Assume that hamburgers and ketchup are complements. If the price of hamburgers falls, demand for ketchup:
increases As the price of hamburgers falls, people will consume more hamburgers. (Quantity demanded increases, causing movement along the demand curve.) As a result, people will also consume more of the complementary good (consumed together), ketchup. (An increase in demand shifts the curve to the right.)
The fundamental reason why supply curves slope upward is:
increasing costs

Why might an airline company (assuming it is a monopoly) charge different fares to different groups of customers?
Airlines charge different fares to different groups of customers in order to maximize the revenue (and therefore profit) generated from a given flight. By imposing restrictions such as advance purchase and minimum stay, the airline can discriminate between business travelers (who have a higher willingness to pay) and nonbusiness travelers (who have a lower willingness to pay). Fares are set accordingly. This helps the company realize more revenue than would have been generated if all consumers paid the same price.
diminishing marginal returns
An additional worker adds to total output, but at a diminishing rate.
How might the market imbalances caused by an anti-price gouging law be dealt with?
Anti-price gouging laws cause an insufficient supply (shortage) in the market. (Such laws are frequently imposed in the case of natural disasters when the markets are disrupted by the disaster.) Providing incentives for firms to increase supply can reduce this shortage. Such incentives could include subsidies or tax breaks designed to offset higher costs associated with increasing supply in a disaster ravaged area. Another approach might be to segment the market by capping the price of existing supplies in the market, and allowing higher prices to be charged for new supplies.

How do barriers to entry benefit a monopoly?
Barriers to entry include control over inputs, economies of scale and government protection in the form of patents and copyrights. Each of these deters new companies from competing with the monopolist.

An agreement between firms (or countries) in an industry to formally collude on price and output, then agree on the distribution of production.
Explain how an effective (binding) price ceiling can incur costs and benefits for an economy.
An effective price ceiling caps the price below the free market equilibrium price. This results in a shortage, an imbalance between the market's quantity demanded and quantity supplied. Consequently, some consumers will be able to buy the product at a below equilibrium price (benefits), and other willing buyers will not have access to the product because of insufficient quantity supplied at that price (costs).
network externality
An external benefit generated from the consumption of a network good.
free rider
An individual who avoids paying for a good because he or she cannot be excluded from enjoying the good once provided.
Willingness-to-pay
An individual's valuation of a good or service, equal to the most an individual is willing and able to pay.
natural monopoly
An industry exhibiting large economies of scale such that the minimum efficient scale of operations is roughly equal to market demand.
increasing cost industry
An industry that, in the long run, faces higher prices and costs as industry output expands. Industry expansion puts upward pressure on resources (inputs), causing higher costs in the long run.
decreasing cost industry
An industry that, in the long run, faces lower prices and costs as industry output expands. Some industries enjoy economies of scale as they expand in the long run, typically the result of technological advances.
constant cost industry
An industry that, in the long run, faces roughly the same prices and costs as industry output expands. Some industries can virtually clone their operations in other areas without putting undue pressure on resource prices, resulting in constant operating costs as they expand in the long run.
essential facility
An input that is needed to produce a product or to allow a person to consume a product.
kinked demand curve
An oligopoly model that assumes that if a firm raises its price, competitors will not raise theirs. However, if the firm lowers its price, its competitors will lower their price to match the reduction. This leads to a kink in the demand curve and relatively stable market prices.
Nash equilibrium
An outcome that occurs when all players choose their optimal strategy in response to all other players' potential moves. At a Nash equilibrium, no player can be better off by unilaterally deviating from the noncooperative outcome.
Explain the difference between output combinations that lie inside the PPF and those that lie outside the PPF.
An output combination that lies inside a PPF indicates that the economy is not using all of its inputs to produce goods and services. An output combination that lies outside the PPF is impossible because the economy has insufficient resources to produce at these levels.
barriers to entry
Any obstacle that makes it more difficult for a firm to enter an industry, and includes control of a key resource, prohibitive fixed costs, and government protection.
economies of scale
As a firm's output increases, its LRATC tends to decline. This results from specialization of labor and management, and potentially a better use of capital and complementary production techniques.
An economy is recovering from recession; short-run economic growth is occurring. What happens to the economy's inputs during the recovery and how is this presented on a PPF?
As an economy is recovering, previously idle or underutilized resources become active and begin contributing to economic output. Examples of this phenomenon include unemployed people returning to work, empty stores becoming utilized, and previously idle factories again producing products. This is represented on a PPF by movement from a point inside the PPF to a point closer to or on the PPF.
law of diminishing marginal utility
As we consume more of a given product, the added satisfaction we get from consuming an additional unit declines.
How can a repeated game help in resolving a prisoner's dilemma outcome?
Assume two companies (A and B) are engaged in a repeated game, and both are making decisions that result in the highest collective profit. Company A decides on an action designed to maximize its profit at the expense of company B. The next time the game is played, company B can decide to match company A's action which results in a prisoner's dilemma outcome, and denies company A the benefits of its noncooperative strategy, a tit-for-tat strategy. When company B does this, it is signaling to company A that it won't allow company A to gain at its expense. Hence, company A's best strategy when the game is played the next time is to cooperate and allow for the maximization of joint profits.
Ceteris Paribus
Assumption used in economics (and other disciplines as well), where other relevant factors or variables are held constant.
teaser strategies
Attractive up-front deals used as an incentive to entice new customers into a network.
Consider the market for printed textbooks. Which of the following will cause lower prices and a lower quantity of printed textbooks exchanged? A. There is a doubling of the number of college students living in the area. B. There is increased availability of electronic textbooks viewable on iPads and tablet computers. C. Technological improvements lower the costs of printing books. D. A fire destroys half the inventory of printing paper
B
Explain the importance of the absence of barriers to entry in perfectly competitive markets to long-run pricing in these markets.
Because perfectly competitive markets have no barriers to entry, when existing firms in the market realize positive economic profits in the short run, firms outside the industry are attracted to the profit opportunity and choose to enter the market in the long run. This entry causes an increase in the market's supply; the increase in supply reduces the market equilibrium price, eliminating the short-run profits.
What best describes the difference between public television and on-demand cable television?
Both are nonrival but public television is nonexclusive
market structure analysis
By observing a few industry characteristics such as number of firms in the industry or the level of barriers to entry, economists can use this information to predict pricing and output behavior of the firm in the industry.
economies of scope
By producing a number of products that are interdependent, firms are able to produce and market these goods at lower costs.
Consider the market for athletic apparel. Which of the following will cause lower prices and a greater quantity of athletic apparel and equipment exchanged? A. New medical studies demonstrate positive health benefits from regular exercise. B. There is a significant decrease in the price of jeans and sweaters. C. There is a reduction in the cost of cotton, synthetic fibers and other clothing inputs. D. The government places a tax on the sale of clothing.
C
A budget line represents the: A. aggregate spending by the federal government given product prices B. combinations of goods than an economy can produce utilizing all available resources C. combinations of goods an individual can purchase given product prices and available income D. opportunity costs an economy incurs as more of one good and less of another good is produced
C The budget line shows all of the combinations of two goods a consumer can afford given his or her available income.
Which of the following statements is true of incentives? A. People respond to financial incentives only. B. People respond to good incentives but ignore bad incentives. C. Rules can be established to prevent people from acting on certain incentives. D. Stealing is an outcome of a response to a good incentive.
C; People are motivated to achieve the benefits of a good incentive and avoid the negative consequence of a bad incentive.
Which of these is NOT an example of market failure? Competition leads firms to provide products at the lowest possible price. Water is polluted by a paper company located by a river. Air is polluted by a manufacturing firm. Consumers must buy water from one local water utility.
Competition leads firms to provide products at the lowest possible price.
One of the determinants of the price elasticity of demand is time. If gasoline prices increase substantially, what adjustments might consumers make over the long run that would increase their responsiveness to changes in the price of gasoline?
Consumers have very little ability to respond to a gasoline price increase in the short run. While they may be able to cut down on driving slightly, their day-to-day life, driving to work, school, and so on, will continue, with the consumption of gas remaining about the same. This means that the responsiveness of consumers to the price change is relatively low. A low responsiveness results in the price increase being greater than the reduction in quantity demanded Consequently, in the short run, the price elasticity of demand is less than one or inelastic. Over the long run, consumers can buy more fuel efficient cars, move closer to work, or start using mass transit. These actions will reduce fuel consumption and increase consumers' responsiveness to changes in the price of gasoline. Therefore, demand for gasoline may become price elastic in the long run.
Why might a business choose to emit pollution?
Controlling pollution frequently requires a firm to invest in new and possibly higher cost technology to achieve the desired pollution reductions. These higher costs might cause the firm's overall production costs to increase. With higher costs, the firm might have difficulty in matching the prices of firms that didn't make pollution control investments. Thus, the firm might not earn acceptable profits.
Consider the market for whole wheat bread. Which of the following will cause higher prices and a lower quantity of whole wheat bread exchanged? A. Scientists discover new health benefits of eating whole wheat products. B. The price of white bread declines significantly. C. Union concessions result in lower labor costs of bakers and other bakery workers. D. Flour mills increase the cost of whole wheat flour purchased by bread bakeries.
D
Which of the following is the best example of substitutes? A. money and donuts B. chips and salsa C. macaroni and cheese D. hiking boots and athletic shoes E. DVD players and DVDs
D
Which statement is not correct? A. The sum of consumer and producer surplus increases as markets become more efficient. B. A reduction in total consumer and producer surplus indicates markets have become less efficient. C. When prices are below market equilibrium, the sum of consumer and producer surplus decreases. D. When prices are above market equilibrium, the sum of consumer and producer surplus increases. E. All are correct
D
Which of the following statements is true of markets? A. Government intervention in markets should always be avoided. B. There are no disadvantages of having free markets. C. Markets discourage competition among firms. D. Free markets sometimes fail to produce best results for society, but such failure can be reduced by government intervention.
D; Because free markets are based on maximizing the benefits of a transaction for the transaction's participants, they sometimes result in outcomes that are inefficient for society. Government intervention can reduce (or eliminate) this inefficiency.
Which response is expected in the milk market if the price of chocolate chip cookies declines? Demand increases; quantity exchanged increases; and price increases. Demand increases; quantity exchanged increases; and price decreases. Demand decreases; quantity exchanged decreases; and price increases. Demand decreases; quantity exchanged decreases; and price decreases. Not enough information is given to answer the question.
Demand increases; quantity exchanged increases; and price increases.
Entrepreneurs
Entrepreneurs combine land, labor, and capital to produce goods and services. They absorb the risk of being in business, including the risk of bankruptcy and other liabilities associated with doing business. Entrepreneurs receive profits for their effort.
command and control policies
Environmental policies that set standards and issue regulations, which are then enforced by the legal and regulatory system.
market-based policies
Environmental policies that use charges, taxes, subsidies, deposit-refund systems, or tradable emission permits to achieve environmental goals.
profit
Equal to the difference between total revenue and total cost.

