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.

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.

Determinants of Female Migration – The Case of German NUTS 3 Regions
Alexander Kubis, Lutz Schneider
IWH Discussion Papers,
No. 12,
2007
Abstract
Our study examines the regional patterns and determinants of migration flows of young women. At the NUTS-3 regional level, i.e. the district level (Kreise), the German internal migration flows of the year 2005 are explored. From descriptive statistics it can be seen that peripheral regions in East Germany face the strongest migration deficit with respect to young women, whereas agglomerations in West Germany but also in the East benefit from an intense migration surplus within this group. An econometric analysis of determinants of regional migration flows gives evidence of the importance of labour market, family-related and educational migration motives. Generally speaking, young women tend to choose regions with good income and job opportunities, in addition they seem to be attracted by regions enabling an appropriate balance between family and career. Furthermore the existence of excellent educational facilities is a significant influence for young women’s migration. This educationally motivated type of migration generates a long lasting effect on the regional migration balance, especially when the educational opportunities in the destination region are associated with adequate career perspectives for high qualified female graduates. In view of considerable losses due to migration, the study shows various options for action. An important course of action is to incorporate policy measures improving regional employment and income opportunities. Secondly, extending vocational and academic offers addressed to women seems to be a suitable way to stimulate women’s immigration. Moreover, enhancing the social infrastructure, which contributes to a satisfactory work life balance, might attract young women or at least reduce the number of them leaving a region.

Einkommenssicherung, Arbeitsmarktpolitik und Beschäftigung in Ostdeutschland
Herbert S. Buscher
Wirtschaft im Wandel,
No. 6,
2007
Abstract
Der Beitrag stellt drei in der Diskussion befindliche Ansätze vor, die zu einer Einkommenssicherung von entweder Arbeitslosen oder Beschäftigten im Niedriglohnbereich führen sollen. Namentlich handelt es sich um die Einführung eines flächendeckenden Mindestlohns, um das Kombilohnmodell des Sachverständigenrats sowie um den Workfare-Ansatz des IZA Bonn. Der Beitrag zeigt die wesentlichen „Bausteine“ der Modelle auf, die zu erwartenden Beschäftigungseffekte (einschließlich der fiskalischen Kosten, soweit möglich) und geht schließlich der Frage nach, wie eine Einführung der Modelle auf den ostdeutschen Arbeitsmarkt wirken könnte.

Der Einfluß von Führungsfunktionen auf das Regionaleinkommen: eine ökonometrische Analyse deutscher Regionen
Ulrich Blum
Wirtschaft im Wandel,
No. 6,
2007
Abstract
Das in den späten 70er Jahren entwickelte Potentialfaktorkonzept, das die Beziehung zwischen regional weitgehend immobilen Produktionsfaktorkapazitäten und dem regionalen Entwicklungspotential analysiert, wird auf die Regionen des vereinten Deutschlands angewendet. Ziel ist es, auf der Grundlage von Daten des Jahres 2003 die Beziehung auszuweisen und innerdeutsch in Bezug auf die wirtschaftliche Leistungsfähigkeit differenzierende Faktoren zu identifizieren. Daher werden neben der Erklärung von Arbeit sowie öffentlichem und privatem Kapital auch die Kapazität der Führungsfunktionen und die privaten Ausgaben für Forschung und Entwicklung einbezogen. Zunächst zeigt sich, daß drei Faktoren für die Einkommenslücke des Ostens von rund 40% besonders verantwortlich zeichnen: Die weitgehend fehlenden Führungsfunktionen, die niedrigen FuE-Ausgaben und die Erreichbarkeit im überörtlichen Verkehrssystem. Rund 85% des ostdeutschen Rückstands werden durch sie erklärt. Natürlich ist bekannt, daß eine Interdependenz zwischen Führungsfunktionen und wirtschaftlicher Leistungsfähigkeit besteht und damit eine einfache Kausalität nicht zwingend ist. Da aber durch den Einigungsprozeß Kombinatsstrukturen zerschlagen wurden und im Rahmen der Privatisierung der Aufbau von örtlichen Führungsfunktionen kein vorgegebenes Ziel war, weshalb auch die Industrieforschung der DDR nur mit Anstrengungen – und dann nur partiell – in die Marktwirtschaft überführt werden konnte, steht hier diese Minderausstattung am Anfang der Ursachenforschung für die fehlende Ost-West-Konvergenz. Aus wirtschaftspolitischer Sicht muß damit die Forderung nach Unterstützung eines internen und externen Unternehmenswachstums Priorität gewinnen, um die Regionen wirtschaftlich zu ertüchtigen. Denn die Beziehung zwischen Produktivität, Unternehmensgröße und Internationalität der erstellten Güterstruktur ist aus theoretischer ebenso wie aus empirischer Sicht zwingend. In der Tat sind solche ostdeutschen Regionen besonders erfolgreich, denen dies vor allem durch den Aufbau leistungsfähiger Cluster gelungen ist.

