Die vom Bundesrat angestrebte Senkung der Pflichtreserven der Krankenversicherer nimmt ein grösseres Risiko für einen allfälligen Konkurs in Kauf als bisher. Ein statistisch gesehen zu grosses Risiko, wie der Autor des folgenden Beitrags meint, der darlegt, dass damit künftig
mit zwei Konkursen pro Jahr gerechnet werden müsste.

A betweenness axiom states that if A and B are equally good then a mixture of A and B is equally good as well. This note demonstrates that the violations of the betweenness axiom documented in several experimental studies can be alternatively attributed to the effect of random errors.

Recently, the problems associated with the existing journal review processnaroused discussions from seasoned management researchers, who have also made useful suggestions for improving the process. To complement these suggestions, we propose a more radical change: a manuscript should be reviewed on an “as is”nbasis and its fate be determined in one round of review. The as-is review...

This chapter discusses the role of environmental morale and environmental motivation in individual behavior from the point of view of economics and psychology. It deals with the fundamental public good problem, and presents empirical (laboratory and field) evidence on how the cooperation problem can be overcome. Four different theoretical approaches are distinguished according to how...

In this article, the authors develop and test hypotheses relating the four knowledge creation modes of socialization, externalization, combination, and internalization as performed during the concept and the development phases of new product development projects to new product success. Using data from 94 new product development projects, they find that socialization during the...

In this paper we present a two period model, where the agent'snpreferences are described by prospect theory as proposed by Kahneman and Tversky. We solve for the agent's portfolio decision. Our findings are that the changes in portfolio weights depend crucially on the reference point and the ratio between the reference point and the current wealth, and thus only indirectly...

It has often been pointed out in the literature that a symbiotic relationship exists betweennterrorist groups and the media. As yet, however, no formal model has been built based on thisnissue and only very little empirical research has been done in this field. The presentncontribution builds a simple game theoretic model, focussing on the social interactionsnbetween terrorists and...

This paper studies if the consumption-based asset pricing model can explain the cross-section of expected returns. The CRRA model and several refinements (habit persistence and idiosyncratic shocks) all imply that the conditional expected return is linearly increasing in the asset's conditional covariance with consumption growth. Results from quarterly data on the 25 Fama-French...
