我们开发了一个新版本的前景理论，采用累积而不是可分离的决策权重，并在几个方面扩展了理论。这个版本，称为累积前景理论，适用于不确定的以及风险的前景与任何数量的结果，它允许不同的加权函数的收益和损失。两个原则，灵敏度递减和损失厌恶，被援引来解释的特征曲率的价值函数和权重函数。一个新的实验的实验证据和结果的审查证实了一个独特的四重模式的风险态度：风险规避收益和风险寻求损失的高概率;风险寻求收益和风险规避损失的低概率。
We develop a new version of prospect theory that employs cumulative rather than separable decision weights and extends the theory in several respects. This version, called cumulative prospect theory, applies to uncertain as well as to risky prospects with any number of outcomes, and it allows different weighting functions for gains and for losses. Two principles, diminishing sensitivity and loss aversion, are invoked to explain the characteristic curvature of the value function and the weighting functions. A review of the experimental evidence and the results of a new experiment confirm a distinctive fourfold pattern of risk attitudes: risk aversion for gains and risk seeking for losses of high probability; risk seeking for gains and risk aversion for losses of low probability.
