Out of the Wallet and into the Purse
利用英国家庭津贴政策的外生变化，检验家庭内部收入是否被统一支配。结果显示，当收入从丈夫转向妻子时，儿童和母亲的消费份额增加，而父亲减少，否定了收入统一支配假说。
Abstract 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).
