Political Institutionalisation and Economic Specialisation in Polycentric Metropolitan Regions – The Case of the East German ‚Saxony Triangle‘
Peter Franz, Christoph Hornych
Urban Studies,
2010
Abstract
The rising focus of politicians as well as scientists in the EU on the large urban agglomerations as centres of economic growth is accompanied by political efforts to identify and to demarcate such agglomerations under the label ‘metropolitan regions’. This study develops a theoretical framework broaching the issue of cooperation between municipalities from the perspective of regional economics as well as political science. The framework is applied to the empirical case of the polycentric metropolitan region of the ‘Saxony triangle’ in east Germany. The results show that various intervening factors prevent intense co-operation between the actors in the region. Policy implications and conclusions for future research are discussed.

The Productivity Effect of Temporary Agency Work: Evidence from German Panel Data
Boris Hirsch, Steffen Müller
Economic Journal,
No. 562,
2012
Abstract
This study investigates the effect of temporary agency work on the user firm’s productivity. We hypothesise that using temporary agency work to enhance numerical flexibility and to screen job candidates may increase productivity, whereas temporary workers’ lower firm-specific human capital and spillover effects on the user’s permanent employees may adversely affect productivity. Other than the sparse existing literature on this issue, we exploit a large panel data set and control for time-invariant and time-varying unobserved heterogeneity by using the system GMM estimator. We find a robust hump-shaped effect of the extent of temporary agency work on the user firm’s productivity.

Competition, Risk-shifting, and Public Bail-out Policies
Reint E. Gropp, H. Hakenes, Isabel Schnabel
Review of Financial Studies,
No. 6,
2011
Abstract
This article empirically investigates the competitive effects of government bail-out policies. We construct a measure of bail-out perceptions by using rating information. From there, we construct the market shares of insured competitor banks for any given bank, and analyze the impact of this variable on banks' risk-taking behavior, using a large sample of banks from OECD countries. Our results suggest that government guarantees strongly increase the risk-taking of competitor banks. In contrast, there is no evidence that public guarantees increase the protected banks' risk-taking, except for banks that have outright public ownership. These results have important implications for the effects of the recent wave of bank bail-outs on banks' risk-taking behavior.

Determinants of the Efficiency of Regional Innovation Systems
Michael Fritsch, Viktor Slavtchev
Regional Studies,
No. 7,
2011
Abstract
Determinanten der technischen Effizienz von regionalen Innovationssystemen, Regional Studies. Wir analysieren Unterschiede in der Effizienz regionaler Innovationssysteme (RIS). Zunächst werden alternative Maße für die Effizienz von RIS diskutiert, die auf dem Konzept der Wissensproduktionsfunktion aufbauen. Die empirischen Ergebnisse deuten darauf hin, dass sowohl Spillover aus dem privaten Sektor als auch von Hochschulen und anderen öffentlichen Forschungseinrichtungen die Effizienz privater F&E-Aktivitäten positiv beeinflussen. Insbesondere die Intensität der Interaktion zwischen öffentlichen Einrichtungen und dem Privatsektor führt zu hoher Effizienz. Regionen, die durch Großbetriebe dominiert sind, weisen tendenziell eine geringere Effizienz der Innovationsaktivitäten auf als Regionen mit einer geringeren durchschnittlichen Betriebsgröße.

Non-union Worker Representation, Foreign Owners, and the Performance of Establishments
U. Jirjahn, Steffen Müller
Oxford Economic Papers,
No. 1,
2014
Abstract
Using German establishment data, this study provides the first econometric analysis on the interaction of establishment-level codetermination and foreign owners. Works councils are associated with higher productivity in domestic-owned establishments while they are associated with lower productivity in foreign-owned establishments. Our results conform to the notion that foreign ownership can involve strong tensions with the institutional patterns of the host country.

Labor Market Volatility, Skills, and Financial Globalization
Claudia M. Buch, C. Pierdzioch
Macroeconomic Dynamics,
No. 5,
2014
Abstract
We analyze the impact of financial globalization on volatilities of hours worked and wages of high-skilled and low-skilled workers. Using cross-country, industry-level data for the years 1970–2004, we establish stylized facts that document how volatilities of hours worked and wages of workers with different skill levels have changed over time. We then document that the volatility of hours worked by low-skilled workers has increased the most in response to the increase in financial globalization. We develop a dynamic stochastic general equilibrium model of a small open economy that is consistent with the empirical results. The model predicts that greater financial globalization increases the volatility of hours worked, and this effect is strongest for low-skilled workers.

Währung ohne Souverän: Zur Ursache und Überwindung der Euro-Krise
Hubert Gabrisch
Leviathan - Berliner Zeitschrift für Sozialwissenschaft,
No. 1,
2013
Abstract
Ich argumentiere, dass eine Währung einen Souverän braucht, um Stabilität auf den Finanzmärkten und in der Realwirtschaft zu sichern. Andernfalls würde eine Währungsunion über kurz oder lang zerfallen. Insofern ist die aktuelle Krise des Euro-Raums auf das Fehlen eines Souveräns zurückzuführen. Die Theorie des optimalen Währungsraums bringt keine Erkenntnisse zur Überwindung der Krise, weil sie die Separierung von Geld und Staat als Grundlage hat. Auch deshalb liefert sie eher eine Begründung für Reformen wie den Fiskalpakt, dem zufolge fiskalische Operationen von der Einschätzung der Finanzmärkte abhängen sollen. Ich zeige, wie der Fiskalpakt im Gegenteil zu einer tiefen Rezession und zu einer dauerhaften Kluft zwischen Gläubiger- und Schuldnerländern führen wird. Notwendig ist vielmehr eine Transformation der Währungsunion in einen souveränen Währungsraum, in dem eine effektive Koordination von Geld- und Fiskalpolitik zwischen einer EU-Finanzbehörde und der Zentralbank im Sinne einer funktionalen Fiskalpolitik möglich wird.

On the Economic Architecture of the Workplace: Repercussions of Social Comparisons among Heterogeneous Workers
Oded Stark, Walter Hyll
Journal of Labor Economics,
No. 2,
2011
Abstract
We analyze the impact on a firm’s profits and optimal wage rates, and on the distribution of workers’ earnings, when workers compare their earnings with those of co-workers. We consider a low-productivity worker who receives lower wage earnings than a high-productivity worker. When the low-productivity worker derives (dis)utility not only from his own effort but also from comparing his earnings with those of the high-productivity worker, his response to the sensing of relative deprivation is to increase the optimal level of effort. Consequently, the firm’s profits are higher, its wage rates remain unchanged, and the distribution of earnings is compressed.

Volatile Multinationals? Evidence from the Labor Demand of German Firms
Claudia M. Buch, A. Lipponer
Labour Economics,
No. 2,
2010
Abstract
Does more FDI make the world a riskier place for workers? We analyze whether an increase in multinational firms' activities is associated with an increase in firm-level employment volatility. We use a firm-level dataset for Germany which allows us to distinguish between purely domestic firms, exporters, domestic multinationals and foreign multinationals. Employment in multinationals could be more volatile than employment in domestic firms if multinationals were facing more volatile demand or if they react more to aggregate developments. We therefore decompose the labor demand of firms into their reaction and their exposure to aggregate developments. We find no above-average wage and output elasticities for multinational firms.
