Rince Preferences
提出一类名为RINCE的偏好，基于Kreps-Porteus公理，能分离风险态度与跨期替代弹性，并给出动态随机选择问题的闭式解。
This paper presents a class of preferences that yield closed-form solutions to dynamic stochastic choice problems. These preferences are based on a set of axioms that were proposed by Kreps and Porteus. The Kreps-Porteus axioms allow one to separate an agent's attitudes to risk from his or her intertemporal elasticity of substitution. RINCE preferences have the properties of Risk Neutrality and Constant Elasticity of substitution.
