Chasing the Spillovers: Locating Protected Areas in a Trans-Boundary Fishery
研究了在跨界渔业中，国家合作与否对海洋保护区选址的影响，发现不合作可能导致囚徒困境，使国家选择的保护区偏离社会或生态最优。
<i>Marine protected areas (MPAs) can positively impact upon marine biodiversity and fisheries returns. Increased fish densities inside MPAs can positively affect catches outside these areas. We examine MPA placement in a transboundary fishery when nations are, and are not, cooperative. We apply a differential game using a bioeconomic model to analyze behavior in MPA placement and effects on effort and biomass in two nations if both nations implement an MPA. Absence of cooperation can result in a prisoners’ dilemma in MPA placement. Strategic interactions lead to a divergence between socially or ecologically optimal MPAs and those chosen by national governments.</i>
