How to think like anEconomist!

You Can’t Always Get What You Want…

“And you can’t always get what you want,

Honey, you can’t always get what you want

You can’t always get what you want

But if you try sometime, yeah,

You just might find you get what you need!”

-Mick Jagger and Keith Richards1969

Essential QuestionWhy can’t you always get what you want?

Simply stated, this chorus explains why everyone has to make choices…

We will explore this question in Unit I…

What is Economics?

• The study of how people allocate their limited resources to satisfy their unlimited wants.

• The study of how people make “choices”.

Why is it a Social Science?

• It deals with the behavior of people as they cope with the fundamental problem of scarcity.

What does Economics deal with?

• Describing economic activity

• Analyzing economic activity

• Explaining economic activity

• Predicting economic activity

What do you think each ofthese questions means?

Why is what we want scarce?

• Scarcity: the fundamental economic problem facing all societies.

Why does this condition arise?

• Wants > Resources

• Goods and services are scarce because the resources needed to produce them are scarce!

Everything is Scarce!

WHY DOES THE CONDITION ARISE?

ActivityScarcity Pictograms

• Pictogram: a symbolic representation of a word that shows its meaning

• Create a pictogram to illustrate your interpretation / definition of each of the following terms:

- Wants - Goods

- Needs - Scarcity

W A N T S

RECAP – “Scarcity”

• Scarcity occurs when the limitedingredients (resources) for producing things that people want are insufficient to satisfy all wants.

• Take the production of “cookies”.

– The ingredients needed to produce cookies are “limited”.

» sugar, flour, M&Ms, the baker (that’s me)

Why is what we want scarce?

Look around the classroom…

1. List 3 goods that you see in the classroom and 2 services that exist in this school.

2. Explain why these goods/services are scarce.

How did the goods/services

get here?

Nothing appears

magically…

These goods/services

were produced to satisfy our wants…

Essential Question:

How do we satisfy our economic

wants?

Factors of Production

• Provide the means for a society to produce and distribute goods and services.

Exit Ticket

• How has scarcity affected your life?

• What did you do in result of it?

Warm-up: Factors of Production

Which factor of production is each of the following?

Three Basic Economic Questions

3 Q’s are answered in order to make decisions about the ways

limited sources will be used.

1. What to produce?

2. How to produce?

3. For whom to produce?

Answering the 3 basic economic questions in a Market Economy [i.e., U.S.]

What to produce?What should we devote our resources to?

How to produce?What methods should be used in production?

What is most efficient?

For whom to produce?Who can afford the product?

Trade-offs

Trade-offs exist because we cannot have everything we want.

Choices must be made to satisfy our wants and needs.

Examples…

Some choices are easy to make…

Hmm…Should I have pizza or a hoagie for lunch today?

Other decisions are agonizing…

Should I get out of bed and go to school today or should I sleep in?

Personal Trade-offs…

If you were given $50.00, what would you do with it?

Each choice in a trade-off has advantages and disadvantages…

Reflecting on Personal Trade-offs…

Write down three [3] examples of trade-offs you made in the last week…

Be prepared to share!

Opportunity Cost

When comparing the top 2 choices, it is the BENEFIT of the next best alternative that must be sacrificed to satisfy a want.

Not all possible things given up.

The best thing we give up to get what we want.

Why it Matters

Understanding the opportunity costs of different choices in life makes you a

better decision-maker!

You always have to give something up…

ECONOMICS IS EVERYWHERE!

Warm-Up

1. Take out your photograph2. Switch photographs with the person next to you.3. Identify examples of goods and services in the

photograph. Time: 3 min4. Based on the list you created in question 2, classify each

good/service as an example of the factors of production. [land, labor, capital] Time: 3 min

5. According to the photograph, how might scarcity affect daily life? What are some of the opportunity costs of your daily

decisions?

Reviewing key concepts from yesterday…

What is the opportunity cost that arises from each of the following trade-offs?

