1.Tariffs: The domestic demand curve for portable radios in Canada is given by Qd = 5000 100P. where price P is measured in (Canadian) dollars and quantity Q is measured in radios per year. The domestic supply of radios from Canadian producers is Q5 2 100P a. What are the domestic (no trade) equilibrium values of P and Q in this market? b. Suppose portable radios can be imported at a world price of $10 per radio, and this supply of imports is perfectly elastic at this price. If trade were allowed, what would the new market equilibrium price be in Canada? How many radios would be produced domestically? How many would be imported? c. Suppose Canadian radio manufacturers successfully lobby the federal government to institute a tariff of $5 on each imported radio. Graph the market with this tariff in place. What is the equilibrium price in Canada after the tariff is implemented? How much tax revenue is collected? Clearly identify on the graph the change in (domestic) consumer surplus, the change in (domestic) producer surplus, and the deadweight loss due to the tariff (you don't need to calculate these values). (1. Suppose that the protection provided by this tariff enables domestic producers to become more highly efficient, so that the domestic supply curve shifts to Q3 2 200P e. Let the tariff remain in place. What is the equilibrium price now? How much tariff revenue is collected? What is the total volume of radios sold, how many are domestically produced, and how many are imported
