Livestock industries are vulnerable to disease threats, which can cost billions of dollars and have substantial negative social ramifications. Losses are mitigated through increased use of disease-related biosecurity practices, making increased biosecurity an industry goal. Currently, there is no industry-wide standard for sharing information about disease incidence or on-site biosecurity strategies, resulting in uncertainty regarding disease prevalence and biosecurity strategies employed by industry stakeholders. Using an experimental simulation game, with primarily student participants, we examined willingness to invest in biosecurity when confronted with disease outbreak scenarios. We varied the scenarios by changing the information provided about 1) disease incidence and 2) biosecurity strategy or response by production facilities to the threat of disease. Here we show that willingness to invest in biosecurity increases with increased information about disease incidence, but decreases with increased information about biosecurity practices used by nearby facilities. Thus, the type or context of the uncertainty confronting the decision maker may be a major factor influencing behavior. Our findings suggest that policies and practices that encourage greater sharing of disease incidence information should have the greatest benefit for protecting herd health.
畜牧业容易受到疾病威胁,这可能造成数十亿美元的损失,并产生重大的负面社会影响。通过增加使用与疾病相关的生物安全措施,可以减轻损失,因此提高生物安全性是行业的目标。目前,畜牧业没有关于疾病发病率或现场生物安全策略的信息共享的行业标准,导致对疾病流行情况和行业利益相关者采用的生物安全策略存在不确定性。我们使用了一个实验模拟游戏,主要参与者是学生,研究了在面临疾病爆发情景时对生物安全的投资意愿。我们通过改变情景来改变信息,这些信息涉及到 1)疾病发病率和 2)生物安全策略或生产设施对疾病威胁的反应。我们发现,当提供更多关于疾病发病率的信息时,对生物安全的投资意愿会增加,但当提供更多关于附近设施使用的生物安全措施的信息时,投资意愿会降低。因此,决策者面临的不确定性的类型或背景可能是影响行为的一个主要因素。我们的研究结果表明,鼓励增加疾病发病率信息共享的政策和做法,对保护畜群健康应该具有最大的益处。
