In this article we provide an overview of the Gini decomposition and the generalized entropy inequality measures, a free access to their computation, an application on French wages, and a different way than Dagum to demonstrate that the Gini index is a more convenient measure than those issued...

Les mesures d’inégalité du revenu rassemblent deux types d’indicateurs décomposables : les indices décomposables en sous-populations et les indices décomposables en sources de revenu. Les premiers permettent de partager l’inégalité totale en une inégalité intragroupe et une...

We study the probability of rejecting the seasonal unit root tests developed by Hylleberg et al. when they are applied to fractionally integrated seasonal time series. We find that these tests have quite low power and that they lead to a risk of over-differencing. The forecasting performance of...

Gini and entropy are the most use measures to gauge income inequalities. We show that each measure yields different subgroup decomposition techniques into within-group inequalities and between-group inequalities. Then, we show that the Gini index has been decomposed into many ways to bring out a...

The purpose of this paper is to extend Dagum’s Gini decomposition (“A New Approach to the Decomposition of the Gini Income Inequality Ratio”, Empirical Economics 22(4), 515-531, 1997a) following three types of theoretical modelisation. The first one deals with a “poor/non-poor”...

La loi de probabilité des indices décomposés de pauvreté, établis sur la théorie des ensembles flous, est inconnue. Comme le calcul des contributions est normalisée et bornée dans [0,1], les changements dans les indices concernent des valeurs très petites et il est difficile de conclure...

Cet article analyse le comportement cyclique du cours du Dow Jones et notamment ses propriétés de mémoire longue à travers une nouvelle classe de modèles ARFIMA semiparamétriques avec erreurs GARCH hyperboliques, notée SEMIFARMA-HYGARCH ; cette classe inclut une tendance déterministe non...
