund der Analyse möglich eine Art Humankapital und Expertise zu entwickeln, welche meist in post-sozialistischen Firmen gebraucht wird und sich auf bestimmte Ansprüche an eine konkurrenzfähige marktbasierte ökonomische Umwelt bezieht. Letztendlich findet die Analyse auch empirische Beweise für die Rolle einer verbesserten Kapitalausstattung für den Produktivitätsausgleich sowie für das Argument, dass die Unterschiede in Arbeitsproduktivität bedeutend in einer größeren arbeitsintensiveren Produktion verwurzelt sind, was jedoch nicht zu einem wettbewerblichen Nachteil führt.

Foreign Subsidiaries in the East German Innovation System – Evidence from Manufacturing Industries
Jutta Günther, Björn Jindra, Johannes Stephan
IWH Discussion Papers,
No. 4,
2008
Abstract
This paper analyses the extent of technological capability of foreign subsidiaries located in East Germany, and looks at the determinants of foreign subsidiaries’ technological sourcing behaviour. The theory of international production underlines the importance of strategic and regional level variables. However, existing empirical approaches omit by and large regional level factors. We employ survey evidence from the “FDI micro data- base” of the IWH, that was only recently made available, to conduct our analyses. We find that foreign subsidiaries are above average technologically active in comparison to the whole East German manufacturing. This can be partially explained by the industrial structure of foreign direct investment. However, only a limited share of foreign subsidiaries with R&D and/or innovation activity source technological knowledge from the East German innovation system. If a subsidiary follows a competence augmenting strategy or does local trade, it is more likely to source technological knowledge locally. The endowment of a region with human capital and a scientific infrastructure has a positive effect too. The findings suggest that foreign subsidiaries in East Germany are only partially linked with the regional innovation system. Policy implications are discussed.

Capital Stock Approximation using Firm Level Panel Data: A Modified Perpetual Inventory Approach
Steffen Müller
Jahrbücher für Nationalökonomie und Statistik,
No. 4,
2008
Abstract
Many recent studies exploring conditional factor demand or factor substitution issues use firm level panel data. A considerable number of establishment panels contains no direct information on the capital input, necessary for production or cost function estimation. Incorrect measurement of capital leads to biased estimates and casts doubt on any inference on output elasticities or input substitution properties. The perpetual inventory approach, commonly used for long panels, is a method that attenuates these problems. In this paper a modified perpetual inventory approach is proposed. This method provides more reliable measures for capital input when short firm panels are used and no direct information on capital input is available. The empirical results based on a replication study of Addison et al. (2006) support the conclusion that modified perpetual inventory is superior to previous attempts in particular when fixed effects estimation techniques are used. The method thus makes a considerable number of recently established firm panels accessible to more sophisticated production function or factor demand analyses.
