Feed the children
通过对内罗毕424对已婚夫妇进行实验，研究贫困家庭中关于孩子食物支出的决策过程，发现集体决策模型更符合实际，且女性并不比男性更偏好为孩子花钱。
Abstract To understand the household decision-making process regarding food expenditures for children in poor households in Nairobi, we conduct an experiment with 424 married and monogamous couples. In the experiment, the spouses (individually and jointly) allocate money between themselves and nutritious meals for one of their children. We propose a novel and simple test to distinguish between cooperative/collective and non-cooperative decision behaviour. We find strong empirical support for the collective model of household consumption. This collective model indicates that the spouses’ structural bargaining weights derived from observed consumption patterns strongly correlate with more traditional indicators of power. Furthermore, our results suggest that women do not have stronger preferences for children’s meals than men. Finally, we document a significant heterogeneity in both individual preferences and intra-household decision-making processes.
