In2020, Chinese government imposed import restrictions targeting Australia's coal. Who would be hurt by these policies? (A) Coal miners in China (B) Coal miners in Russia (C) Electricity consumers in India (D) Electricity consumers in China
12. Assume that two countries A and C can produce both timber and cars. The country A can produce 20 units of timber or 8 units of cars in one week； the country C can produce 15 units of timber or 4 units of cars in one week.

13. In the clothes market of Bangladesh, all clothes producers are price-takers. These clothes producers make tons of water pollution. Assume that the Bangladesh government decides to impose a one-time tax to each clothes producer in 2021； the payment for each producer depends on their production in2019. In the short run, what will happen to the equilibrium price and quantity of the clothes market in Bangladesh after this policy? (A) The equilibrium quantity and price will both decrease. (B) The equilibrium quantity will decrease, but the equilibrium price will increase. (C) The equilibrium quantity will decrease, but the equilibrium price will be uncertain. (D)The equilibrium quantity and price will not change.
14. In the cabbage market of Taiwan, most cabbage sellers are price-takers. In this month, assume that in the equilibrium, the demand has an own-price elasticity of -1.5, and the supply has a price elasticity of 0.75. Suppose a per-unit tax of NT3, to be collected from sellers, is imposed in the market in this month. For the tax of NT3, which answer below is the possible amount of tax that will be shifted to the buyers?(A) 2(B) 1.5(C)1(D)0
15. Which of the following statements is correct regarding profit-maximizing firms in the long run? (A) In perfect competition, firms produce an output at which price is less than marginal cost. (B) In perfect competition, firms produce an output at which price is greater than marginal cost. (C) In monopolistic competition, firms produce less than the output at which average total cost is minimized. (D) In monopolistic competition, firms produce more than the output at which average total cost is minimized.
16. Suppose that there is a global market of X. In the country T, the producers for X are price-takers, and there is no domestic consumers； they export all X they produce. The international price for X is $50 per unit. The private total cost function for a firm in T to produce X is 400+0.01Q, where Q is the units of X the firm produces. Recently, the government finds that producing X also causes external costs, which are around $10 per unit. Which policy below can correct this market failure, and achieve the social optimum in the country T? (A) The government can impose a per-unit tax of $5 on producers in T. (B) The government can request each producer in T to reduce their production by 500 units. (C) The government can set 1000 units as an upper bound on the production of each producer.(D) The government can request each producer to export at least 500 units. 
17. U is a monopoly producer for a special device； yet, they do not have a sales department. In a small town K, there are two retailers, D1 and D2, selling this device. U proposes a take-it-or-leave-it offer for D1 and D2； then, D1 and D2 engage in Bertrand price competition. The total demand in this town for the special device is Q(P) = 1000-5P. The average variable cost for U to produce this device is 45. While selling devices, D1 and D2 will not incur additional cost. No fixed cost for U, D1 and D2. The retailing price or the wholesale price can be only an integer. What is the possble retailing price in which D1 sells this special device? (A) 46 (B) 92 (C) 123 (D) 161
18. Refer to Problem 17. Now, assume that U acquires D1； that is, U and D1 become one company. U still proposes a take-it-or-leave-it offer for D2； then, D1 (or U) and D2 engage in Bertrand price competition in the retailing market. Other conditions remain the same. Under this setup, which statement below is wrong? (A) D2 cannot earn a profit bigger than zero in all equilibria. (B) D2 cannot sell any device in all equilibria. (C) The retailing price set by D1 can be higher than the retailing price set by D2 in an equilibrium. (D) The retailing price set by D1 can equal the retailing price in Problem 17 in an equilibrium.
