Besonders in der betriebswirtschaftlich relevanten Marktanalyse besteht ein großer Bedarf an möglichst einfachen Prognoseverfahren z. B. in Form von endogenen, d. h. alleine von der Zeit abhängigen, Wachstumsfunktionen. Der hier vorgestellte Test dient dazu, diejenigen Funktionen...

In case of estimating growth curves nonparametrically onc faces the fact that the data driven bandwidth selectors published in standard textbooks mostly choose bandwidths much too low. This is due to the positive autocorrelation observed in growth data. This paper introduces an easy way to...

This paper investigates the concentration in the Swedish and Finnish insurance market. It considers the development of concentration over time and the differences between the two countries. The insurance industry is divided into life and non-life insurance companies. The concentration is...

Im Bereich der Messung der Änderung von Ungleichheit sind schon einige Maße vorgeschlagen worden. Doch bis jetzt hat noch niemand versucht, auf Grundlage von bestimmten Axiomen eine Klasse von dynamischen Ungleichheitsmaßen herzuleiten. Dies geschieht in dieser Arbeit. Nach der Definition der...

Most empirical studies on poverty consider the extent of poverty either for the entire society or for separate groups like elderly people.However, these papers do not show what the situation looks like for persons of a certain age. In this paper poverty measures depending on age are derived...

This paper deals with nonparametric inference for second order stochastic dominance of two random variables. If their distribution functions are unknown they have to be inferred from observed realizations. Thus, any results on stochastic dominance are in uenced by sampling errors. We establish...
