我们估算了马萨诸塞州桑威奇海岸线变化带来的风险的经济成本，桑威奇是一个历史悠久的小镇，位于上科德角，海岸线长约八英里。我们研究了两类自变量与评估财产价值的关系：（1）描述建筑物物理质量的结构特征，以及（2）衡量海岸线变化对沿海财产造成的风险的环境特征。我们发现七个环境变量中有六个有助于解释评估值的变化，包括侵蚀风险的衡量标准。结果与之前发布的美国东海岸其他地点的结果进行了比较。我们估计，桑威奇每年因海岸线改变而产生的成本约为 1-200 万美元，但土地和建筑物的实际损失仅占这些成本的 3% 左右。讨论了我们的结果在选择缓解措施中的应用。
We estimate the economic costs of the risks posed by shoreline change in Sandwich, Massachusetts, an historic town with approximately eight miles of shoreline located on Upper Cape Cod. We examine the relationship to assessed property values of two types of independent variables: (1) structural characteristics describing the physical qualities of a building, and (2) environmental characteristics measuring the risk posed to coastal properties by shoreline change. We find that six of seven environmental variables help to explain variations in assessed value, including a measure of erosion risk. Results are compared to previously published results from other US east coast locations. We estimate that the annual costs of shoreline change in Sandwich are on the order of $1-2 million, but the physical losses of land and structures account for only about three percent of those costs. The application of our results to the selection of mitigation measures is discussed.
