相互联系的一般均衡经济模型和生态模型通过农业径流和渔业联系在一起。它们被应用于北卡罗来纳州的一个河口，那里的农业径流改变了浮游植物的密度，由此导致的缺氧导致渔业减少。分析了低氧对空间上多种物种的影响，并量化了减少径流政策对经济和整个生态系统的联合反应。该方法提供了对径流减少后生态福利(就物种数量而言)和经济福利(根据等效变化)的变化的评估。
Linked general equilibrium economic and ecological models are connected through agricultural runoff and the fisheries. They are applied to a North Carolina estuary in which agricultural runoff alters phytoplankton densities and the resulting hypoxia leads to diminished fisheries. The effects of hypoxia on multiple species across space are analyzed and the joint economic and ecosystem wide response to a policy of reduced runoff is quantified. The approach provides an assessment of changes in ecological welfare (in terms of species populations) and economic welfare (in terms of equivalent variations) following reductions in runoff.
