The Environmental Consequences of Global Reuse
研究了一个两国模型，求解在旧消费电子产品国际贸易中实现效率的最优税率，发现发达国家可通过征收进口关税或补贴电子废物回收达到全球帕累托最优。
This paper summarizes a two-country model that solves for optimal tax rates to achieve efficiency in an economy with international trade in used consumer electronics. If only the developed nation can tax the disposal of e-waste, then the global Pareto Optimum can be obtained by either imposing an import tariff on used consumer electronics or subsidizing the return of e-waste for disposal in the developed country. The global Pareto Optimum can also be obtained by reducing the disposal tax in the developed country to a level below the external marginal cost of disposal should no other policy option be available.
