We examine the measurement of individual poverty in an intertemporal context. Our aim is to capture the importance of persistence in a state of poverty and we characterize a corresponding individual intertemporal poverty measure. Our first axiom requires that intertemporal poverty is identical...

This paper demonstrates that the property of 'replication invariance', generally considered to be an innocuous requirement for the extension of fixed-population poverty comparisons to variable-population contexts, is incompatible with other plausible variable- and fixed-population axioms. --...

Tracking poverty is predicated on the availability of comparable consumption data and reliable price deflators. However, regular series of strictly comparable data are only rarely available. Poverty prediction methods that track consumption correlates as opposed to consumption itself have been...

Debates about poverty relief and foreign aid often hinge on claims about how many poor people there are in the world and what constitutes poverty. Good measures of poverty are essential for addressing the world poverty problem. Measures of poverty require a basis for determining who is poor and...

This paper reviews the pattern of poverty rates and income inequality in El Salvador since the 1990s. It discusses some of the likely factors that explain the reduction in income inequality that has taken place in the country in the last decade, which paradoxically has coincided with the long...

Since 1994, a great deal has been accomplished. We argue that poverty reduction was temporarily sidelined in the 2000s. A series of shocks, especially the fuel and food price crisis of 2008, combined with poor productivity growth in agriculture and a weather shock, undermined progress in...

In order to understand whether a reduction in overall poverty has improved the situations of the poorest, it is crucial to distinguish them from the moderately poor population. In this paper, we explore the mechanisms to distinguish subsets of the poor in a multidimensional counting framework....

The majority of the world's poor, by income poverty and multi-dimensional poverty, now live in countries officially classified by the World Bank as middle-income countries. Of course nothing happens when a country crosses a (somewhat) arbitrary threshold in per capita income but it does matter...

Aid is not generally aimed at the poorest people, though most multilateral or bilateral agencies would like to think they get included. However, donors’ strategies are generally blind to differentiation among the poor, and have not improved in this respect. The special provisions for the least...

Local institutional and structural (meso) factors can play a role in mediating the returns to a macro-social policy. I focus on the Brazilian cash-transfer-programme Bolsa Familia and check how contextual features influence the returns to transfers. Building on Amartya Sen's work, I assess the...
