Composition of Household Income and Child Nutrition Outcomes Evidence from Uganda
利用乌干达全国面板调查数据，研究家庭总收入及不同来源收入（如工资、非农自营、农业收入）对儿童身高别年龄Z评分的影响，发现总收入短期变化无显著影响，但非农自营收入比例与儿童营养正相关，而农业收入中自产消费和低蛋白作物收入比例有负效应。
This study targets the empirical space between cross-country analyses exploring links between income and nutrition without insights on micro-level determinants, and relevant microeconomic studies hindered by small sample size and/or incomplete data. We use the rural samples of the three waves of the Uganda National Panel Survey, and estimate panel regressions of child height-for-age z -scores (HAZ) controlling for time-invariant child-level heterogeneity. On the whole, we find no impact of short-term changes in total gross income on HAZ but document small positive correlations for younger children. Sector-differentiated analyses indicate that compared to wage earnings, only share of income from non-farm self-employment correlates positively with HAZ. Within agriculture, shares of income from consumption of own crop production and from low-protein crop production underlie the negative effect of share of income from crop production. While we cannot claim causal relationships, our findings suggest the possibility of “stickiness” of crop production to own consumption.
