"Looked at from the standpoint of incremental revenue (huge) minus these incremental expenses (modest), the Postal Service could very easily have come to the conclusion that, even at $2 a package, the Amazon contract was likely to be highly profitable." Sources: Eli Rosenberg, "Trump Said Amazon Cost The the USPS 'Billions.' But the Post Office Has a Different Explanation." Washington Post, May 11, 2018. What does the writer mean by "incremental revenue" and "incremental cost"? Why would he focus on incremental revenue and incremental cost rather than on total revenue and total cost? "Incremental" means the same thing as
"marginal." If the marginal revenue exceeds the marginal cost, the USPS's profit will increase. If the marginal cost exceeds the marginal revenue, the USPS's profit will decrease.

According to an article on barrons.com, earnings increased for Starbucks in early 2019 partly because of lower costs due to "streamlined operations." Source: David Marino-Nachison, "Starbucks Stock Is Up, but So Are Expectations, Analyst Says," barrons.com, April 8, 2019. Explain the effect of this cost decline on the price of a Starbucks cappuccino, on the quantity of cappuccinos a representative Starbucks coffeehouse sells, and on the profit of this Starbucks coffeehouse. Assume that the demand for Starbucks cappuccinos is unchanged. When Starbucks streamlines its operations, its MC curve shifts downward and its ATC curve shifts downward. The lower cost causes Starbucks to increase the quantity of cappuccinos that it sells and to decrease the price of cappuccinos. Starbucks's profit increases.

From 1979 to 2015, China had a policy that allowed couples to have only one child. (Since 2016, couples have been allowed to have two children.) The one-child policy caused a change in the demographics of China. Between 1980 and 2017, the share of the population aged 14 and under decreased from 36 percent to 18 percent. And, as parents attempted to ensure that the lone child was a son, the number of male children relative to female children increased. Sources: World Bank, World Development Indicators, February 2019; and Steven Lee Myers, Jin Wu, and Claire Fu, "China's Looming Crisis: A Shrinking Population," New York Times, January 21, 2019. Part 2 How has the one-child policy changed the relative demand for goods and services in China?
It has undoubtedly shifted away from goods and services appealing to youthful buyers, particularly youthful female buyers.
Is it possible for technological change to be negative? If so, give an example.
It is possible for technological change to be negative. An example is when a hurricane damages a firm's facilities.
Under the Social Security retirement system, the federal government collects a tax on most people's wage income and makes payments to retired workers above a certain age who are covered by the system. (The age to receive full Social Security retirement benefits varies with the year the worker was born.)

It provides a means of spreading the risk of bad outcomes. It is a transfer program.
JAB, a German company that now owns both Peet's and Intelligentsia, has been focusing on sales of cold-brewed coffee, which it sells in supermarkets and convenience stores. According to an article in the Wall Street Journal, "Making and distributing cold-brewed coffee, in particular, is challenging and expensive because it requires a lot of coffee beans to extract the flavor." Source: Zeke Turner and Julie Jargon, "The Secretive Company That Pours America's Coffee," Wall Street Journal, March 7, 2018. If cold-brew coffee is more costly for JAB to produce than is conventional ground coffee or hot coffee sold in coffeehouses (JAB sells those types of coffee as well), why would JAB focus on it?
JAB is following a strategy of differentiating its product from those offered by competing firms
Suppose Jill Johnson operates her pizza restaurant in a building she owns in the center of the city. Similar buildings in the neighborhood rent for $4,000 per month. Jill is considering selling her building and renting space in the suburbs for $3,000 per month. Jill decides not to make the move. She reasons, "I would like to have a restaurant in the suburbs, but I pay no rent for my restaurant now, and I don't want to see my costs rise by $3,000 per month." Part 2 What do you think of Jill's reasoning? Part 3
Jill is incorrectly ignoring the opportunity cost of using the building she owns.
Is Jill Johnson correct when she says the following: "I am currently producing 10,000 pizzas per month at a total cost of $50,000. If I produce 10,001 pizzas, my total cost will rise to $50,050. Therefore, my marginal cost of producing pizzas must be increasing."
Jill's average total cost of production is increasing, so her marginal cost of producing pizzas must be increasing.

