Group Consumption with Caring Individuals
提出一个模型来刻画相互关怀的个体如何共同做出消费决策，该模型涵盖从完全合作到完全不合作的连续谱系，并定义了一个衡量群体内合作程度的指标，通过显示偏好方法推导出可检验的实证含义，并用儿童实验数据进行分析。
Abstract We propose a novel approach to model joint consumption decisions of individuals who care for each other. The model encompasses a continuum of group consumption models situated between the fully co-operative model and the non-cooperative model without caring. We also define a measure for the degree of intragroup cooperation that quantifies how close the observed group behaviour is to fully co-operative behaviour. Following a revealed preference approach, we derive testable implications of the model for empirical data. We use our model to analyse decisions made by children in an experimental setting.
