Does a larger country set a higher optimal tariff with monopolistic competition and capital accumulation?
在一个包含垄断竞争和资本积累的两国内生增长模型中，研究发现一国的关税最优水平为正，但生产率更高、经济规模更大的国家设定的最优关税反而更低。
In a two-country endogenous growth model with monopolistic competition and capital accumulation, we show that: (i) a country’s optimal tariff is positive; and (ii) a more productive, and hence an economically larger, country sets a lower optimal tariff.
