F 2.The total fixed cost of operating a lumberyard equals $12,000 this year. The average fixed cost of the lumberyard will not be affected by the quantity of lumber that is sold. F 3.Total cost equals total variable cost plus marginal cost. F. 4.The law of diminishing marginal product provides an explanation for why average total cost eventually increases as output is expanded in the short run. " 5.An externality is present whenever an activity has a physical impact (costs or benefits) on individuals not directly involved in the activity. 6.A cost that spills over onto individuals not directly involved in an activity is called a positive external ity. F 7. When negative externalities are present, it leads to an underallocation of resources in that area relative to that which is socially desirable. F 8.When positive externalities are present, it leads to an underallocation of resources in that area relative to that which is socially desirable. *T' 9.1f a negative externality results from the production of chemicals, an external cost is imposed on parties not directly involved in the market for the chemicals. 10. If mining companies are able to shift some of their production costs onto outside parties, the ‘ actual output of mines is likely to fall short of society's ideal. (/5 More {14's “LS/Ion) l l. Inoculation against communicable diseases is an example of an activity that generates positive externalities. 7' 12. Someone who does not contribute toward covering the cost of a good he desires, and yet he cannot be excluded from receiving the good, is called a free rider. T 13. A public good or service can be consumed by paying and nonpaying customers alike. T 14. An example of a public good is a flood control project that protects all the homes and properties near a river. T 15. Admission to Disney World is an example of a private good from which nonpaying individuals can be excluded. ‘7 MULTIPLE CHOICE 1) An explicit cost is: a _ an opportunity cost. @ an out-of—pocket expense. 0 always larger than an associated implicit cost. d) the total cost of acquiring or doing something, and therefore, includes all opportunity costs. e) both a) and b). 2) An implicit cost: a) is an opportunity cost. b) is an out-of-pocket expense. c) does not require an outlay of money. d) is characterized by both a) and b). is characterized by both a) and c). 3) Firms measure their profit by: a) the sum of total sales revenue. b subtracting total revenues from total costs. @subtracting total costs from total revenues. ) the total value of outstanding shares of stock. ’ 4) An economist‘s measurement of profit differs from an accountant‘s in that: a) accountants calculate total revenue differently than do economists. b) economists do not always include all of the opportunity costs when calculating total production costs. @accountants do not always include all of the opportunity costs when calculating total production costs. d) economic profit generally exceeds accounting profit. 5) Economists normally assume that the goal of a firm is to: a sell as many units of output as possible. émaximize profits. 0 sell products at the highest prices possible. d) maximize sales revenue. 6) An example of an explicit cost of production is: éthe cost of foregone labor earnings for an entrepreneur. the cost of flour for a baker. c the foregone rent that could have been earned if land owned by a firm was not used as its parking lot. d) provided by none of the above. 7) An example of an implicit cost of production is: a) the cost of raw materials used to produce bread in a bakery. b) the cost of labor in a factory that assembles DVD players. @the income an entrepreneur could have earned working for someone else. all of the above 8) Private costs are those borne by: a) the government. b the producer of an item. both an item’s producer and outside parties affected by a negative externality. d) outside parties affected by a negative externality. 9) External costs are those that are: a) borne by free riders. b borne by exporting firms. borne by parties not directly involved in a transaction. borne by the government. e) borne by the firm that creates a negative externality. 10) The total social costs of production are: ~' a) private costs plus private benefits. b private benefits minus private costs. private costs plus external costs. ‘ private costs minus external costs. 1 1) An example of a positive externality is: a) freeway congestion. b) pollution in a resort lake. 0 airport noise. beautiful trees on property along a parkway. 12) An externality occurs when: . people other than those making the demand and supply decisions share the benefits or the costs of an activity. b) only the people making the demand and supply decisions share the benefits or the costs of an activity. 0) private costs of production equal the full social costs associated with production of a good. d) private costs of production are ignored. 13) Costs that accrue to the total population are called costs.

Why is the point of diminishing marginal product different in each case? SHORT ANSWER 1. What are the external costs associated with cellular phone usage in automobiles? The external benefits? Answer: The external costs associated with cellular phone usage may include a higher incidence of traffic accidents. Not only are the individuals involved in the accident bearing additional costs, but so also are other insured drivers who now have to pay higher insurance rates. External benefits could include the ability to report an accident so that help can reach victims more quickly, and so that traffic reporters can advise motorists to avoid a particular area. 2. What is the difference between private and social costs? Answer: Social costs are those that accrue to the total population; private costs refer to those costs incurred only by the producer or consumer of the good or service. 3. Why do decision makers tend to ignore external costs? How can internalizing external costs move us closer to efficient levels of output? Answer: They ignore it because it is never a resource that they have to "purchase" for the production process. If an industry or a firm were somehow forced to compensate persons who incur the costs of pollution, we would say that the industry had internalized the externality. There would be greater social efficiency if all of the costs of production were internalized. The firms would produce less and charge a higher price, but it would then include all the costs. 4. What distinguishes public goods from private goods? Answer: Public goods are both nonrival in consumption (one person's consumption does not diminish another’s) and nonexclusive (you cannot prevent nonpaying individuals from benefiting from the good). Private goods are both rivalrous and exclusive. One's consumption of such a good does diminish another's, and you can keep nonpaying individuals from consuming the good or service. 5. Explain why broadcast television is considered a public good. Answer: Broadcast television is a good that is nonrivalrous and nonexclusive in nature. l.The R&J Ice Cream Company makes gallons of ice cream using the technology described below. Fill in the Marginal Product columns of these tables. When six ice cream makers are utilized each hour, at what point does diminishing marginal product set in? When eight ice cream makers are utilized? Why is the point of diminishing marginal product different in each case? ---— cream makers makers Marginal Total Labor ( (- ) Labor ( (- ) —_ —_ "—— "—— —_ _— — __ _ 134 144 Answer: Diminishing marginal product sets in with six machines once the fifth worker is hired each hour, and with eight machines not until the sixth worker is hired. When eight machines are used instead of six, more units of labor can be hired before crowding occurs. ---- cream makers makers Marginal Total Product Labor (, Labor , ) allons) ) - _ 4 4 2 1 8 2 mu 0 mu 0 2 4 14 — _ — 2. What is the law of diminishing marginal product? What causes it? Answer: The law of diminishing marginal product states that as the amount of a variable input is increased, while the quantity of other (fixed) inputs are held constant, a point will ultimately be reached beyond whichmarginal product will decline. 5. Explain why some costs are considered to be variable and some fixed. How does time enter into the definition? Answer: Some factors cannot be adjusted quickly in the short run. Costs associated with these factors are called fixed costs. Variable costs are costs incurred through the utilization of factors that can be readily varied in the short term (such as raw materials or labor). Variable costs are costs that increase as output increases, and decrease as output decreases. All costs are variable in the long run when firms have sufficient time to vary all factors of production. ...
