Scarcity is
- A.
Best measured in objective terms such as tons or kilowatt hours.
- B.
A problem only in less-developed countries
- C.
A matter of the relationship between resources and human wants
- D.
Important for microeconomics, but not macroeconomics.
Correct Answer
C. A matter of the relationship between resources and human wantsExplanation
Scarcity refers to the limited availability of resources compared to the unlimited wants and needs of individuals and society. It is a concept that applies to all countries, regardless of their level of development. Scarcity is not best measured in objective terms like tons or kilowatt hours, as it is a qualitative concept that involves the relationship between resources and human desires. Both microeconomics and macroeconomics study scarcity, as it is a fundamental concept in understanding economic behavior and decision-making at both individual and aggregate levels.Rate this question:

Karen spends $20 to hire a tutor to help her prepare for her economics final. This expense should be considered part of
- A.
The out-of-pocket cost of her college education
- B.
The opportunity cost of her college education
- C.
Both a and b
- D.
Neither a nor b
Correct Answer
C. Both a and bExplanation
The expense of hiring a tutor to help Karen prepare for her economics final should be considered part of both the out-of-pocket cost and the opportunity cost of her college education. It is an out-of-pocket cost because Karen had to spend $20 directly from her own pocket to pay for the tutor's services. Additionally, it is an opportunity cost because Karen had to forego other potential uses of that $20, such as buying study materials or participating in extracurricular activities. Therefore, the expense encompasses both the direct financial cost and the alternative opportunities she had to give up.Rate this question:

The study of the factors determining the price of gasoline relative to the price of other fuels would be primarily a concern of
- A.
Macroeconomics
- B.
Microeconomics
- C.
Normative Economics
- D.
Forecasting
Correct Answer
B. MicroeconomicsExplanation
The study of the factors determining the price of gasoline relative to the price of other fuels would be primarily a concern of microeconomics because it focuses on the individual markets and how supply and demand forces interact to determine prices. In this case, microeconomics would analyze the specific factors that affect the price of gasoline, such as production costs, consumer preferences, and competition among fuel providers. Macroeconomics, on the other hand, looks at the overall economy and broader issues like inflation and unemployment. Normative economics involves making value judgments about what the price of gasoline should be, while forecasting is the process of predicting future economic trends.Rate this question:

Policies to control unemployment are primarily a concern of
- A.
Macroeconomics
- B.
Microeconomics
- C.
Normative Economics
- D.
Econometrics
Correct Answer
A. MacroeconomicsExplanation
Macroeconomics is the study of the overall economy, including factors such as unemployment rates, inflation, and economic growth. Policies to control unemployment, which involve government intervention and macro-level strategies, fall under the purview of macroeconomics. This branch of economics focuses on understanding and analyzing the economy as a whole, rather than individual markets or specific economic agents. Therefore, it is the most appropriate field to address policies aimed at controlling unemployment at a broader level.Rate this question:

Which of the following would be most likely to cause the production possibility frontier for education and cars to shift outward?
- A.
A reduction in average hours per worker per week
- B.
An increase in the price of energy
- C.
An increase in the economy's stock of capital
- D.
None of the above
Correct Answer
C. An increase in the economy's stock of capitalExplanation
An increase in the economy's stock of capital would most likely cause the production possibility frontier for education and cars to shift outward. This is because an increase in the economy's stock of capital means that there are more resources available for production, which can lead to an increase in the production of both education and cars. With more capital, the economy can invest in better technology, machinery, and equipment, which can increase productivity and allow for the production of more goods and services. Therefore, an increase in the economy's stock of capital would result in an outward shift of the production possibility frontier.Rate this question:

The point can be produced if all factors are fully used
- B.
The point cannot possibly be produced given the current available factors of production
- C.
The point can be produced even when some of the factors are idle
- D.
No conclusion can be drawn from the information given
Correct Answer
B. The point cannot possibly be produced given the current available factors of productionExplanation
The given answer, "The point cannot possibly be produced given the current available factors of production," is the correct explanation. This means that Joe's Restaurant does not have the resources or technology to produce 500 roast turkey dinners and 600 steak dinners. The production possibility frontier represents the maximum output that can be achieved with the given resources and technology, and any point outside of this frontier is unattainable. Therefore, the point representing 500 roast turkey dinners and 600 steak dinners cannot be produced by Joe's Restaurant.Rate this question:

A rise in the price of coffee is likely to have which of the following initial effects on the market for tea, a subsitute?
- A.
A movement up along the tea demand curve
- B.
A downward movement along the tea demand curve
- C.
A leftward shift in the tea demand curve
- D.
A rightward shift in the tea demand curve
Correct Answer
B. A downward movement along the tea demand curveExplanation
A rise in the price of coffee would likely lead to a decrease in the demand for coffee, as consumers might find it more expensive and choose to buy less of it. As tea is considered a substitute for coffee, this decrease in demand for coffee would result in an increase in demand for tea. Therefore, the initial effect on the market for tea would be a downward movement along the tea demand curve, as consumers shift their preference from coffee to tea due to the increase in coffee prices.Rate this question:

An upward movement along the demand curve for cars
- B.
A downward movement along the demand curve for cars
- C.
A rightward shift in the demand curve for cars
- D.
A leftward shift in the demand curve for cars
Correct Answer
C. A rightward shift in the demand curve for carsExplanation
When consumer incomes go up, it is most likely that there will be a rightward shift in the demand curve for cars. This means that at any given price, consumers are willing and able to buy a larger quantity of cars. As their incomes increase, consumers have more purchasing power and are more likely to demand more cars. This shift indicates an increase in demand and a positive relationship between income and the quantity demanded of cars.Rate this question:

- B.
A decrease in the demand for tires
- C.
An increase in the quantity of tires demanded
- D.
A decrease in the quantity of tires demanded
Correct Answer
B. A decrease in the demand for tiresExplanation
An increase in the price of gasoline would lead to a decrease in the demand for tires. This is because gasoline and tires are considered complementary goods, meaning they are often used together. When the price of gasoline increases, it becomes more expensive to drive, leading to a decrease in the demand for cars and therefore a decrease in the demand for tires.Rate this question:

- C.
An upward movement along the shoe supply curve
- D.
A decrease int he quantity of tires demanded
Correct Answer
A. A leftward shift of the shoe supply curveExplanation
When the price of leather increases, it raises the production cost for shoe manufacturers. As a result, they are less willing or able to supply the same quantity of shoes at each price level. This leads to a leftward shift of the shoe supply curve, indicating a decrease in the quantity of shoes supplied at every price.Rate this question:

Using Qs to indicate quantity supplied and Qd to indicate quantity demanded, which of the following circumstances would be likely to produce an upward movement of the price of a good?
- A.
Qs=100, Qd=200
- B.
Qs= 100, Qd=100
- C.
Qs=200, Qd=100
- D.
Not enough information given for an answer
Correct Answer
A. Qs=100, Qd=200Explanation
When the quantity supplied (Qs) is less than the quantity demanded (Qd), it indicates that there is a shortage in the market. In this case, Qs=100 and Qd=200, which means that the demand for the good exceeds the supply. As a result, sellers can increase the price of the good to take advantage of the high demand and limited supply. This upward movement of the price is likely to occur in this circumstance.Rate this question:

An increase in the cost of raising hogs, other things being equal, would be likely to affect the price of bacon via
- A.
A leftward shift of the supply curve
- B.
A leftward shift of the demand curve
- C.
A rightward shift of the supply curve
- D.
A rightward shift of the demand curve
Correct Answer
A. A leftward shift of the supply curveExplanation
An increase in the cost of raising hogs would lead to a decrease in the supply of bacon. This is because higher costs would make it less profitable for farmers to produce bacon, resulting in a decrease in the quantity supplied at each price level. As a result, the supply curve would shift to the left, indicating a decrease in the quantity supplied at every price point. This decrease in supply would likely lead to an increase in the price of bacon, as the limited supply would not be able to meet the demand.Rate this question:

- A.
A leftward shift of the supply curve
- B.
A rightward shift of the supply curve
- C.
A movement up along the supply curve
- D.
A movement down along the supply curve
Correct Answer
C. A movement up along the supply curveExplanation
An increase in the price of beef would lead consumers to substitute beef with pork, resulting in an increase in the demand for pork. To restore equilibrium in the pork market, producers would need to respond to the increased demand by increasing the quantity supplied. This would involve a movement up along the supply curve, as producers would be willing to supply a higher quantity at each price point.Rate this question:

Suppose hot dogs to be an inferior good. An increase in consumer incomes, other things being equal, is likely to cause which of the following?
- A.
A shift in the demand curve and a higher price
- B.
A shift in the supply curve and a higher price
- C.
A shift in the demand curve and a lower price
- D.
A shift in the supply curve and a lower price
Correct Answer
C. A shift in the demand curve and a lower priceExplanation
An increase in consumer incomes would result in a shift in the demand curve for hot dogs. As hot dogs are considered an inferior good, when consumers have higher incomes, they are likely to switch to higher quality goods and decrease their demand for hot dogs. This shift in the demand curve would lead to a lower price for hot dogs as the quantity demanded decreases.Rate this question:

- A.
Shortage of steel
- B.
A decrease in the demand for steel
- C.
A decrease in the price of steel
- D.
A decrease in the quantity of steel demanded
Correct Answer
D. A decrease in the quantity of steel demandedExplanation
If the steelworkers' union negotiates a new contract with sharply higher wages, it would lead to an increase in labor costs for steel production. This increase in costs would likely result in higher prices for steel products. As a result, the quantity of steel demanded by consumers would decrease because higher prices would deter some buyers from purchasing steel. Therefore, the correct answer is a decrease in the quantity of steel demanded.Rate this question:

- A.
Meat is very expensive in cuba
- B.
Citizans are insatiable carnivores
- C.
Clerks in cuban stores work very slowly
- D.
Price of meat is held below equilibrium price
Correct Answer
D. Price of meat is held below equilibrium priceExplanation
The correct answer is that the price of meat is held below equilibrium price. This conclusion can be drawn from the observation of long lines outside every butcher shop in Havana, Cuba. If the price of meat was at equilibrium, there would not be a need for such long lines as the supply and demand would be balanced. The fact that the lines exist suggests that the price of meat is lower than what it should be in equilibrium, leading to increased demand and scarcity.Rate this question:

According to a supply and demand analysis, the likely effect of a minimum wage law would be
- A.
A shortage of jobs for low-skill workers
- B.
A shortage of workers to fill low-skill jobs
- C.
Increased incomes for all low-skill workers
- D.
Decreased incomes for all low-skill workers
Correct Answer
A. A shortage of jobs for low-skill workersExplanation
A minimum wage law would likely lead to a shortage of jobs for low-skill workers. This is because when the minimum wage is set above the equilibrium wage rate, it increases the cost of hiring low-skill workers. As a result, employers may choose to hire fewer workers or replace them with automation or other alternatives. This leads to a decrease in the quantity of low-skill jobs available, creating a shortage of jobs for these workers.Rate this question:

If the equilibrium price of sugar is 15 cents per pound and government imposes a minimum price of 20 cents per pound, the likely result will be
- A.
A shortage of sugar
- B.
A surplus of sugar
- C.
A depletion of sugar inventories
- D.
None of the above
Correct Answer
B. A surplus of sugarExplanation
If the equilibrium price of sugar is 15 cents per pound and the government imposes a minimum price of 20 cents per pound, this means that the government is setting a price floor above the equilibrium price. This will likely result in a surplus of sugar because the higher price will discourage consumers from buying as much sugar, while at the same time incentivizing producers to increase their supply. As a result, there will be more sugar supplied than demanded, leading to a surplus.Rate this question:

If a firm has total revenues of $100 million, explicit costs of $90 million, and implicit costs of $20 million, its pure economic profit is
- A.
$80 million
- B.
$70 million
- C.
$10 million
- D.
-$10 million
Correct Answer
D. -$10 millionExplanation
The firm's total revenue is $100 million, and its explicit costs are $90 million. Implicit costs are the opportunity costs of using the firm's resources, which in this case amount to $20 million. To calculate pure economic profit, we subtract both explicit and implicit costs from total revenue. Therefore, the firm's pure economic profit is -$10 million. This means that the firm is experiencing a loss of $10 million, indicating that its costs exceed its revenue.Rate this question:

Economics profit is calculated as:
- A.
Total revenue minus explicit costs minus implicit costs.
- B.
Total revenue plus explicit costs plus implicit costs.
- C.
Total revenue minus explicit costs
- D.
Total revenue minus implicit costs
Correct Answer
A. Total revenue minus explicit costs minus implicit costs.Explanation
The correct answer is "Total revenue minus explicit costs minus implicit costs." This is because economic profit takes into account not only the explicit costs (such as wages, rent, and materials) but also the implicit costs (such as the opportunity cost of the owner's time and capital). By subtracting both explicit and implicit costs from total revenue, we get a more accurate measure of the true profitability of a business or venture.Rate this question:

- A.
-$5 million
- B.
$5 million
- C.
$60 million
- D.
$65 million
Correct Answer
B. $5 millionExplanation
The pure economic profit is $5 million. This is calculated by subtracting the opportunity cost of capital from the accounting profit. The opportunity cost of capital is 12 percent of the total capital, which is $500 million x 0.12 = $60 million. Therefore, the pure economic profit is $65 million - $60 million = $5 million.Rate this question:

If a firm decided it could save on total cost by unplugging itself from the local electric utility and buying its own generating equipment, we could assume that
- A.
Both its fixed and variable costs would fall
- B.
Both its fixed and variable costs would rise
- C.
Its fixed costs would rise and its variable costs would fall
- D.
Its fixed costs would fall and its variable costs would rise
Correct Answer
C. Its fixed costs would rise and its variable costs would fallExplanation
If a firm decides to buy its own generating equipment and unplug from the local electric utility, it would incur higher fixed costs due to the initial investment and ongoing maintenance of the equipment. However, its variable costs would decrease as it would no longer need to pay for electricity from the utility. Therefore, the firm's fixed costs would rise while its variable costs would fall.Rate this question:

To attract the attention of potential customers, U.S. bank spends $500 to hire a band to play at the opening of a branch at the new Walmart shopping center. With regard to the ongoing operations of the new branch, the cost of hiring the band is considered to be
- A.
An explicit fixed cost
- B.
An implicit fixed cost
- C.
A variable cost
- D.
A sunk cost
Correct Answer
D. A sunk costExplanation
A sunk cost is a cost that has already been incurred and cannot be recovered. In this case, the bank has already spent $500 to hire the band for the opening of the branch. Once the money has been spent, it cannot be retrieved, regardless of the ongoing operations of the branch. Therefore, the cost of hiring the band is considered a sunk cost.Rate this question:

The law of diminishing returns implies that the marginal physical product curve must
- A.
Be U-shaped
- B.
Be shaped like an upside-down U
- C.
Have a negative slope throughout its length
- D.
Have a negative slope for at least part of its length
Correct Answer
D. Have a negative slope for at least part of its lengthExplanation
The law of diminishing returns states that as more units of a variable input are added to a fixed input, the marginal physical product (MPP) of the variable input will eventually decrease. This means that the additional output produced by each additional unit of the variable input will be smaller than the previous unit. Therefore, the MPP curve will have a negative slope for at least part of its length. This is because initially, as more units of the variable input are added, the MPP may increase, but eventually, due to limited resources or other factors, the MPP will start to decline.Rate this question:

The marginal curve would cut the average curve at the minimum point of the latter
- B.
The marginal curve would cut the average curve at the minimum point of the former
- C.
The marginal curve would cut the average curve at the maximum point of the latter
- D.
The marginal curve would cut the average curve at the maximum point of the former
Correct Answer
C. The marginal curve would cut the average curve at the maximum point of the latterExplanation
The marginal curve represents the additional output produced by each additional unit of input, while the average curve represents the average output per unit of input. When the marginal curve cuts the average curve, it indicates that the marginal product is equal to the average product. At the maximum point of the latter, the average product is at its highest level. Therefore, the marginal curve would cut the average curve at the maximum point of the latter.Rate this question:

