The slope of an indifference curve reveals:a.that preferences are complete.b.the marginal rate of substitution of one good for another good.c.the ratio of market prices.d.that preferences are transitive.e.none of the above.2. Jane is trying to decide which courses to take next semester. She has narroweddown her choice to two courses Econ 1 and Econ 2. Now she is having trouble.She just cannot decide whi ch of the two courses to take. It’s not that she isindifferent between the two courses, she just cannot decide. An economistwould say that this is an example of preferences that:a.are not transitive.b.are incomplete.c.violate the assumption that more is preferred to less.d.all of the above.3. If a consumer must spend her entire income on some combination of twocommodities and chooses to spend it all on just one of the commodities then:a.the other commodity is an economic bad.b.the other commodity must have zero marginal utility.c.the other commodity generates less utility per dollar spent on the good.d.the two commodities must be perfect substitutes.4. The change in the price of one good has no effect on the quantity demanded ofanother good. These goods are:plements.b.substitutes.c.both inferior.d.both Giffen goods.e.none of the above.5. The income-consumption curve for Dana between Q A and Q B is given by theequation Q A = Q B. His budget constraint is given as:120 = Q A + 4Q BHow much Q A will Dana consume to maximize utility?a.0.b.24.c.30.d.60.e.More information is needed to answer this question.6. Assume that beer is a normal good. If the price of beer rises, then thesubstitution effect results in the person buying ______ of the good and theincome effect results in the person buying ______ of the good.a.more, more.b.more, less.c.less, more.d.less, less.7. Which of the following will cause the price of beer to rise?a. A shift to the right in the demand curve for beer.b. A shift to the left in the supply curve of beer.c.both (a) and (b).d.none of the above.8. Blanca would prefer a certain income of $20,000 to a gamble with a 0.5probability of $10,000 and a 0.5 probability of $30,000. Based on thisinformation:a.we can infer that Blanca neutral.b.we can infer that Blanca is risk averse.c.we can infer that Blanca is risk loving.d.we cannot infer Blanca's risk preferences.Wanting to invest in the computer games industry, you select Whizbo, Yowzo and Zowiebo as the three best firms. Over the past 10 years, the three firms have had good years and bad years. The following table shows their performance:9. Refer to the table above. Where is the highest expected revenue, based on the10 years' past performance?a.Whizbo.b.Yowzo.c.Zowiebo.d.Whizbo and Yowzo.e.Yowzo and Zowiebo.10. The price of good A goes up. As a result the demand for good B shifts to theleft. From this we can infer that:a.good A is used to produce good B.b.good B is used to produce good A.c.goods A and B are substitutes.d.goods A and B are complements.e.none of the above.11. A firm uses two factors of production. Irrespective of how much of each factoris used, both factors always have positive marginal products which imply thata. isoquants are relevant only in the long run.b. isoquants have negative slope.c. isoquants are convex.d. isoquants can become vertical or horizontal.e. none of the above.12. A firm's marginal product of labor is 4 and its marginal product of capital is 5.If the firm adds one unit of labor, but does not want its output quantity tochange, the firm shoulda. use five fewer units of capital.b. use 0.8 fewer units of capital.c. use 1.25 fewer units of capital.d. add 1.25 units of capital.13. If input prices are constant, a firm with increasing returns to scale can expecta. costs to double as output doubles.b. costs to more than double as output doubles.c. costs to go up less than double as output doubles.d. to hire more and more labor for a given amount of capital, since marginalproduct increases.e. to never reach the point where the marginal product of labor is equal tothe wage.14. Which of the following is not an expression for the cost minimizing combinationof inputs?a. MRTS = MP L / MP K.b. MP L / w = MP K / r.c. MRTS = w / r.d. MP L / MP K = w / r.e. None of these.15. A firm wants to minimize the total cost of producing 100 tons of dynamite. Thefirm uses two factors of production, chemicals and labor. The combination of chemicals and labor that minimizes production costs will be found wherea.the marginal products of chemicals and labor are equal.b.the ratio of the amount of chemicals used to the amount of labor usedequals the ratio of the marginal product of chemicals to the marginalproduct of labor.c.the ratio of the amount of chemicals used to the amount of labor usedequals the ratio of the price of chemicals to the wage rate.d.the production of an additional unit of dynamite costs the same regardlessof whether chemicals or labor are used.e.none of the above.16. A firm employs 100 workers at a wage rate of $10 per hour, and 50 units ofcapital at a rate of $21 per hour. The marginal product of labor is 3, and themarginal product of capital is 5. The firma. is producing its current output level at the minimum cost.b. could reduce the cost of producing its current output level by employingmore capital and less labor.c. could reduce the cost of producing its current output level by employingmore labor and less capital.d. could increase its output at no extra cost by employing more capital andless labor.e. both (b) and (d) are true.17. When an isocost line is just tangent to an isoquant, we know thata.output is being produced at minimum cost.b.output is not being produced at minimum cost.c.the two products are being produced at the least input cost to the firm.d.the two products are being produced at the highest input cost to the firm.18. If current output is less than the profit-maximizing output, then the next unitproduceda.will decrease profit.b.will increase cost more than it increases revenue.c.will increase revenue more than it increases cost.d.will increase revenue without increasing cost.e.may or may not increase profit.19. If a graph of a perfectly competitive firm shows that the MR = MC point occurswhere MR is above AVC but below ATC,a.the firm is earning negative profit, and will shut down rather thanproduce that level of output.b.the firm is earning negative profit, but will continue to produce whereMR = MC in the short run.c.the firm is still earning positive profit, as long as variable costs arecovered.d.the firm is covering explicit, but not implicit, costs.e.the firm can cover all of fixed costs but only a portion of variable costs.20.When the price faced by a competitive firm was $5, the firm produced nothingin the short run. However, when the price rose to $10, the firm produced 100 tons of output. From this we can infer thata.the firm's marginal cost curve must be flat.b.the firm's marginal costs of production never fall below $5.c.the firm's average cost of production was less than $10.d.the firm's total cost of producing 100 tons is less than $1000.e.the minimum value of the firm's average variable cost lies between $5and $10.Part B: Problems (20 marks - Answer BOTH questions)1. (10 marks)Mark derives utility from attending rock concerts (R) and fromcolas (C) as follows:U(C,R) = C 0.9R 0.1.The marginal utility of cola (MU C) and the marginal utility of rock concerts(MU R) are given as follows:MU C = 0.9C −0.1R 0.1 ,MU R = 0.1C 0.9R−0.9 ,withMRS = MU C/ MU R = 9R / C.a.If the price of cola (P C) is $1 and the price of concert tickets (P R)is $30 and Natasha's income is $300, how many colas and ticketsshould Natasha buy to maximize utility? (4 marks)b.Suppose that the promoters of rock concerts require each fan tobuy 4 tickets or none at all. Under this constraint and given theprices and income in (a), how many colas and tickets shouldNatasha buy to maximize utility? (4 marks)c.Is Natasha better off under the conditions in (a) or (b)? Explainyour answer. (2 marks)2.(10 marks)Consider a competitive market made up of a large number ofidentical firms. The market demand curve for the product is:Q = 1,000 – 50P,where P is price and Q is quantity. The market supply is expressed as:Q = 200P– 1,000.A typical firm in the industry has a marginal cost function as follows:MC = 5 + 0.5Q.a.Determine the market equilibrium price and quantity for theindustry.
