At present, our society and its social security system are not prepared to cope with the challenges resulting from the continuous increase of life expectancy. The traditional concept of disease has to be modified for serving the special needs of the elderly. The optimistic compression of disease theory is an intriguing model, but lacks prove by available data. The anti-aging boom diverts the focus from the social and financial burden that will be unevitably caused by long-term care in the future. If there will not be an — up to now unforeseeable — breakthrough in research, particularly dementia will have an enormous impact on social cost which is often underestimated. 相似文献

We argue that the stakeholder perspective on corporate social responsibility is in the process of being enlarged. Due to the process of institutional isomorphism, corporations are increasingly adopting organizational features designed to promote proactivity over mere reactivity in their stakeholder relationships. We identify two sources of pressure promoting the emergence of the proactive corporation -- stakeholder activism and the recognition of the social embeddedness of the economy. The final section describes four organizational design dimensions being installed by the more proactive corporations today -- cooperation, participation, negotiation, and direct anticipation. 相似文献

The Effect of Communication Media on Cooperation 总被引:1,自引:0,他引:1
Abstract. We examine how communication affects cooperation with the help of seven standard public goods experiments that only differ with respect to the medium of pre‐play communication. Our treatments include bidirectional and unidirectional communication via (mostly electronic) auditory and/or visual channels. The results suggest that successful cooperation is attributable to the opportunity of ‘coordinating’ behavior in the communication phase. Furthermore, both the level and the stability of cooperation significantly interact with the communication medium, even though the content of communication is remarkably similar across the communication treatments. 相似文献

Experiments in Environmental Economics and Some Close Relatives 总被引:2,自引:0,他引:2
Abstract. It is not only the great number of papers written on environment economics that make it worth dealing with this special branch of experimental research, but the environmental problem in all its facets seems to serve as a catalyst for identifying some methodological problems of the experimental method. For this reason, we will not only try to give an overview of recent experiments in environmental economics but also add some thoughts on the methodological implications of this work. We identify three direct connecting factors for the experimental method and environmental economics. First, social dilemmas are, in many cases, at the core of environmental problems. Experiments are able to test theoretical hypotheses for individual behavior in such social dilemma situations. The second connecting factor comes from the field of applied experimental work and can be characterized as the testbedding of institutional arrangements for the solution of environmental problems. The last direct application of experimental methods to environmental economics concerns the individual evaluation of environmental resources. 相似文献

Pension Reform, Capital Markets and the Rate of Return 总被引:1,自引:0,他引:1

Abstract. This paper discusses the consequences of population aging and a fundamental pension reform – that is, a shift towards more pre‐funding – for capital markets in Germany. We use a stylized closed‐economy, overlapping‐generations model to compare the effects of the recent German pension reform with those of a more decisive reform that would freeze the current pay‐as‐you‐go contribution rate and thus result in a larger funded component of the pension system. We predict rates of return to capital under both reform scenarios over a long horizon, taking demographic projections as given. Our main finding is that the future decrease in the rate of return is much smaller than often claimed in the public debate. Our simulations show that the capital stock will decrease once the baby‐boom generations enter retirement, even if there were no fundamental pension reform. The corresponding decrease in the rate of return, the direct effect of population aging, is around 0.7 percentage points. While the capital market effects of the recent German pension reform are marginal, the rate of return to capital would decrease by an additional 0.5 percentage points under the more decisive reform proposal. 相似文献

This article uses a tailor-made new data set of 7 580 251 observations for German exports at the firm-product-destination level to estimate a gravity equation and to investigate the link between the amount of firms’ exports and the distance to destination countries. It is shown that, in line with stylized facts based on aggregate data, the quantity of exports declines significantly with distance within a firm for a given product. 相似文献
