Regulation restrains the unfettered market power of firms. What are the legitimate reasons why government might choose to override the decisions made in free markets? a. b. c. d. 5. Let long lines and waiting times help balance supply and demand. Those willing to stay in line stay, those who aren’t leave. Let the children and elderly get care first, and then the middle-aged, and then young adults. Let the quality of customer service deteriorate. All of the above. Adverse selection occurs when: a. b. c. d. 4. perfect competition complete information no externalities no government to prevent abuses of market power by monopolies or oligopolies to remedy informational failures to encourage prices to exceed marginal cost both a and b A person who feels more pain from losing $2,000 than the pleasure from gaining $2,000 is: a. b. c. risk averse. risk loving. risk neutral. 1 6.

Based on your understanding of asymmetric information, why would you expect the price of a brand new car to fall immediately after it is bought and driven off the lot? a. b. c. d. 8. Because it is very expensive to bring the car back on the lot. It has to be washed and vacuumed and recertified. If the owner tried to sell it soon after she bought it, people will place a high probability that something is wrong with the car. The owner might be a smoker and the car might not smell as nice as when it is genuinely new. Speculators drive the price of a used car down. Suppose that the tax on an income of $20,000 is equal to $4,000. Assume, as well, that the tax would rise to $4,800 if this income were to rise to $22,000.

As health insurance premiums rise, some of the healthy decide to forgo insurance while the ill-proned continues to demand insurance. As government spending on health care increases, more government employees will seek jobs in the private medical profession.

According to the World Bank's most recent databook, the wealthiest 10 percent of Americans received 29.9 percent of the national income. The comparable figure for Japan was 21.7 percent; some other examples include 33.1 percent in China; 28.5 percent in the United Kingdom; 25.1 percent in France; 22.7 percent in Germany and 28.5 percent in India.

Problem-solving questions Consult Figure below to finish blanks in question 16 and 17. Curve SS represents a domestic supply curve for some good X; if X is a competitive industry, then SS represents the horizontal sum of the marginal cost curves of many firms. Curse DD represents domestic demand for the same good. It is implicitly assumed that consumers do not care where the good was made; they simply want to buy the indicated quantities at the indicated prices. 16. The market-clearing price in the absence of trade is $ A , and B units of X would be demanded and supplied domestically at that price. If the world price of $5 were allowed to prevail, though, then C units of X would be demanded, D units would be supplied domestically, and E units would be imported. (Round your answer to two decimal places unless it is an integer. Please do NOT include words or “$” in your answer.) Your Answers : A: $_______________ B: _______________units C: _______________units D: _______________units E: _______________units Now suppose that the domestic government has been convinced somehow to restrict imports by 50 percent. A tariff of $ F per unit imported would do the trick, but it would raise the domestic price to $ G . At that price, H units would be demanded, I units would be supplied domestically, and J units would be imported. (Round your answer to two decimal places unless it is an integer. Please do NOT include words or “$” in your answer.) Your Answers: F: $______________ G: $______________ H: _______________units I: _______________ units J: _______________ units 5 17. The effect of the tariff, therefore, is to A (raise / lower) the price of X, B (raise / lower) domestic production and employment, and C (raise / lower) imports. Given the tariff in question 16, the government would collect $ D in revenue; this is revenue that would be collected above and beyond the revenue that it collected from its domestic tax base. (Hint: To see the tax on your diagram, construct a box underneath the supply and demand curves. The length is the 7.5 units that are imported, and the height is the $2.50 tariff.) From the producer’s point of view, the higher domestic price would, however, promote E (less / more) efficient production at home, and thereby cause a production efficiency F (loss / gain) of $ G . The marginal cost of producing X at home would, quite simply, increase to a level 50 percent higher than the marginal cost incurred by the rest of the world. The domestic economy would, in other words, be wasting resources in the production of X that would have been employed more efficiently somewhere else. Your answers: A: ____________(raise / lower) B: ____________(raise / lower) C:_____________(raise / lower) D:$____________ E: ____________(less / more) F: ____________(loss / gain) G:$____________ If the government chose to impose a quota rather than a tariff, then it would award licenses to import up to H units of X. Your answer: H: _______________units (Round your answer to one decimal place.) If there were no tariff, but if it costs $2.50 per unit to transport X from the world marketplace into the domestic economy, then your answers for Question 16, blank G through J I (would / would not) be altered. The revenue in Question 17, blank D identified as going to the government J (would / would not) simply go to the transport company. Your answers: I: _______________(would / would not) J: _______________(would / would not) 6 18. Refer to the graph below and answer the question below. (Round your answer to two decimal places unless it is an integer. Please do NOT include words or “$” in your answer.) a. What is the equilibrium price if the demand curve is for a perfectly competitive industry? Your answer: _______________ b. What is the price if the graph describes a monopoly? Your answer: _______________ c. How much is the monopoly rent? Your answer: _______________ d. How much is the economic waste or deadweight loss? Your answer: _______________ 7 19. Refer to the graph below. What is amount of total deadweight losses caused by the tariff? (Round your answer to two decimal places unless it is an integer. Please do NOT include words or “$” in your answer.) Your answer: _______________ Part III. 20. Essay(s) Discuss the important functions of speculators. Why might it be efficient to support the efforts of these people, even though they produce no output in the economy? 8 Assignment 4 Part I.Multiple-choice questions 1.

