What is Economics?
Economics is the study of _________.
• Economics is the science of scarcity.
• Scarcity means that we have unlimited wants
but limited resources.
• Since we are unable to have everything we
desire, we must make choices on how we will
use our resources.
choices
In economics we will study the choices of
individuals, firms, and governments.

Textbook Definition Economics- Social science concerned with the
efficient use of scarce resources to achieve
maximum satisfaction of economic wants.
(Study of how individuals and societies deal
with ________)
Examples:
You must choose between buying jeans or buying shoes.
Businesses must choose how many people to hire
Governments must choose how much to spend on
welfare.

Micro vs. Macro
MICROeconomics- Study of small economic units such as
individuals, firms, and industries (ex: supply
and demand in specific markets, production
costs, labor markets, etc.)
MACROeconomics- Study of the large economy as a whole or
economic aggregates (ex: economic growth,
government spending, inflation,
unemployment, international trade etc.)

Positive vs. Normative Positive Statements- Based on facts. Avoids value
judgements (what is).
Normative Statements- Includes value judgements
(what ought to be).
How is Economics used?
• Economists use the scientific method to make
generalizations and abstractions to develop
theories. This is called theoretical economics.
• These theories are then applied to fix problems
or meet economic goals. This is called policy
economics.

5 Key Economic Assumptions 1. Society’s wants are unlimited, but ALL resources
are limited (scarcity).
2. Due to scarcity, choices must be made. Every choice
has a cost (a trade-off).
3. Everyone’s goal is to make choices that maximize
their satisfaction. Everyone acts in their own “self-
interest.”
4. Everyone makes decisions by comparing the
marginal costs and marginal benefits of every
choice.
5. Real-life situations can be explained and analyzed
through simplified models and graphs.

Would you see the movie three times?
Notice that the total benefit is more than the
total cost but you would NOT watch the movie
the 3rd time.
Thinking at the Margin
# Times
Watching Movie Benefit Cost
1st $30 $10
2nd $15 $10
3rd $5 $10
Total $50 $30

Marginal Analysis In economics the term marginal = additional Marginal analysis (aka: thinking on the margin)
making decisions based on increments Example: • When you decide to go to the mall you consider the
additional benefit and the additional cost (your opportunity cost).
• Once you get to the mall, you continue to use marginal analysis when you shop, buy food, and talk to friends.
• Since your marginal benefits and costs can quickly change your analyzing them every second.
• What if your ex-girlfriend shows up?
The Point: You will continue to do something as long as
the marginal benefit is greater than the marginal cost 13

Given the following assumptions, make a rational
choice in your own self-interest (hold everything
else constant)…
1. You want to visit your friend for a week. You will return Sunday night.
2. You work every weekday earning $100 per day
3. You have three flights to choose from:
Thursday Night Flight = $275
Friday Early Morning Flight = $300
Friday Night Flight = $325
Which flight should you choose? Why? 19

Trade-offs vs. Opportunity Cost ALL decisions involve trade-offs.
Opportunity cost- most desirable alternative
given up when you make a choice. .
Trade-offs - ALL the alternatives that
we give up when we make a choice (Examples: going to the movies)
What are trade-offs of deciding to go to college?
What is the opportunity cost of going to college?
GEICO assumes you understand
opportunity cost. Why? 20

Guns and Butter "Every gun that is made, every warship launched, every
rocket fired signifies, in the final sense, a theft from those
who hunger and are not fed, those who are cold and are not
clothed. This world in arms is not spending money alone. It
is spending the sweat of its laborers, the genius of its
scientists, the hopes of its children.”
“The cost of one modern heavy bomber is this: a modern
brick school in more than 30 cities. It is two electric power
plants, each serving a town of 60,000 population. It is two
fine, fully equipped hospitals. It is some fifty miles of
concrete pavement.”
“We pay for a single fighter plane with a half million bushels
of wheat. We pay for a single destroyer with new homes
that could have housed more than 8,000 people.”
-Dwight Eisenhower
Speaking against the military build up of the cold war 22

Price vs. Cost What’s the price? vs. How much does that cost?
Price= Amount buyer (or consumer) pays
Cost= Amount seller pays to produce a good
Investment Investment= the money spent by BUSINESSES
to improve their production
Ex: $1 Million new factory
25 •Consumer Goods- created for direct consumption
(example: pizza)
•Capital Goods- created for indirect consumption
(oven, blenders, knives, etc.)
•Goods used to make consumer goods

The Four Factors of Production ALL resources can be classified as one of the
following four factors of production:
26
1. Land -All natural resources that are used to produce
goods and services. (Ex: water, sun, plants, animals)
2. Labor -Any effort a person devotes to a task for
which that person is paid. (Ex: manual laborers,
lawyers, doctors, teachers, waiters, etc.)
3. Capital - Physical Capital- Any human-made resource that is used
to create other goods and services ( Ex: tools, tractors, machinery, buildings, factories, etc.)
Human Capital- Any skills or knowledge gained by a worker through education and experience

