1. Provide three examples of scarcity that illustrate why even the 1,826
billionaires in the world face scarcity.
The 1,826 billionaires might want to be able to eat unlimited meals with-
out gaining weight; live to be at least 140 years old and enjoy perfect
health everyday; be able to wake up in San Francisco and go to sleep in
Paris after spending no more than 3 hours on a plane. None of these
wants can be fulfilled given the present state of technology and resources
available.
2. Label each entry in the list as dealing with a microeconomic topic or a
macroeconomic topic. Explain your answer.
Motor vehicles production in China is growing by 10 percent a year.
This entry is a microeconomic topic because individuals and businesses
make decisions whether to buy or sell cars.
Coffee prices rocket.
This entry is a microeconomic topic because individuals and businesses

2 Part 1 . INTRODUCTION
Use the following information to work Problems 3 to 6.
Jurassic World had world-wide box office receipts of $1.66 billion. The
movie’s production budget was $150 million with additional marketing costs.
A successful movie brings pleasure to millions, creates work for thousands,
and makes a few people rich.
3. What contribution does a movie like Jurassic World make to coping with
scarcity? When you buy a movie ticket, are you buying a good or a ser-
vice?
Scarcity still exists but the amount of entertainment available in the econ-
omy increases. Buying a ticket to watch a movie is buying a service.
4. Who decides whether a movie is going to be a blockbuster? How do you
think the creation of a blockbuster movie influences what, how, and for
whom goods and services are produced?
The audience decides whether a movie will be a blockbuster because the
audience decides whether to attend the movie.
The “what” question is affected in three ways: First, one good or service
that is produced is the blockbuster movie. Second, the people whose in-
comes are higher as a result of the blockbuster then buy an assortment of
goods and services and so this assortment of goods and services is pro-
duced. Finally, the “what” question is influenced if the movie leads to
spinoff goods (such as toys) or creates a series of sequels or similar films.
The “how” question is affected to the extent that movies use different
production methods. Some movies, for instance, have a lot of special ef-
fects while other movies have few or none. The “for whom” question is
influenced because those people who receive the profits of a blockbuster
movie have higher incomes and so more goods and services are produced
for them.
5. What are some of the components of marginal cost and marginal benefit
that the producer of a movie faces?
Some of the marginal costs the producer faces are the cost of an actor or
actress, the costs of the crew for a day, the costs of a location, and the
costs of advertising in a newspaper. The marginal benefits the producer
enjoys are his or her salary and/or profit participation from the movie,
royalties from the movie, the prestige resulting from a successful movie,
and any awards given to the producer of the movie.
6. Suppose that Chris Pratt had been offered a part in another movie and
that to hire him for Jurassic World, the producer had to double Chris
Pratt’s pay. What incentives would have changed? How might the
changed incentives have changed the choices that people made?
The higher pay would have increased Mr. Pratt’s incentive to make Juras-
sic World rather than the other movie and perhaps affected his choice to

make Jurassic World rather than the other movie. The higher pay would
have increased the incentive of the producer to decrease the expense of
other aspects of the movie so the producer might have chosen to reduce
the pay of the other stars in the movie.
7. What is the social interest? Distinguish it from self-interest. In your
answer give an example of self-interest and an example of social interest.
The social interest looks at what is best for society as a whole; choices that
are best for society as a whole are said to be in the social interest. The self-
interest looks at what is best for the individual; choices that are best for
the individual making the choice are said to be in the self-interest. An ex-
ample of a choice made in the self-interest is a student’s decision to take
an economics class. An example of a choice made in the social interest is a
firm’s decision to reduce its air pollution.
8. Pam, Pru, and Pat are deciding how they will celebrate the New Year.
Pam prefers to take a cruise, is happy to go to Hawaii, but does not want
to go skiing. Pru prefers to go skiing, is happy to go to Hawaii, but does
not want to take a cruise. Pat prefers to go to Hawaii or to take a cruise
but does not want to go skiing. Their decision is to go to Hawaii. Is this
decision rational? What is the opportunity cost of the trip to Hawaii for
each of them? What is the benefit that each gets?
Pam, Pru and Pat’s decision to go to Hawaii is rational. All three of them
considered the cost and benefit of various New Year’s plans. All three
were at least willing to go to Hawaii while Pam and Pat were unwilling to
go skiing and Pru was unwilling to go on a cruise. The opportunity cost
of the trip for Pam is a cruise; for Pru, it is skiing; and for Pat, it is a cruise.
The benefit each receives is the pleasure, the relaxation, excitement,
and/or knowledge gained from the trip.