Equal to total cost divided by output (TC/Q). Average total cost is also equal to AFC + AVC.
(T/F) An increase in the price of milk will cause a decrease in the demand for milk.
False
(T/F) An increase in the price of milk will cause an increase in the supply of ice cream.
False
(T/F) If your friend offers to drive you to the store so you don't have to drive your own car, then your opportunity cost of going to the store is zero
False
A decrease in the price of milk will cause an increase in the demand for milk.
False
A surplus would result from either a decrease in supply or an increase in demand.
False
One of the costs of a minimum wage is that it creates a shortage of workers.
False
(T/F) A perfectively competitive industry's market demand curve is a horizontal line.
False Although a firm in perfect competition faces a horizontal demand curve because each firm takes the equilibrium price as given, the market itself (representing the demand faced by all the producers in the market) has a downward sloping to the right of the demand curve.
If the price of a resource required to produce a good increases, the supply curve will shift to the right, indicating that producers are inclined to produce more of the good at each price point.
False As the price of production inputs increases, firms' profit opportunities per unit are decreased. Consequently, firms will produce less at each price point. This is represented by a leftward shift of the supply curve.
(T/F) Prisoner's dilemma outcomes are uncommon.
False Because prisoner's dilemma games occur in competitive (vs. cooperative) situations, and competitions are frequent in the business, political, legal, and sports worlds, among many others, these outcomes are frequent.
In an economy producing just beer and autos, producing increasing amounts of autos requires giving up decreasing amounts of beer.
False Because the resources initially transferred from beer production to auto production would be those least suited to beer production, the initial reduction in beer production would be relatively small. Further increasing auto production would require transferring resources better suited to beer production and result in a larger reduction in beer production. This is an illustration of diminishing returns to inputs.
(T/F) When a business sells an excess factory, it is incurring a sunk cost
False Because this business is recovering at least a portion of its fixed costs by selling the factory, the fixed costs associated with the factory are not a sunk cost. Sunk costs are not recoverable.
(T/F) If a business has revenue of $100,000, explicit costs of $50,000, and implicit costs of $60,000, it is earning an economic profit.
False Economic profit includes both implicit and explicit costs.
(T/F) Goods generating positive externalities are over-produced or over-consumed.
False Goods generating positive externalities are under-consumed and or under-produced because the private parties in a transaction are only interested in maximizing their own well-being and do not include the larger benefits to society in their decision making. As a result, less than a socially optimal quantity of the good is produced and consumed or produced.
(T/F) All monopolies earn profits.
False Just like any business, a monopoly can be unsuccessful in the sense that it loses money even though the firm has market power with respect to setting prices and the level of output. If the firm is the only producer of a product, but the product doesn't meet consumer needs and expectations, the firm will fail.
(T/F) Public goods are both rival and excludable
False Public goods are nonrival and nonexcludable. Nonrival means that one person's consumption of the good does not diminish another person's enjoyment of the good. Nonexcludable means that no one can be excluded from consuming the good, even if they don't pay for the good.
The price elasticity of supply measures the relationship between changes in quantity demanded of a good and changes in its quantity supplied.
False The price elasticity of supply measures the responsiveness of the quantity supplied of a good to changes in the price of the good.
(T/F) A firm in a perfectly competitive market maximizes its profits when its marginal cost equals its total revenue.
False The profit-maximizing output level for a firm in perfect competition is where the firm's marginal cost equals its marginal revenue. If the firm were to select another output level (higher or lower) it would earn less profit.
(T/F) A Nash equilibrium always yields the best outcome for all participants in a game
False There are many instances when a Nash equilibrium can result in a less than the best outcome for participants. When participants are competitive (as opposed to cooperating), a Nash equilibrium results in a less favorable, joint outcome for all the participants.
If a price floor is effective, all suppliers benefit from equilibrium prices below the free market prices
False To be effective a price floor must be placed above the free market equilibrium price and not below.
(T/F) A profit-maximizing monopolist can charge any price to consumers.
False To maximize profits, the monopolist's pricing is constrained by the price indicated by the demand curve for the level of output selected. If the monopoly were to charge a higher price than indicated by the demand curve, it would lose profit generating customers.
Price controls provide only benefits but no costs to society.
False While often price controls benefit a segment of society; this type of government intervention has a tradeoff involving costs. For example, anti-price gouging laws keep prices under control; however, supply is insufficient to meet the needs of all consumers.
Combinations of output that lie on the PPF are inefficient.
False Combinations of output that lie on the PPF require the economy to use all of its available resources at maximum productivity. This is considered an efficient output level.
A country that is normally strong in human capital has a weak educational system.
False; A strong educational system that helps develop valuable skills in the population, and exposes people to a diverse ideas is an important ingredient in fostering human creativity.
Thinking at the margin means that decision makers think about all costs associated with an action, both those that may change as a result of a decision and those that won't change.
False; Marginal thinking requires consideration of just those costs and benefits that change as a result of the decision under review.
Fat's Meats is part of the cartel that controls the kielbasa industry. Which of the following would cause instability in this cartel?
Fat's Meats could cheat and sell more kielbasa than it agreed to. Cartels are inherently unstable because of the incentive to cheat by individual firms that wish to increase their earnings.
Five Steps to Maximizing Profits in a Competitive Market
Find MR = MC. Find optimal quantity where MR = MC. Find optimal price. (Hint: It's already given!) Find the average total cost at the optimal Q. Find the profit = (P − ATC) × Q.
What is required for an economy to experience long-run growth and how would this growth be captured on a PPF?
For an economy to grow in the long-run, it must increase its capability to produce goods and services. Such an expansion can be achieved by expanding the inputs available to the economy and/or by deploying technology that enable producing more output with existing inputs. Economic growth is depicted on a PPF as a movement of the PPF curve away from the origin.
Why is game theory important to economics?
Game theory is the study of how businesses and individuals interact with one another to achieve their goals. It helps us understand and predict behavior by participants in some economic decisions. Hence, it is an important tool for economists.
sequential-move games
Games in which players make moves one at a time, allowing players to view the progression of the game and to make decisions based on previous moves.
simultaneous-move games
Games in which players' actions occur at the same time, forcing players to make decisions without knowing how the other players will act. These games are analyzed using diagrams called game tables.
Production efficiency
Goods and services are produced at their lowest resource (opportunity) cost.
Substitutes
Goods consumers substitute for one another depending on their relative prices, such as coffee and tea. Substitutes have a positive cross elasticity of demand.
Substitute goods
Goods consumers will substitute for one another. When the price of one good rises, the demand for the other good increases, and vice versa.
Complements
Goods that are typically consumed together, such as coffee and sugar. Complements have a negative cross elasticity of demand.
Complementary goods
Goods that are typically consumed together. When the price of a complementary good rises, the demand for the other good declines, and vice versa.
Luxury goods
Goods that have income elasticities greater than 1. When consumer income grows, demand for luxury goods rises more than the rise in income.
Inferior goods
Goods that have income elasticities that are negative. When consumer income grows, demand for inferior goods falls.
Normal goods
Goods that have positive income elasticities less than 1. When consumer income grows, demand for normal goods rises, but less than the rise in income.
public goods
Goods whose consumption by one person cannot diminish the benefit to others of consuming the good (i.e., nonrivalry), and once they are provided, no one person can be excluded from consuming (i.e., nonexclusion).
Law of demand
Holding all other relevant factors constant, as price increases, quantity demanded falls, and as price decreases, quantity demanded rises.
Law of supply
Holding all other relevant factors constant, as price increases, quantity supplied rises and as price declines, quantity supplied falls.
Which is NOT considered a basic economic question? How will the system accommodate change? Who will receive the goods and services? What goods and services will be produced? How will these goods and services be produced?
How will the system accommodate change?
Which situation(s) may require government intervention? I. A local business has made a profit in each of the last ten years. II. Students are having difficulty deciding whether to go the beach or to go hiking for their class trip. III. A manufacturing firm on a river is dumping production run off into the water.
III only
How does knowledge of price elasticity of demand for a firm's products help a firm make decisions regarding price increases?
If a firm is considering a price increase, it would be interested in understanding the impact of the price increase on its revenue. If a firm knows that the demand for its product is price inelastic, it can conclude that the percentage change in the quantity demanded of its product will be less than the percentage change in its price. Hence, in such cases, an increase in the price of the product will lead to an increase in the revenue of the firm.
Coase theorem
If transaction costs are minimal (near zero), a bargain struck between beneficiaries and victims of externalities will be efficient from a resource allocation perspective. As a result, a socially optimal level of production will be reached.
Some experts suggest that if there were no immigration, the United States population would not be growing. The average age in the United States is increasing. What is the likely effect of increased immigration and an aging population on society's income distribution? Immigration and the aging of the population both tend to decrease average household income. Immigration will tend to decrease household income in the short run, while the aging of the population will tend to increase it; the net effect is an increase. Immigration will tend to increase household income in the short run, while the aging of the population will tend to decrease it; the net effect is a decrease. The two trends will offset each other, leaving the distribution of income unchanged.
Immigration and the aging of the population both tend to decrease average household income.
long-run average total cost
In the long run, firms can adjust their plant sizes so that LRATC is the lowest unit cost at which any particular output can be produced in the long run.
Labor
Includes the mental and physical talents of individuals who produce products and services. The payment to labor is wages.
poverty thresholds
Income levels for various household sizes, below which people are considered to be living in poverty.
price taker
Individual firms in perfectly competitive markets determine their prices from the market because they are so small they cannot influence market price. For this reason, perfectly competitive firms are price takers and can sell all the output they produce at market-determined prices.
The United States has an absolute advantage in making short-sleeve cotton golf shirts. Why do Indonesia and Bangladesh make these shirts and export them to the United States?
Indonesia and Bangladesh have a lower opportunity cost of producing the shirts than the United States. A country would produce the good if it has a lower opportunity cost of producing the good than the other country. Indonesia and Bangladesh, while smaller, have a comparative advantage in the production of shirts, making it profitable for both countries to specialize and ship shirts to the United States.
In May 2011, Brazil announced a large discovery of oil in its deep-water fields. Estimated at 4.5 billion barrels, it was the largest discovery for Brazil in nearly three years. How is this discovery likely to affect OPEC?
It makes Brazil a stronger competitor. Brazil is not (at this writing) a member of OPEC. The discovery boosts Brazil as an oil producer and exporter, which is a challenge to OPEC's market power.
Which statement illustrates the law of demand? Lindsay offers to buy more sticks of chewing gum at $2 than at $1. Lindsay offers to buy more sticks of chewing gum at $1 than at $2. Marcus offers to sell more sticks of chewing gum at $2 than at $1. Marcus offers to sell more sticks of chewing gum at $1 than at $2.
Lindsay offers to buy more sticks of chewing gum at $1 than at $2.
Among perfectly competitive firms, profit maximizing will always operate where:
MC = MR
An unregulated natural monopolist would produce to the point at which:
MR = MC
Equilibrium
Market forces are in balance when the quantities demanded by consumers just equal the quantities supplied by producers.
price caps
Maximum price at which a regulated firm can sell its product. They are often flexible enough to allow for changing cost conditions.
Do the equilibrium price and quantity always move in the same direction when there is a change in demand or supply?
No, the equilibrium price and quantity do not always move in the same direction when there is a change in demand or supply. When demand increases or decreases, equilibrium price and quantity do move in the same direction. When supply increases, equilibrium price decreases and quantity increases. When supply decreases, equilibrium price increases while quantity decreases. When both the supply and demand curves shift, the equilibrium quantity will rise. However, the equilibrium price will depend on the relative magnitude of the supply and demand shifts.
Are all fixed costs sunk costs? Explain.
No. Fixed costs do not change in the short run as the level of output in the firm changes. Sunk costs are fixed costs that once spent cannot be recovered in whole or part. For example, college tuition (a fixed cost, since it doesn't vary no matter how much one studies) is a sunk cost; once spent, it cannot be transferred to benefit another student or (after add/drop) refunded. A physical textbook (a fixed cost, since its cost doesn't vary whether one reads it or not) is not a sunk cost: typically it can be sold on the used book market to recover at least part of the purchase price.
Determinants of supply
Nonprice factors that affect supply, including production technology, costs of resources, prices of related commodities, expectations, number of sellers, and taxes and subsidies.
Change in demand
Occurs when one or more of the determinants of demand changes, shown as a shift in the entire demand curve.

