Question 1 Use the following information to answer questions 1, 2 and 3: The demand for coal briquettes is given by the following: p=200-0.5*Q. The private marginal cost of coal briquettes is given by the following: MC=20+0.5Q. In addition, there is an external cost of coal briquettes (E) to residents who live near the coal mine given by the following: E=Q. The socially optimal level of coal production is: 30. 90 110. 180. none of the above. Question 2 If the market for coal briquettes is competitive, the deadweight loss to society is equal to: 0. 4500. 8100. 9000. None of the above. 1 points Question 3 A Pigouvian tax of _______ on coal production will ensure the efficient outcome is achieved: 0. $45. $90. $135. $180. Question 4 Consider the following game. Roger and Jemima are roommates who must make decisions about cleaning. Roger’s payoff is the first number in each cell and a higher number is a better outcome: Jemima Clean Don’t clean Roger Clean ( 6, 10 ) ( 2, 6 ) Don’t clean ( 6, 4 ) ( 4, 0 ) This game has no Nash equilibrium. This game has a single Nash equilibrium. This game has more than one Nash equilibrium. Both Roger and Jemima have a strictly dominant strategy. both b and d are correct. Question 5 Assume that there is a world price for corn and that the domestic market has the usual downward sloping demand curve and upward sloping supply curve. Which of the following statements is true for a country that exhibits an absolute disadvantage in the production of corn? The country will import corn and consumer surplus will increase relative to the no trade situation. The country will import corn and producer surplus will increase relative to the no trade situation. The country will export corn and consumer surplus will increase relative to the no trade situation. The country will export corn and producer surplus will increase relative to the no trade situation. More information is required. Question 6 Which of the following statements about markets and the problem of externalities is (are) true? Externalities generally lead to an inefficient level of consumption and or production The inefficiency caused by an externality may be resolved by appropriately defining property rights Taxes or subsidies may be used to correct the inefficiency caused by an externality Even for a negative externality such as pollution, efficiency generally requires a positive level of pollution All of the above. Question 7 Which of the following statements is (are) true? Individuals have a demand for public goods and competitive markets supply an efficient amount. A demand curve for public goods is the horizontal sum of the demand curves of each individual. A demand curve for public goods is the vertical sum of the demand curves of each individual. Efficiency for a public good requires that the marginal benefit for each individual equals the marginal cost of producing the public good Both c. and d. Question 8 Bob has a demand curve for public broadcasting (denoted by G) given by the following: G = 9 – 0.5p. Similarly, Christine has a demand curve given by the following: G= 7 – p. Assume that the marginal cost of providing every hour of broadcasting is equal to 6. The efficient number of hours supplied equals: 0. 4. 5. 7. 10. Question 9 Two shops in Newtown, “Artisan Pens” and the Thrift Shop, are deciding whether to hire a security guard. The security guard represents a public good in that the guard will provide deterrence to both stores. The cost of hiring a guard is $20 in total or $10 per store if the cost is shared. Each store will benefit from the presence of a security guard by reducing theft by $12. The payoffs for the Thrift Shop are shown first in each cell. If the payoff matrix is given by: Artisan pen store Hire Do not hire Thrift shop Hire 2, 2 -12, 8 Do not hire 8, -12 0, 0 In the Nash equilibrium: A guard will be hired. No guard is hired. One store hires the guard and both benefit from the presence of the guard. Neither player has a dominant strategy and there are no Nash equilibrium. More information is required to answer the question. Question 10 Australia is a small open economy (a price taker) that imports televisions, an internationally traded commodity.

The domestic price of TVs ______ and imports _______. falls, increase. falls, decrease. remains unchanged, increase. remains unchanged, decrease. none of the above. Question 11 Which one of the following is true for a competitive market? For a private good everyone can consume the same amount but the marginal valuation on the last item consumed may be different for different individuals. For a private good everyone can consume a different amount and the marginal valuation on the last item consumed is different for different individuals. For a public good everyone consumes the same amount and the marginal valuation on the last item consumed is the same for all individuals. For a public good everyone can consume a different amount and the marginal valuation on the last item consumed is the same for all individuals. None of the above. Question 12 Consider the following sequential game in which BHP and Rio can make a decision to make a large (L), medium (M) or small (S) investment. Note that BHP makes it decision first and that the payoffs represent profits. What is the Nash equilibrium of this game? BHP plays S; Rio plays L. BHP plays M; Rio plays L. BHP plays S; Rio plays M. BHP plays L; Rio plays L. None of the above. 1 points Suppose individuals A and B have the following demand curves for a public good: QA = 40 – 2p and QB = 40 – p, where Q is the amount of the public good. If the marginal cost of production is constant and equal to 30, the quantity produced in the competitive equilibrium would equal ____ and the efficient outcome is equal to ____: 0, 10. 10, 10. 10, 20. 10, 30. None of the above. Question 14 Which of the following statements is true?

A public good is non excludable. a and b are correct but c is incorrect. a, b and c are correct. Question 15 Which of the following statements is true? Common property resources can be characterised as an externality because individuals compare only the private marginal benefits and costs when deciding how much to use the common resource. A common property resource is non excludable. A common property resource is non rivalrous. Both a and b are correct but c is incorrect. a, b and c are correct. Question 16 Questions 16, 17 & 18 refer to the following situation: Assume that the domestic demand for cars is given by Qd=8000-2P and the domestic supply of cars is given by Qs=P-1000.

In this assignment, you will practice additional methods of essay development.  Please write five short entries.  In your first, use cause and effect.  In your second, practice contrast.  In your third, define something. In your fourth, practice division-classification.  And finally, in your last present an argument.  I’ll leave you some prompts below. 

This five-parted assignment should be created as a single Word document.  When complete, please upload to be graded using the dropbox below. 

Part I:  Write Cause and Effect:  What are the CAUSES of  you becoming an online student (the effect)?

Part II:  CONTRAST two things, any two things you’d like.  You might contrast cats/dogs; online school/traditional school; glasses/contacts; soccer/football

Part III: DEFINE yourself in some way.  Are you an adventuer?  A mother?  A father?  A sister?  What does it mean to play this role?

Part IV: DIVIDE and CLASSIFY something. Think music, vacations, food, pets, technology…

Part V: Create a short ARGUMENT about something you feel passionate about.  Here’s an example from your textbook, though you can feel free to use something else: 

“Junk food is available in school cafeterias and school vending machines, and the cafeteria menus do not encourage the best eating habits.  But good education should include good examples as well as classwork.  Schools should practice what they preach about a healthy diet and stop providing junk food.”

Each part of this assignment is worth up to six points and should be composed in at least one-developed paragraph.