An article in the Wall Street Journal discussing the smartphone market notes that industry analysts make the following observation: Apple's "biggest advantage has been its role as the only seller of devices featuring its iOS operating system. The iOS monopoly means users who switch to a rival device would have to learn a new system and potentially give up some stored information, analysts say." Source: Tripp Mickle, "Diverging Fortunes: High Prices Propel Apple, Sink Samsung," Wall Street Journal, August 1, 2018. Does Apple have a monopoly on smartphones?
No, Apple is not the only producer of smartphones in the market, so it does not have a monopoly on smartphones.
Is zero economic profit inevitable in the long run for a monopolistically competitive firm?
No, a firm could try to continue making a profit in the long run by reducing production costs and improving its products
According to an article on crainsnewyork.com, in 2018, the Metropolitan Museum of Art (the Met) in New York City had record attendance of 7.36 million, an increase of 5 percent over the previous year. During 2018, the Met had also increased the price of attendance. Source: Miriam Kreinin Sinclair, "Met Museum Attendance, Revenue up a Year After Imposing Fee," crainsnewyork.com, January 4, 2019. a.

A student looks at the data in the table to the right and draws this conclusion: "The marginal product of labor is increasing for the first 3 workers hired, and then it declines for the next 3 workers. I guess each of the first 3 workers must have been hard workers. Then Jill must have had to settle for increasingly poor workers." Part 2 Do you agree with the student's analysis? Briefly explain.
No. Marginal product initially increases due to specialization and then decreases due to the law of diminishing returns

No. The average total cost curve will be continually increasing.
Do you agree that health insurance is meant for people who end up getting sick?
No. While it obviously directly benefits those who do become sick, it indirectly benefits all since everyone faces some risk of sickness. There is a "psychic" benefit to knowing that one is "covered" if sickness should befall them.

Source: Daniel Yang and Stacy Wegner, "Apple iPhone XS Max Teardown," techinsights.com, October 3, 2018. Can we conclude from this information that Apple was making a profit of about $796 on each of these iPhones?
No; to calculate economic profit, all implicit and explicit costs relating to the production of the iPhone must be subtracted from the total revenue earned from selling the phones, so Apple made less than $796 on each iPhone.

A student remarks: "If firms in a monopolistically competitive industry are earning economic profits, new firms will enter the industry. Eventually, the representative firm will find its demand curve has shifted to the left, until it is just tangent to its average cost curve and it is earning zero profit. Because firms are earning zero profit at that point, some firms will leave the industry, and the representative firm will find its demand curve will shift to the right. In long-run equilibrium, price will be above average total cost by just enough so that each firm is just breaking even." Is the analysis correct or incorrect?
The analysis is incorrect. Firms will not leave the industry when earning zero economic profit. When the firm's demand curve is tangent to its average cost curve it is still earning zero economic profit.

In 1916, the Ford Motor Company produced 500,000 Model T Fords at a price of $440. The company made a profit of $60,000,000 that year. Henry Ford told a newspaper reporter that he intended to reduce the price of the Model T to $360, and he expected to be able to sell 800,000 cars at that price. Ford said, "Less profit on each car, but more cars, more employment of labor, and in the end we get all the total profit we ought to make." Part 2 a. Did Ford expect the total revenue he received from selling Model Ts to rise or fall following the price cut?
Rise because he assumed demand was elastic.