Occurs when people make decisions based on how much was already spent, rather than how the decision might affect their current well-being.
Surplus
Occurs when the price is above market equilibrium, and quantity supplied exceeds quantity demanded.
Shortage
Occurs when the price is below market equilibrium, and quantity demanded exceeds quantity supplied.
Change in quantity demanded
Occurs when the price of the product changes, shown as a movement along an existing demand curve.
Change in quantity supplied
Occurs when the price of the product changes, shown as a movement along an existing supply curve.
What circumstance might lead a firm in a perfectly competitive market to realize a positive, short-run, economic profit?
Once a firm has selected its profit-maximizing output level (where marginal revenue equals marginal cost), the optimal output level for the firm is known. At this output level, the firm can determine its average total cost per unit. If the market price per unit is above the average total cost per unit (which includes all the firm's opportunity costs), the firm is earning a positive short-run economic profit.
nonexcludability
Once a good or service is provided, it is not possible to exclude others from enjoying that good or service.
Comparative advantage
One country has a lower opportunity cost of producing a good than another country.
product differentiation
One firm's product is distinguished from another's through advertising, innovation, location, and so on.
rate of return regulation
Permits product pricing that allows the firm to earn a normal return on capital invested in the firm.
trembling hand trigger
Players forgive certain instances of defection as "mistakes" before retaliation is taken
Unitary elastic supply
Price elasticity of supply is equal to 1. The percentage change in quantity supplied is equal to the percentage change in price.
Elastic supply
Price elasticity of supply is greater than 1. The percentage change in quantity supplied is greater than the percentage change in price.
Inelastic supply
Price elasticity of supply is less than 1. The percentage change in quantity supplied is less than the percentage change in price.
Consider the market for hamburgers. Which of the following will cause lower prices and a greater quantity of hamburgers exchanged? There is a doubling of the number of college students living in the area. Local pizza restaurants lower their prices and begin campus delivery services. Prices decline for hamburger buns, lettuce, tomato and cheese. A disease wipes out half of the livestock in the United States supplying beef to restaurants. None of the above
Prices decline for hamburger buns, lettuce, tomato and cheese.
Why are public goods usually provided by the government?
Private markets have difficulty earning profits from the production of many public goods. This is because these goods are both nonrival and nonexcludable. Examples are national defense, public safety, and clean air. In the absence of a profit opportunity, private industry will not produce a good, but in response to the presence of public need for such socially desirable goods, the government can (as a result of its ability to tax) step in to produce these goods.
Resources
Productive resources include land (land and natural resources), labor (mental and physical talents of people), capital (manufactured products used to produce other products), and entrepreneurial ability (the combining of the other factors to produce products and assume the risk of the business).
x-inefficiency
Protected from competitive pressures, monopolies do not have to act efficiently. Examples include spending on corporate jets, lavish travel, and other nonessential perks.
Incidence of taxation
Refers to who bears the economic burden of a tax. The economic entity bearing the burden of a particular tax will depend on the price elasticities of demand and supply.
marginal cost pricing rule
Regulators would prefer to have natural monopolists price where P = MC, but this would result in losses (long term) because ATC > MC.
average cost pricing rule
Requires a regulated monopolist to produce and sell output where price equals average total cost. This permits the regulated monopolist to earn a normal return on investment over the long term and therefore remain in business.
rent seeking
Resources expended to protect a monopoly position. These are used for such activities as lobbying, extending patents, and restricting the number of licenses permitted.
"tragedy of the commons"
Resources that are owned by the community at large (e.g., parks, ocean fish, and the atmosphere) therefore tend to be overexploited because individuals have little incentive to use them in a sustainable fashion.
If Rosco's Tacos competes with eight other fast-food restaurants in the same neighborhood, and two of those rival firms exit the market, then: the market supply curve will shift to the right. the market demand curve will shift to the left. Rosco's supply curve will shift to the right. Rosco's demand curve will shift to the right.
Rosco's demand curve will shift to the right
Production possibilities frontier (PPF)
Shows the combinations of two goods that are possible for a society to produce at full employment. Points on or inside the PPF are attainable, and those outside of the frontier are unattainable.
partnership
Similar to a sole proprietorship, but involves more than one owner who share the management of the business. Partnerships are also subject to unlimited liability.
How is the concept of cross price elasticity of demand relevant for a business owner?
Since cross price elasticity measures the responsiveness of quantity demanded of one good to changes in the price of another good, a business owner can use this knowledge to anticipate changes in the demand for his products in response to changes in the price of other goods. For example, ketchup and hamburgers are complements so cross elasticity of demand is negative. If the price of beef goes up, say due to a drought, the price of hamburgers will also go up, and people will consume less of them. As a result, people would also buy less ketchup. Hence, the ketchup producer should plan to produce less when he/she expects beef prices to rise.
Why is the marginal revenue of a firm in perfect competition equal to the market price?
Since there are many small firms in a perfectly competitive market, the quantity produced by any one firm is a very small percent of the market's overall output. This means the individual firm's output decisions have no meaningful effect on the market's overall output level or the market price. Consequently, the additional revenue (marginal revenue) gained by the firm as it increases output is equal to the market price.
What might be done with the surplus caused by a government agricultural price support program?
Some of the surplus might be used for school lunches and in other government institutions; other parts of the surplus might be destroyed. When a government price support (price floor) is set above the equilibrium price for the commodity, it causes a surplus. The surplus is frequently purchased by the government so that the excess does not enter the market depressing market prices below the desired level.
marginal product
The change in output that results from a change in labor (ΔQ/ΔL).
marginal revenue
The change in total revenue from selling an additional unit of output. Because competitive firms are price takers, P = MR for competitive firms.
Provide an example of a third party benefiting from a prisoner's dilemma outcome while the game participants are worse off relative to other possible outcomes. Also, explain the nature of the benefit.
The customers (the third parties in this instance) of competing companies engaged in a game with a prisoner's dilemma might benefit from lower prices for both companies' goods and services as the companies are likely to engage in vigorous price competition.
If bagels and doughnuts are substitute goods, then which scenario is likely to occur if the price of bagels is reduced?
The demand curve for doughnuts will shift to the left.

