Willingness to pay for reductions in health risks when probabilities are distorted
研究了当人们非线性评估概率（即概率加权）时，降低健康风险的支付意愿如何变化，发现概率加权会显著影响支付意愿估计，并可能导致健康货币估值不稳定。
We study the willingness to pay for reductions in health risks when people do not evaluate probabilities linearly, as is commonly assumed in elicitations of willingness to pay, but weight probabilities, as is commonly observed in empirical studies of decision under risk. We show that for the levels of baseline risk typically considered, probability weighting strongly affects willingness to pay estimates and may lead to unstable monetary valuations of health.