Briefly explain whether you agree or disagree with the following argument: Adam Smith's idea of the gains to firms from the division of labor makes a lot of sense when the good being manufactured is something complex like automobiles or computers, but it doesn't apply in the manufacturing of less complex goods or in other sectors of the economy, such as retail sales. Part 2
The argument is incorrect. Gains from division of labor will occur whenever production of a good or provision of a service has multiple tasks. Your answer is correct.
Older oil wells that produce fewer than 10 barrels of oil a day are called "stripper" wells. Suppose that you and a partner own a stripper well that can produce eight barrels of oil per day and you estimate that the marginal cost of producing another barrel of oil is $80. In making your calculation, you take into account the cost of labor, materials and other inputs that increase when you produce more oil. Your partner looks over your calculation of marginal cost and says: "You forgot about that bank loan we received two years ago. If we take into account the amount we pay on that loan, its adds $10 per barrel to our marginal cost of production." Which of the following statements is most true?
The bank loan should not be included in marginal cost because it cannot be avoided by not producing another barrel.
Stuart Butler of the Brookings Institution argues that "there is much more to achieving good health than just spending money on medical care. We could save billions of dollars repairing hip fractures for seniors, for instance, by investing a fraction of that money in such things as safer bathrooms and non-slip carpeting." Source: Stuart M. Butler, "There Are Good Reasons to Be Optimistic about True Health Reform," brookings.edu, August 14, 2018. Would changes of this type be observable in the health outcomes policymakers use to compare the health care systems of different countries? Which of the following statements is true?
The changes Butler proposed might increase well-being for the reasons he states. But, it seems unlikely that the changes would improve the health outcomes that policymakers typically focus on (curing diseases or injuries after people have already experienced them). Your answer is correct.

About 80 of these small vegetable stands operate along a handful of streets in that neighborhood. Most supermarkets buy vegetables from large wholesalers. In contrast, the entrepreneurs who run the stands in Chinatown buy from smaller wholesalers located in the neighborhood. These wholesalers, in turn, buy primarily from smaller family farms, some located overseas. Because these wholesalers make several deliveries per day, the owners of the stands do not have to invest in substantial storage space and the refrigerators that supermarkets use to keep vegetables fresh. The reporter compared prices for vegetables sold by these stands with vegetables sold by her supermarket: "In almost every case, Chinatown's prices were less than half what I would pay at the supermarket. Among the bargain
Yes, the owners of these vegetable stands are likely earning an economic profit because they remain in business.
The article also explained that New York City experienced an increase in the number of tourists during 2018 and that during the year, the Met offered several exhibitions that received good reviews. Does this additional information help you answer the question in part (a)?
Yes, this additional information reinforces the increase in demand for visits to the Met in part (a).
According to an article in the Wall Street Journal in early 2019, the price of oil produced in the United States had increased by 25 percent since the beginning of the year. At the same time, U.S. oil production was at a record high. Source: Dan Molinsky, "Oil Prices Decline as U.S. Crude Production Hits Record," Wall Street Journal, February 21, 2019. a. Are these two facts alone, holding everything else constant, consistent with a movement along the supply curve for oil?
Yes. A higher price of oil causes an increase in the quantity of oil supplied, which we show by a movement upwards along the supply curve for oil.
Is it possible for average total cost to be decreasing over a range of output where marginal cost is increasing? Briefly explain.
Yes. If marginal cost is less than average total cost, then average total cost will be decreasing.
If you own the only hardware store in a small town, do you have a monopoly? Part 2
Yes. You would have a monopoly if your profits are not competed away in the long run.

