Multivariate Risk Aversion and Consumer Choice
分析风险厌恶程度增加对多风险来源的消费者选择模型的影响，推导出需求函数随风险厌恶增加而变化的充分条件，并用两期消费储蓄模型说明。
This paper analyzes the effect of increases in risk aversion on a general consumer choice model with multiple sources of risk. Sufficient--and, in the two commodity case, necessary--conditions for a given demand function to increase (or decrease) with increased risk aversion are derived. These general results are illustrated with a two-period, consumption-savings model.
