Question 4: China is a large exporter of rare earths. The free trade price of a specific type of rareearth is $20 per unit. Let us say that China imposes an export tax of $4. This increases the international price of rare-earths to $23. The following are the domestic production and exports of rare-earth before and after the tax in China: Quantity produced in free trade: 10 million; Quantity exported in free trade: 4 million Quantity produced with tax: 8 million; Quantity exported with tax: 1 million a. Draw graphs for China and its trading partner to examine the welfare effects: (5 points) b. Calculate the following: (i) Change in Consumer Surplus. (3 points) (ii) Change in Producer Surplus.