Lower Firm-Specific Productivity Levels in East Germany and East European Industrial Branches: The Role of Managerial Factors
Johannes Stephan
Germany’s Economic Performance: From Unification to Euroization,
2007
Abstract
During the socialist era, companies in East Germany became much weaker than firms in West Germany in terms of technology and competitiveness. In large part, this may be rooted in the different incentive structures of the two systems: whereas in the West, the criterion for companies’ success was their ability to remain in business and generate income in a contestable market environment, firms in the East were required to fulfil a plan to which they were subjected without having their opinions considered.

Prekäre Einkommenslagen ind Deutschland - ein Ost-West-Vergleich 1996-2002
Herbert S. Buscher, Juliane Parys
Allgemeines Statistisches Archiv,
No. 4,
2006
Abstract
Der Beitrag untersucht die Verteilung der äquivalenzgewichteten Nettoeinkommen von Haushalten und Lebensgemeinschaft in West- und Ostdeutschland für die Zeit von 1996 bis 2002 auf der Grundlage der Daten des Mikrozensus. Die Untersuchung gliedert sich in einen deskriptiven Teil, der eindimensionale Maße zur Einkommensverteilung und zur Messung der Ungleichheit diskutiert, und in einen zweiten Teil, in dem auf der Basis eines Logit-Modells Determinanten bestimmt werden, die für prekäre Lebens- und Einkommenslagen ursächlich sein können. Ein besonderes Gewicht wird hierbei auf unterschiedliche Lebensformen und die Anzahl der Kinder gelegt. Die Ergebnisse zeigen ein deutlich höheres Armutsrisiko für Lebensgemeinschaften / Familien mit Kindern im Vergleich zu kinderlosen Paaren.

Where enterprises lead, people follow? Links between migration and FDI in Germany
Claudia M. Buch, J. Kleinert, Farid Toubal
European Economic Review,
No. 8,
2006
Abstract
Standard neoclassical models of economic integration are based on the assumptions that capital and labor are substitutes and that the geography of factor market integration does not matter. Yet, these two assumptions are violated if agglomeration forces among factors from specific source countries are at work. Agglomeration implies that factors behave as complements and that the country of origin matters. This paper analyzes agglomeration between capital and labor empirically. We use state-level German data to answer the question whether and how migration and foreign direct investment (FDI) are linked. Stocks of inward FDI and of immigrants have similar determinants, and the geography of factor market integration matters. There are higher stocks of inward FDI in German states hosting a large foreign population from the same country of origin. This agglomeration effect is confined to higher-income source countries.

Vertical Intra-industry Trade between EU and Accession Countries
Hubert Gabrisch
IWH Discussion Papers,
No. 12,
2006
Abstract
The paper analyses vertical intra-industry trade between EU and Accession countries, and concentrates on two country-specific determinants: Differences in personal income distribution and in technology. Both determinants have a strong link to national policies and to cross-border investment flows. In contrast to most other studies, income distribution is not seen as time-invariant variable, but as changing over time. What is new is also that differences in technology are tested in comparison with cost advantages from capital/labour ratios. The study applies panel estimation techniques with GLS. Results show country-pair fixed effects to be of high relevance for explaining vertical intraindustry trade. In addition, bilateral differences in personal income distribution and their changes are positive related to vertical intra-industry trade in this special regional integration framework; hence, distributional effects of policies matter. Also, technology differences turn out to be positively correlated with vertical intra-industry trade. However, the cost variable (here: relative GDP per capita) shows no clear picture, particularly not in combination with the technology variable.

Economic convergence across German regions in light of empirical findings
Udo Ludwig, John B. Hall
Cambridge Journal of Economics,
2006
Abstract
This paper challenges the convergence hypothesis advanced by R. Barro and X. Sala-i-Martin as it is applied to explain the forces behind, patterns exhibited by and time line for German regional convergence. Exposed in some detail are the spurious neoclassical and marginalist assumptions, purporting that 'automatic' forces would indeed bring about a convergence in per capita incomes between two German regions. A trend exhibiting slow growth in per capita income in Germany's eastern region renders a Beta coefficient so low as to rule out convergence altogether. In addition, capital fails to move between German regions in the pattern assumed by the convergence hypothesis.
