摘要

我量化了比较优势和污染港效应（PHE）是如何影响国际废物流动的，并通过构建一个将废物的产生、贸易和使用作为生产投入的李嘉图模型来推断相关的外部性成本。将废物流、关税和环境监管数据与气象污染分散仪器相结合，我估计贸易成本每增加1%，各种废物流就会减少7%-29.3%。相对于目的地而言，原产地更严格的环境法规使某些废物的贸易成本降低了7%-77.7%。单位外部性成本增加，但废物贸易的收益随着收入的增加而减少，其中公共卫生部门的贡献很大。

Global waste trade: Comparative advantage, the pollution haven effect, and externality costs

I quantify how comparative advantage and the pollution haven effect (PHE) shape international waste flows and infer the associated externality costs by constructing a Ricardian model with generation, trade, and use as a production input of waste. Combining waste flow, tariff, and environmental regulation data with a meteorological pollution dispersion instrument, I estimate that a 1% increase in trade costs reduces various waste flows by 7%–29.3%. Stricter environmental regulation in origin relative to the destination lowers trade costs for certain waste by 7%–77.7%. Per-unit externality costs increase but gains from waste trade decrease with income, with PHE contributing substantially.
