Previous research shows that sinkhole presence, proximity, and density create negative externalities and all have a significant negative effect on house prices. This study extends sinkhole research by examining opportunistic fraud and moral hazard associated with the relationship between sinkhole insurance claims and house prices. This is done by evaluating the relationship between house prices and the payment or denial of sinkhole insurance claims for both affected properties and neighboring properties. Applying a spatial error regression model to single-family detached home sales and sinkhole insurance claims data for Hillsborough County, Florida for the period 2008 to 2016, we find that not only do sinkhole insurance claims have a negative impact on the property associated with the claim, but also have a negative impact on surrounding properties regardless of the source of classification. This result holds for both paid and unpaid insurance claims. The results also show a price discount even after the sinkhole has been remediated.

先前的研究表明，污水坑的存在，邻近性和密度都会产生负面的外部影响，并且都对房价产生重大的负面影响。这项研究通过检查与欺诈性保险索赔和房价之间的关系相关的机会主义欺诈和道德风险，扩展了漏洞的研究。这是通过评估房价和受影响财产及邻近财产的付款或拒绝污水坑保险索偿之间的关系来完成的。将空间误差回归模型应用于佛罗里达州希尔斯伯勒县2008年至2016年的单户独立式房屋销售和污水坑保险理赔数据，我们发现污水坑保险理赔不仅会对与索赔相关的财产产生负面影响，但无论分类的来源如何，都会对周围的特性产生负面影响。该结果适用于已付费和未付费的保险索赔。结果也显示出价格折扣，即使已经解决了水坑。
