When the minimum wage is set above the equilibrium market wage, a. there will be an excess demand for labour at the minimum wage. b. it will have no effect on the quantity of labour employed. c. the unemployment rate will rise. d. the quality of the labour force will rise. 10. Taxes levied directly on consumers a. always hurt consumers rather than producers. b. always hurt producers rather than consumers. c. generate more revenue than taxes levied on producers. d. have the same effect as taxes directly levied on producers. 11. Refer to the Figure below. Consider the impact of a tax on sellers, shown in this diagram of the market for whisky.

4 12. Refer the figure below. This diagram shows the market for fish, in equilibrium at 20 per kilo. At this price consumer surplus is a b c d If marginal cost is greater than average total cost then a. profits are increasing. b. economies of scale are becoming greater. c. average total cost remains constant. d. average total cost is increasing. 14. Miller Technologies has average variable costs of 6 and average total costs of 10 when it produces 1,000 units of output. The firm's total fixed costs equal Name 4 / 10

5 a. 2,000. b. 3,000. c. 4,000. d. 5, Refer to the table below. This table describes the relationship between output, marginal revenue, and marginal cost. If the firm is currently producing 14 units, what would you advise them to do? a. decrease quantity to 13 b. increase quantity to 15 c. remain at 14 units d. increase quantity to 16 units Unit Marginal Marginal Quantity Cost Revenue Name 5 / 10

6 Part II: Short Answer Instructions: Show your work but do not exceed the space provided. Problem 1: There is a market with 8 buyers and 8 sellers. Each buyer can buy at most 1 unit, each seller can produce at most 1 unit. Buyer Willingness to Pay Seller Cost a) What is the quantity demanded when price is 50? What is the quantity supplied when price is 50? There is an excess of units when price is 50. When price is 50, 7 are supplied, 5 are demanded, and there is an excess supply of 2 units. b) Compute the equilibrium price and quantity. The equilibrium price is 45 and the equilibrium quantity is 6. c) Compute the consumers surplus and producer surplus at the equilibrium price. CS = (95-45) + (85-45) + (85-45) +(70-45) +(50-45) +(45-45) = 160 PS = (45-45) + (45-30) + (45-30) +(45-25) +(45-25) +(45-25) = 90 d) The government puts a minimum price (PRICE FLOOR) of 70. How many units of the good will be bought and sold with the minimum price? Compute the consumers surplus with the minimum price. 4 units are bought and sold (suppliers would like to sell 8 but buyers will only buy 4). CS = (95-70) + (85-70) + (85-70) +(70-70) = 55 Name 6 / 10

7 Problem 2: Suppose there are 20 million workers in Canada, and 40 million workers in the Turkey. Each of these workers in both countries can be employed either in car or wheat production. Workers to be employed to make 1 Car Workers to be employed to make 1 ton of Wheat Canada 20 2 Turkey 20 5 When there is no trade, each country prefers to distribute its workforce equally between the two industries a) Canada has an absolute advantage in the production of wheat. Turkey has comparative advantage in the production of cars. b) Fill in the follow table of opportunity costs Opportunity cost of 1 Car (in terms of tons of wheat) Opportunity cost of 1 ton of wheat (in terms of cars) Canada Turkey c) Draw the Production Possibilities Frontiers for Canada and Turkey, and indicate their final consumption of wheat and cars in the absence of trade. (all quantities in millions) Canada: PPF linear from (cars, wheat) = (1,0) to (0, 10). With workforce equally split, final consumption is (0.5, 5). Turkey: PPF linear from (cars, wheat) = (2,0) to (0, 8). With workforce equally split, final consumption is (1, 4). d) Suppose each country spends all its time producing the good in which it has a comparative advantage and trades half of its production with the other country at the price of 5 tons of wheat for 1 car. What are the final consumptions of Canada and the Turkey? Which countries benefit from trade, if any? Canada produces 10 (million tons) wheat and trades 5 for 1 (million) cars, giving final consumption with trade of (cars, wheat) = (1, 5). Turkey produces 2 (million) cars and trades 1 (million) for 5 (million tons) of wheat, giving final consumption with trade of (cars, wheat) = (1, 5). Canada has the same wheat consumption as without trade but more cars, so it is better off. Turkey has the same car consumption as without trade, but more wheat, so it is better off. Name 7 / 10