income deficit
The difference between the poverty threshold and a family's income.
accounting profit
The difference between total revenue and explicit costs. These are the profits that are taxed by the government
Consumer surplus
The difference between what consumers (as individuals or the market) would be willing to pay and the market price. It is equal to the area above market price and below the demand curve.
functional distribution of income
The distribution of income for resources or factors of production (land, labor, capital, and entrepreneurial ability).
The United Nations reports data on income distribution for different countries as a ratio of the income of the richest 10% to the income of the poorest 10%. If the ratio for Japan is 4.5 and the ratio for the United States is 15.9, which of the following statements is correct? The distribution of income is more equal in Japan This is the same thing as the Gini coefficient The ratio is the slope of the Lorenz curve for each country The distribution of income is more equal in the united states

Please choose the correct answer from the following choices, and then select the submit answer button. The distribution of income is more equal in Japan.
Simon likes to smoke cigars on his porch during the day on weekends. But his neighbor, Frank, can't stand the smell so he avoids grilling while Simon is outside. What is the origin and who is affected by this externality?
The externality originates from a consumer and the impact is taken by a consumer.
Incentives
The factors that motivate individuals and firms to make decisions in their best interest.
Markets
The institutions that bring together buyers and sellers, so that they can interact and transact with each other.
Demand
The maximum amount of a product that buyers are willing and able to purchase over some time period at various prices, holding all other relevant factors constant (the ceteris paribus condition).
Supply
The maximum amount of a product that sellers are willing and able to provide for sale over some time period at various prices, holding all other relevant factors constant (the ceteris paribus condition).
Allocative efficiency
The mix of goods and services produced is just what the society desires.
What should be included in determining the opportunity cost of an action?
The opportunity cost of an action is the value of the next best option that is not selected as a result of the option that is selected. In assessing this value, the costs and benefits of the option should include all the benefits and costs of the action not selected, both financial and nonfinancial.
implicit costs
The opportunity costs of using resources that belong to the firm, including depreciation, depletion of business assets, and the opportunity cost of the firm's capital employed in the business.
Elastic demand
The percentage change in quantity demanded is greater than the percentage change in price. This results in the absolute value of the price elasticity of demand to be greater than 1. Goods with elastic demands are very responsive to changes in price.
Unitary elastic demand
The percentage change in quantity demanded is just equal to the percentage change in price. This results in the absolute value of the price elasticity of demand to be equal to 1.
Inelastic demand
The percentage change in quantity demanded is less than the percentage change in price. This results in the absolute value of the price elasticity of demand to be less than 1. Goods with inelastic demands are not very responsive to changes in price.
poverty rate
The percentage of the population living in poverty.
interconnection
The physical linking of a network to another network's essential facilities. Interconnection promotes competition by ensuring that no firm has exclusive access to a set of customers.
virtuous cycle
The point at which a network good reaches its tipping point, when network effects cause demand for the good to increase on its own. As more people buy or subscribe to a good or service, it generates even more external benefits and more demand.
Horizontal summation
The process of adding the number of units of the product purchased or supplied at each price to determine market demand or supply.
Production
The process of converting resources (factors of production)—land, labor, capital, and entrepreneurial ability—into goods and services.
How would a business owner use information about marginal revenue versus marginal cost and price versus average total cost?
The profit maximizing rule (marginal revenue equal to marginal cost) tells the business owner the level of output and price that will maximize the firm's profits, though not its level of profits (or losses). Price less average total cost indicates to the business owner the level of profit (or loss) per unit of output the firm is realizing.
tipping point (or critical mass)
The quantity from which network effects are strong enough to support the network.
rate of income to poverty
The ratio of family income to the poverty threshold. Families with ratios below 0.5 are considered severely poor, families with ratios between 0.5 and 1.0 are considered poor, and those families with ratios between 1.0 and 1.25 are considered near poor.
Deadweight loss
The reduction in total surplus that results from the inefficiency of a market not in equilibrium.
government failure
The result when the incentives of politicians and government bureaucrats do not align with the public interest.
normal profits
The return on capital necessary to keep investors satisfied and keep capital in the business over the long run.
behavioral economics
The study of how human psychology enters into economic behavior as a way to explain why individuals sometimes act in predictable ways counter to economic models.
game theory
The study of how individuals and firms make strategic decisions to achieve their goals when other parties or factors can influence that outcome.
Economics
The study of how individuals, firms, and society make decisions to allocate limited resources to many competing wants.
Macroeconomics
The study of the broader issues in the economy such as inflation, unemployment, and national output of goods and services.
Microeconomics
The study of the decision making by individuals, businesses, and industries.
total cost
The sum of all costs to run a business. To an economist, this includes out-of-pocket expenses and opportunity costs.
Total surplus
The sum of consumer surplus and producer surplus, and a measure of the overall net benefit gained from a market transaction.
economic costs
The sum of explicit (out-of-pocket) and implicit (opportunity) costs.
Long run
The time period long enough for firms to alter their plant capacities and for the number of firms in the industry to change. Existing firms can expand or build new plants, or firms can enter or exit the industry.
Market period
The time period so short that the output and the number of firms are fixed. Agricultural products at harvest time face market periods. Products that unexpectedly become instant hits face market periods (there is a lag between when the firm realizes it has a hit on its hands and when inventory can be replaced).
Short run
The time period when plant capacity and the number of firms in the industry cannot change. Firms can employ more people, have existing employees work overtime, or hire part-time employees to produce more, but this is done in an existing plant.
total utility
The total satisfaction that a person receives from consuming a given amount of goods and services.
What is the utility maximization rule?
The utility maximization rule states total utility is maximized when the marginal utility per dollar for the last unit of each good consumed is equal. Utility is the satisfaction or well-being a consumer enjoys from consuming a good. Marginal utility is the additional satisfaction from consuming an additional unit of a good. When the utility maximization condition is not met, consumers can improve their total utility by reallocating their spending until the condition is met.
Opportunity cost
The value of the next best alternative; what you give up to do something or purchase something.
Which statement is TRUE about specialization and exchange between two individuals? They generally benefit the richer individual at the expense of the poorer individual. They generally benefit the poorer individual as well as the richer individual. They generally benefit the poorer individual at the expense of the richer individual. They generally benefit neither the poorer individual nor the richer individual.
They generally benefit the poorer individual as well as the richer individual.
Which of the following is NOT a reason why standards for reducing pollution are popular? They are cheaper than market-based policies. They prevent competing firms from polluting. They lead each firm to have the same abatement costs. They are simple.
They lead each firm to have the same abatement costs.
sunk costs
Those costs that have been incurred and cannot be recovered.
explicit costs
Those expenses paid directly to another economic entity, including wages, lease payments, taxes, and utilities.
utility-maximizing rule
Total utility is maximized where the marginal utility per dollar is equal for all products
(T/F) A shortage would result from either a decrease in supply or an increase in demand.
True
(T/F) Allocative efficiency occurs when the mix of goods and services produced is the most desired by society.
True
(T/F) An increase in the price of milk will cause a decrease in the demand for breakfast cereal.
True
(T/F) Everyone has a comparative advantage in something, but not everyone has an absolute advantage in something.
True
(T/F) Holding other things constant means identifying other relevant factors and fixing their value at a specified or constant level.
True
(T/F) If a firm's total cost increases by $25 when it produces an additional unit of output, an economist would say that the marginal cost for that unit is $25.
True
