Teacher Experience and the Class Size Effect - Experimental Evidence
Steffen Müller
Journal of Public Economics,
2013
Abstract
We analyze teacher experience as a moderating factor for the effect of class size reduction on student achievement in the early grades using data from the Tennessee STAR experiment with random assignment of teachers and students to classes of different sizes. The analysis is motivated by the high costs of class size reductions and the need to identify the circumstances under which this investment is most rewarding. We find a class size effect only for senior teachers. The effect exists at all deciles of the achievement distribution but is less pronounced at lower deciles. We further show that senior teachers outperform rookies only in small classes. Interestingly, the class size effect is likely due to a higher quality of instruction in small classes.

Regions as Selection Environments? The Emergence of the Solar Industry in Germany from 1992 to 2008
Matthias Brachert, Christoph Hornych, Peter Franz
European Planning Studies,
No. 11,
2013
Abstract
The spatial evolution of the German solar industry is analysed in the light of the “window of locational opportunity” and the “selection environment” approach. The paper argues that differences in the regions' ability to promote the emergence of local external economies contribute to increasing regional differentiation in the German structure of the industry. Applied empirical methods enclose longitudinal firm entry and network analysis. A special focus is given upon the realignment processes in the science system. Our findings show a relatively rapid spatial concentration of production in eastern Germany since the year 2000. This process is accompanied by intensified networking between firms and between firms and universities as well as research institutes. The responsiveness of regional institutions and the self-organizing capabilities of the solar firms substantiate some propositions of the “selection environment” approach.

FDI Micro Database – Methodological Note – Survey 2012 in East Germany
Jutta Günther, Andrea Gauselmann, Björn Jindra, Philipp Marek, Jan Engelhardt
Einzelveröffentlichungen,
2012
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.

The Effects of Building Energy Codes in Rental Housing: The German Experience
Claus Michelsen, Sebastian Rosenschon
Economics Bulletin,
No. 4,
2012
Abstract
This paper investigates the effect of building energy codes on housings' real energy consumption. We argue that building codes should have a twofold effect: lower levels of energy consumption after its implementation and decreasing energy requirements over time, because tighter building codes induce technical progress in the construction sector. We find evidence for both aspects. Based on a large and unique sample of energy certificates from Germany, this study is the first that deals with the empirical effects of energy efficiency standards in apartment/rental housing. Moreover, it is the first, which includes different stages of regulation.

Women Move Differently: Job Separations and Gender
Boris Hirsch, Claus Schnabel
Journal of Labor Research,
No. 4,
2012
Abstract
Using a large German linked employer–employee data set and methods of competing risks analysis, this paper investigates gender differences in job separation rates to employment and nonemployment. In line with descriptive evidence, we find lower job-to-job and higher job-to-nonemployment transition probabilities for women than men when controlling for individual and workplace characteristics and unobserved plant heterogeneity. These differences vanish once we allow these characteristics to affect separations differently by gender. When additionally controlling for wages, we find that both separation rates are considerably lower and also significantly less wage-elastic for women than for men, suggesting an interplay of gender differences in transition behaviour and the gender pay gap.

A Federal Long-run Projection Model for Germany
Oliver Holtemöller, Maike Irrek, Birgit Schultz
IWH Discussion Papers,
No. 11,
2012
Abstract
Many economic decisions implicitly or explicitly rely on a projection of the medium- or long-term economic development of a country or region. In this paper, we provide a federal long-run projection model for Germany and the German states. The model fea-tures a top-down approach and, as major contribution, uses error correction models to estimate the regional economic development dependent on the national projection. For the medium- and long-term projection of economic activity, we apply a production function approach. We provide a detailed robustness analysis by systematically varying assumptions of the model. Additionally, we explore the effects of different demographic trends on economic development.

Foreign Bank Entry, Credit Allocation and Lending Rates in Emerging Markets: Empirical Evidence from Poland
Hans Degryse, Olena Havrylchyk, Emilia Jurzyk, Sylwester Kozak
Journal of Banking and Finance,
No. 11,
2012
Abstract
Earlier studies have documented that foreign banks charge lower lending rates and interest spreads than domestic banks. We hypothesize that this may stem from the superior efficiency of foreign entrants that they decide to pass onto borrowers (“performance hypothesis”), but could also reflect a different loan allocation with respect to borrower transparency, loan maturity and currency (“portfolio composition hypothesis”). We are able to differentiate between the above hypotheses thanks to a novel dataset containing detailed bank-specific information for the Polish banking industry. Our findings demonstrate that banks differ significantly in terms of portfolio composition and we attest to the “portfolio composition hypothesis” by showing that, having controlled for portfolio composition, there are no differences in lending rates between banks.

The Synchronization of Wage Dynamics across EMU Members: A Test of the Endogeneity Hypothesis
Herbert S. Buscher, Hubert Gabrisch
Empirica,
No. 3,
2012
Abstract
We test the hypothesis of an endogenous currency area for the labor market of the Euro area: has the introduction of a common currency caused wage dynamics to become more synchronized and to be able to cushion for asymmetric shocks? Trade intensity, sector specialization and financial integration are tested for being the driving forces for the endogenous synchronization of wage dynamics. We use regression techniques with instrument variables, and find evidence of persistent asymmetries in nominal wage formation, despite a single currency and monetary policy. We explain the result with more specialization following financial integration, and with still existing differences in wage formation and labor market institutions. We conclude that the euro zone is not endogenous with respect to wage formation. Rather, there are incentives for beggar-thy-neighbor policies in the Euro area.

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.