Economists refer to the “break-even point” for a competitive firm. This break-even point in the short run occurs at the output level where: a. b. c. d. e. marginal cost (MC) equals average cost (AC). average variable cost (AVC) equals average fixed cost (AFC). MC equals AVC. AC equals AVC. MC equals AFC. 1 7. If a firm is operating at the shutdown point in the short run, it is: a. b. c. d. just covering all fixed cost. just covering all cost. just covering all variable cost. just covering marginal cost. 8. The profit-maximizing rule for a firm in perfect competition is “marginal cost equals price”. This rule means that a firm should: a. b. c. d. increase output until price has risen to equal marginal cost. increase output until price has fallen to equal marginal cost. increase output until marginal cost has fallen to equal price. increase output until marginal cost has risen to equal price. 9. A firm operating in circumstances of perfect competition faces a market price of $10. It is producing 2,000 units of output daily at a total cost of $19,000. This firm: a. b. c. d. should increase its output to improve its profit position. should reduce its output to improve its profit position. should shut down to minimize its loss. may or may not be at the output level yielding maximum profit—the information furnished is not sufficient to cover this point. 10. Because of a city tax reduction, the total fixed cost a firm must pay is reduced by $500 monthly. The firm operates in conditions of perfect competition. If the firm seeks to maximize its profit, this cost reduction should (at least in the short run) result in: a. b. c. d. e. a reduction in price. an increase in output. an increase in price. a reduction in output. no change in output or in price. 11. A firm operating in a perfectly competitive industry is producing a daily output which supports total revenue equal to $5,000. That output is its profit-maximizing output. The firm’s average total cost is $8, its marginal cost is $10, and its average variable cost is $5. Its daily output is: a. b. c. d. 200 units. 500 units. 625 units. 1,000 units. 2 12. The (total) fixed cost for the firm described in question 11 is: a. b. c. d. $10. $100. $500. $1,500. 13. A firm must sell its product at a market price of $1.90. Its present operating figures are as follows: average cost, $2.00; marginal cost, $1.50; average variable cost, $1.50; total fixed costs, $500 per period. By the rules of maximum profit (or minimum loss) for a competitive firm, this firm would: a. b. c. d. increase its present output level. reduce its present output level. remain at its present output position. shut down. Use the figure below to answer Question 14 through 16. 14. The producer surplus in this perfectly competitive market (when the equilibrium price=$50 and the equilibrium quantity=50) is: a. b. c. d. $0 $100 $1,000 $1,250 15. The total surplus in this perfectly competitive market (when the equilibrium price=$50 and the equilibrium quantity=50) is: a. $0 b. $100 c. $1,000 d. $2,500 16. If the government imposes a price ceiling of $40 on the market illustrated in the figure above, producer surplus in this perfectly competitive market will fall to: (Hint: when P=$40, Q=40) a. b. c. d. $100 $500 $800 $1,000 3 II. Problem-solving questions Use the following information for Question 17 through 20. Suppose the world is consisted of two countries, Country A and Country B, whose supply and demand for a particular product are given as follows: Country A: Supply function: Qs ,a  4  2 Pa Demand function: Qd ,a  18  2 Pa Country B: Supply function: Qs ,b  3  Pb Demand function: Qd ,b  12  Pb 17.
