The Implications of Additive Community Preferences in a Multi-Consume Economy
研究在社区偏好上施加加总性的后果，发现这会导致存在一个具有CES效用函数的代表性消费者，并通过三个例子说明其限制性，表明单消费者模型无法充分代表多消费者经济的重要特征。
We investigate the consequences of imposing additivity on community preferences. We show that there are important implications of additive community preferences that are not implied by the additivity of a single consumer's preferences. In particular, we show that imposing additivity on community preferences implies the existence of a representative consumer with a utility function in the CES family. We demonstrate the restrictive nature of these implications with three examples. Our interpretation of the results is that single consumer models are unable to adequately represent important features of multi-consumer economies.
