Efficient Responses to Targeted Cash Transfers
利用墨西哥农村大型条件现金转移项目的数据，检验家庭消费集体模型的约束条件，发现该模型能解释项目对食品消费结构的影响，且比单一模型更能预测外生收入增加的效果。
We estimate and test the restrictions of a collective model of household consumption, using z-conditional demands, in the context of a large conditional cash transfer program in rural Mexico. The model can explain the impacts of the program on the structure of food consumption. We use two plausible and novel distribution factors: the random allocation of a cash transfer to women and the relative size and wealth of the husband's and wife's family networks. Our structure does better at predicting the effect of exogenous increases in household income than an alternative, unitary, structure. We cannot reject efficiency of household decisions.
