Children's Health & Nutrition, Adult Outcomes & Mobility

描述（由申请人提供）：本项目将收集、收集和分析来自孟加拉国的多轮调查数据，提供基于家庭和个人的小组信息，说明儿童营养摄入、室内空气污染和25年期间的健康干预措施对健康和生产力的长期影响，使用新的小组调查和拟议的额外调查轮次。完成的小组调查非常适合于调查儿童健康、其他人力资本投资、成人生产力的重要维度、成人健康、移民和婚姻市场结果之间的长期关系，因为调查设计最大限度地减少了许多现有调查中两个主要选择性来源造成的偏差：个体在空间流动性方面的选择性和通过活动选择的结果测量的选择性。小组数据集的设计目的是，在以下情况下，能够根据非实验数据对早期营养和其他健康干预措施对成人结果的影响作出最佳估计：(i)对儿童的资源分配是在家庭背景下由优化父母做出的选择，（ii）健康禀赋存在未观察到的异质性，以及（iii）成年人在地理上是流动的。我们将使用的分析方法将利用数据的三个重要维度的组合：(i)来自同一个人的多个时间段的信息，（ii）兄弟姐妹（任何年龄）的信息，以及（iii）受访者所在地的信息。分析还将揭示污染暴露与营养之间的相互关系及其对儿童和成人健康的影响的各个方面，由于对健康异质性的忽视和数据不足，大多数文献中都没有这些方面。

DESCRIPTION (provided by applicant): This project will assemble, collect and analyze multiple rounds of survey data from Bangladesh, providing family-based and individual panel information on the long-term health and productivity effects of childhood nutritional intakes, indoor air pollution, and health interventions over a 25-year span, using a newly-available panel survey as well as a proposed additional survey round. The completed panel survey is well-suited for investigating the long-term relationships between childhood health, other human capital investments, important dimensions of adult productivity, adult health, migration, and marriage-market outcomes because the survey design minimizes the biases due to two major sources of selectivity in many existing surveys: selectivity of individuals with respect to spatial mobility and selectivity of outcome measures by activity choice. The panel data set has been designed to enable the best estimates possible from non-experimental data of the effects of early nutritional and other health interventions on adult outcomes when (i) resource allocations to children are choices made by optimizing parents within a family context, (ii) there is unobserved heterogeneity in health endowments, and (iii) adults are geographically mobile. The methods of analysis we will use will exploit the combination of three important dimensions of the data: (i) information from multiple time periods for the same individuals, (ii) information on siblings (of any age), and (iii) information on the locations of the respondents. The analyses will also reveal aspects of the interrelationships between pollution exposure and nutrition and their effects on child and adult health that are absent in most of the literature due to inattention to health heterogeneity and inadequate data.
