The Performance of Firms and Regions: Determinants and the Evaluation of Industrial Policy
This research group belongs to the IWH Research Cluster Productivity and Innovation. The group focuses on two main research questions: (i) What is the causal effect of cooperative innovation activities on the performance of firms and regions? (ii) What are the causal effects of public Research and Development (R&D) support schemes on the performance of firms and regions? The first research question concerns the dynamics of firms and regions as a result of their different innovation activities. We apply a micro-based integrative perspective on innovative activities which allows identifying causal effects of cooperative activities on specific outcomes (e. g., patent applications, scientific publications, employment growth, or productivity growth). Concerning the second research question, recent studies mainly focus on the evaluation of one specific subsidy scheme. Research in this group aims to overcome this shortcoming by considering various support schemes. Indicators for the firms’ success are (amongst others) patent applications and employment growth. The results allow insights for the future design of innovation support schemes.

A Professor Like Me: The Influence of Instructor Gender on College Achievement
in: The Journal of Human Resources , No. 2, 2009
Many wonder whether teacher gender plays an important role in higher education by influencing student achievement and subject interest. The data used in this paper help identify average effects from male and female college students assigned to male or female teachers. We find instructor gender plays only a minor role in determining college student achievement. Nevertheless, the small effects provide evidence that gender role models matter to some college students. A same-sex instructor increases average grade performance by at most 5 percent of its standard deviation and decreases the likelihood of dropping a class by 1.2 percentage points.
Soll die Höhe von Investitionszuschüssen an die Einführung von Umweltmanagementsystemen gekoppelt werden?
in: List Forum für Wirtschafts- und Finanzpolitik , No. 1, 2009
Economic policy has to reconcile a very complex set of objectives. Often, there is a trade-off between these policy targets. This paper focuses on objectives related to the improvement of the regional economic structure and the environmental protection. In Germany, regional policy is pursued among other things using investment grants within the Joint Task framework. At the federal state level, the Länder select and support sustainable investment projects. Some federal states have changed their investment support framework and aim for additional political targets such as environmental protection. Politicians in the Free State of Saxony discuss the option to offer an addition to the basic investment grant. This applies to plants that operate a certified environmental management system. Related to this current political debate this paper describes the effects of such regulatory measures. The article shows that under a particular set of circumstances the envisaged regulation actually could lower the overall level of supported investment and therefore would not stimulate the introduction of environmental management systems. Hence both political objectives would not be fully reconciled. The alternative way could be a direct support of environmental management systems as already introduced in selected other Länder.
Professor Qualities and Student Achievement
in: Review of Economics and Statistics , No. 1, 2009
This paper analyzes the importance of teacher quality at the college level. Instructors are matched to objective and subjective characteristics of teacher quality to estimate the impact of rank, salary, and perceived effectiveness on student performance and subject interest. Student and course fixed effects, time of day and week controls, and students' lack of knowledge about first-year instructors help minimize selection biases. Subjective teacher evaluations perform well in measuring instructor influences on students, while objective characteristics such as rank and salary do not. Overall, the importance of college instructor differences is small, but important outliers exist.
The Impact of R&D Collaboration Networks on the Performance of Firms and Regions: A Meta-analysis of the Evidence
in: IWH Discussion Papers , No. 14, 2012
Innovation is the result of an interactive process. Knowledge-intensive interactions among different partners are associated with a variety of advantages and disadvantages for the actors involved. Therefore, a rich body of literature investigating the impact of R&D collaboration networks on the innovation performance of firms and regions has developed over the last two decades. Those studies come to different results. The aims of this paper are manifold. First, the paper summarizes the results of the relevant literature. Second, a brief overview of the established methods and approaches used in the literature to investigate this research question is given. The third objective is to answer the question whether the achieved results in the literature are predetermined by the employed methods. Finally, relevant gaps for further research are identified. To answer these questions a meta-analysis of the relevant literature is conducted. This study shows that knowledge-intensive interactions have a rather positive impact on the performance of firms and regions. There is also evidence that the employed methods and approaches used in the literature to investigate this research question predetermine the outcome of the research.
Determinants of Evolutionary Change Processes in Innovation Networks – Empirical Evidence from the German Laser Industry
in: IWH Discussion Papers , No. 7, 2012
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.
Related Variety, Unrelated Variety and Regional Functions: Identifying Sources of Regional Employment Growth in Germany from 2003 to 2008
in: IWH Discussion Papers , No. 15, 2011
This article analyses how regional employment growth in Germany is affected by related variety, unrelated variety and the functions a region performs in the production process. Following the related variety literature, we argue that regions benefit from the existence of related activities that facilitate economic development. However, we argue that the sole reliance of related variety on standard industrial classifications remains debatable. Hence, we offer estimations for establishing that conceptual progress can indeed be made when a focus for analysis goes beyond solely considering industries. We develop an industry-function based approach of related and unrelated variety. Our findings suggest that related variety only in combination with a high functional specialization of the region facilitates regional growth in Germany. Additionally, also unrelated variety per se fails to wield influences affecting development of regions. It is rather unrelated, but functionally proximate variety in the groups “White Collar” and “Blue Collar Workers” positively affects regional employment growth.
“Geschäftsmodell Deutschland“ und außenwirtschaftliche Ungleichgewichte in der EU
in: CEGE - Center for European, Governance and Economic Development Research, Discussion Paper (110) , 2010
During the last decades, current account imbalances increased all over the world. In this context, countries with current account surpluses, in the European Union especially Germany, are increasingly blamed for their modest wage policies, which are seen as the main reason for global imbalances. On the basis of a panel data model, the present paper indentifies the determinants of current account imbalances of EU Member States. As the results show, price competitiveness is, although significant, only one out of many explanatory variables. Instead, current account imbalances are substantially caused by divergent propensities to save. This does not only relate to public, but also to private savings. Accordingly, demands addressed to Germany and other countries for higher wage agreements alone would be unrewarding. Instead, domestic demand in surplus countries should be increased by other means. On the other hand, in countries with current account deficits, existing savings potentials should be adequately exploited.
