Abstract
In this paper, we investigate regional differences in the gender pay gap both theoretically and empirically. Within a spatial model of monopsonistic competition, we show that more densely populated labour markets are more competitive and constrain employers’ ability to discriminate against women. Utilizing a large administrative data set for western Germany and a flexible semi-parametric propensity score matching approach, we find that the unexplained gender pay gap for young workers is substantially lower in large metropolitan than in rural areas. This regional gap in the gap of roughly 10 percentage points remained surprisingly constant over the entire observation period of 30 years.

Cooperation Events, Ego-Network Characteristics and Firm Innovativeness – Empirical Evidence from the German Laser Industry
Muhamed Kudic, Katja Guhr
IWH Discussion Papers,
No. 6,
2013
Abstract
We study how firm innovativeness is related to individual cooperation events and the structure and dynamics of firms’ ego-networks employing a unique panel dataset for the full population of 233 German laser source manufactures between 1990 and 2010. Firm innovativeness is measured by yearly patent applications as well as patent grants with a two year time-lag. Network measures are calculated on the basis of 570 knowledge-related publicly funded R&D alliances. Estimation results from a panel data count model with fixed effects are suggestive of direct innovation effects due to individual cooperation events, but only as long as structural ego-network characteristics are neglected. Innovativeness is robustly related to ego-network size and ego-network brokerage whereas ego-network density reveals some surprising results.

Human Capital Mobility and Convergence – A Spatial Dynamic Panel Model of the German Regions
Alexander Kubis, Lutz Schneider
Abstract
Since the fall of the iron curtain in 1989, the migration deficit of the Eastern part of Germany has accumulated to 1.8 million people, which is over ten percent of its initial population. Depending on their human capital endowment, these migrants might either – in the case of low-skilled migration – accelerate or – in high-skilled case – impede convergence. Due to the availability of detailed data on regional human capital, migration and productivity growth, we are able to test how geographic mobility affects convergence via the human capital selectivity of migration. With regard to the endogeneity of the migration flows and human capital, we apply a dynamic panel data model within the framework of β-convergence and account for spatial dependence. The regressions indicate a positive, robust, but modest effect of a migration surplus on regional productivity growth. After controlling for human capital, the effect of migration decreases; this decrease indicates that skill selectivity is one way that migration impacts growth.

Determinants of Evolutionary Change Processes in Innovation Networks – Empirical Evidence from the German Laser Industry
Muhamed Kudic, Andreas Pyka, Jutta Günther
Abstract
We seek to understand the relationship between network change determinants, network change processes at the micro level and structural consequences at the overall network level. Our conceptual framework considers three groups of determinants – organizational, relational and contextual. Selected factors within these groups are assumed to cause network change processes at the micro level – tie formations and tie terminations – and to shape the structural network configuration at the overall network level. We apply a unique longitudinal event history dataset based on the full population of 233 German laser source manufacturers and 570 publicly-funded cooperation projects to answer the following research question: What kind of exogenous or endogenous determinants affect a firm’s propensity and timing to cooperate and enter the network? Estimation results from a non-parametric event history model indicate that young micro firms enter the network later than small-sized and large firms. An in-depth analysis of the size effects for medium-sized firms provides some unexpected yet quite interesting findings. The choice of cooperation type makes no significant difference for the firms’ timing to enter the network. Finally, the analysis of contextual determinants shows that cluster membership can, but do not necessarily, affect a firm’s timing to cooperate.

School Closures and Population Decline in Saxony-Anhalt
Walter Hyll, Lutz Schneider
Wirtschaft im Wandel,
No. 6,
2011
Abstract
Grundschulschließungen werden kritisiert und gefürchtet. Besonders in peripheren Regionen verbindet sich mit der Aufgabe einer Schule vielfach die Sorge des demographischen Unterganges der Gemeinde infolge einer Abwanderung junger Eltern und ausbleibender Zuwanderung junger Familien. Sind Grundschulschließungen aber tatsächlich Ursache einer Verschlechterung der Wanderungsbilanz? Im vorliegenden Beitrag wird diese Fragestellung für die Familienwanderung zwischen Gemeinden Sachsen- Anhalts im Zeitraum von 1991 bis 2008 beantwortet. Die Untersuchung vergleicht im ersten Schritt die Wanderungsraten von Gemeinden mit unterschiedlicher Grundschulausstattung. Im zweiten Schritt wird die Querschnittsbetrachtung um eine Längsschnittanalyse ergänzt: Hier interessiert die Frage, ob sich das Wanderungsverhalten ändert, wenn die letzte Schule einer Gemeinde geschlossen wird. Der Analyse zufolge übt die schulische Infrastruktur von Gemeinden in Sachsen-Anhalt einen signifikanten
Einfluss auf das Wanderungsverhalten der Familien mit jüngeren Kindern aus. So zeigt sich, dass nach der Schließung der letzten Grundschule die Zuzüge zurückgehen; überraschenderweise reduzieren sich jedoch auch die Fortzüge. Da sich beide Effekte gegenseitig gerade aufheben, ist eine Wirkung der Schließung per saldo jedoch nicht mehr erkennbar. Damit ist das Problem eines sich selbst verstärkenden Schrumpfungsprozesses zumindest mit Blick auf junge Familien empirisch nicht ersichtlich.
