3. The demand and supply of a commodity are estimated by the following equations: P = 1,000 - 0.005Qd P = 200 + 0.005Qs a) Calculate the equilibrium price and quantity. b) Plot the demand and supply curves and illustrate the equilibrium price and quantity. c) If the world price (Pw) is $500, calculate the quantity of imports, the consumer surplus, and the producer surplus. d) Now suppose the government wants to restrict the quantity of imports to 20,000 through a quota: i) Calculate the new price. ii) Calculate the deadweight loss and illustrate it in your diagram. e) If the government restricts imports to 20,000 through a tariff instead, what would be the amount of the tariff and the corresponding deadweight loss