REI is paying its employees to take Black Friday, Thanksgiving off
REI, the outdoor gear and apparel retailer, is paying employees to celebrate
Thanksgiving 2015 by spending Black Friday outdoors with their families.
Source: Sustainable Brands, October 28, 2015
10. With Black Friday off with full pay, explain what is free and what is
scarce.
The workers’ time remains scarce because Black Friday remains only one
day. REI’s gear and apparel remain scarce because there is a still a limited
amount of these products. The publicity that REI received is not free be-
cause the company paid for it with less production and, accordingly, less
revenue and profit.
11. What is REI’s incentive to give its workers Black Friday off? Was REI’s
decision made in self-interest or in the social interest? Explain your an-
swer.
REI’s managers have the incentive to give their employees the day off if
they believe that the positive publicity that resulted could lead to in-
creased future sales. The managers might also believe that the employees
would feel grateful and would worker harder in the future. Of course, the
managers also had the incentive to give their workers the day off because
many other employers do so.
REI’s decision to give its workers a paid day off had elements of both self-
interest and social interest. To the extent that his decision was motivated
by the free publicity and a resulting rise in sales, or the expectation that its
employees would work more diligently in the future, the decision was
motivated by self-interest. However, to the extent that a desire to allow
the workers a chance to spend time with their families, the decision also
had elements of social interest.
12. Do you think that REI workers will shop or spend the day with family?
Explain your answer.
Some REI workers will shop and others will spend the day with their
family, depending on which alternative is in their self-interest.
13. Read Eye on the Benefit and Cost of School on p. 12 and explain why both
you and Clayton Kershaw made the right decision.
Clayton Kershaw made the correct decision to skip college because the
opportunity cost to him of attending college (which includes his forgone
salary playing baseball) vastly exceeded the benefits to him of attending
college. For most students, the opportunity cost of attending college is not
so large, so for most students the benefits from attending college exceed
the opportunity cost of attendance. For these students, attending college is
the correct decision.

Instructor Assignable Problems and Applications
1. Which of the following are components of the opportunity cost of being a
full-time student who lives at home? The things that the student would
have bought with:
A higher income
The items the student would have purchased with the higher income he
or she would have earned if he or she was not a full-time student are an
opportunity cost of being a full-time student.
Expenditure on tuition
The cost of tuition is part of the opportunity cost of being a full-time
student because this expense is paid only because the person is a stu-
dent.
A subscription to the Rolling Stone magazine
If the subscription was required by a class and the individual sub-
scribed only because of the class requirement, then the cost of the sub-
scription is an opportunity cost of being a student. However if the per-
son would have subscribed to Rolling Stone even if he or she was not a
student, then the cost of the subscription is not an opportunity cost of
being a student.
The income a student will earn after graduating
The income earned after graduation is not an opportunity cost of being
a student.
2. Think about the following news items and label each as involving a
what, how, or for whom question:
Today, most stores use computers to keep their inventory records,
whereas 20 years ago most stores used paper records.
Stores using computers for inventory records today versus paper 20
years ago answers the how question.
Healthcare professionals and drug companies recommend that Medi-
caid drug rebates be made available to everyone in need.
Deciding whether to offer lower Medicaid drug rebates, which would
lower the prices for drugs, is a for whom question.
An increase in the gas tax pays for low-cost public transit.
Building a low-cost public transit system answers a what question. Be-
cause not everyone will use the public transportation equally nor will
everyone pay the same amount of taxes, there also is a for whom aspect
of the headline.

