Decreasing Impatience
研究了跨期选择中常见的递减不耐烦现象，通过固定利率投资的凸性公理刻画了具有递减不耐烦的贴现因子，并证明其等价于广义拟双曲贴现率的几何平均，以及指数贴现因子的对赌偏好聚合结果。
We characterize decreasing impatience, a common behavioral phenomenon in intertemporal choice. Discount factors that display decreasing impatience are characterized through a convexity axiom for investments at fixed interest rates. Then we show that they are equivalent to a geometric average of generalized quasi-hyperbolic discount rates. Finally, they emerge through parimutuel preference aggregation of exponential discount factors.