In recent years, fewer households have been relying on traditional cable television to provide entertainment. Traditional cable television is sometimes called "pay TV." According to an article in the Wall Street Journal, "The pay-TV decline comes as many U.S. households are turning to the internet for entertainment and canceling their traditional subscriptions, a phenomenon called cordcutting." Source: Drew FitzGerald and Benjamin Mullin, "Outlook for Traditional TV Goes from Bad to Worse," Wall Street Journal, November 19, 2018. Is the decline in the number of cable television subscriptions likely the result of a movement along the demand curve for cable television or a shift in the demand curve? What information would you need to be confident in your answer? The decline in the number of cable television subscriptions is likely the result of
a leftward shift in the demand curve, but you would need to have information on changes (if any) in the price of cable television subscriptions to be sure.
Steven Pearlstein, a columnist for the Washington Post, observed: "Arthur Okun's book...Equality and Efficiency: The Big Tradeoff, remains a classic." Source: Steven Pearlstein, "Five Myths About Capitalism," Washington Post, September 28, 2018. Why is there a trade-off between equality and efficiency? Why might an economist write an entire book on the subject? There is a trade-off between equality and efficiency because
a more equal distribution of income reduces incentives to work and invest. An economist can write an entire book on the subject because the trade-off involves complicated normative and positive issues.

An article in the Wall Street Journal on the market for traditional canned tuna stated the following two facts: i. Firms selling traditional canned tuna are struggling to connect with millennial and generation Z consumers, "who favor fresher, less-processed options" in the food they eat. ii. Firms selling traditional canned tuna are facing competition from firms that offer tuna for sale in "pouches and kits with trendy flavors or as a healthy snack." Source: Jesse Newman and Annie Gasparro, "The Trouble With with Tuna: 'A Lot of Millennials Don't Even Own Can Openers,'" Wall Street Journal, December 2, 2018. a. From this information, can we conclude that falling sales of traditional cans of tuna is likely the result of a movement along the demand curve for traditional cans of tuna or a shift in the demand curve? The falling sales of traditional cans of tuna are the result
a shift in the demand curve for tuna to the left.

An article on Allbirds athletic shoes, which are made with merino wool uppers, made the following three points: a. The shoes "are a favorite of striving venture capitalists and celebrities." b. The shoes "are a staple in the offices of seemingly every technology startup." c. It quoted one of the founders as stating that the goal of the firm was to sell shoes "focused on delivering everyday comfort."

If you were working for Allbirds and a manager asked you to forecast the future demand for its shoes, why might (a) and (b) concern you? Why might you be happy to hear the co founder make the statement quoted in (c)? As a forecaster working for Allbirds, you should be concerned about point (a) and (b) because
both limit the size of the market. On the other hand, increased everyday comfort brought from the shoes may increase the demand for the shoe, causing an increase in sales.

The goal of the Google Books project is to produce a digital version of every book ever written. An academic paper by Abhishek Nagaraj of University of California, Berkeley and Imke Reimers of Northeastern University analyzed the effect of Google Books on the market for print, or physical, books.

Source: Abhishek Nagaraj and Imke Reimers, "Digitization and the Demand for Physical Works: Evidence from the Google Books Project," February 21, 2019. Does this paper indicate that digital books and print books are substitutes or complements? The findings of Nagaraj and Reimer show that digital and print copies of books are
complements because the decrease in the price of digital books to zero is causing an increase in the quantity demanded for print copies of the same book.

Suppose that the market for athletic shoes is initially in equilibrium at point A. Further suppose the demand for athletic shoes increases rapidly during 2020. At the same time, six more firms begin producing athletic shoes. A student remarks that, because of these events, we can't know for certain whether the price of athletic shoes will rise or fall. Part 2 The student's remarks (that, because of these events, we can't know for certain whether the price of athletic shoes will rise or fall) is

Some economists and policymakers have argued that one way to control federal government spending on Medicare would be to have a board of experts decide whether new medical technologies are worth their higher costs. If the board decided that they are not worth the costs, Medicare would not pay for them. Other economists and policymakers argue that the costs to beneficiaries should more closely reflect the costs of providing medical services. This result might be attained by raising premiums, deductibles, and co-payments, or by "means testing," which would limit the Medicare benefits high-income individuals receive. Political columnist David Brooks has summarized these two ways to restrain the growth of spending on Medicare: "From the top, a body of experts can be empowered to make rationing decisions.... Alternatively, at the bottom, costs can be shifted to beneficiaries with premium supp

In the United States, to receive a medical license, a doctor must complete a residency program at a hospital. Hospitals are not free to expand their residency programs in a particular medical specialty without approval from a Residency Review Committee (RRC), which is made up of physicians in that specialty. A hospital that does not abide by the rulings of the RRC runs the risk of losing its accreditation from the Accreditation Council for Graduate Medical Education (ACGME). The ACGME and the RRCs argue that this system makes it possible to ensure that residency programs do not expand to the point where they are not providing residents with high-quality training.