a macroeconomic topic. Explain your answers.
Job Gains Calm Slump Worries
This entry is a macroeconomic topic because the slump concerns a
turndown in the overall economy and neither an individual nor a busi-
ness makes the decision to slow the aggregate economy.
Washington Post’s Profit Falls
This entry is a microeconomic topic because it concerns the profit out-
come of one business, the Washington Post.
Overcapacity, Fuel Costs Hit Shipping
This entry is a microeconomic topic. It describes the situation within
one sector—shipping—which is being affected by overcapacity and a
rise in the price of fuel.
U.S. Budget Deficit Expands
This entry is a macroeconomic topic because the budget deficit is the re-
sult of taxes and government spending spread over all sectors in the en-
tire economy.
4. Your school decides to increase the intake of new students next year. To
make its decision, what economic concepts would it have considered?
Would the school have used the “economic way of thinking” in reaching
its decision? Would the school have made its decision on the margin?
The school would consider the extra revenue that each additional student
would bring and compare that to the extra cost of providing each student
with instruction and service. By comparing the extra revenue and the ex-
tra cost, the school is making its decision on the margin and is using the
economic way of thinking. If the school compares the additional revenue
to the additional cost, it makes its decision on the margin.
5. Provide examples of (a) a monetary incentive and (b) a non-monetary
incentive, a carrot and a stick of each, that government policies use to in-
fluence behavior.
(a) A monetary carrot that the students might answer because it is close
to their lives is student aid, such as Pell grants. A monetary stick
might be taxes on liquor.
(b) A non-monetary carrot is government support for youth sports, such
as allowing little league teams to use a county park, and a non-
monetary stick is jail terms for illegal drug or alcohol use.

incentives and might change the choices that people make:

The hurricane affects the people in Central Florida and the consumers
who purchase the products produced in Central Florida, such as orang-
a macroeconomic topic. Explain your answers.
Job Gains Calm Slump Worries
This entry is a macroeconomic topic because the slump concerns a
turndown in the overall economy and neither an individual nor a busi-
ness makes the decision to slow the aggregate economy.
Washington Post’s Profit Falls
This entry is a microeconomic topic because it concerns the profit out-
come of one business, the Washington Post.
Overcapacity, Fuel Costs Hit Shipping
This entry is a microeconomic topic. It describes the situation within
one sector—shipping—which is being affected by overcapacity and a
rise in the price of fuel.
U.S. Budget Deficit Expands
This entry is a macroeconomic topic because the budget deficit is the re-
sult of taxes and government spending spread over all sectors in the en-
tire economy.
4. Your school decides to increase the intake of new students next year. To
make its decision, what economic concepts would it have considered?
Would the school have used the “economic way of thinking” in reaching
its decision? Would the school have made its decision on the margin?
The school would consider the extra revenue that each additional student
would bring and compare that to the extra cost of providing each student
with instruction and service. By comparing the extra revenue and the ex-
tra cost, the school is making its decision on the margin and is using the
economic way of thinking. If the school compares the additional revenue
to the additional cost, it makes its decision on the margin.
5. Provide examples of (a) a monetary incentive and (b) a non-monetary
incentive, a carrot and a stick of each, that government policies use to in-
fluence behavior.
(a) A monetary carrot that the students might answer because it is close
to their lives is student aid, such as Pell grants. A monetary stick
might be taxes on liquor.
(b) A non-monetary carrot is government support for youth sports, such
as allowing little league teams to use a county park, and a non-
monetary stick is jail terms for illegal drug or alcohol use.

es or vacation services. Residents’ incentives change if they suffered
damage from the hurricane because they have the incentive to repair
the damage. If the price of home repair rises, residents who specialize in
home repair have an incentive to work longer hours to earn the higher
price. If the hurricane raises the price of the goods and services pro-
duced in Central Florida, consumers have the incentive to buy less of
these particular goods and services because they are more expensive.
The World Series begins tonight but a storm warning is in effect for
the area around the stadium.
The report of the possible storm decreases fans’ incentive to attend the
game. Some fans decide to stay at home and watch the game on television.
The price of a personal computer falls to $50.
The fall in the price of a computer increases consumers’ incentive to buy
a computer. More consumers decide to buy a computer. The fall in the
price of a computer decreases producers’ incentives to produce com-
puters. Fewer producers decide to produce computers.
Unrest in the Middle East sends the price of gas to $5 a gallon.
The rise in the price of gasoline affects drivers’ incentives to buy gaso-
line and large gas-guzzling cars. Drivers decide to buy less gasoline and
fewer large gas-guzzling cars. They also might decide to ride public
transportation more often.
7. Does the decision to make a blockbuster movie mean that some other
more desirable activities get fewer resources than they deserve? Is your
answer positive or normative? Explain your answer.
Making a blockbuster movie means that some other activities get fewer
resources. But whether “more desirable” activities get fewer resources
than they “deserve” is a normative answer for two reasons. First the ques-
tion of whether an activity is more desirable or less desirable depends on
the person’s judgment and values. Second the determination of whether
an activity gets fewer resources than it deserves also involves the norma-
tive decision about the quantity of resources an activity deserves. So the
answer to the question of whether making a blockbuster movie means
that other more desirable activities get fewer resources than they deserve
is a normative answer that depends on the student’s values.

