The Structure and Evolution of Inter-sectoral Technological Complementarity in R&D in Germany from 1990 to 2011

T. Broekel, Matthias Brachert
Journal of Evolutionary Economics, Nr. 4, 2015
Abstract
Technological complementarity is argued to be a crucial element for effective R&D collaboration. The real structure is, however, still largely unknown. Based on the argument that organizations’ knowledge resources must fit for enabling collective learning and innovation, we use the co-occurrence of firms in collaborative R&D projects in Germany to assess inter-sectoral technological complementarity between 129 sectors. The results are mapped as complementarity space for the Germany economy. The space and its dynamics from 1990 to 2011 are analyzed by means of social network analysis. The results illustrate sectors being complements both from a dyadic and portfolio/network perspective. This latter is important, as complementarities may only become fully effective when integrated in a complete set of different knowledge resources from multiple sectors. The dynamic perspective moreover reveals the shifting demand for knowledge resources among sectors at different time periods.

R&D Cooperation with Scientific Institutions: A Difference-in-difference Approach

Gunnar Pippel, V. Seefeld
Economics of Innovation and New Technology, Nr. 5, 2016
Abstract
Economists and business managers have long been interested in the impact of research and development (R&D) cooperation with scientific institutions on the innovation performance of firms. Recent research identifies a positive correlation between these two variables. This paper aims to contribute to the identification of the relationship between R&D cooperation with scientific institutions and the product and process innovation performance of firms by using a difference-in-difference approach. In doing so, we distinguish between two different types of scientific institutions: universities and governmental research institutes. For the econometric analyses, we use data from the German Community Innovation Survey. In total, data from up to 560 German service and manufacturing firms are available for the difference-in-difference analyses. The results suggest that R&D cooperation with universities and governmental research institutes has a positive effect on both product innovation and process innovation performance of firms.

Does Country Context Distance Determine Subsidiary Decision-making Autonomy? Theory and Evidence from European Transition Economies

Gjalt de Jong, Vo. van Dut, Björn Jindra, Philipp Marek
International Business Review, Nr. 5, 2015
Abstract
We studied an underrepresented area in the international business (IB) literature: the effect of country context distance on the distribution of decision-making autonomy across headquarters and foreign affiliates. Foreign affiliates directly contribute to the competitive advantages of multinational enterprises, highlighting the importance of such intra-firm collaboration. The division of decision-making autonomy is a core issue in the management of headquarters–subsidiary relationships. The main contribution of our paper is that we confront two valid theoretical frameworks – business network theory and agency theory – that offer contradictory hypotheses with respect to the division of decision-making autonomy. Our study is among the first to examine this dilemma with a unique dataset from five Central and Eastern European transition countries. The empirical results provide convincing support for our approach to the study of subsidiary decision-making autonomy.

On the Trail of Core–periphery Patterns in Innovation Networks: Measurements and New Empirical Findings from the German Laser Industry

Wilfried Ehrenfeld, Toralf Pusch, Muhamed Kudic
The Annals of Regional Science, Nr. 1, 2015
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?

Jutta Günther, Muhamed Kudic, Andreas Pyka
International Journal of Innovation Management, Nr. 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.

Works Councils and Labour Productivity: Looking beyond the Mean

Steffen Müller
British Journal of Industrial Relations, Nr. 2, 2015
Abstract
After more than 25 years of empirical investigation, the analysis of works council effects on establishment productivity is still an active field of economic research. I present first evidence for works council regression coefficients along the unconditional log labour productivity distribution in Germany. The highest (lowest) coefficients were found at the bottom (top) of the distribution, which suggests that works councils have the most beneficial effects at low levels of productivity. Importantly, coefficients are positive at each productivity level. The results shed light on a classical theoretical argument concerning moderating factors for the productivity effect of employee participation.

A Weighty Issue Revisited: The Dynamic Effect of Body Weight on Earnings and Satisfaction in Germany

Frieder Kropfhäußer, Marco Sunder
Applied Economics, Nr. 41, 2015
Abstract
We estimate the relationship between changes in the body mass index (bmi) and wages or satisfaction, respectively, in a panel of German employees. In contrast to previous findings, our dynamic models indicate an inverse u-shaped association between bmi and wages. As the implied maximum occurs in the ‘overweight’ category, the positive trend in weight may not yet constitute a major limitation to productivity. Further investigation points out a stronger association among young workers and workers with jobs that are less protected. Work satisfaction of young workers is associated with bmi beyond the effect of earnings.

Economic Failure and the Role of Plant Age and Size

Steffen Müller, Jens Stegmaier
Small Business Economics, Nr. 3, 2015
Abstract
This paper introduces a large-scale administrative panel data set on corporate bankruptcy in Germany that allows for an econometric analysis of involuntary exits where previous studies mixed voluntary and involuntary exits. Approximately 83 % of all bankruptcies occur in plants with not more than 10 employees, and 61 % of all bankrupt plants are not older than 5 years. The descriptive statistics and regression analysis indicate substantial negative age dependence with respect to bankruptcy risk but confirm negative size dependence for mature plants only. Our results corroborate hypotheses stressing increasing capabilities and positional advantage, both predicting negative age dependence with respect to bankruptcy risk due to productivity improvements. The results are not consistent with the theories explaining age dependence via imprinting or structural inertia.

Is There Monopsonistic Discrimination against Immigrants?

Boris Hirsch, Elke J. Jahn
Industrial and Labor Relations Review, Nr. 3, 2015
Abstract
The authors investigate immigrants’ and natives’ labor supply to the firm within an estimation approach based on a dynamic monopsony framework. Applying duration models that account for unobserved worker heterogeneity to a large administrative employer–employee data set for Germany, they find that immigrants supply labor less elastically to firms than do natives. Under monopsonistic wage setting, the estimated elasticity differential predicts a 7.7 log points wage penalty for immigrants thereby accounting for the entire unexplained native–immigrant wage differential of 5.8 to 8.2 log points. When further distinguishing immigrant groups differing in their time spent in the German labor market, their immigration cohort, and their age at entry, the authors find that the observed unexplained wage differential is larger for those groups that show a larger elasticity differential relative to natives. These findings not only suggest that search frictions are a likely cause of employers’ more pronounced monopsony power over their immigrant workers but also imply that employers profit from discriminating against immigrants.
