The Spatial Dynamics of the Economic Impacts of an Aquatic Invasive Species: An Empirical Analysis
研究了淡水湖泊水生植物入侵的经济损失如何在被入侵湖泊用户和邻近湖泊用户之间分配，发现早期跨湖泊协调管理价值最高。
This paper examines how the economic loss from an aquatic species invasion of a freshwater lake is allocated between users of the lake itself (own-lake effect) and users of neighboring lakes that become invaded because the lake is a new source of the invader (spillover effect). The empirical application concerns the Eurasian watermilfoil invasion in the lake-rich landscape of northern Wisconsin. Results suggest that coordinated management across lakes provides its highest economic value in the early years of an invasion, before high-value, high-traffic lakes are invaded, and drops quickly once the invasion claims these lakes. <i></i>
