In a public good economy the distribution of initial income is an important determinant of how many individuals contribute to the public good. For the case when all individuals have identical preferences in this paper a simple formula is derived that describes the proportion of all income...

A draft of a reform towards "socially bounded competition" within the health care system indicates, first of all, that several areas of such an insurance system would have to be regulated by the state. Such a reform is much more complicated than text book models or the proposals of various...

In Germany economic experts and politicians are proposing a fundamental reform of the health-care system by which the current wage-dependent contributions are replaced by flat-rate insurance premiums. One major reason behind this proposal is the wish to avoid the distortion effects caused by the...

Lindahl equilibria are often seen as an ideal outcome of cooperation in a public-goods economy. But it has also been observed that, if no transfer payments are possible, the Lindahl equilibrium may not be Pareto-superior to the Nash outcome of the voluntary-contribution game. We derive...

We develop a framework for analyzing national income accounting using a revealed welfare approach that is sufficiently general to cover, e.g., both the standard discounted utilitarian and maximin criteria as special cases. We show that the basic welfare properties of comprehensive national...

The Lindahl equilibrium is mostly motivated by a rather artificial price mechanism. Even though the analogy to a competitive market has been emphasised by Lindahl himself his approach does not directly explain the normative ideas, which are behind this concept. In the present paper we therefore...

In the Dasgupta-Heal-Solow-Stiglitz model of capital accumulation and resource depletion we show the following equivalence: If an efficient path has constant (gross and net of population growth) savings rates, then population growth must be quasi-arithmetic and the path is a maximin or a...
