On ne sait pas dans quelle mesure les indicateurs de bien-être social résultent de différences de prix plutôt que de différences saisonnières et géographiques de niveaux de vie entre ménages. A partir de données du Rwanda en 1983, nous montrons que le changement de la mesure du niveau...

We show under lognormality that, when the Gini coefficient is stable over time, defining the poverty line as a fraction of a central tendency of the living standard distribution restricts the evolution of the poverty measures to be stable. That is, poverty does not change if the Gini coefficient...

This paper makes an assessment of Nepalese poverty situation during 1977 - 1997 using a comparative static approach. Income and human poverty indices have been estimated using World Bank and UNDP methods, respectively. Moreover, it also makes exploratory analysis to study the causes and nature...

(english) It is not known to what extent welfare measures result from seasonal and geographical price differences rather than from differences in living standards across households. Using data from Rwanda in 1983, we show that the change in mean living standard indicators caused by local and...

We derive a parametric formula of the Watts' poverty index for the bivariate lognormal distribution of price indices and nominal living standards. This enables us to analyze the contributions of price and nominal living standard distributions to poverty, to estimate poverty when only means and...

It is not known to what extent welfare measures result from seasonal and geographical price differences rather than from differences in living standards across households. Using data from Rwanda in 1983, we show that the change in mean living standard indicators caused by local and seasonal...

This paper proposes a measure of the contribution of unequal opportunities to earnings inequality. Drawing on the distinction between ‘circumstance’ and ‘effort’ variables in John Roemer’s work on equality of opportunity, we associate inequality of opportunities with five observed...

It is not known to what extent welfare measures result from seasonal and geographical price differences rather than from differences in living standards across households. Using data from Rwanda in 1983, we show that the change in mean living standard indicators caused by local and seasonal...

Spatial price dispersion varies because of climatic fluctuations, marketimperfections, economic growth or economic policies. These variations areoften neglected in poverty studies.In this paper, we propose a simple simulation formula to assess the effecton poverty of a change in the spatial mean...

The Poverty Wars started with a coordinated series of skirmishes by the Centre for Independent Studies. One of their main criticism of income-based measures of poverty is that measurement error(i.e. under-reporting) is pronounced for low income earners, especially those who indicate they have an...
