Magnitude effect in intertemporal allocation tasks
通过跨期分配任务，研究了总预算大小如何影响折现率和效用曲率，发现大预算下人们更耐心且认为预算更可替代。
Abstract Intertemporal choices are affected by both discount rate and utility curvature. We investigate how the two aspects of time preference are affected by the size of the total budget using an intertemporal allocation task. At the aggregate level as well as at the individual level, we find magnitude effects both on the discount rate and on intertemporal substitutability (i.e., utility curvature). Individuals are more patient when dealing with larger budgets and also regard larger budgets to be more fungible. The latter effect suggests that the degree of asset integration is increasing in the stake.
