Can intertemporal choice experiments elicit time preferences for consumption?
研究了当被试能在外部资本市场调整消费时，实验室中货币跨期选择任务能否真正测度其消费时间偏好，并评析了文献中的三种观点。
Abstract The paper considers what can be inferred about experimental subjects’ time preferences for consumption from responses to laboratory tasks involving tradeoffs between sums of money at different dates, if subjects can reschedule consumption spending relative to income in external capital markets. It distinguishes three approaches identifiable in the literature: the straightforward view; the separation view; and the censored data view. It shows that none of these is fully satisfactory and discusses the resulting implications for intertemporal decision-making experiments.