(T/F) If markets are left unregulated by the government, then at the market equilibrium price the sum of consumer surplus and producer surplus is maximized.
True
(T/F) One of the problems of a minimum wage is that it can create a surplus of workers.
True
A decrease in the price of milk will cause an increase in the demand for breakfast cereal.
True
A decrease in the price of milk will cause an increase in the supply of ice cream.
True
A price floor set above the equilibrium price will result in quantity supplied exceeding quantity demanded.
True
Countries should specialize in producing those things in which they have a comparative advantage
True
If demand decreases for a particular good, then we can expect that the market price for that good will decrease and the quantity of the good sold in the market will decrease.
True
If supply increases for a particular good, then we can expect that the market price for that good will decrease and the quantity of the good sold in the market will increase.
True
Price elasticity of demand measures how responsive consumers are to changes in price.
True
Suppose a customer's willingness to pay for a product is $80, and the seller's willingness to sell is $65. If the negotiated price is $70, then producer surplus is $5.
True
Suppose the equilibrium price and quantity exchanged increase. The most consistent explanation for this observation is an increase in demand with no change in supply.
True
Talented people who are exceptional at everything do not have a comparative advantage in everything.
True
The following statement is an example of the law of demand: "The local record store has all their CDs on sale. I'm going to buy some right now."
True
A normal good is one for which the quantity demanded increases as income increases.
True A positive income elasticity of demand means that more of a good is demanded as income increases. Economists refer to such goods as normal goods. An inferior good refers to the situation where income elasticity of demand is negative, meaning less of a good is demanded when income increases.
(T/F) Keeping one's front yard neat and attractive can create a positive externality.
True As a result of attractive landscaping at one home, the values of neighboring properties may be higher which confers a benefit to the neighboring property owners even though the neighbors had no role in the landscaping; this is an example of a positive externality.
(T/F) Game theory can be applied in business, political science, military planning, and sports.
True Game theory has broad applications because it provides insights that enable predicting behavior of participants, particularly when the decisions of one party affect the decisions of another party.
As income increases, the demand curve for an inferior good shifts to the left.
True Inferior goods have an inverse relation to income. That is, higher income leads to lower demand for an inferior good and the reverse. The reduced demand for an inferior good as income rises is represented by the leftward shift of the demand curve, indicating a lower consumption at each price point.
An economy that finds new inputs or improves technology to use existing inputs in a more productive manner is pushing its PPF outward and can experience long-run economic growth.
True New inputs (perhaps in the form of population growth or the discovery of raw materials) or improving the use of existing inputs means an economy has a greater ability to produce goods and services, and this can lead to economic growth.
(T/F) In a perfectly competitive industry, one would expect that a natural disaster that decreases the production of a significant number of firms in the industry would cause market prices to rise.
True The impact of a natural disaster that reduces production is a shift in the market's supply curve to the left, indicating fewer producers are available to service the market's demand. This results in an increase in prices.
A price ceiling is a government-mandated maximum price at which a good can be sold.
True This form of price control is designed to insulate consumers from the price-increasing effects of market forces. These controls are rarely used and are normally reserved for external events that cause a dramatic disruption in the operation of a market, such as wars, natural disasters, or politically driven oil embargos.
(T/F) The utility maximization rule states that a consumer's total utility is maximized, given a budget and product prices, when the marginal utility per dollar of the last unit of every good consumed is equal.
True Under this rule, the last dollar spent on each good delivers the same marginal satisfaction or well-being to the consumer. No other combination of purchases will deliver higher total satisfaction/well-being.
(T/F) Market power reaches its maximum potential in a monopoly.
True When a business has market power, it means that the business has some influence over both the prices of its products and its output. Because a monopoly is protected from competition (which might undercut its prices) by barriers to entry, it has the highest level of market power.
A tradeoff analysis entails assessing the costs and benefits of different alternatives.
True; A tradeoff analysis compares the costs and benefits of different alternatives. The selected option is the one that has the higher net benefit (benefits minus costs).
What costs increase as the level of production increases?
Variable costs
Consider the demand for olive oil. What would happen to the demand for olive oil if a study confirming its beneficial health effects is published at the same time that an investigative report finds that much of the olive oil imported into the country is actually sunflower oil that has been dyed?
We would expect demand to shift in each direction, but the final position will depend on which event has the bigger impact on demand.
Describe characteristics of wealthy countries that lead to new ideas.
Wealthy countries tend to have strong educational systems and provide incentives for its citizens to work hard. These qualities along with a government free of corruption, a strong legal system, and a strong monetary system enable its citizens to create new or improved products and to benefit from inventions, now and in the future.
vicious cycle
When a network good does not reach its tipping point, and therefore does not increase in value enough to retain its customers, customers leave the network, thereby further diminishing the value of the good until all customers leave the network.
grim trigger
When one player defects, the other refuses to cooperate again (no forgiveness).
mutual interdependence
When only a few firms constitute an industry, each firm must consider the reactions of its competitors to its decisions.
shutdown point
When price in the short run falls below the minimum point on the AVC curve, the firm will minimize losses by closing its doors and stopping production. Because P < AVC, the firm's variable costs are not covered; therefore, by shutting the plant, losses are reduced to fixed costs only.
Which statement is not correct? The sum of consumer and producer surplus increases as markets become more efficient. A reduction in total consumer and producer surplus indicates markets have become less efficient. When prices are below market equilibrium, the sum of consumer and producer surplus decreases. When prices are above market equilibrium, the sum of consumer and producer surplus increases. All are correct
When prices are above market equilibrium, the sum of consumer and producer surplus increases.
What benefit does society derive by allowing some monopolies to be created?
While a monopoly creates market power that typically results in higher prices and less output, likely yielding economic profits and reduced consumer surplus, there is still some possible benefit to society from a monopoly. Monopolies can be the drivers of innovation. Inventors and other creative people are incented to invest in products and services produced by monopolists because of the possibility of realizing large economic profits (Because a monopolist is the only producer of the product or service)
How does the budget line change if the budget is reduced?
With a decrease in the budget (the maximum the consumer is willing to spend), the budget line moves to the left (closer to the origin) parallel to the original budget line. This shows that the reduction in budget or income has reduced the combinations of goods the consumer can purchase.
Suppose consumers find two brands of breakfast cereal equally tasty and nutritious. Brand A increases its price but brand B does not. What will happen in the market, and how would this be depicted on the demand curves for each brand?
With the increase in brand A's price, consumers will buy less of that product, a reduction in the quantity demanded. This will be shown on brand A's demand curve by a movement along its demand curve—the curve itself will not move. Consumers will buy more of brand B, an increase in demand. This will be depicted by a rightward shift in brand B's demand curve.
Do changes in product prices impact the budget line?
Yes, changes in product prices do change the budget line even without changes in income. For example, if the price of a good declines, the consumer can now purchase more of the good whose price has declined or possibly more of the good whose price is unchanged. A decrease in a good's price is shown by moving the budget line's intercept with the good's axis out from the origin. This shows that a greater number of choices are now available to the consumer.
In 2007, the Wall Street Journal reported on a dispute in Bend, Oregon. Susan Taylor decided to hang her laundry out to dry on a clothesline. Neighbors said it was unsightly. Susan said she was saving energy. Could the Coase theorem work in this case?
Yes, if transaction costs are minimal. The Coase theorem states that if transaction costs are minimal, a bargain struck between the beneficiaries and victims of externalities will be efficient from a resource allocation perspective.

