Why are economic agents concerned with the allocation of these resources?Answer:Scarce resources are resources for which the quantity that agents want exceeds the quantitythat is freely available. Economic agents need to satisfy their unlimited wants in a world of limitedresources. This makes it important for them to understand how these scarce resources are to be used anddistributed in order to optimize allocation.Difficulty:EasyAACSB:Analytical ThinkingTopic:Economic Agents and Economic Resources7) Define economics. Who are economic agents?Answer:Economics is the study of how agents choose to allocate scarce resources and how these choicesaffect society.

It is analysis that describes what people actually do. "A 5 percent fallin the unemployment rate will lead to a 2 percent increase in the inflation rate" is an example of a positiveeconomic statement. In contrast, normative economics is analysis that prescribes what an individual orsociety ought to do. It is subjective and depends on personal preferences, tastes, attitudes, feelings, orethical judgments. "Pollution in developing countries is one of the biggest global environmentalproblems" is an example of a normative economic statement.Difficulty:EasyAACSB:Analytical ThinkingTopic:Positive Economics and Normative Economics21) Robert and Janet are discussing the unemployment and inflation in their country. Robert, on the basisof a recent newspaper report, claims that a 5 percent reduction in unemployment will lead to a 2 percentrise in inflation. In contrast, Janet insists that inflation is a far bigger problem than unemployment andshould be considered as of prime importance. Classify Robert's and Janet's statements as descriptive oradvisory. Explain your answer.Answer:Robert claims that a 5 percent reduction in unemployment will lead to a 2 percent increase ininflation. This statement represents predictions that can be verified with data. Therefore, Robert'sapproach is positive, which means it is an analysis of things as they are. Positive economics describeswhat has happened or predicts what will happen. The conclusion of his statement can be verified withdata and is not subject to tastes and preferences.Janet claims that inflation is a far bigger problem than unemployment and should be addressed as anissue of prime importance. Janet's statement is normative. Normative economics is analysis thatrecommends what people ought to do. Unlike Robert's statement, Janet's belief that inflation is a biggerproblem than unemployment is based on her values or ethical judgments. Therefore, while Robert'sstatement is descriptive in nature, Janet's statement is advisory.Difficulty:MediumAACSB:Application of KnowledgeTopic:Positive Economics and Normative Economics

In contrast, macroeconomics is the study of the economy as a whole. The scope ofmacroeconomics extends to the study of economy-wide phenomena, like the growth rate of an economy,the national unemployment rate, or the inflation rate.Difficulty:EasyAACSB:Analytical ThinkingTopic:Microeconomics and Macroeconomics36) A recent news report stated that the unemployment rate in the country of Lithasia had increased from10.2 percent to 18.2 percent between 2003 and 2013 and that the government has adopted strict fiscalmeasures to expand employment. Would this report be considered microeconomic or macroeconomicanalysis?Answer:This report pertains to macroeconomics. Macroeconomics refers to the study of an economy asa whole. Macroeconomics covers economy-wide phenomena, like the growth rate of a country's totaleconomic output, the inflation rate, or the unemployment rate.Difficulty:MediumAACSB:Application of KnowledgeTopic:Microeconomics and Macroeconomics37) Students in a class are discussing how a firm that does not face any competition in a market shoulddecide how many units of output to supply in the market. Would this discussion be consideredmicroeconomic or macroeconomic analysis?Answer:Microeconomics is the study of how individuals, households, firms, and governments makechoices. The students are discussing how a firm should make its output decision. This is a discussionabout an individual entity and so is considered microeconomic analysis.Difficulty:MediumAACSB:Application of KnowledgeTopic:Microeconomics and Macroeconomics

How are budget constraints related to trade-offs?Answer:Trade-offs occur because of scarcity–economic agents need to satisfy their wants with limitedresources. Therefore, in most cases, some benefits have to be given up to gain other benefits. Budgetconstraints quantify the relevant trade-offs that an economic agent faces. Once trade-offs are quantified,rational decision making becomes easier, allowing the individual to make an optimal decision.Difficulty:EasyAACSB:Analytical ThinkingTopic:Trade-offs and Budget Constraints15) The best alternative use of a resource is referred to as its ________.A) optimization costB) market priceC) social costD) opportunity costAnswer:DDifficulty:EasyAACSB:Analytical ThinkingTopic:Opportunity Cost16) A student has two options: she can either surf the web or work part-time.

