Abstract
It has been frequently argued that a firm’s location in the core of an industry’s innovation network improves its ability to access information and absorb technological knowledge. The literature has still widely neglected the role of peripheral network positions for innovation processes. In addition to this, little is known about the determinants affecting a peripheral actors’ ability to reach the core. To shed some light on these issues, we have employed a unique longitudinal dataset encompassing the entire population of German laser source manufacturers (LSMs) and laser-related public research organizations (PROs) over a period of more than two decades. The aim of our paper is threefold. First, we analyze the emergence of core–periphery (CP) patterns in the German laser industry. Then, we explore the paths on which LSMs and PROs move from isolated positions toward the core. Finally, we employ non-parametric event history techniques to analyze the extent to which organizational and geographical determinates affect the propensity and timing of network core entries. Our results indicate the emergence and solidification of CP patterns at the overall network level. We also found that the paths on which organizations traverse through the network are characterized by high levels of heterogeneity and volatility. The transition from peripheral to core positions is impacted by organizational characteristics, while an organization’s geographical location does not play a significant role.

Taking the First Step - What Determines German Laser Source Manufacturers' Entry into Innovation Networks?

International Journal of Innovation Management,
No. 5,
2015
Abstract
Early access to technological knowledge embodied in the industry’s innovation network can provide an important competitive advantage to firms. While the literature provides much evidence on the positive effects of innovation networks on firms’ performance, not much is known about the determinants of firms’ initial entry into such networks. We analyze firms’ timing and propensity to enter the industry’s innovation network. More precisely, we seek to shed some light on the factors affecting the duration between firm founding and its first cooperation event. In doing so, we apply a unique longitudinal event history dataset based on the full population of German laser source manufacturers. Innovation network data stem from official databases providing detailed information on the organizations involved, subject of joint research and development (R&D) efforts as well as start and end times for all publically funded R&D projects between 1990 and 2010. Estimation results from a non-parametric event history model indicate that micro firms enter the network later than small-sized or large firms. An in-depth analysis of the size effects for medium-sized firms provides some unexpected findings. The choice of cooperation type makes no significant difference for the firms’ timing to enter the network. Finally, the analysis of geographical determinants shows that cluster membership can, but do not necessarily, affect a firm’s timing to cooperate.

The Age of Global Value Chains: Maps and Policy Issues
Joao Amador, Filippo di Mauro
CEPR Press,
2015
Abstract
Global value chains (GVCs) - referring to the cross-border flows of goods, investment, services, know-how and people associated with international production networks - have transformed the world. Their emergence has resulted in a complete reconfiguration of world trade, bearing a strong impact on the assessment of competitiveness and economic policy. The contributions to this eBook are based on research carried out within the scope of the Eurosystem Competitiveness Research Network (CompNet), bringing together participants from EU national central banks, universities and international organisations interested in competitiveness issues. The mapping of GVCs and full awareness about their implications are essential to informed public debate and improved economic policy.

Isolation and Innovation – Two Contradictory Concepts? Explorative Findings from the German Laser Industry
Wilfried Ehrenfeld, T. Pusch, Muhamed Kudic
IWH Discussion Papers,
No. 1,
2015
Abstract
We apply a network perspective and study the emergence of core-periphery (CP) structures in innovation networks to shed some light on the relationship between isolation and innovation. It has been frequently argued that a firm’s location in a densely interconnected network area improves its ability to access information and absorb technological knowledge. This, in turn, enables a firm to generate new products and services at a higher rate compared to less integrated competitors. However, the importance of peripheral positions for innovation processes is still a widely neglected issue in literature. Isolation may provide unique conditions that induce innovations which otherwise may never have been invented. Such innovations have the potential to lay the ground for a firm’s pathway towards the network core, where the industry’s established technological knowledge is assumed to be located.
The aim of our paper is twofold. Firstly, we propose a new CP indicator and apply it to analyze the emergence of CP patterns in the German laser industry. We employ publicly funded Research and Development (R&D) cooperation project data over a period of more than two decades. Secondly, we explore the paths on which firms move from isolated positions towards the core (and vice versa). Our exploratory results open up a number of new research questions at the intersection between geography, economics and network research.

Spatial Development in View of the Re-structuring of Public Administrations – What are the Implications of the Individual Contributions?
Martin T. W. Rosenfeld, M. Gather
Gebiets- und Verwaltungsstrukturen im Umbruch: Beiträge zur Reformdiskussion aus Erfahrungen in Sachsen, Sachsen-Anhalt und Thüringen,
No. 360,
2015
Abstract
It must be clear that any kind of appraisal drawn from the results of the individual papers can only be an interim one. Many of the issues raised in the pertinent field of investigation could only be touched upon without being sufficiently debated. In other cases the results of the papers show that further and more thorough investigations are urgently required. It may be stated that public administration structures are basically in a state of constant change, and must repeatedly be adapted to changing economic and social framework conditions. In terms of legal boundaries to territorial restructuring, it should be noted that the size of a municipality may not be permitted to obstruct either the political participation of citizens or the possibility of the municipal decision-makers being sufficiently well-informed.
The overall picture furthermore suggests that reforms in the public sector sphere that are initiated by state actors (i.e. top down) are always extremely complicated affairs.
The objective of the regional working group of the Academy of Spatial Research and Planning (ARL) for the states Sachsen, Sachsen-Anhalt and Thüringen was to highlight some of the most significant aspects of the process of municipal re-structuring and its effects on spatial development, considering these in the three states against the background of current discussions and reform measures.

