This paper investigates the influence of invariance axioms in the decomposition of observed poverty variations into growth and inequality effects. After a complete and critical review of the invariance axioms suggested in the literature, we show that few information is needed for the ordering of...

The Luxembourg Income Study (now known as LIS) provides public access for research purposes to harmonized unit-record data sets for multiple countries, in addition to providing summary statistics from those data, including poverty and inequality measures. LIS is a well-managed and undeniably...

The assessment of income inequality can be investigated looking at the solution concepts of the cooperative game theory. We propose a multi-factorial decomposition of the Atkinson index by income sources and evaluate it as a cooperative game of the social cost of inequality. This framework...

The interplay of between- and within-country inequality, the relative contribution of each to overall global inequality, and the implications this has for who benefits from recent global growth (and by how much), has become a significant avenue for economic research. Drawing conclusions from...

Demographic disparities between the rates of occurrence of an adverse economic outcome can be observed to be increasing even as general social improvements supposedly lead towards the elimination of the adverse outcome in question. Scanlan (2006) noticed this tendency and developed a...

We propose a characterisation of an aggregate measure of growth that takes into account the initial economic conditions of individuals. Our measure is a weighted average of individual income growth with weights that are decreasing with the rank of the individual in the initial income...

Extending the traditional income poverty concept by multidimensional poverty has been of growing interest within the last years. This paper contributes with an analysis of interdependent multidimensional (IMD) poverty intensity of time and income, which in particular restricts social...

Bennett and Hatzimasoura (2011) derive a new class of poverty measures suitable for ordinal variables. These indices are weighted sums of the population probabilities of attaining each state of the ordinal variable which is below the poverty line. The weights are uniquely determined by the...
