Whose Fast and Whose Feast? Intrahousehold Asymmetries in Dietary Diversity Response Among East African Pastoralists
研究东非牧民家庭内部不同成员在膳食多样性上的收入弹性差异，发现户主在低收入时承担更多营养负担，而其他成员在高收入时获益更多，传统对称假设会掩盖这种不对称行为。
This article explores intrahousehold dietary diversity allocation within pastoralist households in eastern Africa. We estimate income elasticities of dietary diversity for demographic cohorts allowing asymmetric behavior depending on household circumstances. We find that household heads disproportionately bear the nutritional burden when household income is below mean, while other cohorts disproportionately enjoy the nutritional gains when it is above mean. The commonly assumed symmetric framework masks this intrahousehold behavior and produces biased elasticity estimates. Stochastic dominance tests show adult daughters as better‐off than other household members in their dietary diversity, sons as worse off, and little difference between male heads and their wives.
