我们在传统的非洲食品市场上激发人们购买传统、有机和/或经过食品安全检验的西红柿的意愿。我们确定了四种可以一次对一名受访者进行的启发方法，并在现场环境中使用它们：Becker-DeGroot-Marschak 机制、多个价目表、指定数量的多个价目表以及真实选择实验。所有四种方法都给出相似的结果；这表明消费者愿意为有机且经过食品安全检验的西红柿支付高价。然而，当消费者在不同选择之间进行选择时，溢价的数额明显大于他们表明保留价格时的溢价。新的标有数量的多重价目表在繁忙的市场环境中很容易解释，让受访者有机会确定他们想要购买的数量，并且估值与其他非比较估值方法一致。
We elicit willingness to pay for conventional, organic and/or food-safety-inspected tomatoes in a traditional African food market. We identify four elicitation methods that can be conducted with one respondent at a time, and use them in a field setting: the Becker-DeGroot-Marschak mechanism, multiple price lists, multiple price lists with stated quantities, and real-choice experiments. All four methods give similar results; showing that consumers are willing to pay a premium for organic and food-safety-inspected tomatoes. However, the size of the premium is significantly larger when consumers choose between alternatives than when they indicate their reservation price. The new multiple price lists with stated quantities were easy to explain in the busy market setting, gave the respondents the opportunity to determine the amount they wanted to buy, and had valuations in line with the other non-comparative valuation methods.
