| Longitudinal household data can have considerable advantages over much more widely used cross-sectional data. The collection of longitudinal data, however, may be difficult and expensive. One problem that has concerned many analysts is that sample attrition may make the interpretation of estimates problematic. Such attrition may be particularly severe in areas where there is considerable mobility because of migration between rural and urban areas. Many analysts share the intuition that attrition is likely to be selective on characteristics such as schooling and that high attrition is likely to bias estimates made from longitudinal data. This paper considers the extent of and implications of attrition for three longitudinal household surveys from Bolivia,... |

| Over the past decades child stunting in Ethiopia has persisted at alarming rates. While the country experienced several droughts during this period, it also received enormous amounts of food aid, leading some to question the effectiveness of food aid in reducing child malnutrition. Using nationally representative household surveys from 1995-96 and controlling for program placement, we find that children between 6 and 24 months experienced about 0.9 cm less growth over a six-month period in communities where half the crop area was damaged compared to those without crop damage. Food aid was also found to have a substantial effect on growth of children in this age group. Moreover, on average the total amount of food aid appeared to be sufficient to... |

| Reducing food insecurity in the developing world continues to be a major public policy challenge, and one that is complicated by lack of information on the location, severity, and causes of food insecurity. Such information is needed to properly target assistance, evaluate whether progress is achieved, and develop appropriate interventions to help those in need. This research report explores a new method of measuring food insecurity using food data collected as part of household expenditure surveys. Such surveys are routinely undertaken by numerous national governments throughout the developing world, but in the past the resulting food data remained largely unexploited for the purposes of measuring food insecurity. Using data from 12 Sub-Saharan African... |

| How rapidly will child undernutrition respond to income growth? This study explores that question using household survey data from 12 countries. In addition, data on the undernutrition rates since the 1970s available from a cross-section of countries are employed in this investigation. Both forms of analysis yield similar results. Income increases at household and national levels imply similar rates of reduction in undernutrition. Using these estimates and better-than-historical income growth rates, we find that the Millennium Development Goal (MDG) of halving the levels of child underweight by 2015 is unlikely to be met through income growth alone. What is needed is a balanced strategy of income growth and investment in more direct interventions to... |

| This paper examines the impact of preschool malnutrition on subsequent human capital formation in rural Zimbabwe using a maternal fixed effects-instrumental variables (MFE-IV) estimator with a long-term panel data set. Representations of civil war and drought "shocks" are used to identify differences in preschool nutritional status across siblings. Improvements in height-for-age in preschoolers are associated with increased height as a young adult and number of grades of schooling completed. Had the median preschool child in this sample had the stature of a median child in a developed country, by adolescence, she would be 4.6 centimeters taller and would have completed an additional 0.7 grades of schooling. |

| Designing strategies and policies that will alleviate poverty and improve household food security and nutritional well being is one of the most important challenges facing government policymakers in developing countries. The choice of strategies and policies depends in large part on understanding the dynamics of poverty, especially the mechanisms by which households acquire and spend income and cope with cries such as poor harvest or loss of employment. This work by Harold Alderman and Marito Gracia represents IFPRI's first comprehensive analysis of the longitudinal data on 800 households collected between 1986 and 1989 in Pakistan. This unique data set enables researchers to examine the temporal dimensions of food security, income and labor dynamics,... |

| Within many African households, agricultural production is simultaneously carried out on many plots controlled by different members of the household. Detailed plot-level agronomic data from Burkina Faso provides striking evidence of inefficiencies in the allocation of factors of production across the plots controlled by different members of the household. Production function estimates imply that the value of household output could be increased by 10 to 20 percent by reallocating currently-used factors of production across plots. This finding contradicts standard models of agricultural households. A richer model of behavior, which recognizes that the individuals who comprise a household compete as well as cooperate, has important implications for the... |
