今日知識點：Analysis of trade

例題

Without trade, PD = $3000, Q = 400; in world markets, PW = $1500

Under free trade, how many TVs will the country import or export?

Identify consumer surplus, producer surplus, and total surplus without trade, and with trade.

---

解析

Under free trade,

• domestic consumers demand 600
• domestic producers supply 200

imports = 400

Without trade,

CS = A

PS = B + C

Total surplus = A + B + C

With trade,

CS = A + B + D

PS = C

Total surplus = A + B + C + D

下面我們為大家準備了一道同類型的題目，請大家一起來試試解答。

Consumers must pay $30 for an imported shirt. So, domestic producers can charge $30 per shirt.

In general, the price facing domestic buyers & sellers equals (PW + T).
