Module 7-书(2022-L1V2)P363-6.1 Tariffs 标题下方第一段的最后一句话,怎么理解?the large country cannot gain by imposing a tariff unless it imposes an even larger loss on its trading partner. 这里说的是cannot gain by imposing a tariff, 但是前面又说it is possible for a large country to increase its welfare? 这不是前后矛盾了吗?

你好同学
有关关税的计算(下页图表中)都是关于小国的。可以看出,有了关税后National welfare是下降的。
但是对于大国来说,大国加关税以后,小国为了保持住市场份额,会降价。加了关税,物价没有上涨,大国国民没有deadweight loss,反而收获了一笔关税。
你标黄的最后一句意思是说。如果小国偏不降价,没有出现“larger loss on its trading partner"的情况,那么大国也是会出现National welfare下降的情况的。

怎么理解截图中的这句话:So, in theory it is possible for a large country to increase its welfare by imposing a tariff if 2) the deadweight loss as a result of the tariff (see below) is smaller than the benefit of improving its terms of trade. 不明白,为什么关税造成的无谓损失小于改善其贸易条件的好处,一个大国就有可能通过征收关税来增加其福利?书上第几页有这个知识点?

就是前半段话里When a large country imposes a tariff, the exporter reduces the price of the
good to retain some of the market share it could lose if it did not lower its price. This
reduction in price alters the terms of trade and represents a redistribution of income
from the exporting country to the importing country
大国是产品主要消费国,那么大国增加关税势必导致大国国内该商品价格增高,小国为了保证市场份额,维持利润,会降低价格。那么大国会多收取一部分关税。表二里,national welfare部分是-(b+d).假设大国多收取的关税是e.那么大国最终的福利e-(b+d),要看e跟b+d的大小。e比b+d大的话,大国总福利是增加的。
