Revealed Preference Analysis of Non‐Cooperative Household Consumption
提出一种显示偏好方法，分析非合作（非帕累托有效）的家庭消费行为，推导出数据与模型一致性的全局充要条件，并通过俄罗斯追踪调查数据验证了非合作消费模型的实证相关性。
We develop a revealed preference approach to analyze non-unitary household consumption behavior that is not cooperative (or Pareto e ¢ cient). We derive global and necessary and su ¢ cient conditions for data consistency with the model. Interestingly, contrary to existing results for the di¤erential approach, these revealed preference conditions for the noncooperative model are independent from (or non-nested with) the conditions for the cooperative model. We show that the conditions can be veri…ed by means of relatively straightforward mixed integer programming (MIP) methods, which is particularly attractive in view of empirical analysis. Our framework extends to tests for separate spheres and joint contribution to public goods. An application to data drawn from the Russia Longitudinal Monitoring Survey (RLMS) demonstrates the empirical relevance of the noncooperative consumption model. To the best of our knowledge, this is the …rst empirical application of the noncooperative consumption model. JEL Classi…cation: D11, D12, D13, C14.
