The aim of this note is to estimate the discount rates that individuals in the present generation in Sweden use to discount lives saved in future generations at different points in time. A binary survey question, where individuals choose between saving lives in their own generation versus saving lives in future generations, was administered in a general population sample of 850 individuals. Three time horizons of 20, 50 and 100 years were used in three different subsamples. Logistic regression analysis was used to estimate the discount rate. The estimated annual discount rate is 25% for the 20 year time horizon, 12% for the 50 year time horizon and 8% for the 100 year time horizon.
本报告的目的是估计瑞典当代人在不同时间点用于贴现后代所拯救生命的贴现率。向850人的普通人群样本提出了一个二元调查问题，让个体在拯救本代人的生命和拯救后代人的生命之间做出选择。在三个不同的子样本中使用了20年、50年和100年这三个时间跨度。采用逻辑回归分析来估计贴现率。对于20年的时间跨度，估计的年贴现率为25%；对于50年的时间跨度，为12%；对于100年的时间跨度，为8%。
