The Mean-Variance (MV) is the most popular methodology for constructing portfolios. However, it is not consistent with the expected utility hypothesis, unless one assumes the strong assumptions of either a quadratic utility or normally distributed asset returns. The Mean-Gini (MG) is an...

The aim of this paper is to suggest a new, nonparametric multiple regression method, based on the Extended Gini (EG) measures of dispersion, which enables the user to follow the curvature of the regression curve. The method is capable of estimating a series of linear approximations of the...

The aim of this paper is to empirically evaluate the effect of the length of the accounting period on indices of inequality of household income in Israel. There are three main findings: (1) The analysis of the impact of the account period on the Gini index of inequality can be done in a way...

A nonparametric multiple regression method, based on the extended Gini that depends on one parameter, v, is investigated. The parameter v enables production of infinite alternative linear approximations to the regression curve which differ in the weighting schemes applied to the slopes of the...
