Tuesday April 3rd
Warm Up: What is Economics? How do you feel about
Economics?
![Page 2: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/2.jpg)
Learning Objectives
SWBAT:
•Identify and explain some basic economic principles
•Apply basic economic principles to the elementary classroom
•Evaluate if teaching students to think like economists will help them make better decisions in their future.

Average Citizen on Economics
• Economics is about making money!
• Money is not the focus of economics.
![Page 5: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/5.jpg)
Students on College Economics
• The dismal science
– It’s difficult
– It’s boring
– It’s not relevant to me
![Page 6: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/6.jpg)
Let’s Get Relevant?
• Traditional economics
– College textbooks • Principles of Economics includes:
– every economic concept of last 200 years!
– Taught by lecture, graphs, lots of chalk
![Page 7: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/7.jpg)
Consequence for K-12 Education
• K-12 teachers– often avoid college economics
courses!
• If they do take such a course, – Retain little
• Lack “economic way of thinking” • Lack enthusiasm • Lack ideas on how to teach
economics
![Page 8: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/8.jpg)
How People Learn
John Bransford
• This is a problem …
– “Content knowledge of the teacher is crucial for student learning.”
![Page 9: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/9.jpg)
Our Nation’s Dilemma
• Less than 25% of adults experience a college economics course
• Those who do, unlikely to “internalize” concepts
• Critical need– K-12 economic education for teachers
• deliver economics in schools
![Page 10: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/10.jpg)
Content: What Should It Be?
• We must
– teach students how to think
![Page 11: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/11.jpg)
• The theory of economics does not furnish a body of settled conclusions …
– it is a method rather than a doctrine,
– an apparatus of the mind, which helps its possessor to draw correct conclusions.John Maynard Keynes
1883-1946
![Page 12: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/12.jpg)
Economics Is …
. . . not a body of knowledge,
– but it is a way of thinking
![Page 13: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/13.jpg)
Methodology: How to Teach?
• How do you teach a skill?– Baseball, piano, economics
• Practice!– “Activity-based” learning
• not strict lecture• not memory
• What’s Worth Teaching? Mark Brady– Students retain:
• 20% of what they see and hear• 80% of what they experience
![Page 14: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/14.jpg)
Objectives
• Content– Strengthen background
• A sampler
• Pedagogy:– Experience activities
• Enthusiasm
![Page 15: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/15.jpg)
Would you like a Butterfinger?
• ______ Wants
• 1 Butterfinger
• What is the economic problem?
![Page 16: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/16.jpg)
Scarcity
• Inability to satisfy everyone’s wants
– Multiple uses for each resource
• must choose how/where to use
![Page 17: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/17.jpg)
What Is Scarce?
• Productive Resources:
• natural resources (land)
• human resources (labor)
–entrepreneurship
• man-made resources (capital)
technology
![Page 18: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/18.jpg)
Scarcity Choice
• Economics is:
– the study of choice
![Page 19: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/19.jpg)
Key Concept
• Individuals and societies face tradeoffs
• and must make choices.
![Page 20: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/20.jpg)
Scarcity Choice
![Page 21: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/21.jpg)
In Groups
• Discuss how elementary students experience scarcity.
• How does scarcity in their lives require them to make choices?
![Page 22: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/22.jpg)
The Economic Way of Thinking
• Economists study:
(1) why people choose what they do
(2) consequences of people’s choices– for the individual– for society
(3) if inefficient, how improve the outcome?
![Page 23: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/23.jpg)
Candy Bar Activity
• One Volunteer, please?
• Opportunity lost opportunity cost
– Value of the best foregone alternative
– “Choosing is refusing”
– choose A, refuse B –
» cost of A is value of B
![Page 24: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/24.jpg)
The Dismal Science!
There’s no such thing as a free lunch!
![Page 25: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/25.jpg)
Key Concept
• Choice involves cost
» opportunity cost
![Page 26: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/26.jpg)
Why Do People Save?
• To provide for future needs
• This is the BENEFIT of saving
![Page 27: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/27.jpg)
Every Choice Has a Cost!
• Opportunity cost of saving?
– What you give up to get something
– If save, cannot spend now
• give up present consumption
![Page 28: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/28.jpg)
Economics: a Study of Choice
• In choosing, we weigh:
–BENEFIT of future consumption
versus –COST of less consumption now
B(X) C(X)
![Page 29: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/29.jpg)
Why Do Americans Save So Little?
• C(X): sacrifice immediate gratification
• B(X):– Expected future consumption
• or bequest to children
• For many, the C(X) > B(X) . . . • and the data . . .
![Page 30: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/30.jpg)

