Should We Tax Trade? A Pigouvian Perspective
我们应该对贸易征税吗？一个庇古视角
贸易·开放贸易政策
我们构建了一个简洁直观的庇古视角来分析最优贸易政策。我们的方法统一了主张对贸易征税的多种理由，从经典的最优关税论到当代关于全球碳排放与地缘政治的争论。我们还厘清了贸易政策干预何时是合理的，以及何时应当转而采用替代性的国内政策工具。
英文原文
We develop a simple and intuitive Pigouvian perspective on optimal trade policy. Our approach unifies a wide range of rationales for taxing trade, from the classical optimal tariff argument to contemporary debates about global carbon emissions and geopolitics. We also clarify when trade policy intervention is warranted and when alternative domestic instruments should be used instead.
