Robust Comparisons of Malnutrition in Developing Countries
Authors:David E Sahn  & David C Stifel
Institution:Cornell University
Abstract:We use Demographic and Health Surveys (DHS) to make international and inter–temporal welfare comparisons. While most poverty analyses rely on expenditures or income, we use anthropometric measures of nutrition as indicators of living standards. The advantages are that we observe individual—not household—well–being, deflators and exchange rates are unnecessary, and measurement techniques are similar across surveys. We test the robustness of the headcount results, and find that applying higher order Foster–Greer–Thorbecke poverty measures adds little information; although stochastic dominance testing of nutrition distributions reveals that changes in malnutrition are sensitive to the choice of the "nutrition poverty line."
Keywords:DHS  nutrition  poverty  stochastic dominance  welfare dynamics
