In autarky, the price of shoes in country A is $40, and the equilibrium quantity is 1,000 units. After trade liberalization, country A starts exporting shoes at the world price of $90. Its consumption goes down to 600 units while the production rises up to 1,800 units. i) Draw a graph to illustrate the scenario above. (8 points) Price $90 S $40 D 0 600 1,000 1,800 Quantity ii) Calculate the change in consumer surplus, producer surplus, and total welfare in country A following trade liberalization. (12 points) CS = - (90 - 40) x (1,000 +600)/2 =- $40,000 PS = ( 90-40) x (1,000+ 1,800)/2 = $70,000 TW = CS + PS = -$40,000+$70,000=$30,000 2008 Spring ECON 333 Prepared by Lu Pan 2.

As a result, country M starts imposing a tariff of 150% on piano imports. Annual piano consumption goes down to 60 units while annual domestic production jumps to 30 units. i) Draw a graph illustrating the scenario above. (8 points) Price S $2000 Tariff Price after Tariff $800 Imports after tariff D World price Free Trade Imports 0 25 30 60 100 Quantity ii) Calculate the following: change in consumer surplus, change in producer surplus, tariff revenue, production distortion cost, consumption distortion cost, net change in welfare.
