Integrability of Incomplete Systems of Demand Functions
研究如何从不完整的需求函数集合反推出效用函数，分析了局部和全局可积性的条件，对研究需求理论和消费者行为的学者有参考价值。
The problem of integrating back from an incomplete set of demand functions to a utility function is considered. Conditions permitting local integrability are analogous to those which arise in local integrability theorems for complete systems. But the analysis of the global integrability of incomplete systems differs markedly from that of complete systems.
