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.

Federal grants for local development to stop economic decline? – Lessons from Germany
Peter Haug, Martin T. W. Rosenfeld
Consequences of the International Crisis for European SMEs – Vulnerability and resilience. Routledge Studies in the European Economy, Routledge,
2012
Abstract
The chapter analyses theoretically and empirically the supply-side effects of the public investments funded by the German „Economic Stimulus Package II“(Konjunkturpaket II), which was implemented in 2009. In the theoretical part, we address the distortionary effects of investment grants on public capital provision and local economic development. According to the theoretical literature on the efficient provision of public goods, public inputs and economic growth, conditional investment grants have several negative allocation effects: First, they distort the relative factor prices for the local government stimulating excess public capital stocks and Pareto-inefficient provision of public goods. Second, long-term growth-enhancing effects of debt-financed public investment could only be expected for public inputs, which either directly increase the productivity of the private sector or increase factor productivity, especially by increasing the stock of human capital. In the empirical part, we find that despite of the recent increase in municipal investments in the German state of Saxony our regression results do not confirm a connection with the ESPII funds. Furthermore, no relationship between the municipal fiscal strength and the amount of ESPII grants received could be found. All in all, due to the focus of the grants on public consumption goods rather than public inputs only marginal future growth effects can be expected from the subsidized investments.

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.

What Drives Innovation Output from Subsidized R&D Cooperation? — Project-level Evidence from Germany
Michael Schwartz, Michael Fritsch, Jutta Günther, François Peglow
Technovation,
No. 6,
2012
Abstract
Using a large dataset of 406 subsidized R&D cooperation projects, we provide detailed insights into the relationship between project characteristics and innovation output. Patent applications and publications are used as measures for the innovation output of an R&D project. We find that large-firm involvement is strongly positively related with the number of patent applications, but not with the number of publications. Conversely, university involvement has positive effects on projects’ innovation output in terms of the number of publications but not in terms of patent applications. In general, projects’ funding as measure of projects’ size is an important predictor of the innovation output of R&D cooperation projects. No significant effects are found for the number of partners as (an alternative) measure of projects’ size, for spatial proximity between cooperation partners, for the involvement of a public institute for applied research, and for prior cooperation experiences. We derive conclusions for the design of R&D cooperation support schemes.

Abstract
The article is part of a booklet edited by the Centre for Science Saxony-Anhalt - the Expert Platform “Demographic Change”. The booklet provides an overview on 15 research projects funded by the ministry of education of Saxony Anhalt. The IWH project analyzes aspects of demographic change in peripheral regions by means of Saxony Anhalt. In particular, the IWH research focus is on how citizens in peripheral regions will behave if the provision with social services of public interest is reduced. The article provides findings on the impact of primary schools closures on demographic change.

The Impact of Government Procurement Composition on Private R&D Activities
Viktor Slavtchev, Simon Wiederhold
Abstract
This paper addresses the question of whether government procurement can work as a de facto innovation policy tool. We develop an endogenous growth model with quality-improving in-novation that incorporates industries with heterogeneous innovation sizes. Government demand in high-tech industries increases the market size in these industries and, with it, the incentives for private firms to invest in R&D. At the economy-wide level, the additional R&D induced in high-tech industries outweighs the R&D foregone in all remaining industries. The implications of the model are empirically tested using a unique data set that includes federal procurement in U.S. states. We find evidence that a shift in the composition of government purchases toward high-tech industries indeed stimulates privately funded company R&D.

Effects of Local Public Investment into Infrastructure for Tourism: The Example of Saxony
Albrecht Kauffmann
Jahrbuch für Regionalwissenschaft,
No. 1,
2011
Abstract
The mass of investments into infrastructure for tourism in the so-called “New States” (Neue Länder) of the Federal Republic of Germany after 1990 was huge. They were aimed to the maintenance and recovery, respectively of competitiveness of traditional destinations, as well as to promote service-oriented structural change in industrial wastelands. A big part of these investments was supported by funds of the so called “Joint Task for Improving the Regional Economic Structure”. We analyse the effects of local public investment into infrastructure for tourism supported by investment grants on the local employment in accommodation and food service activities in the state of Saxony. The results provide evidence for correlations between special types of investment in the time period 2000–2007 and the development of employment in hospitality industry. However, this is subject to some requirements, such as the existence of complementary factors, or an existing regional touristic tradition as well.

