模糊产品信息的益处与挑战
Benefits and challenges of ambiguous product information
摘要
We study the welfare effects of ambiguous product information for a buyer with α ‐max‐min preferences and a price‐setting seller. The buyer privately receives information about her valuation. We show that both the seller and the buyer can benefit when this information is ambiguous, and we characterize all possible combinations of producer and consumer surplus, as evaluated under ambiguity‐sensitive preferences. Ambiguity concerning the valuation perceived by the buyer when making the purchase decision can induce the seller to change the price. Before receiving information, ambiguity concerning the purchase decision can make the buyer optimistic about buying only for high valuations, which relaxes the participation constraint.
中文摘要
我们研究了模糊产品信息对具有α-最大最小偏好的买方与定价卖方产生的福利效应。买方私下获取关于自身估值的信息。研究表明，当该信息存在模糊性时，买卖双方均可能获益，并刻画了在模糊敏感偏好评估下生产者剩余与消费者剩余的所有可能组合。买方在做出购买决策时所感知的估值模糊性，会促使卖方调整价格。在获取信息前，购买决策的模糊性可能使买方对仅在高估值时购买持乐观态度，从而放宽了参与约束条件。
