This paper investigates how perceived costs and benefits of control among Danish pig farmers affect the farmers' choice of action toward reducing the prevalence of in their herds. Based on data from an online questionnaire involving 163 Danish pig farmers, we find a considerable uncertainty among pig farmers about the perceived effects of the reducing actions. The results indicate large variations in the perceived costs of implementing different types of reducing actions (management-, hygiene- and feed-related). For some cases, farmers associate net benefits and positive productivity effects with implementation of the actions while studies by the industry indicate net costs to the farmers. Differences among farmers support the idea of an outcome-based penalty scheme but the large uncertainties about costs and effects of actions toward control might hamper the effectiveness of such a penalty scheme as a regulatory instrument to affect farmer behavior.
本文研究了丹麦养猪户对控制措施的感知成本和收益如何影响他们为降低猪群患病率而采取行动的选择。基于一项涉及163名丹麦养猪户的在线调查问卷数据，我们发现养猪户对降低患病率行动的感知效果存在相当大的不确定性。结果表明，实施不同类型的降低患病率行动（管理、卫生和饲料相关）的感知成本存在很大差异。在某些情况下，农民将净收益和积极的生产力影响与行动的实施联系起来，而行业研究表明对农民来说是净成本。农民之间的差异支持基于结果的处罚计划的想法，但控制患病率行动的成本和效果的巨大不确定性可能会阻碍这种处罚计划作为影响农民行为的监管工具的有效性。
