Due to the dramatic ageing of the population, the German welfare state expects enormous challenges in the decades until 2060: either the contribution rates have to be increased by a full 20 percentage points, or the benefits must be cut by one-third – relative to their present growth path. Moreover, even in the otherwise copious German welfare state, the system of publicly financed long-term care benefits is characterized by a considerable coverage gap. In this paper, we analyze past and current reforms of the German financing system for LTC expenditures, and we argue that the coverage gap should be reduced by supplementing the welfare state with an element of mandatory funding. The financial crisis should not induce policy makers to default on this necessary financing reform. 相似文献

A general, copula-based framework for measuring the dependence among financial time series is presented. Particular emphasis is placed on multivariate conditional Spearman's rho (MCS), a new measure of multivariate conditional dependence that describes the association between large or extreme negative returns—so-called tail dependence. We demonstrate that MCS has a number of advantages over conventional measures of tail dependence, both in theory and in practical applications. In the analysis of univariate financial series, data are filtered to remove temporal dependence as a matter of routine. We show that standard filtering procedures may strongly influence the conclusions drawn concerning tail dependence. We give empirical applications to two large data sets of high-frequency asset returns. Our results have immediate implications for portfolio risk management, derivative pricing and portfolio selection. In this context we address portfolio tail diversification and tail hedging. Amongst other aspects, it is shown that the proposed modeling framework improves the estimation of portfolio risk measures such as the value at risk. 相似文献

Compared to other Western European countries, Germany has taken considerable steps to improve the sustainability of financing its public pension system. However, more recently we have observed attempts to revoke some of the enacted reforms before their implementation. If the positive correlation between income and life expectancy is taken into account, one can indeed diagnose a discrimination against low-income earners in the present retirement benefit schedule, and this very group will suffer disproportionately from the increase in legal retirement age enacted in 2007. Therefore, to protect the sustainability of the pension system in the political sphere, it may be necessary to modify the schedule in favor of this group. In other words, sustainability and equity of the pension system must go hand in hand. 相似文献

Allowing for Household Preferences in Emission Trading – A Contribution to the Climate Policy Debate
In the context of emission trading it seems to be taken as given that people's preferences can be ignored with respect to the whole process of fixing emission targets and allocating emission permits to polluters. With this paper we want to reopen the debate on how citizens can be involved in this process. We try to show how citizen preferences can be included in the process of pollution control through emission trading. We propose an emission trading system where all emission permits are initially allocated to households who are then allowed to sell them in the permit market or to withhold (at least some of) them in order to reduce total pollution. This proposal tries to overcome the fundamental disadvantage of traditional permit systems which neglect consumer preferences by solely distributing emission permits to producers / polluters. In our system the property right to nature is re-allocated to the households who obtain the opportunity of reducing actual emissions according to their personal preferences by withholding a part or all of the emission permits allotted to them. Such a change in environmental policy would mark a return to the traditional principles of consumer sovereignty by involving households (at least partially) in the social abatement decision process instead of excluding them. Another advantage of admitting households to the TEP market as sellers or buyers of permits is that this increases the number of agents in the permit market and thus significantly reduces the possibilities of strategic market manipulations. 相似文献
