Lost Use-Value from Environmental Injury When Visitation Drops at Undamaged Sites
研究了环境损害导致未受损地点访问量下降时的福利损失计算方法，发现标准公式会低估或高估损失，并提供了修正公式，应用于深水地平线漏油事件的海岸线使用损失估算。
We describe welfare calculations when an environmental injury reduces trips to undamaged sites as well as those that were damaged. The welfare loss is (1) underestimated when standard welfare formulas are applied only to damaged sites but (2) overestimated when these formulas are applied to all sites with lost trips. We provide a formula that appropriately accounts for the lost trips to undamaged sites. Differences among the procedures are illustrated through hypothetical scenarios that differ in lost trips to undamaged sites. We apply the method under linear demand to aggregate estimates of shoreline-use losses from the Deepwater Horizon oil spill. <i></i>
