If one looks at environmental quality N as a renewable natural resource (with its own natural dynamics) which is changed by emissions Z, then one gets a better understanding of the shape of the damage function. In the case of a logistic growth dynamics one obtains a well-shaped transformation frontier N(Z), even in a two-species natural dynamics. For a more general natural interaction in the framework of a prey-predator model one obtains the possibilities of a cusp catastrophe which makes the transformation frontier N(Z) ill-shaped for the standard arguments of economists and their most favoured environmental policy instruments. 相似文献

Borda's vote method was used by the French Academy from 1796 to 1803 when Napoleon got it abolished. In the laws and regulations
of the Academy there are stipulations regarding the election of new members. The practice is demonstrated by some examples
from the protocols.
In fact, Borda presented two vote methods which he showed would give the same conclusion. The method which has not been in
the limelight proves to be the same one as is used for selecting the best player in chess tournaments. 相似文献

It is a known phenomenon that it is difficult to make organizational changes within professional organizations. One recurring observation and experience from health care studies is that it is difficult to discuss the last organizational change with professionals because the most recent change is always perceived as the worst. In order to avoid this routine response, the authors of this article asked 56 senior physicians from the Swedish health care sector what their ideal organization looks like. The authors note that there is a strong institutionalized idea among the physicians of how health care should be organized. The image is not particularly complicated: the organization should be based on the meeting between doctor and patient. One conclusion in the article is that professionals dislike change, but nevertheless, they still want it. Actual change is not the problem – only changes that are not in compliance with the professionals' opinions of organization and management. 相似文献

Faced with a record level of unemployment, the present debate in Germany is to extend the weekly hours of work. In this paper the employment effects of an economy-wide increase in weekly hours are quantified on the basis of a computable general equilibrium model for different specifications of the wage setting rule and the use of additional policy-induced public income. The simulation results back the argument of the opponents of longer working time that not more jobs will be created. However, when the higher tax revenues from GDP growth are used to reduce social security contributions, then the claim of the proponents that more jobs will be created can be supported. 相似文献
