Trang 51.1 DEFINITION AND QUESTIONS
! Economics is the study of
A money
B stock market
C the economy
D choice
Trang 61.1 DEFINITION AND QUESTIONS
All economic questions and problems arise because human wants exceed the resources available to satisfy them
! Scarcity
Scarcity is the condition that arises because wants exceeds the ability of resources to satisfy them
Faced with scarcity, we must make choices—we must choose
among the available alternatives
The choices we make depend on the incentives we face
Trang 71.1 DEFINITION AND QUESTIONS
! In economics, scarcity means that:
A A shortage of a particular good will cause the
price to fall
B A production-possibilities curve cannot accurately represent the tradeoff between two goods
C Society's desires exceed the want-satisfying
capability of the resources available to satisfy those desires
D The market mechanism has failed
Trang 81.1 DEFINITION AND QUESTIONS
! Economics Defined
Economics is the social science that studies the choices that individuals, businesses, governments, and entire societies
make as they cope with scarcity, the incentives that influence
those choices, and the arrangements that coordinate them
Two big economic questions:
• How do choices determine what, how, and for whom goods and services get produced?
• When do choices made in self-interest also promote the social interest?
Trang 91.1 DEFINITION AND QUESTIONS
! What, How, and For Whom?
Goods and services are the objects (goods) and actions (services) that people value and produce to satisfy human wants
What goods and services get produced and in what
quantities?
How are goods and services produced?
Trang 101.1 DEFINITION AND QUESTIONS
! When Is the Pursuit of Self-Interest in the
Social Interest?
- The choices that are best for the individual who makes them are choices made in the pursuit of self-interest
(for example: firm’s interest is likely its profit,
consumer’s interest is generally referred to his utility)
- The choices that are best for society as a whole are
choices made in the social interest
Trang 111.1 DEFINITION AND QUESTIONS
Can choices made in self-interest also serve the
social interest?
Trang 121.2 THE ECONOMIC WAY OF THINKING
! Core Economic Ideas:
Trang 131.2 THE ECONOMIC WAY OF THINKING
! Rational Choice
A rational choice is a choice that uses the available
resources to best achieve the objective of the person making the choice
We make rational choices by comparing costs and benefits
Trang 141.2 THE ECONOMIC WAY OF THINKING
! Cost: What You Must Give Up
Opportunity cost is the best thing that you must give up
to get something—the highest-valued alternative forgone
Sunk cost is a previously incurred and irreversible cost
A sunk cost is not part of the opportunity cost of a current
choice
Trang 151.2 THE ECONOMIC WAY OF THINKING
! Benefit: Gain Measured by What You Are Willing
to Give Up
Benefit is the gain or pleasure that something brings.
! On the Margin
A choice made on the margin is a choice made by
comparing all the relevant alternatives systematically and
incrementally
Trang 161.2 THE ECONOMIC WAY OF THINKING
Trang 171.2 THE ECONOMIC WAY OF THINKING
Making a Rational Choice
When we take those actions for which marginal benefit exceeds or equals marginal cost
! Responding to Incentives
An incentive is a reward or a penalty—a “carrot” or a
“stick”—that encourages or discourages an action
Trang 181.2 THE ECONOMIC WAY OF THINKING
! Micro and Macro Views of the World
Microeconomics: The study of the choices that individuals
and businesses make and the way these choices interact and are influenced by governments
Macroeconomics: The study of the aggregate (or total)
effects on the national economy and the global economy of the choices that individuals, businesses, and governments make
Trang 19Players in the economy
Consumers
International participants
Business Firms Governments
Trang 201.2 THE ECONOMIC WAY OF THINKING
! Economics as a Social Science
Economists distinguish between
• Positive statements: What is
• Normative statements: What ought to be
The task of economic science:
To test positive statements about how the economic world works and to weed out those that are wrong
Trang 211.2 THE ECONOMIC WAY OF THINKING
Unscrambling Cause and Effect
The central idea that economists use to unscramble cause and
effect is ceteris paribus
Ceteris paribus means “other things being equal” or “other things remaining the same.”
By changing one factor at a time and holding other relevant factors constant, we are able to investigate the effects of the factor
Trang 22EYE ONS Is wind power
free?
The first wind farm in Vietnam went into
operation is the project
in Binh Thuan province But what would be the cost—the opportunity cost—of that electricity?
Trang 231.3 PRODUCTION POSSIBILITIES
! Production Possibilities Frontier
– The boundary between the combinations of goods and
services that can be produced and the combinations that
cannot be produced, given the available factors of production and the state of technology
– The PPF is a valuable tool for illustrating the effects of
scarcity and its consequences
Trang 24column of the table
The line through the
points is the PPF
1.3 PRODUCTION POSSIBILITIES
Trang 26– The PPF puts three features of production possibilities in
sharp focus:
• Attainable and unattainable combinations
• Efficient and inefficient production
• Tradeoffs and free lunches
Trang 271.3 PRODUCTION POSSIBILITIES
– Because the PPF shows the limits to production, it separates
attainable combinations from unattainable ones
– Figure 3.2 on the next slide illustrates the attainable and
unattainable combinations
Trang 28The PPF separates
attainable combinations
from unattainable
combinations
We cannot produce at any
point outside the PPF
such as point G
We can produce at any
point inside the PPF or on
the frontier
3.1 PRODUCTION POSSIBILITIES
Trang 30– Efficient and Inefficient Production
produce more of one good or service without producing less
of something else
– Figure 3.3 on the next slide illustrates the distinction
between efficient and inefficient production
Trang 31point H, more could be
produced of both goods
without forgoing either
good Production is
inefficient
1.3 PRODUCTION POSSIBILITIES
Trang 33– Tradeoffs and Free Lunches
– A tradeoff is an exchange—giving up one thing to get
something else
– A free lunch is a gift—getting something without giving up something else
– Figure 3.3 on the next slide illustrates the distinction
between a tradeoff and a free lunch
Trang 343 When production is on
the PPF, we face a
tradeoff
4. If production were inside
the PPF, there would be
a free lunch
Moving from point H to
point D does not involve
a tradeoff
1.3 PRODUCTION POSSIBILITIES
Trang 35! A point on a nation's production-possibilities curve represents:
A An undesirable combination of goods and services
B Combinations of production that are unattainable, given current technology and resources
C Levels of production that will cause both
unemployment and inflation
D The full employment of resources to achieve a
particular combination of goods and services
Trang 361.4 OPPORTUNITY COST
! The Opportunity Cost of a Cell Phone
– The opportunity cost of a cell phone is the decrease in the quantity of DVDs divided by the increase in the number of
cell phones as we move along the PPF
– Figure 3.4 illustrates the calculation of the opportunity cost
of a cell phone
Trang 37Moving from A to B, 1 cell phone costs 1 DVD
1.4 OPPORTUNITY COST
Trang 39Moving from B to C, 1 cell phone costs 2

DVDs
1.4 OPPORTUNITY COST
Trang 43– Wind power is not free
– Its opportunity cost includes:
(1) the cost of wind turbines,
(2) the cost of transmission lines, and
(3) power transmission loss
– Wind turbines produce electricity only when there is wind,
which is, at best, 40 percent of the time and, on average, about
25 percent of the time
– Also some of the best wind farm locations are a long way from major population centers, so transmission lines would be long and power transmission losses large
Is Wind Power Free?
EYE on the ENVIRONMENT
Trang 441.4 OPPORTUNITY COST
! Increasing Opportunity Cost
The opportunity cost of a
cell phone increases as
more cell phones are
produced
Trang 461.4 OPPORTUNITY COST
! Slope of the PPF and Opportunity Cost
– The magnitude of the slope of the PPF measures
opportunity cost
– The slope of the PPF in Figure 3.4 measures the opportunity
cost of a cell phone
– The PPF is bowed outward, as more cell phones are
produced, the PPF becomes steeper and the opportunity cost
of a cell phone increases
Trang 471.4 OPPORTUNITY COST
! Opportunity Cost Is a Ratio
– The opportunity cost of a cell phone is the quantity of DVDs forgone divided by the increase in the quantity of cell phones gained
– The opportunity cost of a DVD is the quantity of cell phones forgone divided by the increase in the quantity of DVDs
gained
– When the opportunity cost of a cell phone is x DVDs, the opportunity cost of a DVD is 1/x cell phones
Trang 481.4 OPPORTUNITY COST
! Increasing Opportunity Costs Are Everywhere
– Just about every activity has an increasing opportunity cost
Trang 49If we produce at point
J, we produce only
cell-phone factories and no
remains at 5 million cell
phones every year
1.5 ECONOMIC GROWTH
Trang 501 But if we cut production
Trang 52! Which of the following correctly characterizes the shape of
a production-possibilities curve?
A A straight line indicating the law of increasing opportunity costs applies
B A straight line when there is constant opportunity costs
C A line that curves outward when resources are perfectly adaptable in the production of different goods
D A line that curves inward when resources are perfectly
adaptable in the production of different goods
Trang 53! According to the law of increasing opportunity costs:
A Greater production leads to greater inefficiency
B Greater production means factor prices rise
C Greater production of one good requires
increasingly larger sacrifices of other goods
D Higher opportunity costs induce higher output per unit of input
Trang 551.6 Vietnam Economy: WHAT, HOW, AND FOR WHOM?
! What Do We Produce?
We divide the vast array of goods and services produced into:
• Consumption goods and services
• Capital goods
• Government goods and services
• Export goods and services
Trang 56Consumption goods and services are goods and services
that are bought by individuals and used to provide personal enjoyment and contribute to a person’s standard of living Examples are movies and laundromat services
Capital goods are goods that are bought by businesses to
increase their productive resources
Examples are cranes and trucks
1.6 WHAT, HOW, AND FOR WHOM?
Trang 57Government goods and services are goods and services
that are bought by governments
Examples are missiles, bridges, and police protection
Export goods and services are goods and services
produced in one country and sold in other countries
Examples are Catfish (Tra and Basa) produced by farmers in
An giang sold to US
1.6 WHAT, HOW, AND FOR WHOM?
Trang 58Figure 2.1(a) shows
the relative magnitudes
of the goods and
Trang 601.6 WHAT, HOW, AND FOR WHOM?
Trang 611.6 WHAT, HOW, AND FOR WHOM?
Land
Land includes all the “gifts of nature” that we use to produce
goods and services
Land includes all the things we call natural resources
Land includes minerals, water, air, wild plants, animals, birds, and fish as well as farmland and forests
Trang 621.6 WHAT, HOW, AND FOR WHOM?
Labor
Labor is the work time and work effort that people devote to
producing goods and services
The quality of labor depends on how skilled people are—
what economists call human capital
Human capital is the knowledge and skill that people
obtain from education, on-the-job training, and work
experience
Trang 631.6 WHAT, HOW, AND FOR WHOM?
Capital
Capital consists of 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 semifinished goods, office buildings, and computers
Capital does not include money, stocks, and bonds They are
financial resources
Trang 641.6 WHAT, HOW, AND FOR WHOM?
Entrepreneurship
Entrepreneurship is the human resource that organizes
labor, land, and capital
Entrepreneurs come up with new ideas about what and how to produce, make business decisions, and bear the risks that arise from these decisions
Trang 651.6 WHAT, HOW, AND FOR WHOM?
! For Whom Do We Produce?
Factors of production are paid incomes:
Rent Income paid for the use of land
Profit (or loss) Income earned by an entrepreneur for running a business
Trang 661.6 WHAT, HOW, AND FOR WHOM?
Functional distribution of income is the distribution of income among the factors of production
Personal distribution of income is the distribution of income among households
Trang 671.6 WHAT, HOW, AND FOR WHOM?
Figure 2.2(a) shows the
Trang 691.6 WHAT, HOW, AND FOR WHOM?
Figure 2.2(b) shows the
personal distribution of
income in 2008 ( US and
VN):
The poorest 20% earned
only 3% of total income
(VN: 7.3%)
The richest 20%
earned 51 % of total
income (VN: 45.4%)
Trang 71! The Countries
Advanced Economies
The richest 29 countries (or areas)
Almost 1 billion people (15 percent of the world’s population) live in advanced economies

THE GLOBAL ECONOMY
Trang 72Emerging Market and Developing Economies
Emerging market economies are the 28 countries of Central and Eastern European and Asia
Almost 500 million people live in these countries
Developing economies are the 118 countries in Africa, Asia, the Middle East, Europe, and Central and South America that have not yet achieved high average incomes for their people More than 5 billion people live in these countries

The location of oil,
natural gas, and coal
determines the sources
of the world’s energy
