The Revealed Preference Approach to Collective Consumption Behaviour: Testing and Sharing Rule Recovery
提出一种整数规划方法，检验集体消费数据是否与包含公共品和私人品的消费模型一致，并恢复私人品的个性化价格和数量，进而恢复家庭内收入分享规则。
We present a revealed preference methodology for empirically analysing collective consumption behaviour. First, we introduce an integer programming (IP) methodology for testing data consistency with collective consumption models that account for publicly as well as privately consumed goods. This IP methodology can include information on “assignable quantities” for private goods. Next, we show that the IP methodology allows for recovering the personalized (Lindahl) prices for the public goods and the personalized quantities for the private goods. In turn, this implies recovery of the sharing rule (i.e. personalized income share levels). An empirical application demonstrates the practical usefulness of the methodology.