Impatience: Instant Gratification
Choose among 24 movie videos
• some “low brow” – My Cousin Vinny
• some “high brow” – Schindler’s List
• Picking for tonight:
– 56% of subjects choose low brow.
• Picking for next Thursday:
– 37% choose low brow.
• Picking for second Thursday:

Consequence of Faulty Discounting
• Average adult –
– $6,000 outstanding credit card debt.
• Few can afford to pay in full,
– so make minimum payment each month
– pay interest at very high rates on balance.
• Immediate gratification is a powerful force!
![Page 38: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/38.jpg)
Since Scarcity Implies Choice
• … and since choice involves cost
Why choose it?
• Assume that:
– People choose X if:
• B(X) > C(X);
–otherwise, not
» where B(X) = benefit of choice X
![Page 39: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/39.jpg)
Play It Again, Sam
• Raise the cost
– if C(X) > B(X), • choose another bar
![Page 40: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/40.jpg)
In Your Group
• Discuss how elementary students make choices based on the costs and benefits.
• Could weighing the costs and benefits of choices help students make better decisions?
• What type of decisions?
![Page 41: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/41.jpg)
Key Concept
• People respond to incentives
![Page 42: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/42.jpg)
Consequences
• People respond to incentives causing
–intended consequences, and
–unintended consequences• can offset the intended benefits
![Page 43: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/43.jpg)
People Respond to Incentives
• Mandated auto protection– seat belts
– air bags
– antilock brakes
• Intended consequence?– “Seat belts save lives!”
![Page 44: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/44.jpg)
Driving Speed
• Benefits of driving fast, B(X)?– Get there faster– Thrill
• Costs of driving fast, C(X)?– Ticket, fine– Accident, injury– Insurance premium
![Page 45: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/45.jpg)
Driving and Snow
• What happens when it snows?– On average, people slow
down.
– Why?• C(X) goes up • for many, C(X) now
exceeds B(X), –people respond to
incentives
![Page 46: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/46.jpg)
Driving & Seat Belts
• What happens when people wear seat belts?– C(X) goes down
• B(X) > C(X) for some• who now drive faster• more accidents
• Unintended consequence?– Seat belts increase
injury!
• Net Benefit?
![Page 47: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/47.jpg)
Consequences
• People respond to incentives

The Camel Race
• Two Bedouins met in the desert, and fell into an argument over their camels, each claiming that his was the slowest, “stubbornest,” most useless camel in all of Arabia. The argument ended in a bet. They agreed to race to the oasis, two miles away, whichever camel arrived last would be proved slowest, and his owner would win ten dirham from the other.
![Page 49: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/49.jpg)
Camel Race continued
• . . . They got on their camels, and set off slowly toward the oasis. More slowly, still more slowly. After a while, it became clear that since each Bedouin was trying to win the bet, they were never going to make it to the oasis.
• . . . After a while, a wise sheik rode up on a donkey and asked them why they and their camels were standing still, in the middle of the desert, on a hot day, with the oasis less than two miles away.
![Page 50: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/50.jpg)
The Camel Racecontinued
• They got off their camels, and all three sat down in the shade of a rock while the two Bedouins explained about their bet. The wise sheik whispered two words to them. The Bedouins immediately jumped on the camels and rode off as fast as they could towards the oasis.– What were the two
words? ________ _________
• Switch camels!

In your groups
• Discuss how students respond to incentives in the classroom.
• What incentives work, what don’t….why?
![Page 53: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/53.jpg)
Concepts Review
Students understand that because of the condition of scarcity, decisions must be made about the use of scarce resources.
– 1.1: scarcity choice cost
– 1.2: people respond to incentives
– 1.3: broadly applied to all people
![Page 54: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/54.jpg)
Economic Systems
• Every country must make these choices:
– What to produce?
– How to produce?
– For whom to produce?

