QuestionIn the context of a price taker nation levying a tariff on an imported item:
选项：
A.the overall welfare of the nation improves.
there's an uptick in consumer surplus.
C.local producers experience a surge in producer surplus.
解释：
Solution
- Incorrect, as imposing a tariff in a country that is a price taker will not result in an overall increase in national welfare. While some entities might benefit, the aggregate effect is typically a deadweight loss.
- Incorrect, since levying a tariff usually results in increased prices for imported goods, causing a reduction in consumer surplus.
- Correct. Domestic producers will indeed benefit from the tariff as it offers protection against cheaper imports, leading to an increase in their producer surplus. However, this gain is often offset by the losses faced by consumers.
•
A不正确，因为在一个价格接受者的国家征收关税不会导致国家福利的总体增加。虽然某些实体可能会受益，但总体效果通常是无谓损失。
B不正确，因为征收关税通常会导致进口商品价格上涨，导致消费者剩余减少。
C正确。国内生产商确实会从关税中受益，因为它提供了对廉价进口产品的保护，导致它们的生产商盈余增加。然而，这种收益往往被消费者面临的损失所抵消。
b 价格增加为什么消费者剩余会增加？
价格增加不是越少人买吗？