(b) a business, and (c) a government. Classify your examples as dealing

Obama unveils major climate change policy
Obama’s Clean Power Plan, which will set federal limits on carbon emissions
from coal-fired power plants, will cost $8.4 billion and reap benefits of more
than $34 billion. Opponents of the plan say it will drive up the cost of elec-
tricity for millions of Americans.

9. What are the more than $34 billion of benefits from using less coal to
produce electricity? Who receives these benefits: the users of electricity or
the owners of power plants, or both the users and the owners?
Benefits include: (1) a reduction in carbon emissions, which brings a de-
crease in the contribution of human activity to global warming and cli-
mate change, and (2) cleaner air, which contributes to improved health.
Both the users of electricity and the owners of power plants receive the
benefits.
10. What are the $8.4 billion of costs arising from using less coal to produce
electricity? Who bears these costs: the users of electricity or the owners of
power plants, or both the users and the owners?
To decrease carbon emissions from coal-fired plants requires that the
plants install more pollution abatement equipment, such as scrubbers on
their stacks that decrease emissions of carbon. The costs of the equipment
and its installation account for the costs of the Clean Power Plan. Users of
electricity, who pay higher prices for electricity, will pay some of these
costs and owners of power plants, who receive lower profits from produc-
ing electricity, also will pay some of the costs.
11. Explain why someone might oppose the Clean Power Plan when its
benefits exceed its costs.
Someone might oppose the Clean Power Plan because he or she believes
that the benefits and costs are measured incorrectly so that in reality the
costs exceed the benefits. Others might oppose it because the costs that
fall on them exceed the benefits that they receive.
12. Explain whether the Clean Power Plan has an opportunity cost.
The Clean Power Plan has an opportunity cost because the resources de-
voted to meeting its goals and requirements could be used instead to pro-
ducing other goods and services.
(b) A business uses economics as a tool when it decides the price it

Is the relationship between x and y positive or negative? Calculate the
slope of the relationship when x equals 2 and when x equals 4. How does
the slope change as the value of x increases?
The relationship is negative: When x increases, y decreases. The slope of
the relationship equals the change in y divided by the change in x along
the tangent line; that is, the slope of the relationship at a point equals the
slope of the tangent line at that point. When x equals 2, the slope of the
tangent line equals –4, so the slope of the relationship equals –4. When x
equals 4, the slope of the tangent line equals –8, so the slope of the rela-
tionship equals –8. The slope of the relationship increases in magnitude
(the line becomes steeper) as x increases.

sheet.
a. The quantity sold was the highest in 2006.
b. The quantity sold was the lowest in 2014.
c. The quantity sold decreased the most be-
tween 2004 and 2006 and between 2006 and
2008, when it decreased by 10 million per
period.
d. Setting aside the periods during which the
quantity increased, the quantity sold de-
creased the least between 2008 and 2010.
There is a downward trend in the quantity of music videos sold.
Use the following data on the relationship between two variables x and y to
work Problems 3 and 4.
x 0 1 2 3 4 5
y 0 1 4 9 16 25
3. Is the relationship between x and y positive or negative? Explain.
The relationship is positive: When x increases, y also increases.
4. Calculate the slope of the relationship when x equals 2 and x equals 4.
How does the slope change as the value of x increases?
The slope of the relationship equals the change in y divided by the change
in x along the tangent line; that is, the slope of the relationship at a point
equals the slope of the tangent line at that point. When x equals 2, the
slope of the tangent line equals 4, so the slope of the relationship equals 4.
When x equals 4, the slope of the tangent line equals 8, so the slope of the
relationship equals 8. The slope of the relationship increases as x increas-
es.

4. Which factor of production earns the highest percentage of total U.S. in-
come? Define that factor of production. What is the income earned by
this factor of production called?
Labor earns by far the largest percentage of total U.S. income, 63 percent
of total income in 2014. Labor consists of the work time and the work ef-
fort that people devote to producing goods and services. The income
earned by labor is a wage.
5. With more job training and more scholarships to poor American stu-
dents, which special factor of production is likely to grow faster than in
the past?
As more people go to school and/or receive job training, the nation’s hu-
man capital will grow more rapidly. Human capital is the knowledge and
skills people obtain from education, on-the-job training, and work experi-
ence. With more job training and more scholarships, human capital will
grow more rapidly.
6. Define the factor of production called capital. Give three examples of
capital, different from those in the chapter. Distinguish between the fac-
tor of production capital and financial capital.
Capital is the tools, instruments, machines, buildings, and other items that
have been produced in the past and that businesses now use to produce
goods and services. Capital includes railroad engines and cars, servers,
and ATMs. The factor of production “capital” is the actual good itself; “fi-
nancial capital,” such as stocks and bonds, are the funds that provide
businesses with their financial resources which can be used to acquire
capital goods.

whom goods and services are produced in the United States
The answer to the what question changes if, as is probably the case, new
and young business produce different goods and services than more es-
tablished business. For example, new and young firms are more likely to
create apps than older and more established firms. If these groups of pro-
ducers produced their goods and services using different technologies
than the rest of the producers, then the question of how goods and ser-
vices would change. For whom goods and services are produced would

9. Why you can get a free college education in Germany but not in California
Even American students can get a free college degree in Germany, where
high taxes pay for colleges. Despite college being free, fewer students in
Germany earn college degrees than in the United States and more enter
vocational apprenticeships.
Source: Los Angeles Times, October 29, 2015
If California adopted the German model of higher education, how
would that change for whom goods and services are produced?
The students in California who otherwise would not have gone to col-
lege but who take advantage of the “free” college education will have
higher incomes than otherwise. Consequently, more goods and ser-
vices will be produced for them. The taxpayers who must pay the
taxes necessary to fund these college educations will have less income
to spend on goods and services, so fewer goods and services will be
produced for them.
10. Read Eye on the Dreamliner on p. 43 and then answer the following ques-

How many firms are involved in the production of the Dreamliner

Over 400 firms are involved in the production of the Dreamliner. On-
ly 15 of them are identified in the figure.
Is the Dreamliner a capital good or a consumption good? Explain
why?
The Dreamliner is a capital good because it will be used to produce
services (airline travel) throughout many future years.
State the factors of production that make the Dreamliner and provide
an example of each.
All the factors of production—land, labor, capital, and entrepreneur-
ship—are used to make the Dreamliner. The copper used for wiring is
an example of the land used; the engineer who helped design the
landing gear is an example of labor; the huge cranes that lift the vari-
ous pieces of the Dreamliner to assemble them is an example of capi-
tal; and the creative and imaginative input of Boeing’s top managers
who organize the resources used to produce the Dreamliner exempli-

Instructor Assignable Problems and Applications
1. Boeing’s Dreamliner has had a rocky start.
Why doesn’t Boeing manufacture all the components of the Dream-
liner at its own factory in the United States?
Boeing wants to manufacture the Dreamliner at the lowest possible
cost. It would be more expensive for Boeing to manufacture Dream-
liners at its own factory in the United States because Boeing does not
have the expertise possessed by its subcontractors and because the
wages Boeing pays U.S. workers exceed the wages its subcontractors
pays their workers.
Describe some of the changes in what, how, and for whom, that
would occur if Boeing manufactured all the components of the
Dreamliner at its own factories in the United States.
If Boeing manufactured all the components of the Dreamliner at its
own factories in the United States, more components would be pro-
duced in the United States and more capital would have been used in
their production.
U.S. workers and investors would have received higher incomes but
the Dreamliner would cost more to produce so Boeing would have
earned a lower profit.
State some of the tradeoffs that Boeing faces in making the Dream-
liner.
Boeing faced a huge number of tradeoffs. For example, when design-
ing the plane, Boeing’s engineers had to make decisions about fuel
economy and passenger load. Increasing the passenger load de-
creased fuel economy, so the engineers traded passenger load for fuel
economy. Another example revolves around the construction of the
Dreamliner. Boeing could have constructed the plane using just a few
companies but instead it used over 400. Boeing was trading off the
simplicity of dealing with just a handful of companies for the in-
creased specialization by dealing with many specialized companies.
Why might Boeing’s decisions in making the Dreamliner be in the
social interest?
Building the Dreamliner itself advances the social interest because it
increases the quantity of comfortable, rapid transportation. The
amount of high-quality transportation available in the economy in-
creases, which benefits society. The decisions in making the Dream-
liner advance the social interest because they were designed to make
the Dreamliner at low cost and thereby avoid wasting resources.

ca, 33 percent have a smartphone. Describe the changes in what, how, and
for whom telecommunication services are produced in the global economy.
What: As the number of cell phone users increases, the global economy
has been producing more cell phone telecommunication services. More
cell phones are produced, fewer land phones are produced, and presum-
ably more cell phone frequencies are used.
How: More telecommunication services are being produced using cell
phones rather than fixed-line phones.

7. China’s income gap widens
The income gap has widened in China. In 2014, the pay of workers in the
coastal regions increased by 9.7 percent while that of workers in the in-
land regions grew by 9 percent.
Source: South China Morning Post, May 28, 2015
Explain how the distribution of personal income in China can be getting
more unequal even though the poorest are getting richer.
The distribution of income in China can be getting more unequal even
when the poorest are getting richer if the richest are getting richer even
faster. If the rich are getting richer faster, the fraction of the nation’s total
income received by the poorest 20 percent falls, which makes the personal
distribution of income more unequal.
8. Compare the scale of agricultural production in the advanced and devel-
oping economies. In which is the percentage higher? In which is the total
amount produced greater?
Agricultural is a small part of total production in advanced economies. It
is a much larger part in developing economies. Even though advanced
economies devote only a small part of their total production to agricul-
ture, they still produce about one third of the world’s total production of
food. The remaining two thirds is produced in the developing nations.

oping economies. In which is the percentage higher? In which is the total
amount produced greater?
Agricultural is a small part of total production in advanced economies. It
is a much larger part in developing economies. Even though advanced
economies devote only a small part of their total production to agricul-
ture, they still produce about one third of the world’s total production of
food. The remaining two thirds is produced in the developing nations.

Poor India makes millionaires at fastest pace
India, with the world’s largest population of poor people, also paradoxically
created millionaires at the fastest pace in the world. Millionaires increased by
22.7 percent to 123,000. In contrast, the number of Indians living on less than a
dollar a day is 350 million and those living on less than $2 a day is 700 million.
In other words, there are 7,000 very poor Indians for every millionaire.

10. How is the personal distribution of income in India changing?
If the number of millionaires is growing more rapidly than the number of
other income groups, it will be the case that the personal distribution of
income in India is becoming less equally distributed.
11. Why might incomes of $1 a day and $2 a day underestimate the value of
the goods and services that these households actually consume?
The people living on $1 and $2 a day probably grow a lot of their food
and produce a lot of their clothing and shelter. If these goods and services
are not taken into account, their share of goods and services is understat-
ed. Including them raises the value of the goods and services these
households actually consume.

Use the following information to work Problems 2 and 3.
The people of Leisure Island have 50 hours of
labor a day that can be used to produce enter-
tainment and good food. The table shows the
maximum quantity of either entertainment or
good food that Leisure Island can produce
with different quantities of labor.
2. Is an output of 50 units of entertainment
and 50 units of good food attainable and efficient? With a production of
50 units of entertainment and 50 units of good food, do the people of
Leisure Island face a tradeoff?
Producing 50 units of good food and 50 units of entertainment is attaina-
ble. However, at this production point, Leisure Island’s resources are not
fully employed or are misallocated. They are producing within their PPF.
As a result, the people of Leisure Island do not face a tradeoff—they can
produce more entertainment or good food at no opportunity cost.
3. What is the opportunity cost of producing an additional unit of enter-
tainment? Explain how the opportunity cost of producing a unit of enter-
tainment changes as more entertainment is produced.
If production is initially within the PPF, the opportunity cost of an addi-
tional unit of entertainment is zero. If production is on the PPF there is an
opportunity cost of producing a unit of entertainment because good food
must be forgone. At that point, the opportunity cost while moving along
the PPF equals the loss in good food produced divided by the gain in en-
tertainment produced. Once on the PPF, as more entertainment is pro-
duced, the opportunity cost of an additional unit increases.
Use the following information to work Problems 4 and 5.
Malaria can be controlled
The World Health Organization’s malaria chief says that it is too costly to try
to fully eradicate the disease. He says that by using nets, medicine, and DDT
it is possible to eliminate 90 percent of malaria cases. But to eliminate 100
percent of cases would be extremely costly.
