Efficient Intra-Household Allocations and Distribution Factors: Implications and Identification
系统刻画了在价格不变情况下集体框架的可检验性和可识别性问题，为近期实证研究提供理论基础，提出帕累托效率假设的检验方法，并给出共享规则和个人恩格尔曲线的识别条件。
This paper provides an exhaustive characterization of testability and identifiability issues in the collective framework in the absence of price variation; it thus provides a theoretical underpinning for a number of empirical works that have been developed recently. We first provide a simple and general test of the Pareto-efficiency hypothesis, which is consistent with all possible assumptions on the private or public nature of goods, all possible consumption externalities between household members, and all types of interdependent individual preferences and domestic production technology. The test is proved to be necessary and sufficient. We then provide conditions for the identification of the sharing rule and the Engel curves of individual household members for a variety of different observational schemes.
