Unobservable industry characteristics and the innovation-concentration-advertising-maze: Evidence from an econometric study using panel data for manufacturing industries in the FRG, 1979–1986

In discussing the nexus between innovations and market structure it is often argued that industry characteristics (called opportunities) might play an important role as determinants of innovation, and that simultaneity rather than one-way causality prevails. We consider a three-equation model for innovation, advertising, and concentration. Based on pooled cross-section time-series data for 26 German manufacturing industries we estimate single equation models with and without fixed industry and/or time effects (to control for unobservable industry or time effects, respectively) and simultaneous equation systems including fixed effects, and controlling for extreme cases (outliers) or not. Furthermore, we use two different measures for innovations, i.e., the percentage of shipments due to new products, and the percentage of firms which classified themselves as innovators. Our results can be summarized as follows: (1) The firm size has no significant effect on innovation. One can, therefore, not conclude from this data set that large firms are more innovative than small ones; (2) unobservable industry effects do matter; (3) the treatment of outliers does matter; (4) simultaneity does matter (5) the way innovations are measured does matter; (6) different stories could be told based on the results of the systems of interdependent equations estimated.Earlier versions of this paper were presented at the annual meeting of the committee of industrial economists of the Verein fuer Socialpolitik at Hohenheim University in March, 1990, and at the 1990 conferences of the European Economic Association and the European Association for Research in Industrial Economics in Lisboa. We would like to thank participants of these meetings and three anonymous referees for helpful comments. A more complete version of the paper with a set of tables for the results of all computations is available from the authors on request.     

Graduate nurse perceptions of the work experience

Findings from a longitudinal study on the perceptions of the work environment and job satisfaction for new graduate nurses in the first 18 months of employment at a Magnet Midwestern urban academic pediatric medical center are described. The findings indicated that orientation assisted the new graduate to become confident in his/her clinical competence and work management. By 18 months, the new graduate felt satisfied with access to resources and the ability to participate in professional development opportunities. The results suggest that the new graduate nurse's career adjustment extends beyond mastering clinical skills and includes a lifestyle adjustment to a profession that requires service 24 hours a day, 7 days a week.     

Management von Terrorrisiken in Deutschland — eine empirische Analyse

In this article insurance is considered as a means for allocating terrorism risk. After September 11^th, 2001 several countries, among them Germany, Great Britain, and the United States, have intervened on the markets for terrorism insurance. In Germany a primary insurance company was founded by the government and private insurers to supply cover for this peril. Using a full dataset of the demand for terrorism insurance this paper provides an evaluation of the intervention on the market for terrorism insurance in Germany. The results derived are then used to suggest ways to improve the allocation of terrorism risk in Germany.
