Strotz Meets Allais: Diminishing Impatience and the Certainty Effect: Comment
指出Halevy（2008）关于递减不耐（准双曲贴现）与共同比率效应等价的论断有误，并修正了正确关系：递减不耐等价于确定性效应，而强递减不耐（双曲贴现）等价于共同比率效应。
Halevy (2008) states the equivalence between diminishing impatience (i.e., quasi–hyperbolic discounting) and the common ratio effect. The present paper shows that one way of the equivalence is false and shows the correct and general relationships: diminishing impatience is equivalent to the certainty effect and that strong diminishing impatience (i.e., hyperbolic discounting) is equivalent to the common ratio effect.
