The Relationship between Knowledge Intensity and Market Concentration in European Industries: An inverted U-Shape
Niels Krap, Johannes Stephan
IWH Discussion Papers,
No. 3,

Abstract
This paper is motivated by the European Union strategy to secure competitiveness for Europe in the globalising world by focussing on technological supremacy (the Lisbon - agenda). Parallel to that, the EU Commission is trying to take a more economic approach to competition policy in general and anti-trust policy in particular. Our analysis tries to establish the relationship between increasing knowledge intensity and the resulting market concentration: if the European Union economy is gradually shifting to a pattern of sectoral specialisation that features a bias on knowledge intensive sectors, then this may well have some influence on market concentration and competition policy would have to adjust not to counterfeit the Lisbon-agenda. Following a review of the available theoretical and empirical literature on the relationship between knowledge intensity and market structure, we use a larger Eurostat database to test the shape of this relationship. Assuming a causality that runs from knowledge to concentration, we show that the relationship between knowledge intensity and market structures is in fact different for knowledge intensive industries and we establish a non-linear, inverted U-curve shape.

The Transition to Post-industrial BMI Values Among US Children
John Komlos, Ariane Breitfelder, Marco Sunder
NBER Working Paper No. 13898,
No. 13898,
2008
Abstract
In our opinion, the trend in the BMI values of US children has not been estimated accurately. We use five models to estimate the BMI trends of non-Hispanic US-born black and white children and adolescents ages 2-19 born 1941-2006 on the basis of all NHES and NHANES data sets. We also use some historical BMI values for comparison. The increase in BMIZ values during the period considered was on average 1.3σ (95% CI: 1.16σ; 1.44σ) among black girls, 0.8σ for black boys, 0.7σ for white boys, and 0.6σ for white girls. This translates into an increase in BMI values of some 5.6, 3.3, 2.4, and 1.5 units respectively. While the increase in BMI values started among the birth cohorts of the 1940s among black females, the rate of increase tended to accelerate among all four groups born in the mid-1950s to early-1960s with the contemporaneous spread of TV viewing. The rate of increase levelled off somewhat thereafter. There is some indication that among black boys and white girls born after c. 1990 adiposity has remained unchanged or perhaps even declined. The affects of the IT revolution of the last two decades of the century is less evident. Some regional evidence leads to the speculation that the spread of automobiles and radios affected the BMI values of boys already in the interwar period. We infer that the incremental weight increases are associated with the labor-saving technological developments of the 20th century which brought about many faceted cultural and nutritional revolutions.

Vernetzung und einzelwirtschaftliche Effekte von Unternehmen der Kunststoff- und Biotechnologiebranche in Mitteldeutschland - eine Analyse am Beispiel der Clusterinitiativen „Chemie/Kunststoffe“ und „Biotechnologie/Life Sciences“
Walter Komar
IWH-Sonderhefte,
No. 2,

Abstract
According to theoretical implications the success of enterprises benefits from co-operation in clusters and networks. Studies of cluster and network processes show this for the industries chemistry/plastics and biotechnology/Life Sciences in Central Ger-many. Therefore enterprises which are organized in networks have better economic characteristics. Estimations of the productivity of firms using co-operation-based and non-co-operation-based factors as independent variables reveal a significantly positive influence of the propensity to co-operate as well as networking. In this regard scientific institutions and universities located in the region of firms play an important role. From this analysis it can be generalized and concluded, also concerning other industries, that networks emerge automatically under certain conditions. Nevertheless their creation and development should be encouraged, e.g. by efficiency strengthening of public research and university education as well as the intensification of co-operation and networking between the scientific and the corporate sector. This can promote the technology and human capital transfer.

Abstract
According to theoretical implications the succes of enterprises benefits from co-operation and integration into networks. Enterprises of the biotechnology sector in particular have a high propensity to build up co-operations. Estimations of the growth of firms using co-operation-based and non-co-operation-based factors as independent variables reveal a significantly positive influence of the propensity of co-operation as well as networking. In this regard scientific institutions and universities located in geographical proximity of firms play an important role. From this analysis it can be generalized and concluded, concerning other industries too, that networks emerge automatically under certain conditions. Nevertheless their creation and development should be encouraged, e.g. by efficiency incentives for public research and education of universities as well as an intensification of co-operation and networking between the scientific and the corporate sector. This can promote the technology and human capital transfer.

Price Competition between an Expert and a Non-Expert
Jan Bouckaert, Hans Degryse
International Journal of Industrial Organization,
No. 6,
2000
Abstract
This paper characterizes price competition between an expert and a non-expert. In contrast with the expert, the non-expert's repair technology is not always successful. Consumers visit the expert after experiencing an unsuccessful match at the non-expert. This re-entry affects the behavior of both sellers. For low enough probability of successful repair at the non-expert, all consumers first visit the non-expert, and a 'timid-pricing' equilibrium results. If the non-expert's repair technology performs well enough, it pays for some consumers to disregard the non-expert a visit. They directly go to the expert's shop, and an 'aggressive-pricing' equilibrium pops up. For intermediate values of the non-expert's successful repair a 'mixed-pricing' equilibrium emerges where the expert randomizes over the monopoly price and some lower price.

Innovative Milieux: Advanced Posts of Interpenetration between the Economic System and the Science System
Peter Franz
IWH Discussion Papers,
No. 71,
1998
Abstract
A growing number of governments, political parties, and enterprises set the theme „innovation“ on their agenda and join in the global race to more competitive national economies. In this race the concept of the „innovative milieu“ serves as an important point of orientation and as a political target that, on the first glance, seems to be transferable in concrete political measures. A basic feature of innovative milieux is the quick and easy transfer of knowledge to products in demand. This speed-up in the diffusion of knowledge is not only interesting with respect to the economic advantages but also with respect to science. It is the basic thesis of this paper that innovative milieux represent special cases where the economic system and the science system interpenetrate in an extreme way. Empirical findings show that the actors of innovative milieux have a strong cultural proximity to basic attitudes and behavior within the science system. This relates to the institutionalization of trial and error, the reinforcement of exploratory behavior, the flow of information, and to a special mixture of cooperation and competition. An essential feature of innovative milieux derives from the network relations of its actors. These relations have to be balanced a) to the need to create trust and reduce uncertainty, and b) to the need to stay permeable enough for linkages with new actors from outside. With regard to time innovative milieux have to be conceived from an evolutionary perspective. This involves several steps: Development of prerequisites, consolidation, attraction of labor and enterprises from other regions. From the evolutionary perspective, too, possible factors of preventing or accelerating the „entropic death“ (Camagni 1991) of innovative milieux can be discussed. The exceptional character of innovative milieux has consequences for innovation-oriented political strategies. The self-enforcing dynamics of innovative milieux create a tendency to more economic inequality between regions (core-periphery differences). This is contradictory to political strategies in which innovation-oriented policy is applied to reach an offset between prospering and impoverished regions. In many cases a strategy starting from the assumption of an enduring non-innovative milieu seems to be more realistic and more promising. Further on, the new more direct links between enterprises and research institutes question the current shape of technology transfer institutions. Finally the potential effects of the new trend to encourage the entrepreneurship of research staff on the science system are discussed.
