Genetic algorithms (GAs) are appropriate when investors have the objective of obtaining mean.variance (VaR) efficient frontier as minimising VaR leads to non.convex and non.differential risk.return optimisation problems. However GAs are a time.consuming optimisation technique. In this paper, we...

This article provides a tool to study over time the distributions of income in a population, regardless the irregular distribution of data. We even approach Lorenz curves at the times when we lack the required data. Finally we apply the present technique to a European country where inequalities...