What isthe student's opportunity cost of taking the first job?Answer:Opportunity cost is the best alternative use of a resource. It is what an economic agent is givingup when he chooses a particular option. If the individual decides to take the first job, he will earn $35,000a year. The opportunity cost of taking this job is the next-best offer that he could have taken.

What is the consumer's opportunity cost of buying a rug? What is his opportunitycost of buying a chair? Use a table to represent the consumer's budget constraint.Answer:Opportunity cost is the best alternative use of a resource. Buying one rug costs $10, and eachchair costs $5. One rug can be purchased with the same amount of money used to buy two chairs.Therefore, the opportunity cost of buying a rug is 2 chairs. Similarly, the opportunity cost of buying achair is half a rug. The consumer's budget constraint is given by:$100 = 10 × (Quantity of rugs) + 5 × (Quantity of chairs).The following table shows the various combinations of rugs and chairs that the consumer can buy with$100:BudgetQuantity of RugsQuantity of Chairs10010010092100841007610068100510100412100314100216100118100020Difficulty:MediumAACSB:Application of KnowledgeTopic:Opportunity Cost20) Sam pays $600 for 30 days of guitar classes. He attends an hour-long class every day. If, instead ofattending class, he works at a part-time job, he would be paid $5 an hour. Alternatively, he could work ata fast-food outlet and earn $9 per hour. Once he has already paid a nonrefundable fee of $600 to enroll inthe class, what is his opportunity cost of attending each hour of class?Answer:Sam's opportunity cost will measure the next best use of an hour of his time plus the hourlycost of guitar classes. Once he pays the nonrefundable $600, there is no further cost other than the valueof his time. For an hour of time, he has two options: work for $5 per hour or work for $9 per hour.Therefore, the next best use of an hour that Sam spends on guitar classes is equal to the $9 he could haveearned per hour by working at the fast-food outlet.

What could explain this behavior?Answer:With an increase in their hourly wage rates, workers work more and consume less leisurebecause of a change in their opportunity cost. Assuming that the initial wage of an employee is $10 perhour, the opportunity cost of one hour of rest or leisure is $10 per hour. If the wage rate increases from$10 to $20 per hour, the opportunity cost of one hour of rest or leisure also increases to $20 per hour.Therefore, taking an hour of rest becomes more expensive for employees, and so the workers tend towork more than they used to.Difficulty:MediumAACSB:Application of KnowledgeTopic:Opportunity Cost22) ________ is a calculation that adds up the costs and benefits using a common unit of measurement,like dollar values.A) Cost-benefit analysisB) Revenue-income analysisC) Budget constraint analysisD) Expenditure-income analysisAnswer:ADifficulty:EasyAACSB:Analytical ThinkingTopic:Cost-Benefit Analysis23) Cost-benefit analysis requires ________.A) choosing the alternative with the least net benefitB) that all costs and benefits be measured in the same unitC) evaluating the budget constraint before making a choiceD) that the risks associated with different alternatives be ignoredAnswer:BDifficulty:EasyAACSB:Analytical ThinkingTopic:Cost-Benefit Analysis24) Suppose that Jinelle, an engineer, has to choose between two jobs.

Test Bank for Microeconomics, 2nd Edition - Page 22 preview image2136) Wendy has to decide between taking a flight and driving to California. Air tickets cost $800 and willget her to California in 2 hours. If she decides to drive, she would need $300 worth of gasoline and 10hours to reach her destination. Suppose Wendy's opportunity cost of time is $20 per hour.a) Assuming that there are no other costs involved, use cost-benefit analysis to decide whether she shouldfly or drive to California.b) If Wendy has an important business meeting to attend and this increases her opportunity cost of timeto $200 per hour, will her optimum decision change? Explain.Answer:a) Cost-benefit analysis is a calculation that adds up costs and benefits using a common unit ofmeasurement. It is used to identify the alternative that has the greatest net benefit, which is equivalent tobenefits minus costs. If Wendy decides to drive down instead of flying, she saves ($800 − $300) = $500. Butdriving down to California takes an additional 8 hours of travel time. Therefore, the net benefit of drivingrelative to flying is:($500 Cost saving) − (8 hours Additional travel time) × ($20/hour) = $500 − $160 = $340. Because the netbenefit of driving is positive, driving to California is the optimum choice for Wendy when theopportunity cost of time is $20 per hour.b) If the opportunity cost of time changes, the net benefit of driving relative to flying will also change: Netbenefit of driving relative to flying when the opportunity cost of time is $200 per hour = ($500 Costsaving) − (8 hours Additional travel time) × ($200/hour) = $500 − $1,600 = −$1,100.Because the net benefit of driving relative to flying is negative, flying to California is the optimum choicefor Wendy when the opportunity cost of time is $200 per hour.Difficulty:MediumAACSB:Application of KnowledgeTopic:Cost-Benefit Analysis37) What is cost-benefit analysis? What are the steps involved in using cost-benefit analysis to make theoptimal choice?Answer:Cost-benefit analysis is a calculation that adds up the costs and benefits of a particular choiceusing a common unit of measurement. It involves the conversion of all costs and benefits to a commonunit of measurement so that they can be compared. The difference between the benefits and costs ofchoosing an alternative is referred to as the net benefit of the alternative. The alternative with the highestnet benefit is the optimal choice.Difficulty:EasyAACSB:Analytical ThinkingTopic:Cost-Benefit Analysis38) Kevin has a lot of free time, and he decides to pick up a new hobby. He has two options–he can takeart classes or sign up for cooking classes. He estimates that the art classes would cost him $70 and wouldprovide him with a benefit of $100. In contrast, the cooking classes would cost him $120 but provide himbenefits worth $160. Use cost-benefit analysis to arrive at the optimum choice for Kevin.Answer:Kevin's optimal choice depends on the net benefits of both options:Net benefit of taking art classes = $100 − $70 = $30;Net benefit of taking cooking classes = $160 − $120 = $40.Therefore, given the costs and benefits involved, Kevin should sign up for the cooking classes rather thanthe art classes.Difficulty:MediumAACSB:Application of KnowledgeTopic:Cost-Benefit Analysis

