Head Start is a comprehensive, early childhood development program designed to augment the human capital and health capital levels of disadvantaged children. Grossman's (1972) health capital model suggests that early investments of this type should have lasting effects on health outcomes. This...

A Unified Approach to Measuring Poverty and Inequality: Theory and Practice is an introduction to the theory and practice of measuring poverty and inequality, as well as a user's guide for analyzing income or consumption distribution for any standard household dataset using the World Bank's...

This paper proposes a new methodology for multidimensional poverty measurement consisting of an identification method ρk that extends the traditional intersection and union approaches, and a class of poverty measures Mα. Our identification step employs two forms of cutoff: one within each...

We recently introduced a general method for measuring poverty when there are multiple dimensions [1,2] and provided a specific cross-country implementation (the MPI) as part of the 2010 Human Development Report [4,11] to complement existing methods. Our recent piece in the Journal of Economic...

Multidimensional measures provide an alternative lens through which poverty may be viewed and understood. In recent work we have attempted to offer a practical approach to identifying the poor and measuring aggregate poverty (Alkire and Foster 2011). As this is quite a departure from traditional...

The variance of logarithms is a widely used inequality measure which is well known to disagree with the Lorenz criterion. Up to now, the extent and likelihood of this inconsistency were thought to be vanishingly small. We find that this view is mistaken : the extent of the disgreement can be...

The Human Development Index (HDI) improves upon per-capita Gross Domestic Product as an indicator of development by incorporating information on health and education. However, like its predecessor, it fails to account for the inequality with which the benefits of development are distributed...

There is a growing interest on dynamic and broader concepts of deprivation such as vulnerability, which takes in to account the destitution of individuals from future shocks. We use the framework of decision making under uncertainty to arrive at a new measure of vulnerability to poverty. We...