4. Entrepreneurship -ambitious leaders that
combine the other factors of production to create goods
and services.
• Examples-Henry Ford, Bill Gates, Inventors, Store
Owners, etc.
The Four Factors of Production
Entrepreneurs:
1. Take The Initiative
2. Innovate
3. Act as the Risk Bearers
So they can obtain _________.
Profit = Revenue - Costs
PROFIT

What is the Production Possibilities Curve?
• A production possibilities curve (or frontier) is a model that shows alternative ways that an economy can use its scarce resources
• This model graphically demonstrates scarcity, trade-offs, opportunity costs, and efficiency.
4 Key Assumptions
• Only two goods can be produced
• Full employment of resources
• Fixed Resources (Ceteris Paribus)
• Fixed Technology 30

least costly way.
• This is any point ON the Production
Possibilities Curve
Allocative Efficiency-
• The products being produced are the
ones most desired by society.
• This optimal point on the PPC depends
on the desires of society.

Why do people trade?
1. Assume people didn’t trade. What things would
you have to go without?
Everything you don’t produce yourself!
(Clothes, car, cell phone, bananas, health care, etc)
The Point: Everyone specializes in the production
of goods and services and trades it to others
2. What would life be like if cities couldn’t trade
with cities or states couldn’t trade with states?
Limiting trade would reduce people’s choices and
make people worse off.
The Point: More access to trade means more
choices and a higher standard of living. 59

Absolute Advantage
One nation can produce more output
with the same resources as the other
61
Comparative Advantage
One nation can produce a good at a lower
opportunity cost than the other
![Page 62: UNIT 1: Basic Economic Concepts - Phillipa's home …phsecon.weebly.com/uploads/2/1/9/3/21939842/micro_unit_1...Unit 1: Basic Economic Concepts Length: 2.5 Weeks Chapters: 1 and 2](https://reader034.fdocuments.in/reader034/viewer/2022051722/5aa5fd267f8b9a7c1a8e2530/html5/thumbnails/62.jpg)
Per Unit Opportunity Cost Review
Assume it costs you $50 to produce 5 t-shirts. What is
your PER UNIT cost for each shirt?
$10 per shirt
Now, take money our of the equation. Instead of
producing 5 shirts you could have made 10 hats.
1. What is your PER UNIT OPPORTUNITY COST for
each shirt in terms of hats given up?
1 shirt costs 2 hats
2. What is your PER UNIT OPPORTUNITY COST for
each hat in terms of shirts given up?
1 hat costs a half of a shirt 62

Per Unit Opportunity Cost Review Ronald McDonald can produce 20 pizzas or 200 burgers
Papa John can produce 100 pizzas or 200 burgers
1. What is Ronald’s opportunity cost for one pizza in
terms of burgers given up?
2. What is Ronald’s opportunity cost for one burger in
terms of pizza given up?
3. What is Papa John’s opportunity cost for one pizza in
terms of burgers given up?
4. What is Papa John’s opportunity cost for one burger
in terms of pizza given up?
63
Ronald has a COMPARATIVE ADVANTGE in the
production of burgers
Papa John has a COMPARATIVE ADVANTAGE in the
production of pizza
1 pizza cost 10 burgers
1 burger costs 1/10 pizza
1 pizza costs 2 burgers
1 burger costs 1/2 pizza

Absolute and Comparative Advantage Absolute Advantage
•The producer that can produce the most output OR
requires the least amount of inputs (resources)
•Ex: Papa John has an absolute advantage in pizzas
because he can produce 100 and Ronald can only
make 20.
Comparative Advantage
•The producer with the lowest opportunity cost.
•Ex: Ronald has a comparative advantage in burgers
because he has a lowest PER UNIT opportunity cost.
64
Countries should trade if they have a relatively lower opportunity cost.
They should specialize in the good that is “cheaper” for them to produce.

Scarcity Means There Is Not Enough For
Everyone
Government must step in to help allocate
(distribute) resources 76

Scarcity Bus Ride Scenario:
A group of 40 college students get on a bus to go
to a dance 30 miles away.
Shortly after leaving, the bus finds that it is too
heavy to go over a large hill
10 students need to get off the bus
You and your partner need to find 5 different
ways to decide who should get off the bus.
1. Are any of the solutions fair?
2. How are resources allocated in communism?
3. How are resources allocated in capitalism?
4. What role do prices play in capitalism? 77

Every society must answer three questions:
The Three Economic Questions 1. What goods and services should be
produced?
2. How should these goods and services be produced?
3. Who consumes these goods and services?
The way these questions are answered
determines the economic system
An economic system is the method used by a
society to produce and distribute goods and
services. 78

Centrally Planned Economies
In a centrally planned economy (communism)
the government…
1. owns all the resources.
2. answers the three economic questions
Examples: Cuba, North Korea, former Soviet Union, and China?
Why do centrally planned economies face problems of poor-quality goods, shortages,
and unhappy citizens? Little incentive to work harder and central
planners have a hard time predicting preferences 81