Coordination between Municipalities and Local Non-Municipal Public Units (NMPUs) for Supporting Urban Economic Development: Theoretical Analysis and Empirical Evidence for the Example of Universities in Germany
Martin T. W. Rosenfeld, J. Hinz
Koordination raumwirksamer Politik: Mehr Effizienz und Wirksamkeit von Politik durch abgestimmte Arbeitsteilung,
2015
Abstract
In many European cities, policymakers are trying to change the local paths of economic development to head in new directions, e.g. by trying to become a location for Non-Municipal Public Units (NMPUs), like federal special agencies, state museums, military bases, universities or publicly funded research institutes. But as the competencies for such local NMPUs are allocated to higher levels of government, the municipal level has no direct formal institutional responsibilities for influencing their location. Once a NMPU has chosen a certain location, support from the municipality may, however, stabilize the NMPU. There are some categories of NMPUs that should have considerable interest in local conditions, as determined by the municipal level. This paper first theoretically categorizes NMPUs with regard to their importance for the urban economy, with regard to the importance of local conditions for the performance of NMPUs and with regard to their degree of fiscal autonomy. It is shown that universities are one example of NMPUs where the relevance of coordinating activities with the municipalities is fairly high. The benefits of universities for local economic development have often been discussed. From the point of view of universities, their capacity to attract human capital depends on factors which may be influenced by the municipalities. This means that there is a reciprocal relationship between municipalities and universities; coordination by cooperation between the partners could be useful for both – but in practice there is often a lack of cooperation. Information policy is one relevant field for coordination: the city should highlight publicly the advantages of local universities; the universities should highlight the advantages of their city. As information policy is a field for which empirical data is available, the empirical part of the paper presents results from an analysis based on the internet presentations of selected cities and universities. It is shown that in most cities the level of coordination in this field is so far quite low. One possible way to achieve a higher degree of coordination could be to introduce fiscal incentives for cities.

Bottom-up or Direct? Forecasting German GDP in a Data-rich Environment
Katja Drechsel, Rolf Scheufele
Abstract
This paper presents a method to conduct early estimates of GDP growth in Germany. We employ MIDAS regressions to circumvent the mixed frequency problem and use pooling techniques to summarize efficiently the information content of the various indicators. More specifically, we investigate whether it is better to disaggregate GDP (either via total value added of each sector or by the expenditure side) or whether a direct approach is more appropriate when it comes to forecasting GDP growth. Our approach combines a large set of monthly and quarterly coincident and leading indicators and takes into account the respective publication delay. In a simulated out-of-sample experiment we evaluate the different modelling strategies conditional on the given state of information and depending on the model averaging technique. The proposed approach is computationally simple and can be easily implemented as a nowcasting tool. Finally, this method also allows retracing the driving forces of the forecast and hence enables the interpretability of the forecast outcome.

Stale Information, Shocks, and Volatility
Reint E. Gropp, A. Kadareja
Journal of Money, Credit and Banking,
No. 6,
2012
Abstract
We propose a new approach to measuring the effect of unobservable private information on volatility. Using intraday data, we estimate the effect of a well-identified shock on the volatility of stock returns of European banks as a function of the quality of public information available about the banks. We hypothesize that as publicly available information becomes stale, volatility effects and its persistence increase, as private information of investors becomes more important. We find strong support for this idea in the data. We further show that stock volatility is higher just before important announcements if information is stale.

Cluster Policies in the Federal States of Bavaria and Thuringia: Discrepancies between Practice and Theory
Gerhard Heimpold
Wirtschaft im Wandel,
No. 10,
2011
Abstract
The contribution analyzes cluster policies pursued in the Federal States of Bavaria and Thuringia. The investigation is based on the exploration of government documents. In both countries cluster policy is target at strengthening competitiveness. The documents explored do not reveal an economic justification for cluster policy in the sense of eliminating market failures, e. g. externalities, information asymmetries and coordination failures. Therefore, it is unclear whether the support schemes under consideration really tie in with factors that hamper cluster evolution. Policies in both states support state-wider clusters and networks. The state-wide focus, however, might undervalue advantages of spatial proximity. As another critical point the ex-ante selection of industries or technologies eligible under cluster policy can be regarded. Despite readiness of considering new technologies etc., public administration generally suffers from a lack of information about the future development perspectives of industries and technologies. A way to mitigate the limited capability of public administration in terms of forecasting might be favoring economic support based on competition for the best concepts/projects instead of focusing on certain industries. Several support schemes offered by the Federal government in Germany are already competition-based. In Thuringia cluster policy is strongly motivated by several structural shortcomings, e. g. by the fragmented firm landscape mainly consisting of small units. Therefore, beyond cluster policy, the necessity will remain to abolish directly the structural shortcomings mentioned, especially by providing an economic environment that enhances firm growth.
