Consumer Demand for a Ban on Antibiotic Drug Use in Pork Production
通过超市实验，估计消费者对无抗生素猪肉的支付意愿及对抗生素耐药性减少的贡献意愿，发现禁令的福利效应取决于消费者对猪肉生产中抗生素使用的了解程度和购买无抗生素猪肉的便利性。
Both bodies of the U.S. Congress have recently considered legislation to restrict use of antibiotics in livestock feed. Although several studies have addressed the costs of such restrictions, little is known about consumer demand. This study estimates consumers' willingness to pay for pork produced without subtherapeutic antibiotics and consumers' willingness to contribute to a reduction in antibiotic resistance by collecting data in a grocery store environment with mechanisms that involve the exchange of real food and real money. Results indicate that the welfare effects of a ban depend heavily on assumptions about consumers' current knowledge about antibiotic use in pork production and the extent to which consumers are currently able to purchase antibiotic‐free pork.