Irrational Soviet Production Soviet companies were not guided by prices or profit. Gov’t officials
determined output quotas based on quantitative measurements. Businesses were paid based on meeting these quotas.
1. Why did a business make desk lamps that were filled with lead that were almost too heavy to carry?
2. Why did light bulb producers only make tiny night light size bulbs?
3. Why did oil companies drill many shallow holes when they knew that oil deposits are usually found in deep holes that require
slower drilling? 4. Why did a construction superintendent order his workers to
remove bathtubs from the first floor and install them in the third floor while he slowly lead inspectors through apartment building.
5. Why did black market vendors sell burned out light bulbs?
82
Production quota based on weight
Production quota based number of bulbs produced
Production quota based number of feet drilled
Quota on # of apartments complete at inspection
Business got resources before the public so workers would steal good light bulbs from work and replace them with burnt out bulbs

Advantages and Disadvantages
1. Low unemployment-everyone has a job
2. Great Job Security-the government doesn’t go out of business
3. Equal incomes means no extremely poor people
4. Free Health Care
What is GOOD about
Communism? What is BAD about
Communism? 1. No incentive to work
harder 2. No incentive to
innovate or come up with good ideas
3. No Competition keeps quality of goods poor.
4. Corrupt leaders 5. Few individual
freedoms 83

Characteristics of Free Market
1. Little government involvement in the economy.
(Laissez Faire = Let it be)
2. Individuals OWN resources and answer the
three economic questions.
3. The opportunity to make PROFIT gives people
INCENTIVE to produce quality items
efficiently.
4. Wide variety of goods available to consumers.
5. Competition and Self-Interest work together to
regulate the economy (keep prices down and
quality up). Reword for Communism 86
![Page 87: UNIT 1: Basic Economic Concepts - Phillipa's home …phsecon.weebly.com/uploads/2/1/9/3/21939842/micro_unit_1...Unit 1: Basic Economic Concepts Length: 2.5 Weeks Chapters: 1 and 2](https://reader034.fdocuments.in/reader034/viewer/2022051722/5aa5fd267f8b9a7c1a8e2530/html5/thumbnails/87.jpg)
Example of Free Market Example of how the free market regulates itself:
If consumers want smartphones and only one
company is making them…
•Other businesses have the INCENTIVE to start
making smartphones to earn PROFIT.
•This leads to more COMPETITION….
•Which means lower prices, better quality, and
more product variety.
•We produce the goods and services that society
wants because “resources follow profits”.
The End Result: Most efficient production of the
goods that consumers want, produced at the lowest
prices and the highest quality. 87
![Page 88: UNIT 1: Basic Economic Concepts - Phillipa's home …phsecon.weebly.com/uploads/2/1/9/3/21939842/micro_unit_1...Unit 1: Basic Economic Concepts Length: 2.5 Weeks Chapters: 1 and 2](https://reader034.fdocuments.in/reader034/viewer/2022051722/5aa5fd267f8b9a7c1a8e2530/html5/thumbnails/88.jpg)
Example of Central Planners Example of why communism failed:
If consumers want smartphones and only one
company is making them…
•Other businesses CANNOT start making
computers.
•There is NO COMPETITION….
•Which means higher prices, lower quality, and
less product variety.
•More phones will not be made until the
government decides to create a new factory.
The End Result: There is a shortage of goods that
consumers want, produced at the highest prices
and the lowest quality. 88
![Page 89: UNIT 1: Basic Economic Concepts - Phillipa's home …phsecon.weebly.com/uploads/2/1/9/3/21939842/micro_unit_1...Unit 1: Basic Economic Concepts Length: 2.5 Weeks Chapters: 1 and 2](https://reader034.fdocuments.in/reader034/viewer/2022051722/5aa5fd267f8b9a7c1a8e2530/html5/thumbnails/89.jpg)
The Invisible Hand The concept that society’s goals will be met as
individuals seek their own self-interest.
Example: Society wants fuel efficient cars…
•Profit seeking producers will make more.
•Competition between firms results in low
prices, high quality, and greater efficiency.
•The government doesn’t need to get involved
since the needs of society are automatically
met.
Competition and self-interest act as an invisible
hand that regulates the free market. 89

1. Companies are greedy and do anything to screw over consumers!
• Companies have an incentive to satisfy the needs of consumers. If they don’t they will go out of business.
2. Capitalism causes companies to outsource US jobs overseas. America suffers because companies want more profit!
• How many of you lost your job to outsourcing? • How many of you benefit in the form of lower prices? 3. Capitalism only helps the rich. US companies enslave and
exploit third-world workers in sweatshops! • Sweatshop workers are not forced labor. They make the
decision to work there voluntarily. Why? • Although the working conditions are far below US
standards, working in a sweatshop is better that the alternative • Sweatshop wages in Vietnam, Honduras, and Nicaragua
are more than double the country’s average wage.

Sweatshops Then
Sweatshops Now
Question: Who is to blame for
these people being so poor?
Answer: Low productivity.
If a country doesn’t produce very
much, it can’t afford to pay it’s
workers very much.
Why do these countries have
such low productivity?
Corrupt governments,
inadequate physical capital and
infrastructure, and
underdeveloped human capital.
What does foreign investment
bring to poor countries?
"My concern is not that there are too many sweatshops, but
that there are too few." -Jeffrey Sachs, Harvard University
