Consider the global market for tin represented by Figure 7.4. Initially equilibrium is at point A with a market price of $3.50 per pound and 50,000 pounds. In order to keep tin price relatively stable an International Tin Agreement has set a price floor of $3.27 and a ceiling of $4.02. As the demand for tin increases to D1 how will the buffer-stock manager need to respond? Select one: a. buy 10,000 pounds of tin b. buy 20,000 pounds of tin c. sell 10,000 pounds of tin d. sell 20, 000 pounds of tin

- 1. The United States currently imports all of its coffee. The annual demand for coffee by U.S. consumers is given by the demand curve Q = 250 – 10P, where Q is quantity (in millions of pounds) and P is the market price per pound of coffee. World producers can harvest and ship coffee to U.S. distributors at a constant marginal (= average) cost of $8 per pound. U.S. distributors can in turn distribute coffee for a constant $2 per pound. The U.S. coffee market is competitive. Congress is considering a tariff on coffee imports of $2 per pound. a. If there is no tariff, how much do consumers pay for a pound of coffee? What is the quantity demanded? b. If the tariff is imposed, how much will consumers pay for a pound of coffee? What is the quantity demanded? c. Calculate the lost consumer surplus. d. Calculate the tax revenue collected by the government. e. Does the tariff result in a net gain or a net loss to society as a whole?Country C imports 80,000 metric tons of steel from Country U and produces domestically80,000 metric tons per year. The world price of steel is $500 per metric ton. Assuming linearschedules, research analysts estimated the price elasticity of domestic supply to be 0.50 and theprice elasticity of domestic demand to be -0.25 in the current market equilibrium. Country Cimposes an import duty of $150 per metric ton that caused the world price to fall by 10%. What are the terms of trade of the Country C steel market after the tariff was imposed? Explain the welfare effects of both countriesConsider a small (home) country with the following inverse demand of: P = 200 − 3QD and inverse supplyof: P = 20 + QS for a barrel of oil.

- Domestic demand for fidget spinners in the domestic economy is characterized by the equation P = 100 – 2Q, domestic supply is characterized by the equation Q = P – 10, and the world price is equal to 60. Then the export subsidy of 10 per unit will change nothing lead to a decrease in the world príce by 10 O increase domestic exports by 10 O increase domestic exports by 152. Suppose cheap mountain bikes are made in both the US and the Philippines.

- Consider the market for blueberries (a homogeneous product) in Madagascar, which is con- sidered a small country. Demand for a good is given by QD = 100– P. Domestic supply for the good is given by: Qs = P. Each country that exports blueberries has different marginal cost: $30 per crate in South Africa, $25 per crate in Peru, and $20 per crate in Chile. (a) Calculate the price, domestic output, consumption, imports, consumer surplus, and producer surplus associated with blueberries in the Madagascar free-trade equilibrium. (b) In the free-trade equilibrium, how many crates of blueberries are imported from each of the three source countries? (c) Calculate the price, domestic output, consumption, imports, consumer surplus, pro- ducer surplus, and government revenue associated with blueberries if Madagascar adopts a $15 MFN tariff on all WTO members. How many crates of blueberries are imported from each of the three source countries? (d) With the adoption of a Southern African Free Trade…The market for rice in an East Asian country has demand and supply given by QD = 28 – 4P and QS = -12 + 6P, where quantities denote millions of bushels per day. a. If the domestic market is perfectly competitive, find the equilibrium price and quantity of rice. Compute the triangular areas of consumer surplus and producer surplus. b. Now suppose that there are no trade barriers and the world price of rice is $3. Confirm that the country will import rice. Find QD, QS, and the level of imports, QD – QS. Show that the country is better off than in part (a), by again computing consumer surplus and producer surplus. c.

- You are provided with the following information about the Canadian turkey market:1. The world price of turkey is $5.2. The Canadian turkey market is currently (before the new trade agreement) protected by a tariffrate quota (TRQ) of the following format:a) the in-quota tariff is $1 per unitb) the import quota volume is 100 unitsc) the over-quota tariff is $10 per unit.3. An excess demand (ED) (for imports) function for turkey has been estimated as? = 28 − 0.14?. Notes: Canada is a small importing country in the world market for turkeys. Answer the question below: The Canadian government is considering reducing the in-quota tariff to $0.50. Modify the diagram for this market, and solve for the Canadian turkey price and the volume of imports. Label all relevant functions, axes, etc.Country A has a competitive domestic market of charcoal.