In this case, the resource istime. So, if Tom decided to work instead of spending time on Facebook, he would earn $7 every hour.Therefore, Tom's opportunity cost of spending time on Facebook is equal to $7 × 4 = $28.b) No, economic analysis does not dictate choices.Economics would not tell Tom what to do; it wouldonly help him identify the trade-offs that he is making in his decisions. Whether Tom chooses to work orspend time on Facebook is a normative choice that Tom should make based on costs and benefits.Difficulty:MediumAACSB:Application of KnowledgeTopic:Evidence-Based Economics: Is Facebook Free?1.4The Second Principle of Economics: Equilibrium1) Which of the following statements is true of equilibrium?A) Economic agents have an incentive to divert from equilibrium.B) Each economic agent can reach equilibrium irrespective of the actions of others.C) In equilibrium, the opportunity cost of the choices made by each economic agent is zero.D) In equilibrium, all economic agents are choosing the best feasible option simultaneously.Answer:DDifficulty:EasyAACSB:Analytical ThinkingTopic:The Second Principle of Economics: Equilibrium2) Which of the following will hold true if the market for cameras is in equilibrium at a price of $40?A) Sellers of cameras will have an incentive to charge a price higher than $40.B) The quantity of cameras produced will equal the quantity of cameras bought in the market.C) Buyers of cameras will want to buy fewer cameras than they are purchasing at equilibrium.D) If the cost of producing cameras falls below $40 per camera, all sellers will stop supplying cameras.Answer:BDifficulty:MediumAACSB:Application of KnowledgeTopic:The Second Principle of Economics: Equilibrium

What conditions arelikely to be satisfied in the pizza slice market?Answer:The conditions that will be satisfied when the market for pizza slices is in equilibrium are thefollowing:i) The number of pizza slices made by sellers will be equal to the number of pizza slices purchased bybuyers.ii) Pizza sellers will produce pizzas at the point where the cost of production is less than or equal to themarket price of $1.iii) Buyers will consume pizza as long as the benefit that they derive from consumption is at least equal tothe market price of $1.Difficulty:MediumAACSB:Application of KnowledgeTopic:The Second Principle of Economics: Equilibrium6) When a market is in equilibrium, both buyers and sellers do not perceive a benefit from changing theirbehavior. Why?Answer:In most economic situations, an economic agent is not optimizing individually. His decision isinfluenced by the decisions taken by other economic agents. In equilibrium, each and every economicagent is doing the best that they can do, given the information they have and given the actions of othereconomic agents. Therefore, nobody perceives a benefit from changing his or her behavior.Difficulty:EasyAACSB:Analytical ThinkingTopic:The Second Principle of Economics: Equilibrium

Empiricism isimportant, because it enables economists to determine whether economic theories are consistent withactual human behavior. This allows economists to refute faulty theories or modify them so that they are abetter fit to the real world. Empiricism also enables researchers to identify causal relationships betweendifferent sets of variables.Difficulty:EasyAACSB:Analytical ThinkingTopic:The Third Principle of Economics: Empiricism
