Income mobility is often thought to equalize permanent incomes and thereby to improve social welfare. The welfare analysis of mobility often fails, however, to account for the cost of the variability of periodic incomes around permanent incomes. This paper assesses the net welfare benefit of...

Previous child health evidence in Kenya has been based on uni-dimensional poverty analysis. Assessing the multiple aspects of child well-being can help, however, reveal complexities and ambiguities in the distribution of child well-being. This paper analyses multidimensional aspects of child...

This paper explores the link between poverty and inequality through an analysis of the poverty impact of changes in income-component inequality and in between -an within- group inequality. This can help shed light on the theoretical and empirical linkages between poverty, growth and inequality....

This paper proposes techniques to test whether growth has been pro-poor. We first review different definitions of pro-poorness and argue for the use of methods that can generate results that are robust over classes of pro-poor measures and ranges of poverty lines. We then provide statistical...

DAD is designed to facilitate the analysis and the comparisons of social welfare, inequality, poverty and equity across distributions of living standards and using disaggregated data. It is freely distributed. DAD's features include the estimation of a large number of indices and curves that are...
