A Test of the Unitary and Collective Models of Household Labour Supply
在结构框架下检验了家庭劳动供给的统一模型和集体模型，发现统一模型的收入汇集限制和交叉工资效应对称性被拒绝，但集体模型在无学龄前儿童群体中未被拒绝。
This paper tests the unitary and the collective household labour supply models within a structural framework. A nonlinear unrestricted household labour supply system is postulated and the set of parametric restrictions imposed by each model is derived. Our results generally reject the income pooling restrictions embodied in the unitary model. Also, the symmetry of cross‐wage effects is rejected. However, the collective model is not rejected for groups with no pre‐school children.
