An Empirical Test of Gain-Loss Separability in Prospect Theory
通过两个实验检验前景理论中得失可分离性的基本前提，发现混合赌博的偏好与得失部分偏好之间存在反转，表明个体在混合赌博中对概率差异的敏感度较低。
We investigate a basic premise of prospect theory: that the valuation of gains and losses is separable. In prospect theory, gain-loss separability implies that a mixed gamble is valued by summing the valuations of the gain and loss portions of that gamble. Two experimental studies demonstrate a systematic violation of the double-matching axiom, an axiom that is necessary for gain-loss separability. We document a reversal between preferences for mixed gambles and the associated gain and loss gambles—mixed gamble A is preferred to mixed gamble B, but the gain and loss portions of B are preferred to the gain and loss portions of A. The observed choice patterns are consistent with a process in which individuals are less sensitive to probability differences when choosing among mixed gambles than when choosing among either gain or loss gambles.
