Discounting health and money: New evidence using a more robust method
通过实地调查，使用直接法测量法国代表性样本对金钱和健康的贴现率，发现金钱贴现率高于健康，且贴现率接近市场利率，解决了以往研究中贴现率过高的问题。
This study compares discounting for money and health in a field study. We applied the direct method, which measures discounting independent of utility, in a representative French sample, interviewed at home by professional interviewers. We found more discounting for money than for health. The median discount rates (6.5% for money and 2.2% for health) were close to market interest rates, suggesting that at the aggregate level the direct method solves the puzzle of unrealistically high discount rates typically observed in applied economics. Constant discounting fitted the data better than the hyperbolic discounting models that we considered. The substantial individual heterogeneity in discounting was correlated with age and occupation.
