A particular shortcoming of panel surveys is potential bias arising from selective attrition. Based on data from the German Socio-Economic Panel Study (SOEP) we analyze potential artifacts (level, structure, inequality of income) by comparing results from two independently drawn panel...

<Para ID="Par1">Gini’s mean difference has decomposition properties that nest the decomposition of the variance as a special case. By using it is possible to reveal some of the implicit assumptions imposed on the data by using the variance. I argue that some of those implicit assumptions can be traced to be...</para>

The aim of this paper is to implement distributional considerations in comparing the economic well-being of individuals over time and living in different regions in Italy. Both Absolute Lorenz Curves (ALC) and standard Lorenz curves are used to address this issue from both a national and...

In this paper we illustrate the potential use of an old/new methodology which combines the use of concentration curves in order to investigate the components that make up a regression coefficient. The illustration is based on examining gender differences in the effect of age on labor market...

We suggest graphical tools that indicate whether the relationship between variables in regression is monotonic. If not, the tools identify sections with different signs and inform on possibilities and types of monotonic transformations that can change the sign of the coefficient.

Stochastic dominance rules provide necessary and sufficient conditions for characterizing efficient portfolios that suit all expected utility maximizers. For the finance practitioner, though, these conditions are not easy to apply or interpret. Portfolio selection models like the mean-variance...
