Two conversion schemes may be employed for assessing income inequality from household equivalent incomes: to weight household units by size or by needs. Using data from the Luxembourg Income Study, we show the sensitivity of country inequality rankings to conversion schemes and explain the...

Allowing victims of natural disaster to migrate can play a critical role in the recovery of the affected country, but the United States has no system that allows for this type of assistance. Victims of natural disasters do not qualify as refugees under U.S. or international law, and migration...

Aphorisms that “rising tides raise all boats” or that material advances of the rich eventually “trickle down” to the poor are really maxims regarding the nature of stochastic processes that underlay the income/wellbeing paths of groups of individuals. This paper looks at the implications...

This paper examines three possible approaches to pro-poor growth. The first one assumes that the poverty line remains constant in real terms over time. The second perspective examines the case where the poverty line is equal to half the median of the income distribution but assumes that such a...

This paper proposes a multidimensional procedure for jointly assessing the absolute and relative pro-poorness of growth. It is also a procedure for testing whether poverty comparisons can be made over classes of indices that incorporate both absolute and relative views of poverty. Besides being...

The most popular general univariate polarization indexes for discrete and continuous variables are extended and combined to describe the extent of polarization between agents in a distribution defined over a collection of many discrete and continuous agent characteristics. A formula for the...

This paper considers the effectiveness and efficiency of global growth, as a route to poverty reduction, since 1990 and then demonstrates the redistributive challenges implicit in various poverty lines and scenarios: the significance being that this historical data can inform understanding and...

While much progress has been made over the last 25 years in measuring global poverty, there are a number of challenges ahead. The paper discusses three sets of problems: (i) how to allow for social effects on welfare, recognizing the identification issues involved; (ii) the need to monitor...

This paper makes new estimates of global poverty and inequality in 2012 using both ‘old', 2005 and ‘new', 2011 purchasing power parity (PPP) price data in order to assess systematically what difference PPP data makes to the estimates. The methodology for the 2011 PPP data is thought to be...

Distributive value judgments based on the ‘origins’ of economic inequalities (e.g. circumstances and responsible choices) are increasingly evoked to argue that ‘the worst form of inequality is to try to make unequal things equal’. However, one may reasonably agree that distributive value...