Consider an organization dedicated to helping low-income people. The members of the organization are discussing alternative methods of aiding the poor, when a proponent of one particular method asserts: "If even one poor person is helped with this method, then all our time and money would have been worth it." If you were a member of the organization, what reply best represents clear economic thinking? This attitude
ignores the fact that the cost of helping that one person has an opportunity cost of what those funds could have been used for to help other people.

en and Jerry are managers at the company, and they have this discussion: Ben: We should produce 4,000 lamps per month because that will minimize our average costs. Jerry: But shouldn't we maximize profits rather than minimize costs? To maximize profits, don't we need to take demand into account? Ben: Don't worry. By minimizing average costs, we will be maximizing profits. Demand will determine how high the price we can charge will be, but it won't affect our profit-maximizing quantity. Part 4 Evaluate the discussion between the two managers. Part 5 Ben's assertion that the firm should produce the quantity of lamps where average costs are minimized is Part 6
incorrect because profits are instead maximized at the quantity where marginal cost equals marginal revenue, which may be different since marginal revenue depends on consumer demand.
improvements in technology usually result in lower costs of production or new and improved consumer goods and services. Part 2 Assume that an improvement in medical technology results in an increase in life expectancy for people 65 years of age and older. This technological advance is likely to

increase the demand for print books, shifting the demand curve for print books to the right.
As part of his 2016 federal budget proposals, President Obama recommended significant changes to the federal student loan programs. Given your answer to the previous question, do you think President Obama was likely to have recommended changes that would increase, or changes that would decrease, the payments that borrowers would have to make? President Obama was likely to have recommended changes that would
increase the payments that borrowers would have to make so that the government would be paid back sooner.
This is

Is it possible that the supply curve for oil also shifted? Suppose you were told that managers at oil firms were convinced that oil prices in the future were going to be significantly lower than they are today. Would this fact help you answer the question? Given that managers at oil firms were convinced that oil prices in the future were going to be significantly lower than they are today,
it is likely that the supply curve for oil shifted to the right because firms will be more likely to increase the supply of oil today when prices are higher.

The Food and Drug Administration (FDA) is part of federal government's Department of Health and Human Services. Among its other functions, the FDA evaluates the safety and effectiveness of drugs and medical devices. FDA approval had to be granted before OraSure was allowed to market its home HIV test. In a centrally planned economy, the government decides how resources will be allocated. In a market economy, the decisions of households and firms interacting in markets allocate resources. Part 2 The regulation of the production and sale of drugs and medical devices in the United States is an example of how resources are allocated in a

slow rate of growth of labor productivity in health care. This is the correct answer. B. Distorted economic incentives for consumers and suppliers of health care. Your answer is correct. C. The development of advanced medical technology and new prescription drugs. This is the correct answer. D. An aging U.S. population.
A news story about the rental market for office space in big cities described the market as experiencing a "glut" and quoted a real estate broker as stating, "We are moving into greater opportunities for [office] tenants." Source: Keiko Morris, "Growing Glut of Office Supply to Pressure Rents Next Year," Wall Street Journal, December 18, 2018. Part 2 a. What does the article mean by a "glut"? What does a glut imply about the quantity of offices demanded relative to the quantity supplied? A glut is another term for a surplus. When a market experiences a glut, the quantity supplied is greater than the quantity demanded at the current price. Part 3 b. Is the real estate broker's observation that the market for office space was moving in a way that would result in greater opportunities for tenants connected to the fact that there was a glut in the market? The glut in the market will

