Household Decisions and Equilibrium Efficiency
建立了一个包含多成员家庭的一般均衡模型，分析家庭内部外部性如何被内部化，以及竞争性交换在家庭间和个体间的效率差异。
A general equilibrium model is introduced where a household may consist of several members, each with individual preferences and/or resources. When households obey collective rationality, certain intrahousehold externalities can be fully internalized by the respective households so that competitive exchange among households is efficient. As a rule, however, such intrahousehold externalities are not fully internalized by individual household members acting in their personal interest so that competitive exchange among such individuals is only efficient in exceptional cases.
