Applications of Business Theatre in New Service Development

Applying business theatre can not only make a contribution in the context of change management, learning and development processes in companies, but also in the new service development (NSD) process. The authors show how business theatre can be applied in each step of NSD and present insights that they gained from a students’ and a research project. As service theatre addresses the “emotional side”, it is an ideal complement to a systematic NSD approach that addresses the “rational side” of a service.     

The internationalization of energy supply structures

The World Energy Conference will be held in Munich in mid-September. It will have to deal with diverse and complex problems of energy policy, for the seventies have presented tremendous challenges in the energy field. The control over oil—with 46% of the world supply still by far the most important source of energy—has been reorganized and two oil crises have exposed the flow of supplies to severe disruption and political hazards. As far as can be foreseen, the supply is unlikely to keep abreast of the world-wide rise of energy consumption. To replace the oil gradually will therefore be the major task in the energy field in the coming decades. What will be the supply position between now and the year 2000? And which structural changes will have to be effected?     

Over‐investment or risk mitigation? Corporate social responsibility in Asia‐Pacific,Europe, Japan,and the United States

We study the relationship of corporate social responsibility (CSR) and the distribution of stock returns for an international sample. Firms with a high level of CSR generally exhibit superior stock price synchronicity in the markets of Europe, Japan, and the United States. In particular, we identify optimal levels of CSR to minimize idiosyncratic risk for each region. Moreover, CSR has a mitigating effect on crash risk in Europe and the United States. In contrast, firms from the Asia‐Pacific region display CSR over‐investment followed by a higher crash risk. This appears to be a consequence of globalization, which forces firms from Asia‐Pacific to overinvest in CSR to adapt western standards.     

How to deal with dissent among experts. Risk evaluation of EMF in a scientific dialogue

This article describes the results of a scientific discourse which aimed at exploring the reasons for differences in expert health risk assessment of radio frequency electromagnetic fields of mobile telephony.

It starts with describing the structure of the discourse. Then, the reasons for the conflicting risk assessments are discussed. Differences are due to the selection and evaluation of relevant scientific studies by applying different scientific quality standards, to the methods used for generating a research synthesis and an overall risk evaluation. Consensus could be achieved regarding the selection of and the quality requirements for the scientific studies used for risk assessment as well as their significance for risk evaluation. However, dissent remained about the synthesis of scientific evidence into an overall risk evaluation and about the relevance of the precautionary principle for risk evaluation and its implications for the risk assessment framework.

Based on the analysis of these problems, a transparent, consistent and rational procedure for risk assessment is suggested to facilitate a risk characterization which better meets the demands of policy making and the public for an appropriate risk evaluation.     

Outsourcing of Unionized Firms and the Impact of Labor Market Policy Reforms

This paper shows that outsourcing of parts of the workforce in unionized firms leads to wage moderation both in the case of strategic and flexible outsourcing. As long as the share of the outsourced workforce is not too large, this wage‐moderation effect on domestic employment outweighs the direct substitution effect so that domestic employment increases in unionized firms as outsourcing costs fall. With respect to the impact of labor tax reform changes in the wage tax rate, the tax exemption and the unemployment benefit payments affect domestic wage setting in the same way as in the absence of outsourcing. Furthermore, increasing the degree of tax progression by keeping the relative tax burden per worker constant continues to be good for employment. However, except for low outsourcing activities, the impact of these policy measures will become smaller as outsourcing costs fall.
