Links between Maternal Employment and Child Nutrition in Rural Tanzania
利用坦桑尼亚农村农户面板数据，研究发现母亲非农就业与儿童身高年龄Z评分呈非线性关系，低劳动供给时负相关，高劳动供给时正相关，极高时又转负；农业就业关联不显著。
Improving child nutrition and empowering women are two important and closely connected development goals. Fostering female employment is often seen as an avenue to serve both these goals, especially if it helps to empower the mothers of undernourished children. However, maternal employment can influence child nutrition through different mechanisms, and the net effect may not necessarily be positive. We develop a theoretical model to show that maternal employment can affect child nutrition through changes in income, intrahousehold bargaining power, and time available for childcare. The links are analyzed empirically using panel data from farm households in rural Tanzania. We find that the links between maternal employment and child height‐for‐age Z‐scores (HAZ) are non‐linear. Off‐farm employment is negatively associated with child HAZ at low levels of labor supply. The association turns positive at higher levels of labor supply and negative again at very high levels. The associations between maternal on‐farm work and child nutrition are weaker and not statistically significant. These findings can help to better design development interventions that foster synergies and avoid potential tradeoffs between female empowerment and child nutrition goals.