Cooperation propensity and public cooperation funding in the German Laser Industry
Muhamed Kudic, Katja Guhr, I. Bullmer, Jutta Günther
Wirtschaft im Wandel,
No. 3,
2011
Abstract
The high-tech strategy of the federal government defines eight key technologies, including laser industry as a part of the optical technologies. This study provides a first descriptive overview of cooperation propensity and public cooperation funding for German Laser Source manufacturers between 1990 and 2010. Results show that the industry in general was characterized by expansion even though there were periods with a high degree of fluctuations. The spatial analysis of firm entries and exits reveals some interesting insights. The majority of large laser source companies are located in Bavaria, Baden-Württemberg and Thuringia. These regional distribution patterns hold for the absolute number of publicly funded cooperation projects. When considering the relative number of collaborative projects per firm and region the picture changes. It turns out that especially laser source manufacturers in Thuringia, Rhineland-Palatinate and Hamburg show up the highest cooperation propensities and an above-average demand for public funding.

Analyzing Innovation Drivers in the German Laser Industry: the Role of Positioning in the Social and Geographical Space
Muhamed Kudic, Peter Bönisch, Iciar Dominguez Lacasa
Abstract
Empirical and theoretical contributions provide strong evidence that firm-level performance outcomes in terms of innovativeness can either be determined by the firm’s position in the social space (network effects) or by the firm’s position in the geographical space (co-location effects). Even though we can observe quite recently first attempts in bringing together these traditionally distinct research streams (Whittington et al. 2009), research on interdependent network and geographical co-location effects is still rare. Consequently, we seek to answer the following research question: considering that the effects of social and geographic proximity on firm’s innovativeness can be interdependent, what are the distinct and combined effects of firm’s network and geographic position on firm-level innovation output? We analyze the innovative performance of German laser source manufacturers between 1995 and 2007. We use an official database on publicly funded R&D collaboration projects in order to construct yearly networks and analyze firm’s network positions. Based on information on population entries and exits we calculate various types of geographical proximity measures between private sector and public research organizations (PRO). We use patent grants as dependent variable in order to measure firm-level innovation output. Empirical results provide evidence for distinct effect of network degree centrality. Distinct effect of firm’s geographical co-location to laser-related public research organization promotes patenting activity. Results on combined network and co-location effects confirms partially the existence of in-terdependent proximity effects, even though a closer look at these effects reveals some ambiguous but quite interesting findings.

Energy Efficiency of the Housing Stock: Are potential savings overrated?
Claus Michelsen, S. Müller-Michelsen
Wirtschaft im Wandel,
No. 9,
2010
Abstract
A core element of the European Climate Protection Policy is the reduction of Energy usage in private households. Legal instruments focus particularly on private multifamily housing. When refurbishing or building a new home, the German regulation for energy saving in buildings and building systems, Energieeinsparverordnung (EnEV 2009), thereby formulates relatively strict standards on energy conservation. But these standards mainly address the technical potentials of energy efficiency gains instead of considering market conditions and different types of housing, especially their age. Theory suggests that legal settings therefore retain owners to refurbish their homes, when returns on investment are negative, especially in regions where market conditions do not allow for higher rents or the costs of refurbishment are too high.
The article presents evidence for these theoretical considerations: based on a large scale sample provided by the company ista Germany, it can be shown, that energy usage differs by the age of dwellings and by the standard of refurbishment. Data suggests that the assumed potentials of energy conservation, which are mainly motivated by technical considerations, are too high. The differences may be a result of different cost functions of refurbishment. Further evidence for this finding is provided by architectural considerations.
As a result, the article suggests to legally distinguishing between different types of housing and to consider market conditions, when providing public funding for energy efficiency. It is suggested to implement a two multidimensional strategy, considering climate protection, urban development issues and the rationality of real estate investors.
