Children's Health & Nutrition, Adult Outcomes & Mobility

描述(由申请者提供)：该项目将汇集、收集和分析孟加拉国的多轮调查数据，利用新获得的小组调查和拟议的额外调查轮，提供关于儿童营养摄入、室内空气污染和健康干预在25年间对长期健康和生产力影响的基于家庭和个人的小组信息。完成的小组调查非常适合调查儿童健康、其他人力资本投资、成人生产力的重要方面、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由于许多现有调查中两个主要选择性来源造成的偏差：个人相对于空间流动性的选择性和按活动选择对结果衡量的选择性。小组数据集的设计是为了能够从非实验数据中对早期营养和其他健康干预措施对成人结果的影响进行尽可能最佳的估计，当时(I)对儿童的资源分配是在家庭背景下优化父母的选择，(Ii)健康捐赠方面存在未观察到的异质性，以及(Iii)成年人在地理上流动。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)相同个人的多个时间段的信息，(Ii)关于兄弟姐妹(任何年龄)的信息，以及(Iii)关于受访者所在地的信息。这些分析还将揭示污染暴露和营养之间的相互关系及其对儿童和成人健康的影响，这些方面在大多数文献中都没有，因为没有注意到健康的异质性和数据不足。

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.
