本文认为,在具有单一消费商品的经济体中,跨期金融市场的不完全性对福利、价格或消费几乎没有影响,前提是交易者寿命长、耐心,交易的是无风险债券,冲击是暂时的,不存在总风险。在一个具有总风险的经济体中,只要交易者共享相同的CRRA效用函数,并交易正确的资产,类似的结论就成立了。例子表明,如果交易了错误的资产,或者经济体拥有多种消费品,这些结论就不一定成立。
This paper argues that incompleteness of intertemporal financial markets has little effect (on welfare, prices, or consumption) in an economy with a single consumption good, provided that traders are long-lived and patient, a riskless bond is traded, shocks are transitory, and there is no aggregate risk. In an economy with aggregate risk, a similar conclusion holds, provided traders share the same CRRA utility function and the right assets are traded. Examples demonstrate that these conclusions need not hold if the wrong assets are traded or if the economy has multiple consumption goods.
