Valuing Food Safety in Experimental Auction Markets
通过实验拍卖市场，在非假设情境下评估食品安全的价值，发现被试低估低概率食源性疾病风险，且支付意愿在广泛风险范围内变化平缓，边际支付意愿随风险增加而下降。
Abstract In this paper, we value food safety in a nonhypothetical setting—experimental auction markets. First, subjects underestimate the relatively low probabilities of food‐borne illness. Second, measures of value are within a relatively flat range across a wide range of risks, even with repeated market experience and full information on the objective probability and severity of illness, suggesting subjects rely on prior perceptions. Third, marginal willingness to pay decreases as risk increases, suggesting that the perceived quality of new information can affect the weight the individuals place on the information. Finally, pathogen‐specific values seem to act as surrogates for general food safety preferences.