Natural gas pipelines are a natural monopoly because
the average total cost curve for moving natural gas through a pipeline is still falling at the point where it crosses the demand curve.
Such data can be important in evaluating the effectiveness of a country's health care system because
the benefit may be greater than the cost of gathering the data.
The late Nobel Laureate Gary Becker once described how an economist should analyze the demand for butter: An economist "would want to consider the price of butter and probably the level of income, the price of margarine, and the size of the population as well. But [the economist] would neglect thousands and thousands of other variables...." Source: Gary Becker, Economic Theory, New Brunswick, NJ: Aldine Transaction, 2007, p. 5. a. What approach to analyzing demand curves is Becker describing?

the cost of its planes
An article in the Wall Street Journal on the recreational vehicle (RV) industry listed several factors that led to a larger quantity of RVs sold: a. Increasing confidence among households that their future incomes would rise b. Low-interest loans from banks to finance the purchase of an RV c. Falling gasoline prices d. "The 'glamping' trend that has seen a much younger generation embrace the RV lifestyle" Source: Spencer Jakab, "RV Stocks May Stay in the Wilderness," Wall Street Journal, January 1, 2019. Briefly explain whether the following factor caused a movement along the demand curve for RVs or a shift in the demand curve for RVs. If you believe the demand curve shifted, explain whether the curve shifted to the right or to the left. The 'glamping' trend that has seen a much younger generation embrace the RV lifestyle As a result of the change in the factor above,
the demand curve for RVs shifted to the right.
Macroeconomics is the study of
the economy as a whole, including topics such as inflation, unemployment, and economic growth.
Eric Topol, a cardiologist, has written about the potential for using artificial intelligence (AI) in health care. He argues that in the future, many patients will have the option to receive treatment in their own bedrooms, where they can be monitored by AI rather than be admitted to hospitals. Doing so would reduce the costs of delivering health care "because the large staff of doctors and nurses...would not be necessary in the future." Source: Sumathi Reddy, "A Doctor's Prescription for More AI in Medicine," Wall Street Journal, March 4, 2019. If the U.S. health care system makes greater use of AI, what are the implications for the trends shown in the maps in the Apply the Concept? Widely adopting AI in the U.S. health care sector will more likely result in
the employment of fewer workers as some tasks could be automated that are currently carried out by health care workers. If this outcome occurs, the trend highlighted in the maps would reverse.
Which of the following rights is given to the holder of a patent?

What are the four most important ways a firm becomes a monopoly? The four main reasons a firm becomes a monopoly are:
the government blocks entry, control of a key resource, network externalities, and economies of scale
Why are the analysts quoted in the article using "monopoly" in this context? In this sense, the analysts mean that
the iOS operating system is a significant barrier to other firms competing with Apple in the smartphone industry.
Economists believe that an activity should be continued up to the point where
the marginal benefit from the activity is equal to the marginal cost.
If the marginal product of labor is falling, is the marginal cost of production rising or falling? Briefly explain. Part 2 If the additional output from each new worker is falling, Part 3
the marginal cost of that output is rising because the only additional cost to producing more output is the additional wages paid to hire more workers.
The late Thomas McCraw of the Harvard Business School once wrote that "when their innovations dwindle, firms begin to die." Source: Thomas K. McCraw, Prophet of Innovation: Joseph Schumpeter and Creative Destruction, Cambridge, MA: Harvard University Press, 2007, p. 181. a. What is an innovation?