Bayram had the opportunity to choose between two investments. The first investment was described as having a 30% chance of succeeding, while the second investment was described as having a 70% chance of failing. Bayram opted for the first investment, because he thought it sounded less risky than the second investment. The chances of succeeding and failing are the same for the two investments, however, which implies that Bayram is subject to:
a framing bias

The local school district wants to close down a neighborhood high school because its outdated heating and cooling systems make it too expensive to operate compared to the new high school being built nearby. Parents who are against closing the neighborhood school argue that the $2 million dollars spent refurbishing the school over the last few years will be wasted if the school is shut down. This argument is an example of:
a sunk cost fallacy

In many instances, competitive companies could agree with each other on key strategic items, and produce higher profits than what competition allows. Reasons this is not done include the _____, and the illegality of collusion.
absence of trust between companies. Since collusive agreements are illegal in the United States, they can't be written in a contract and are not enforceable in court. This means that such agreements (in addition to risking jail time for company executives) rely on companies trusting each other when they could benefit by departing from the agreement if the other stays with the agreement.

In the fictitious country of Amelia, the wage earners in each quintile earn 20% of total income. What would be the shape of the Lorenz curve for Amelia?
an upward-sloping straight line Lorenz curves cumulate households of various income levels on the horizontal axis, relating this to their cumulated share of total income on the vertical axis. Amelia has equal distribution of income, which means that the Lorenz curve would be an upward-sloping straight line.
A Nash equilibrium:
assumes that each player chooses his or her best strategy.

consumers expect prices to rise in the near future
Price discrimination by a monopolist leads to the firm earning higher profits but it also delivers benefits to:
consumers, because prices are lowered to potential consumers who otherwise might not have been able to buy the good. Consumer surplus is reduced when a monopolist price discriminates - charges different prices to different consumers - and the reduction in consumer surplus becomes additional profit for the monopoly. Nevertheless, there is a benefit to some consumers from a monopolist's price discrimination because they are offered a lower price for the product. This enables them to participate in the market where previously they couldn't because the price was too high for them.

Monopolistically competitive markets and perfectly competitive markets do NOT share which characteristic? many firms in the market zero economic profits in the long run differentiated products ease of entry into the market
differentiated products
The opportunity cost of producing more of a good increases because of:
diminishing returns to inputs As resources are shifted from the production of one good to another, the most productive resources in production of the new good are shifted first. With further increases in output, less productive resources are deployed. The result is that more resources will be required to support a given level of additional output while at the same time causing a greater decline in the output of the original good.
If a firm increases its inputs by 80% and its output increases by 60%, then this would be an example of:
diseconomies of scale

Three barriers to entry that prevent firms from entering a market and competing in the market are control over inputs, economies of scale, and:
government protection through patents and copyrights Barriers to entry give the monopolist protection from competition enabling the firm to exercise more market power and influence over setting prices and output levels.
An effective (or binding) price ceiling is a situation in which:
government sets the maximum price for a good below its free market equilibrium price. A price ceiling is effective only if it is set below the free market equilibrium price. An effective ceiling prevents the price from rising to market equilibrium levels.
A certain brand of breakfast cereal increases its price by 20%, while other brands keep their prices unchanged. The quantity of cereal sold by the brand that increases its price declines, and the quantity sold by the other brands increases. In this case, the cross price elasticity of demand between the cereal of the brand that increases its price and the cereals produced by other brands is:
greater than 0 When consumers greet a price increase by switching to another good that has a lower or no price increase, and which delivers similar satisfaction to the consumer, they are substituting away from the good for which the price increased. In such cases, when the goods are substitutes, the cross price elasticity of demand between the pair of goods will always be positive or in other words greater than 0.

