Classical inequality indices, welfare functions, and the dual decomposition

Aristondo, Oihana; García-Lapres, José Luis; Vega, … - Society for the Study of Economic Inequality - ECINEQ - 2012

We consider the classical inequality measures due to Gini, Bonferroni, and De Vergottini and we present a brief review of the three inequality indices and the associated welfare functions, in the correspondence scheme introduced by Blackorby and Donaldson, and Weymark. The three classical...

A New Multiplicative Decomposition For The Foster-Greer-Thorbecke Poverty Indices

Aristondo, Oihana; Vega, Casilda Lasso de la; Urrutia, Ana - Society for the Study of Economic Inequality - ECINEQ - 2008

This paper identifies a multiplicative decomposition for the Foster-Greer-Thorbecke poverty indices as a product of the … three components which should be involved in every poverty index: the incidence of poverty, measured by the headcount ratio …, the intensity of poverty, measured by the aggregate income gap ratio and the inequality among the poor measured by an …

On the measurement of long-term income inequality and income mobility

Aaberge, Rolf; Mogstad, Magne - Society for the Study of Economic Inequality - ECINEQ - 2010

This paper proposes a two-step aggregation method for measuring long-term income inequality and income mobility, where mobility is defined as an equalizer of long-term income. The first step consists of aggregating the income stream of each individual into a measure of permanent income, which...

Measuring long-term inequality of opportunity

Aaberge, Rolf; Mogstad, Magne; Peragine, Vito - Society for the Study of Economic Inequality - ECINEQ - 2010

In this paper, we introduce and apply a general framework for evaluating long-term income distributions according to the Equality of Opportunity principle. Our framework allows for both an exante and an ex-post approach to EOp. Our ex-post approach relies on a permanent income measure defined as...

Robust inequality comparisons

Aaberge, Rolf; Mogstad, Magne - Society for the Study of Economic Inequality - ECINEQ - 2010

This paper is concerned with the problem of ranking Lorenz curves in situations where the Lorenz curves intersect and no unambiguous ranking can be attained without introducing weaker ranking criteria than first-degree Lorenz dominance. To deal with such situations Aaberge (2009) introduced two...
