The compulsory health insurance fund in Germany is under huge cost pressure. The reasons are the demographic development and the proceeding medical-technical progress, which keep raising the expenses instead of reducing them. Seeing that financial means are getting scarce, there are multifaceted appendages of rationing the medical supply. New market potential arises, however, for the economy of private health insurance for which one can develop and offer answers. The contribution scetches which economic boarders the private health insurance needs to adhere to. 相似文献

Recycling of packaging material has become more or less mandatory in many European countries, including Norway. Through so-called voluntary agreements quantitative targets are set for the proportion of total waste to be recycled. At the same time the strategic objective for Norwegian waste policy is that there should be a socio-economic balance between different waste treatment options. On the basis of a cost-benefit analysis it is questioned whether the Norwegian recycling policy for liquid board containers really is cost-effective. The calculations show that the net social costs of the recycling system in 1999 amounted to EUR3.5 million. The high cost is due to the fact that these containers constitute a small fraction of total waste from the household and that it is costly to separate it from other waste. The environmental costs from landfilling or incineration are small compared to the costs of recycling. The best alternative, according to our analysis, is to incinerate the containers with energy recovery. 相似文献

In this paper we illustrate how certain design problems can be simplified by reparametrization of the response function. This alternative viewpoint provides further insights than the more traditional approaches, like minimax, Bayesian or sequential techniques. It will also improve a practitioner’s understanding of more general situations and their “classical” treatment. 相似文献

Designing and managing a company's specific landscape and its business processes has been identified as a great challenge for several years. Business processes are highly dynamic and distributed and can only rarely be planned, modeled and analyzed completely. For a computer-aided business process system, which supports the designing and managing process, first of all a powerful uniform formalism is necessary, where all necessary knowledge concerning company's and its processes can be represented. In this paper we will concentrate on the introduction of such a formal methodology to describe business processes, company organization structures and information technology structures in one uniform formalism. The ideas we use are mainly based on methods from graph grammars, process management, Artificial Intelligence and business process (re)engineering. 相似文献

Money Growth Volatility and the Demand for Money in Germany: Friedman’s Volatility Hypothesis Revisited. — Recently, the Bundesbank claimed that monetary targeting has become considerably more difficult by the increased volatility of short-term money growth. The present paper investigates the impact of German money growth volatility on income velocity and money demand in view of Friedman’s money growth volatility hypothesis. Granger-causality tests provide some evidence for a velocity/volatility linkage. However, the estimation of volatility-augmented money demand functions reveals that — in contrast to Friedman’s hypothesis — increased money growth volatility lowered the demand for money. 相似文献

Encouraged by a highly expansionary economic policy, the global economy is enjoying a rapid upturn. Utilisation of capacity is high in many sectors, particularly in the growth centres of the USA and East Asia, where China leads the field. With inflationary risks on the increase, most countries are now shifting the focus of economic policy. Fiscal policy in particular can be expected to provide little in the way of further stimulus. In addition, there has been a turnaround in interest rates in many countries. Yet how quickly can the monetary reins be tightened without jeopardising growth or endangering price stability? 相似文献
