Out of the Wallet and into the Purse: Using Micro Data to Test Income Pooling
利用英国家庭津贴政策变化造成家庭内部收入分配的外生变动，检验了单一家庭模型中的收入汇集假说。基于家庭层面数据估计多种商品的支出份额，发现政策将收入从男性转向女性和儿童后，支出份额发生相应变化，而有无孩子的家庭反应不同，从而否定了收入汇集假说。
This paper uses an exogenous change in the intrahousehold distribution of income, provided by a change in United Kingdom Family Allowance policy to test the income-pooling hypothesis implied by unitary household models. Expenditure shares are estimated for a wide range of goods using household-level data. Shifts in expenditure shares suggest that children and mothers benefited at the expense of fathers when this policy change shifted income within households from men to women. Similar shifts are not found among married-couple households with no children. This paper refutes income pooling, and confirms and extends results in Lundberg, Pollak, and Wales (1997).
