Using panel data from Rwanda, we estimate seasonal transient and chronic poverty indices, for different poverty lines, poverty indicators, equivalence scales, and with and without corrections for price variability and for the sampling scheme. We also estimate sampling standard errors for the poverty indices. The worst poverty crises occur after the dry season at the end of the year. Most of the...

FOR MANY YEARS, poverty in urban areas of Africa, Asia, Latin America and the Caribbean has been identified by spatial area (e.g. settlement, neighbourhood, inner city) as often as it has been referred to by social group (e.g. low-income women, the homeless). This has perhaps given inadequate recognition to poverty differentiation within urban poor groups or, to put it another way, it has contr...

Recent studies have shown the value of mobile phone data to tackle problems related to economic development and humanitarian action. In this research, we assess the suitability of indicators derived from mobile phone data as a proxy for food security indicators. We compare the measures extracted from call detail records and airtime credit purchases to the results of a nationwide household surve...

The share of household resources devoted to children is hard to identify, because consumption is measured at the household level, and goods can be shared. Using semiparametric restrictions on individual preferences within a collective model, we identify how total household resources are divided up among household members, by observing how each family member's expenditures on a single private go...

This paper concerns with rank-dependent poverty measures and shows that an ordered weighted averaging, hereafter OWA, operator is underlying in the definition of these indices. The dual decomposition of an OWA operator into the self-dual core and the anti-self-dual remainder allows us to propose a decomposition for all the rank-dependent poverty measures in terms of incidence, intensity and ine...

BACKGROUND Epidemiological and clinical studies in high income countries have suggested that Helicobacter pylori (H. pylori) may cause anaemia, but evidence is lacking from low income countries.We examined associations between H. pylori infection in early childhood and anaemia at the age of 6.5 years in an Ethiopian birth cohort. METHODS In 2011/12, 856 children (85.1 % of the 1006 original s...

Results and Discussions Poverty Status At the time of independence, the country faced twin nutritional problems threat of famine and acute starvation, and chronic under nutrition. Former existed due to the lack of national and regional food security systems. The latte...

Most welfare studies are based on the assumption that wellbeing is monotonically related to the variables used for the analysis. While this assumption can be regarded as reasonable for many dimensions of wellbeing like income, education, or empowerment, there are some cases where it is definitively not relevant, in particular with respect to health. For instance, health status is often proxied ...