If the federal government were to require that employer health care plans have deductibles that were no greater than $200 per year, the employees in these plans would be better off if
the premiums did not increase to offset the lower deductible.
The law of demand is the assertion that
the quantity demanded of a product is inversely related to its price.
A news article on production of oil and natural gas in the Permian Basin of western Texas and New Mexico noted the following two facts: i. "Shale drillers in the Permian Basin are producing vast amounts of gas as a byproduct of prospecting for oil." ii. "Gas prices in parts of the prolific region hovered near zero last month and some trades went negative, to as low as a negative 25 cents per million British thermal units...." Source: Rebecca Elliott, "In Booming Oilfield, Natural Gas Can Be Free," Wall Street Journal, December 27, 2018. a. What does it mean for a price to be negative? A negative 25-cent price means that
the seller has to pay the buyer 25 cents so that the buyer agrees to receive the product.
An increase in the price of a product causes a decrease in quantity demanded because of the income and substitution effects. More specifically,
the substitution effect is the decrease in quantity demanded because the product is more expensive relative to other goods and the income effect is the decrease in quantity demanded owing to the decline in consumers' purchasing power.
When it comes to assessing how this system affects the financial interests of doctors and the well being of consumers, it may be that the former gain more simply because
there are far fewer of them, hence each stands to gain much from supply restrictions.
In an opinion column in the Washington Post, Megan McArdle argued, "In fact, it's debatable whether the other countries' [health care] systems get better outcomes" than the health care system in the United States. Source: Megan McArdle, "What's Really Obstructing Left-Wing Dreams?" Washington Post, May 7, 2018. Part 2 Why is it difficult to measure health outcomes in a way that allows us to determine which country's system provides the best health care? It is difficult to measure outcomes like these because
there is no one statistic that measures outcomes like these.
An article in the Economist on evaluating health care outcomes is subtitled "To Improve Health Care, Governments Need to Use the Right Data." Among the data not currently being collected in most countries, the article mentions "how soon after surgery patients get back to work." Source: "Measuring Health Care," Economist, February 1, 2014. Part 2 Governments do not currently collect such data because
they have no reason to justify the cost of doing so.
Economists assume that people are rational in the sense that
they use all available information as they take actions intended to achieve their goals.
Economists use models (1.3 Economic Models)

William Germano previously served as the vice president and publishing director at the Routledge publishing company. He once gave the following description of how a publisher might deal with an unexpected increase in the cost of publishing a book: "It's often asked why the publisher can't simply raise the price [if costs increase]... It's likely that the editor [is already]... charging as much as the market will bear. ... In other words, you might be willing to pay $50.00 for a ... book on the Brooklyn Bridge, but if... production costs [increase] by 25 percent, you might think $62.50 is too much to pay, though that would be what the publisher needs to charge. And indeed the publisher may determine that $50.00 is this book's ceiling—the most you would pay before deciding to rent a movie instead."

Any cost that changes as output changes represents a firm's A. fixed cost.
variable
Which costs are affected by the level of output produced?
variable costs
The following problem is somewhat advanced. Using symbols, we can write that the marginal product of labor is equal to ΔQ/ΔL. Marginal cost is equal to ΔTC/ΔQ. Because fixed costs by definition don't change, marginal cost is also equal to ΔVC/ΔQ. If Jill Johnson's only variable cost is labor cost, then her variable cost is just the wage times the quantity of workers hired, or w×L. Part 2 If the wage Jill pays is constant, then what is ΔVC in terms of w and L Use your answer above and the expressions given for the marginal product of labor and the marginal cost of output to find an expression for marginal cost, ΔTC/ΔQ, in terms of the wage, w, and the marginal product of labor, ΔQ/ΔL. Part 4 Marginal cost equals Use your answer above to determine Jill's marginal cost of producing pizzas if the wage is $750 per week and the marginal product of labor is 150. The ma

The great baseball player Ty Cobb was known for being very thrifty. Near the end of his life he was interviewed by a reporter who was surprised to find that Cobb used candles, rather than electricity, to light his home. From Ty Cobb's point of view, was the local electric company a monopoly? Part 2 For Cobb, the local electric company
was not a monopoly because candles were a good substitute for electricity.
Explain why the marginal cost curve intersects the average total cost curve at the level of output where average total cost is at a minimum. Part 2 The marginal cost curve intersects the average total cost curve at the level of output where average total cost is at a minimum because
when the marginal cost of the last unit produced is below the average, it pulls the average down, and when the marginal cost is above the average, it pulls the average up.
Refer to the table below. When do diminishing returns in the production of pizzas start?

