In the animal health arena, government-mandated testing, herd movement restrictions, and culling of reactor (infected) animals are common practices in the midst of an infectious disease outbreak. These policies create a significant economic trade-off—on one hand, such control efforts represent a public good by reducing the negative externality of private actions associated with the transmission of infectious disease; on the other hand, they impose substantial economic costs on the affected farms. This paper empirically evaluates the economic trade-offs created by disease control efforts in the context of bovine tuberculosis (bTB) in Great Britain. We find that—in this context—government control efforts are clearly cost-effective. Mandatory testing, imposition of movement restrictions on infected herds, and culling of reactor animals generate an annual external value of approximately £152 million to the British beef sector with a social return-on-investment of 3.46. Moreover, coupled compensation averts approximately 75% of the farm exits that would otherwise have resulted from these policies.

英国牛结核病控制计划的投资回报

在动物健康领域,政府强制进行的检测、畜群迁移限制和对反应堆(感染)动物的扑杀是传染病爆发期间的常见做法。这些政策产生了重大的经济权衡——一方面,这种控制努力通过减少与传染病传播相关的私人行动的负面外部性,代表了一种公共产品;另一方面,它们给受影响的农场带来了巨大的经济成本。本文实证评估了英国在牛结核病 (bTB) 的背景下疾病控制工作所产生的经济权衡。我们发现——在这种情况下——政府的控制努力显然具有成本效益。强制检测,对受感染的畜群实施行动限制,和淘汰反应堆动物每年为英国牛肉行业带来约 1.52 亿英镑的外部价值,社会投资回报率为 3.46。此外,联合补偿避免了大约 75% 的农场退出,否则这些政策会导致这些退出。