In a perfectly competitive market, each firm's demand curve is:
horizontal While in perfect competition the market demand curve slopes downward and to the right, the demand curve for individual firms is horizontal, meaning each of the small firms in the industry can sell as much as it wants without reducing price because each firm is too small to influence the market's price.
The production possibilities frontier (PPF) shows:
how much an economy can produce when using all of its inputs efficiently. The PPF displays both the total output capability of an economy but also the tradeoff between producing more of one good and less of another.
The firms in a perfectly competitive market produce _____ products.
identical One of the distinguishing characteristics of a perfectly competitive market is the nearly identical products the market's competitors produce. Other important distinguishing characteristics are the presence of many small firms in the market and the absence of entry/exit barriers.
A combination of goods that lies outside the PPF is:
impossible An output level that is outside the PPF is impossible because the PPF defines combination of outputs that are possible within the available resources of the economy. There are insufficient resources in the economy to support combinations of goods that lie outside the PPF.
A(n) _____ can cause the PPF to expand.
improvement in production technology Improvements in production technology can result in the economy expanding its aggregate output, which would be depicted by the PPF moving away from the origin point.
Which statement is a key idea in economic thinking? Incentives matter. Scarcity exists for the poor but not for the rich. The value of a good can be objectively measured and is the same for everyone. All of these are key ideas in economic thinking.
incentives matter

increase
If a cartel member is considering cheating in order to earn profits, it should:
increase the quantity it sells at the quota price
A(n) _____ good is a good for which the amount consumed declines as a consumer's income increases.
inferior Inferior goods are those with a negative relationship between income changes and quantity demanded. As income increases, the quantity demanded of the good declines, and the income elasticity for the good is a negative number.
Farmer Ted sells winter wheat in a perfectly competitive market. The market price for a bushel of winter wheat is $9. Ted has two hundred and seventy bushels of wheat to sell. If his total variable cost is $2,000 and his total fixed cost is $500, then Ted:
is minimizing his losses
Total utility:
is the total satisfaction derived from the consumption of a given quantity of a good

it adds to congestion and pollution
The Coase theorem claims that, in the case of tobacco:
it does not matter who is given the property rights to the air, as long as the parties involved are allowed to bargain.
Common property resources tend to be exploited quickly because:
it is not possible to prevent someone from using the resource. When it is not possible to prevent someone from enjoying a good or service (when a good or service is a nonexcludable good), many people will consume it even if the value of consuming it is low, without considering the problems caused by over-consumption.
Which of these is an example of consumers creating a negative externality? A tanker ship leaks oil into a harbor. Air traffic from a nearby airport reduces property values. Litter is found in an area around a fast-food restaurant. A fast-food restaurant fails to provide medical benefits to employees.
litter is found in an area around a fast-food restaurant
A perfectly competitive industry is characterized by:
many small firms each producing identical products and no barriers to entry These characteristics yield the most competitive market structure. Because each firm is but a small part of the overall market, no firm can influence the market price.
People use _____ to determine how many hours to work, and businesses use _____ to determine how much of their product they are willing to supply to the market.
marginal analysis; marginal analysis
The additional cost of producing one more unit of a good is:
marginal cost
A firm's profit is maximized at the output level where
marginal cost equals marginal revenue
The price charged by a firm in a perfectly competitive market always equals its:
marginal revenue Since the price of a firm's product in a perfectly competitive market doesn't change as it sells additional units (shown by a horizontal demand curve), its marginal revenue (the additional revenue from selling additional units) is equal to the unit price the firm charges for its product.
The profit-maximizing level of output for a firm in a perfectly competitive market occurs where:
marginal revenue equals marginal cost At the output level where a firm's marginal revenue (the additional revenue from selling additional units) equals its marginal cost (the additional cost generated by producing additional units), the firm's total profits cannot be improved by producing a different number of units.
To maximize profits, the monopolist produces at a level of output in which:
marginal revenue equals marginal cost, and then the monopolist charges the highest price for that output indicated by the demand curve The profit-maximizing condition for a monopoly is the same as for perfect competition - the output level where marginal revenue equals marginal cost. The profit-maximizing price is determined by the highest price consumers are willing to pay for that output level as determined by the demand curve.
At an all-you-can eat buffet, a person will stop eating when:
marginal utility is equal to zero
Consumers maximize total utility when the _____ all goods.
marginal utility per dollar is equal for
In the mid-1970's, Sony released a "Beta" format videotape, which could only be played on Beta video players. Although this format was launched before the competing VHS format, fewer and fewer companies continued to use the Beta format and fewer and fewer consumers purchased Beta video players. It was eventually replaced almost entirely by VHS format in the late 1980's. The Beta format likely never reached:
market equilibrium Market equilibrium occurs after the tipping point at the intersection of the downward-sloping portion of the network demand curve and the marginal cost curve.
The inability of a market to generate a socially optimal quantity or price of a good is called a(n):

In a 2008 case before the Supreme Court regarding older power plants and how best to protect fish and aquatic organisms, Justice David Souter remarked, "The difficulty that I have is if you are going to apply . . . a cost-benefit analysis, I'm not sure how it would work. Are a thousand plankton worth a million dollars?" Justice Souter's question points out the difficulty of:
measuring nonmarket or intangible aspects of public projects.
A firm earning a zero economic profit is _____ the financial expectations of its investors.
meeting Because a firm's opportunity costs include the returns investors forgo in order to invest in the firm, the firm's zero economic profit produces an acceptable return for investors.
A firm earning zero economic profit is:
meeting its investors' minimum expectations and covering its opportunity costs
If firms in a perfectly competitive market are earning positive economic profits in the short run, one would expect that in the long run:
new firms would enter the market and market prices would decrease Because there are no barriers to entry, the positive short-run economic profits of existing firms in perfect competition will attract new competition. This increase in supply will cause market prices to decrease to the point where all the firms earn zero economic profits.
Public goods are _____ and _____.
nonrival and nonexcludable These characteristics make it difficult for the private market to produce public goods because firms would not be able to earn profits from these goods. As a result, the government or a nonprofit is often the provider of such goods.

Suppose the Grant family earns $20,000 and that the poverty threshold for their family is $15,000. How would this family be classified according to the Census Bureau?
not poor The Grant family's income to poverty ratio is 1.33. The ratio is $20,000:$15,000 or $20,000/$15,000 or 1.33. The Census Bureau considers people who live in families with ratios below 0.5 to be "severely or desperately poor." Those with ratios between 0.5 and 1.0 are "poor," and people with ratios above 1.0 but less than 1.25 (less than 25% above the poverty threshold) are considered to be "near poor." Families with ratios over 1.25 are not considered poor.

"Nonexcludable" means that:
once a good is provided, no one can be prevented from enjoying it. This is true regardless of how the production of the good is funded. An example of a nonexcludable good is national defense. Even if someone is in prison for non-payment of taxes, they are still protected by the country's military forces
A nonrival good is one for which
one person's consumption of the good does not diminish another person's enjoyment of the good. An example of a nonrival good is satellite radio. One person listening to a satellite radio program does not diminish the possibility of someone else enjoying the same program.

