Is the Allocation of Resources within the Household Efficient? New Evidence from a Randomized Experiment
利用墨西哥PROGRESA项目带来的女性收入随机变化和局部降雨冲击作为分配因素，检验家庭内部资源配置是否满足帕累托最优，发现女性收入增加会更多用于儿童商品支出，而降雨冲击对家庭公共品支出影响较小，支持帕累托效率假说。
I study whether households make Pareto-efficient intrahousehold resource allocation decisions. Combining randomized variation in women's income generated by the evaluation of the Mexican PROGRESA program with variation attributable to localized rainfall shocks as distribution factors in the collective model, I find evidence favoring Pareto optimality. More specifically, female-specific income changes have positive effects on children's goods expenditures, whereas changes due to rainfall shocks have a smaller influence on household public goods expenditures. The evidence is consistent with female partners having greater sensitivity to own-income changes and norms that oblige women to devote their earnings to meet collective consumption needs.
