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 suggests a method of depicting mobility processes of income or earnings. It makes use of nonparametric quantile regression based on bivariate kernel density estimation. The method is illustrated with a comparison of German and US income mobility. --

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...

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...

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 reviews various mobility measures and establishes their asymptotic sampling distribution. The paper then examines the development of earnings mobility for both sexes in Germany between 1983 and 1991 using the Socio-Economic Panel. --