opportunity cost
If the government of Spain decides to spend less on the military and more on health care, the forgone spending on military items represents the:
opportunity cost of the extra health care
Products that generate external costs are generally _____ or _____.
over-produced; over-consumed Because the costs to society may be excluded from private transactions, the cost to produce the good or service is artificially low (from society's perspective), and this leads to an artificially low price for the good or service. This causes the over-consumption or over-production.
Because they are so sure of their ability to pick winners, some people hang on to a stock even in the face of overwhelming evidence that its price is going to drop. These people are subject to:
overconfidence

people make rational decisions
Firms in all market structures experience some type of control over price, EXCEPT firms whose market structure is a(n):
perfect competition
A change in the quantity demanded of a good results from a change in the:
price of a good Only a change in price causes a change in quantity demanded. This is represented graphically by movement along the demand curve, not by a shift of the curve.
A firm is a ____ if its actions have no impact on the market price of a good.
price taker In the perfect competition market structure, there are many relatively small firms producing identical products and there are no barriers to entry. This means firms in this industry must take the market price as given.
A monopoly harms consumers because:
prices are higher and output is lower than if the industry was perfectively competitive. The existence of market power due to the monopolist being the only firm producing a given product and protected from competition by barriers to entry results in higher market prices and reduced levels of output. This reduces consumer surplus.
Mike constructed a beautiful backyard landscape. He also built a tall wooden fence around his yard. With the fence in place, the good that the landscape brings to the neighborhood becomes a:
private good because Mike can exclude people from enjoying the landscape.
Suppose that a firm in an oligopoly market faces a kinked demand curve. If its marginal cost decreases, the firm will:
produce the same quantity and charge the same price unless marginal cost moves out of the range of discontinuity in marginal revenue. Unless marginal cost shifts out of the range of discontinuity in marginal revenue, the profit-maximizing level of output will not change and neither will the price. It is the discontinuity that results in the price stability in oligopolies.
A combination of goods represented by a point on the PPF is considered efficient because the economy is:
producing goods using the fewest inputs possible Efficiency means the economy is getting the most output for its expenditure of inputs.
When goods are produced at the lowest possible cost, an economy is said to have achieved:

quantity demanded for iPads falls
When a customer chooses to accept an item of value from a business because it requires no incremental spending on the part of the customer, the customer is demonstrating the principle that:
rational people think at the margin; When thinking at the margin, decision makers are considering only the costs and benefits that result from the decision under consideration. In this case, the incremental cost is zero, while the incremental benefit is the value of the item received. A rational individual will only consider the additional or incremental cost and benefit and ignore all other costs and benefits.
Short-run economic growth is illustrated on a PPF diagram by movement from inside the PPF toward the PPF. A situation where this would be an appropriate depiction is in an economy:
recovering from a recession As an economy recovers from a recession, previously unemployed people return to work and formerly underutilized factories return to full production. Both are examples of an economy growing in the short run by increasing the productive use of existing but underutilized or idle resources. On a PPF diagram, this is depicted by moving toward the PPF.
Which is NOT a source of economic growth? increasing business investment reducing the level of international trade reducing barriers to financial aid for higher education increasing research and development
reducing the level of international trade
When monopolies waste resources attempting to prevent other firms from competing with them, it is referred to as:
rent seeking To protect their monopoly position and the resulting market power and profits, many such firms expend substantial resources to prevent new competition from entering their market. This inefficient spending is directed to lobbying, extending patents, or restricting licenses. It is called rent-seeking behavior.

second-degree price discrimination
When players in a game select a dominant strategy, they are:
selecting the best strategy regardless of the strategies their opponents choose. Identifying a dominant strategy provides a game participant with a tool to respond to any action of the participant's opponents because it provides the best outcome for the participant regardless of the strategy selected by the participant's opponents.
Market power enables businesses to:
set prices and reap profits Because achieving market power gives a firm some control over prices and the level of output, it is more likely to earn positive economic profits. Economic profits are achieved when revenues are higher than the total of explicit and implicit costs.
If the United States experiences an inflationary episode in which prices of goods and services go up faster than incomes, budget lines for U.S. consumers will:
shift inward
Assume a farmer's land is equally productive in growing corn or potatoes and is currently producing both. If the price of corn increases but the price of potatoes does not change, the farm's supply curve for potatoes will:
shift to the left, and fewer potatoes will be produced at each price level. Potatoes and corn in this example are production substitutes. When the price of corn increases, the farmer shifts land to increase production of corn (replacing potatoes) to take advantage of corn's higher price. This is represented by a shift of the potato supply curve to the left.
When price ceiling for a good is set below the free market equilibrium the result is a(n):
shortage If the price ceiling is set below the free market equilibrium price, the quantity demanded exceeds the quantity supplied. This causes a shortage, also called excess demand.
If an effective price ceiling is raised:
shortage decreases An increase in a price ceiling helps reduce the gap between quantity demanded and quantity supplied. Since an effective price ceiling creates a shortage, an increase in the price ceiling helps reduce the shortage.
Suppose that a major drought causes a 30 percent reduction in the peanut harvest. If there is no change in demand, this event would cause a _____ at the original equilibrium price, and the equilibrium price will therefore _____ and the equilibrium quantity will _____.
shortage; rise; fall

If the cross price elasticity of demand is positive for a given pair of goods, they are _____ and if it is negative, they are _____
substitutes; complements The cross price elasticity of demand measures the relationship between changes in price for one good and changes in quantity demanded for another good. A positive cross elasticity means that as price of one good increases, the consumption of the other good increases. Consumers switch from the good whose price has increased to the other good - therefore these goods are substitutes. A negative cross elasticity means that as the price for one good increases consumption of the other good declines. In this case, consumers consume less of the good whose price has increased and also the other good. Therefore they are complements or consumed together.

supply of flour to decrease
Improvements in technology that reduce production costs cause the _____ curve to shift to the _____, indicating a(n) _____ in the amount _____ at each price point.
supply; right; increase; supplied By reducing production costs, technological improvements increase producer profit per unit. This profit increase persuades the producer to increase production at each price level. In graphic terms, the supply curve shifts to the right.
One of the costs associated with a minimum wage is that it creates a:
surplus of workers A minimum wage has the same effect as other price floors. It causes excess supply. In this case, the minimum wage is enticing a greater number of workers into the job market than employers are willing to hire at that price; this causes a surplus of workers, also known as unemployment.
In an oligopoly, all the firms:
take their competitors into account when they make pricing decisions
A consumer is in equilibrium when
the addition to total utility per dollar is the same for every commodity.
If the prices of the two goods the consumer buys increase:
the budget line shifts closer to the origin
When a budget line shifts to the left, this means that
the consumer's income has decreased, or the cost of the two goods has increased
When a budget line shifts to the right, this means that
the consumer's income has increased, or the cost of the two goods has decreased
In the fictitious country of Amelia, the government taxes the wealthier residents and gives that tax money to the poorer residents. What would this taxing and transfer payment look like on the Lorenz curve?

In the mid-1970's, Sony released a "Beta" format videotape, which could only be played on Beta video players. Although this format was launched before the competing VHS format, fewer and fewer companies continued to use the Beta format and fewer and fewer consumers purchased Beta video players. It was eventually replaced almost entirely by VHS format in the late 1980's. The Beta format likely never reached this part of the network market demand curve.
the downward-sloping portion of the network market demand curve. The downward-sloping portion begins after the tipping point. The tipping point was never reached.
A combination of goods that lies inside the PPF is considered inefficient because:
the economy is capable of producing more of both goods. When the economy's resources are being underutilized, efficiency is lost and potential output is not being realized.
The demand curve for a monopolist is:
the industry demand curve
Consider that the corn industry is a perfectly competitive industry with constant returns to scale. The price per bushel is $2. If the long-run, minimum ATC is $1.50 per bushel, it should follow that (ceteris paribus):
the long-run price will be $1.50 per bushel.

While prisoner's dilemma outcomes may produce worse results for competing companies than other alternate outcomes, such dilemmas can benefit:
third parties who do business with the competing companies. When firms are competitive, their interactions produce less attractive outcomes than available when they cooperate. However, this competition can benefit consumers - third parties. Lower prices for consumers are an example of how competition among firms may lead to a prisoner's dilemma outcome that is bad for both firms but good for the consumers.
In the mid-1970's, Sony released a "Beta" format videotape, which could only be played on Beta video players. Although this format was launched before the competing VHS format, fewer and fewer companies continued to use the Beta format and fewer and fewer consumers purchased Beta video players. It was eventually replaced almost entirely by VHS format in the late 1980's. The Beta format likely never reached the:

we face tradeoffs in nearly every choice we make
Firms in perfectively competitive industries earn _____ economic profits.
zero Since a firm earning zero economic profit is covering its opportunity cost (and as a result is earning an accounting profit), such an outcome is not as bad as it sounds.