Some firms offer their employees a health care plan with high deductibles, sometimes as much as $4,500 per year. Part 2 With high-deductible plans, people
will hesitate to go to a doctor to avoid the cost outlay.
If the federal government were to require that employer health care plans have deductibles that were no greater than $200 per year, the employers with these plans would be
worse off because the premium, and their share of the premium, would be higher.
Should Congress and the president be concerned about the growth of Medicare spending?
Yes, since most observers/analysts see unrestrained growth in spending as having the potential to undermine the financial health and stability of the government.
What is the difference between zero accounting profit and zero economic profit?
zero economic profit includes a firm's implicit costs but zero accounting profit does not. Zero economic profit includes a firm's opportunity costs but zero accounting profit does not.
EOG, a Texas-based producer of oil and gas, is called the "Apple of oil" because of the company's history of developing innovative methods to extract energy from shale rock. Using one of EOG's innovations, called iSteer, the company can navigate through thousands of feet of rock with a drill bit that allows for greater recovery of oil and gas than methods the company previously used. Source: Erin Ailworth, "Fracking 2.0: Shale Drillers Pioneer New Ways to Profit in Era of Cheap Oil," Wall Street Journal, March 30, 2017. Briefly explain why economists would consider EOG's use of iSteer an example of technological change.
EOG's use of iSteer enables it to recover more oil and gas with a certain quantity of inputs.
Charles Darrow claimed to have invented and played a game that closely resembles Hasbro's Monopoly game, decades before Hasbro's Monopoly game was introduced. In the legal debate about the right to use the name Monopoly for a game, whether or not Professor Anspach is correct matters because
Hasbro's loss of the trademark on its Monopoly game would have allowed other companies to market similar games using the same title.
Assuming that these statistics are available or could be gathered, are they likely to resolve the normative issues in this debate?

Can we use this information to be certain whether the equilibrium quantity of coconut oil increased or decreased?
No, the change in the equilibrium quantity depends on the relative shifts of demand and supply. If demand shifts more than supply, the equilibrium quantity decreases.
Suppose that competition for software engineers results in Segment.com having to pay them higher salaries. Would the fact that the firm will now face an increased cost of providing its services be an example of negative technological change? Briefly explain.
No, this would not represent technological change because the same output can be produced using the same inputs.
A column by Greg David in Crain's New York Business discussed the effect of rising costs on prices charged by New York City restaurants. David argued that higher costs would result in higher prices and, "at some point, higher prices should reduce demand." Source: Greg David, "New York Area Restaurants Are Hiking Prices," crainsnewyork.com, May 2, 2018. Is he correct that if the price of a product increases, the demand for the product is reduced?
No: an increase in the price of a product will cause a decrease in the quantity demanded of that product, not a decrease in demand.
Sally looks at her college transcript and says to you, "How is this possible? My grade point average (GPA) for this semester's courses is higher than my GPA for last semester's courses, but my cumulative GPA still went down from last semester to this semester."

An article in the New York Times observed, "American doctors often rail against the country's medical malpractice system, which they say forces them to order unnecessary tests and procedures to protect themselves if a patient sues them." Source: Margot Sanger-Katz, "A Fear of Lawsuits Really Does Seem to Result in Extra Medical Tests," New York Times, July 23, 2018. Part 2 Is there another economic explanation—apart from fear of lawsuits—for why doctors may end up ordering unnecessary tests and other medical procedures?
Yes, since doctors themselves largely conduct the tests and perform the procedures, they benefit by enhancing the revenue of their practices.