The average variable cost curve must have a negative slope
- B.
The marginal cost curve must have a negative slope
- C.
The average variable cost curve must have a positive slope
- D.
The marginal cost curve must have a positive slope
Correct Answer
A. The average variable cost curve must have a negative slopeExplanation
When the marginal cost curve is below the average variable cost curve, it means that the additional cost of producing one more unit is less than the average cost of producing each unit. This suggests that the average variable cost curve must have a negative slope because the average cost is decreasing as more units are produced.Rate this question:

The quantity of output where the marginal cost curve stops decrease and begins to increase corresponds with the output where:
- A.
Average variable cost is at a maximum
- B.
Total cost is at a maximum
- C.
Marginal product of labor is at a maximum
- D.
Average product or labor is at a maximum
Correct Answer
C. Marginal product of labor is at a maximumExplanation
The correct answer is "Marginal product of labor is at a maximum." This is because the marginal cost curve represents the additional cost incurred by producing one more unit of output. When the marginal cost curve starts to increase, it indicates that the cost of producing an additional unit of output is increasing. This happens when the marginal product of labor, which measures the additional output produced by adding one more unit of labor, starts to decline. Therefore, the point where the marginal product of labor is at a maximum corresponds to the quantity of output where the marginal cost curve stops decreasing and begins to increase.Rate this question:

Rising marginal cost of production is due primarily to:
- A.
Overcrowding in the workplace
- B.
Rising fixed costs
- C.
Rising cost of inputs such as labor
- D.
Too few workers on the production line
Correct Answer
A. Overcrowding in the workplaceExplanation
The correct answer is rising fixed costs. Rising marginal cost of production occurs when the cost of producing each additional unit increases. This can be caused by various factors, but in this case, it is primarily due to rising fixed costs. Fixed costs are expenses that do not change with the level of production, such as rent, utilities, and equipment. If these costs increase, the overall cost of production increases, leading to a rise in marginal cost.Rate this question:

Which of the following statements is true of MC > ATC?
- A.
MC is falling
- B.
ATC is falling
- C.
ATC is rising
- D.
AVC is falling
Correct Answer
C. ATC is risingExplanation
When MC (Marginal Cost) is greater than ATC (Average Total Cost), it means that each additional unit produced is adding more cost than the average cost of production. This implies that the average cost of production is increasing. Therefore, the correct statement is "ATC is rising".Rate this question:

The long-run average cost curve
- A.
Passes through the minimum points of all short-run average total cost curves
- B.
Passes through the minimum points of all short-run average variable cost curves
- C.
Is the envelope of all short-run average total cost curves
- D.
Is the envelope of all short-run average variable cost curves
Correct Answer
C. Is the envelope of all short-run average total cost curvesExplanation
The long-run average cost curve is the envelope of all short-run average total cost curves because it represents the lowest possible average cost of production for each level of output in the long run. As a firm increases its scale of production and adjusts all inputs, it can take advantage of economies of scale and reduce its average costs. The envelope of all short-run average total cost curves shows the minimum average cost achievable at each level of output, which is represented by the long-run average cost curve.Rate this question:

A firm is said to experience economies of scale over the range of output for which long-run average cost
- A.
Is constant
- B.
Is falling
- C.
Is rising
- D.
Economies of scale are not related to long-run average cost
Correct Answer
B. Is fallingExplanation
When a firm experiences economies of scale, it means that as the firm increases its level of production, the average cost of producing each unit decreases. This happens because the firm can spread its fixed costs over a larger number of units, leading to lower average costs. Therefore, the correct answer is "Is falling."Rate this question:

The minimum efficient scale for a firm is the level of output at which
- A.
Economies of scale cease
- B.
Diseconomies of scale cease
- C.
Short-run average variable cost first exceeds long-run average cost
- D.
None of the above
Correct Answer
A. Economies of scale ceaseExplanation
The minimum efficient scale for a firm is the level of output at which economies of scale cease. This means that after reaching this level, the firm no longer experiences cost reductions and efficiencies associated with economies of scale. This could be due to various factors such as limited market demand, diminishing returns to scale, or increasing costs of coordination and management. At this point, the firm is producing at its most efficient level and further increases in output would result in diseconomies of scale.Rate this question:

Which of the following is a source of diseconomies of scale?
- A.
As a firm expands it's output labor begins to specialize
- B.
As a firm expands it finds itself depending more on hierarchical means of coordinating it's employees' activities
- C.
Individual employee incentives become clearer
- D.
Individual departments and divisions tend to work more as a team
Correct Answer
B. As a firm expands it finds itself depending more on hierarchical means of coordinating it's employees' activitiesExplanation
As a firm expands, it finds itself depending more on hierarchical means of coordinating its employees' activities. This is a source of diseconomies of scale because as the firm grows, the need for coordination and management increases. This can lead to increased bureaucracy, slower decision-making processes, and a loss of flexibility. The firm may also experience communication issues and difficulties in coordinating different departments and divisions, which can result in inefficiencies and higher costs.Rate this question:

Which of the following is not characteristic of perfect competition?
- A.
Many firms, each of which is small
- B.
A homogeneous product
- C.
An intense climate of rivalry among entrepreneurs
- D.
Free entry and exit
Correct Answer
C. An intense climate of rivalry among entrepreneursExplanation
Perfect competition is a market structure where there are many small firms that produce homogeneous products. In this type of market, there is intense competition among the firms, but it is not characterized by an intense climate of rivalry among entrepreneurs. Instead, perfect competition is based on the principle of price taking, where each firm is a price taker and has no control over the market price. Therefore, the absence of an intense climate of rivalry among entrepreneurs is not characteristic of perfect competition.Rate this question:

Which of the following markets can contain a number of firms producing differentiated products?
- A.
Monopoly
- B.
Monopolistic competition
- C.
Perfect competition
- D.
None of the above
Correct Answer
B. Monopolistic competitionExplanation
Monopolistic competition is the correct answer because in this market structure, there are many firms producing similar but differentiated products. Each firm has some control over the price of its product due to product differentiation, but there is still competition from other firms. Monopoly refers to a market structure with only one firm, perfect competition refers to a market with many firms producing identical products, and "none of the above" is incorrect as monopolistic competition fits the description given in the question.Rate this question:

A perfectly competitive firm sells its output for $50 a unit. At 1,000 units of output, marginal cost is $40 and is increasing, average variable cost is $35, and average total cost is $60. To maximize short-run profit, what should the firm do?
- A.
Increase output
- B.
Decrease output but not shut down
- C.
Maintain its current rate of output
- D.
Shut down
Correct Answer
A. Increase outputExplanation
To maximize short-run profit, the firm should increase output. This is because the marginal cost is less than the selling price of $50, indicating that the firm can still generate additional profit by producing more units. Additionally, the average variable cost is less than the selling price, suggesting that the firm is covering its variable costs and can benefit from economies of scale by increasing production. Therefore, increasing output would allow the firm to maximize its profit in the short run.Rate this question:

Which of the following market structures is likely to have the most barriers to entry?
- A.
Perfect competition
- B.
Monopolistic competition
- C.
Oligopoly
- D.
Monopoly
Correct Answer
D. MonopolyExplanation
A monopoly is likely to have the most barriers to entry compared to other market structures. This is because in a monopoly, there is only one firm that dominates the market and has exclusive control over the supply of a particular product or service. The barriers to entry can include high start-up costs, patents or copyrights, government regulations, and economies of scale that make it difficult for new firms to enter the market and compete effectively. As a result, monopolies often have little or no competition, allowing them to set higher prices and earn higher profits.Rate this question:

A perfectly competitive firm sells its output at $40 per unit. At 100 units of output, it has an average total cost of $40. Marginal cost is equal to average total cost at that point. To maximize profit, what should the firm do?
- A.
Increase output
- B.
Decrease output
- C.
Maintain its current rate of output
- D.
Insufficient information is given for an answer to be reached.
Correct Answer
C. Maintain its current rate of outputExplanation
The firm should maintain its current rate of output because when the marginal cost is equal to the average total cost, the firm is already producing at the most efficient level. Increasing or decreasing output would result in either higher costs or lower revenues, leading to a decrease in profit. Therefore, the firm should continue producing at the current rate to maximize its profit.Rate this question:
