The Fundamental Economic Problem
 Our wants exceed our capacity for satisfying those
wants.
 Economic resources are scarce, wants and needs (uses for
those resources) are unlimited.
 Economic Resources:
 Land – Nature-made (soil, trees, water, animals)
 Labor – Human effort (workers)
 Capital – Goods used for producing other goods (machines, tools,
factories)
 Enterprise – Managerial function that coordinates other
resources (business owners, risk takers)
The Fundamental Economic Problem
Economics defined:
Study of how to use our
limited resources to satisfy our
unlimited wants and needs
as fully as possible.

The Fundamental Economic Problem
Economic Models :
 Microeconomics
Study of individual economic decision makers, small
units that make up the whole (consumers, firms,
government).
 Macroeconomics
Study of the economy’s overall performance,
outcomes of the micro decisions (state, national,
international).
Economic Systems, briefly…
 Economic system – set of institutions and mechanisms
for answering the three fundamental questions of
economics – what, how, and for whom.
We will discuss Economic systems in detail later in
the unit; this is helpful to know for now!
Class Activity  What should be on your desk?
 NOTHING! – clear it all off…you don’t even need a
pen, pencil, or writing utensil!
 Where should you be ?
 Gathered in groups of SIX.

Economics and Resources
 Scarcity – occurs whenever we do not have enough resources
to produce all the things we would like to have.
 Resources – the things used in making goods or providing
services.
 They include:
 Tools
 Natural resources such as wood, soil, and water.
 Human Resources – people who provide the necessary
labor and skills.
 Can any of these last forever?
They are limited.
Renewable/ Nonrenewable Resources –
How would we categorize….
The Three Fundamental Economic Questions
 What to Produce
What goods and services will our economy produce, and in
what quantities?
 How to Produce
How will these goods and services be produced? What
materials and methods will we use? More labor intensive or
capital intensive? Will we ship by truck, train or boat?
 For Whom to Produce
For whom will these goods and services be produced, and how
will we distribute them? Divide equally? Should those who
produce more receive more? First come first served?
Essential Question:
 What factors influence producers to increase or
decrease output?
 What factors influence consumers to increase or
decrease the consumption of goods?

 Marginal Benefit
 Cost-Benefit Analysis

Cost Benefit Analysis (CBA)
 Individuals, businesses, and governments engage in
systematic comparisons of costs and benefits in order
to decide a course of action.
 Often costs and benefits can be subjective, difficult to
measure, incomparable, or hidden.
 How do we measure a human life? Should humans be
valued differently? If so, by what criteria?
 How much is the last spotted owl worth? What is the cost
of letting it die? Is that cost the same for everyone?
 What are the benefits of making consumption of tobacco
illegal? What are the costs?
Cost Benefit Analysis (CBA)
“There’s no such thing
as a free lunch.”
Milton Friedman
Nobel Laureate, Economics, 1976
(1912 - 2006)
 Everything has an economic cost! Yes, EVERYthing.
 When you decide to do or have one thing, you give up the
opportunity to do or have something else.
 Opportunity cost – the next most highly valued alternative you
must sacrifice in order to take a particular action.
Cost Benefit Analysis (CBA)
 Opportunity cost – the next most highly valued alternative you
must sacrifice in order to take a particular action.
 The opportunity cost of military spending = the government
program that would have been funded if military spending did
not increase.
 Opportunity costs MUST be included in cost benefit analysis.
 What would you be doing if you weren’t in class today?
 Upon graduation, you get a $75k/yr job offer. What is the
opportunity cost of going to college instead?
Five Economic Goals
1) Full employment of economic resources
When resources are not fully employed, society is sacrificing
goods and services that could have been produced.
2) Efficiency
Economic efficiency means getting the most benefit out of
limited resources. Goods and services that society wants and
needs the most should be produced with as few resources as
possible.
3) Economic growth
Economic growth is expansion of the economy’s capacity to
produce, providing more goods and services. This is necessary
for standard of living to increase over time.
Five Economic Goals
4) Fair distribution of income
How will income be divided among members of society? In
modern economies, distribution of income determines how
output will be shared or divided. Should higher incomes get a
larger share of output, or should it be divided equally? Should
income be redistributed until there is no poverty?
5) Stable price level
Societies fear inflation (rise in average prices). Inflation
redistributes incomes randomly. Those whose incomes rise
faster than inflation will get a larger share of output than
those whose incomes rise more slowly.
Conflicts and Trade-offs
Trade-off – the alternative you face if you
decide to do one thing over another
 Full employment vs. Stable Prices
 Economic Growth vs. Environmental Protection
 Equality vs. Efficiency
Essential Question:
 What factors influence producers to increase or
decrease output?
 What factors influence consumers to increase or
decrease the consumption of goods?

Costs and Decision Making
Marginal Analysis
 Using marginal benefits and marginal costs to make a
decision.
 Marginal = additional, or extra
 Marginal costs and marginal benefits are the relevant costs
and benefits to compare.
 Marginal costs (MC) = additional costs of doing (producing,
consuming, buying) something.
 Marginal benefits (MB) = additional benefits of doing (producing,
consuming, buying) something.
 If MB > MC, do it. If MB < MC, don’t do it. Keep doing it til MB=MC.
 Maximum utility, maximum profit, can be found where MB = MC
Measuring Total Output
 GDP, or gross domestic product, is the market
value of all final goods and services produced
in a country in a given time period.
 US GDP, 2nd quarter 2008 ($ billions) :
Nominal GDP
Real GDP
$14,312.5
$11,740.3
(+2.2%)
 US GDP, 1st quarter 2009 ($ billions) :
Nominal GDP
Real GDP
Source: BEA.gov
$14,097.2
$11,360.5
(–2.5%)
Measuring Total Output
GDP measures production within a nation’s
borders – domestic production – no matter who
owns the resources.
 Cars produced in a Japanese-owned factory in the
US counts in US GDP.
 Cars produced in a US-owned factory in Mexico
counts in Mexico’s GDP.
Essential Question:
 What factors influence producers to increase or
decrease output?
 What factors influence consumers to increase or
decrease the consumption of goods?

Standard of Living
The quality of life based on the possession of
necessities and luxuries that make life easier.
 What is a necessity of life?
 What is a luxury?
 Are these the same for everybody? The majority?
 Is there a right to work? To own a home? To get
equal pay for equal work?
Defining an Economic System
 Economic system – set of institutions and mechanisms
for answering the three fundamental questions of
economics – what, how, and for whom.
 Two Questions to Ask:
 Who owns the means of production used to produce goods
and services?
 Who makes the economic decisions? (who answers the 3
fundamental questions?)
Defining an Economic System
 All economic systems combine elements of two models at the
extremes of a continuum:
Question
Who owns the
means of
production?
Who makes the
economic
decisions?
Pure Capitalism
Pure Command
Socialism
Resources are privately Resources are
owned
publicly owned
(owned by the state)
Buyers and Sellers
Central planning
interacting in markets authority
The Model of Pure Capitalism
 Elements of Capitalism :
Are these things true of the US economy?
1) Private Property & Freedom of Choice
 Private owners of means of production can
choose how they sell or use their resources
(labor, machinery, raw materials, farms, etc).
 Firms can decide freely what they will produce
and from whom to purchase the necessary
resources.
 Consumers are free to spend or save their income
however they choose.
The Model of Pure Capitalism
 Elements of Capitalism:
Are these things true of the US economy?
2) Self-Interest
 Adam Smith (Wealth of Nations, 1776) described a
capitalist economy as one in which the primary
concern of each player (producer, consumer, worker) was
to promote his or her own welfare.
 Smith’s “invisible hand” doctrine said that as
individuals pursue their own interests, they would
be led by an invisible hand to promote the good
of society as a whole.
The Model of Pure Capitalism
 Elements of Capitalism:
Are these things true of the US economy?
2) Self-Interest (cont.)
 To maximize profits, producers generate products
consumers want most.
 To earn higher wages, workers offer their services
where they are most needed.
 To maximize buying power, consumers favor producers
offering superior products at fair prices.
 The result? An economy that produced goods and
services desired by society, with no need for central
government direction.
The Model of Pure Capitalism
 Elements of Capitalism:
Are these things true of the US economy?
3) Markets and Prices
 Economic activity coordinated through markets
(interaction of buyers and sellers of a good or service).
 Markets determine prices, which serve two
important functions:
i.
ii.
To divide up, or ration, goods and services. Only
those willing and able to pay the price will receive
the product.
To motivate firms to produce more of some things
and less of others.
The Model of Pure Capitalism
 Elements of Capitalism:
Are these things true of the US economy?
4) Competition
 For Smith’s invisible hand to work, pursuit of selfinterest must be guided and restrained by
competition.
 Pure competition – large number of relatively small
buyers and sellers interact to determine prices.
 No individual buyer and seller is powerful enough to
have influence over price.
 Market prices MUST be determined by market forces,
not powerful buyers or sellers.
The Model of Pure Capitalism
 Elements of Capitalism:
Are these things true of the US economy?
5) Limited Government Intervention
 Pure capitalism is a laissez-faire (roughly translated, “let
the people choose”) economy.
 Not the role of government to answer
fundamental questions (what, how, for whom).
 Role of government is to ensure environment
where market can function.
 Must define and enforce private property rights,
and provide means of arbitration and penalties
(laws, courts and prisons).
How Capitalism Answers the 3 Questions
1) What to Produce
 Consumer Sovereignty – economic condition in which
consumers dictate which goods and services firms
will produce.
 Firms are motivated by profits. The most profitable
products tend to be those desired most by
consumers, so firms must be responsive to consumer
preferences.
“The consumer, so it is said, is the king...
each is a voter who uses his money as votes
to get the things done that he wants done.”
Paul Samuelson
Nobel Laureate, Economics, 1970
(1915 - )
How Capitalism Answers the 3 Questions
2) How to Produce
 Many goods and services can be produced using
alternative methods and materials – steel or
fiberglass, machine or human, computer or pencil
and paper, telephone or internet, brick or wood,
skilled labor or unskilled labor.
 Capitalist producers will tend to select the leastcost approach to maximize profits.
How Capitalism Answers the 3 Questions
3) For Whom to Produce
 In a capitalist economy, goods and services will be
distributed to those with:
a) The ability to pay, and
b) The willingness to pay
 A consumer may be able to buy a particular good, but
will choose not to, or to consume something else instead.
 In general, those with higher incomes will always have
more choices than those with lower incomes, and will
receive a larger share of the economy’s total output.