I packed my lunch all week so I had money to go out to dinner on Friday.

I went to work on Thursday night to earn money rather than studying for a test I had on Friday.

I did not go to the movies with my friends so I would have money to buy gas.

I turned down an offer to Princeton [on full scholarship] so I could go to Penn State University

…located in the happiest valley in the world!

HOW CAN WE MEASURE WHAT WE ARE GAINING AND LOSING

WHEN MAKING CHOICES?

Essential Question

Measuring Opportunity Cost Graphically…Production Possibility Frontiers

Production Possibility Frontier [PPF]:

Represents all possible combinations of total output that could be produced when all resources are fully employed and used efficiently.

Why is the PPF curve downward sloping?

Trade-offs

We are always making a choice and giving something up

By “resources”, we mean the 4 Factors of Production

Imagine that you have $5 and there are 2 things you really want to buy: chocolate and ice cream…

Example…

Prices:

1. How many chocolate bars can you buy instead of one ice cream cone?

2. How many ice cream cones can you buy instead of one chocolate bar?

Example…

Chocolate Bar $0.50

Ice Cream Cone $1.00

What you give up------------------What you get

BOWED-OUT PPFs Varying O.C.

Principle of Increasing Costs: As a society produces more of one product, the O.C. of producing that product increases because we are using more resources that

are poorly suited to produce it.

2. Put corn on the x-axis.

3. Put beads on the y-axis.

4. Label all points!

Productivity

What makes productivity increase?

Productivity increases when more output can

be produced with the same amount of inputs.

Efficiently using all four factors of

production will lead to greater productivity…

Three Ways to Increase Productivity

1. Specialization

Productive inputs specialize in the task they do best

2. Division of Labor

Workers perform fewer tasks more frequently

PRACTICE MAKES PERFECT!

Three Ways to Increase Productivity

3. Investment in Human Capital

Sum of all skills, abilities, health, and motivation of people

Examples – training, healthcare, motivational programs

“It is what you would be left with if someone stripped away all of your

assets and left you on a street corner with only the clothes on your back”

Problem Set # 1

A society can make either guns or butter

Put guns on the x-axis and butter on the y-axis

Label the following points:

Point Guns Butter

A 5 3

B 3 9

C 1 15

Problem Set # 2

A society can make either Jeeps (x-axis) or Cars (y-axis)

If the economy makes 100 cars, it can‟t make any jeeps

If the economy makes 200 jeeps, it can‟t make any cars

Problem Set #3 - Exploring the Essential Question

Imagine that a new society, Paternoville, produces only two items: Footballs and Peachy Paterno Ice Cream.

Use the information on the table below to construct a Production Possibilities Frontier with Footballs on the x-axis and Peachy Paterno Ice Cream on the y-axis.

Who do you think owns the businesses shown in this picture?

How is the local economy affected when competitors open up near

these local businesses?

Exploring “Isms”: Capitalism

What is capitalism?

A system in which private citizens own the factors of production

What is competition?

A struggle among sellers to attract consumers while lowering costs

Capitalism thrives on

competition

Sellers compete for the most

buyers

Buyers compete to find the best products at the

lowest price

Competition is allowed to flourish with a minimum of government interference

* The U.S. is ‘mixed’ because some government regulation / interference does exist

Another term to describe the American Economic system

What is a „free enterprise‟ economy?

Entrepreneur

• Organizes and manages land, labor, and capital in order to seek profits

• Both the “spark plug” and the catalyst of the free enterprise economy

• When successfully, everyone benefits...how?

Consumer

• Determine what products are ultimately produced

• Their decisions often are the power of the economy…why?

Government

• Protector• Enforces laws that

protect consumers, workers, and businesses

• Provider/Consumer• Provides defense

services, education, and public welfare

• Consumes goods and services at all levels

• Regulator

• Promoter of National Goals• Reflects the will of a

majority of its citizens
