Flexibility of Household Structure: Child Fostering Decisions in Burkina Faso
利用非洲实地数据，研究家庭如何通过儿童寄养（将孩子暂时送到其他家庭生活）来调整规模，发现收入冲击、子女性别失衡、离小学远、有更多优质社交网络成员的家庭更可能送养孩子。
Using data I collected in Africa, this paper examines a household's decision to adjust its size through child fostering, an institution where biological parents temporarily send children to live with other families. Households experiencing negative idiosyncratic income shocks, child gender imbalances, located further from primary schools, or with more "good" quality network members (fewer subsistence farmers and unmarried individuals and more educated members) are significantly more likely to send a child. Results reject an overall symmetric fostering model across senders and receivers, but evidence of symmetry is found when the test is restricted to exogenous income shocks and gender imbalances.
