Common Ground Between Free‐Traders and Environmentalists
用一个南北模型研究贸易对资源使用和福利的影响，发现环境脆弱时自给自足可能优于自由贸易，环境有韧性时则相反，并分析了穷国拖累富国或富国带动穷国的机制。
We use a North–South model with property right differences and resource dynamics to study the effects of trade on resource use and welfare. Autarky is likely to Pareto‐dominate free trade in the long run when the environment is quite fragile, and the result is reversed when the environment is quite resilient. Trade may cause an environmentally poor country to “drag down” its richer trading partner, when they degrade their stocks which would be preserved under autarky. It may enable the environmentally richer country to “pull up” its partner, when they preserve their stocks which would be degraded under autarky.
