Do Big Countries Win Tariff Wars?
用一个简单的两国两商品纯交换模型，分析不同资源禀赋下关税战的结果，发现如果一国规模远大于另一国，即使对方报复，大国仍可能从关税战中获益。
Yes. It is widely believed that tariffs invite retaliation, and that the postretaliation equilibrium l eaves all countries worse off than they would be at free trade. The a uthors present a simple pure exchange model, with two countries and t wo goods, and show which endowment patterns are consistent with this belief. They find that if one country is substantially bigger than th e other it can expect to gain from a tariff war, despite retaliation. The model can be extended to show that the advantage obtained by bei ng part of a large trading unit can help explain the formation of cus toms unions.
