II. Consider a planet called Nemo whose firms operate under perfect competition. Suppose that the market demand curve is given by P = 45- 2Q, and the market supply curve is given by P=9+20.. Nemo is considering using an import tariff of t = 3. a) Compute the intercept of the import demand curve (hint: invert market demand and supply, M=Q.-Q.) b) Compute the absolute value of the slope of the import demand curve. For c to e, suppose export supply is perfectly elastic at PW = 20 c) Compute consumer surplus in autarky. d) Compute the consumer surplus in free trade. e) Compute the increase in consumer surplus from autarky to free trade. f) Compute the increase in consumer surplus from autarky to the tariff outcome. g) Given this export supply curve, Nemo should: a. Remain in autarky b. Open up to trade without the tariff c. Open up to trade with the tariff of t = 3
