This paper deals with some problems in the measurement of inequality when negative incomes are allowed. A helpful axiom is defined, called the Greatest Gets More axiom. Using this axiom it can be shown that the properties of some inequality measures depend on whether there are negative incomes...

The Gini index and the Gini mean difference of a univariate distribution are extended to measure the disparity of a general $d$- variate distribution. We propose and investigate two approaches, one based on the distance of the distribution from itself, the other on the volume of a convex set in...

Many developing countries are characterized by a large share of home production. Households allocate their time on both market and non-market activities. The introduction of a tax on labor or capital income induces people to divert from market production to home production. Furthermore, children...

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...

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. We establish two methods to take the sampling error into account. The first one is based...

This paper develops a technique for estimating age- profiles of earnings mobility using conditional kernel density estimation and establishes their statistical inference. Both pointwise and simultaneous confidence intervals are derived. The paper then examines the age- profile of earnings...