Goals of an Economic System?
• Economic Growth (standard of living)• GDP level & growth rate• Standard of living: health, literacy, life expectancy, etc.
• Economic Equity -- some measure of fairness
• Economic Stability/Security• inflation & unemployment• safety net: social security, welfare
• Economic Freedom -- freedom to buy, work
• Economic Efficiency -- minimize waste

Discuss in your groups….• What do elementary students know about
these economic goals?
• What experiences have they probably had with them?
• Economic Growth
• Economic Equity
• Economic Stability
• Economic Freedom
• Economic Efficiency

From Marx to Markets
• Why are so many countries in transition from command socialism to market capitalism?
– Capitalist market economies tend to have:
• higher economic freedom
• higher economic growth & standard of living
![Page 68: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/68.jpg)
The 75-year Experiment
• . . . collapses in the early 1990s
• Soviet Union breaks up into 15 independent states, and
• Eastern & central European nations become independent of former Soviet bloc
• The 75-year experiment of the Soviet version of command socialism ends

Consequence of Socialism• From each according to his
ability to each according to his need.– Intended Consequence?
• equity
– Unintended Consequence?• transfer income from rich to poor,
– those generating income (water), can’t keep it, so work less
– Those receiving income, receive without work, so work less
• More equity, implies less efficiency– Less total income: “leaky bucket”

What Markets Do Best?
Transmit information to decision-makers
![Page 78: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/78.jpg)
The central task of economic systems:
rapid adaptation to changes in the particular circumstances of time & place
Transmitting Information
Friedrich von Hayek
![Page 79: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/79.jpg)
Examples of Market transmitting information
• Hurricane in Florida kills crops of oranges...what happens to the price of oranges?
• Wii console drops in price….what is the market telling us?
![Page 80: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/80.jpg)
In your groups
• Discuss what experiences your students have with the market of supply and demand?
• Can they understand it? Why or why not?
![Page 81: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/81.jpg)
Since economics is the study of
choice…

![Page 82: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/82.jpg)
The Fish Activity
• Four volunteers
• Rules:– 0 to 15 seconds
• 1 point per Fish
– 15 to 30 seconds• 2 points per Fish
– Person with most gets 1 point bonus
– Game ends when all fish taken.
![Page 83: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/83.jpg)
About the Fish Activity . . .
• Were you surprised with the general outcome?
• Why or why not?
• What did you assume about your colleagues?
![Page 84: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/84.jpg)
The Economic Perspective
• Economics is the study of choice,– assuming that people are:
• rational, and
• self-interested
• This is the predictable element in human behavior,– the fundamental assumption of economics
• economic man
![Page 85: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/85.jpg)
The Fish Activity
• Step 1: Understand choice of people
– B(X) -- your gain if you wait?• 0 points
– C(X) -- cost of waiting • 1 point (per fish you might have
“caught”)
– Net Benefit
• minus 1 point
• Understand or predict by assuming:– self-interested people weigh B(X) vs
C(X)
![Page 86: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/86.jpg)
Market Failure
• Size of the “pie” is smaller than potential
• Society is wasting scarce resources!
• Identify the failure.
![Page 87: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/87.jpg)
The Fish Activity
• What generated the problem in this activity?
• Why did the group fail to achieve the efficient outcome?
![Page 88: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/88.jpg)
If the Problem is Greed . . .
• Possible to eliminate greed?
• Want to eliminate greed?
• Consider:– Can we capitalize
on greed by steering for benefit of others?
![Page 89: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/89.jpg)
Self-Interest or Greed Assumption
• What’s the problem? Why did your airplane not take off?
• Gravity! The problem is gravity.
• What does this have to do with economics?
The Aeronautical Engineer Story . . .
![Page 90: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/90.jpg)
The Blame . . . • Health care:
– “the problem with health care in the U.S. is– greedy insurance companies– greedy hospitals– greedy doctors– greed, greed, greed, that’s what’s to blame!”
• Public Education– “the problem with education in the U.S. is
– lousy administrators– lazy teachers– children who don’t care– and many other ills caused by self-interested people.”
![Page 91: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/91.jpg)
Where to Place the Blame?• Economists assume self interest
– Just as the aero engineer must assume gravity
– We are not ready to suspect any person of being defective in selfishness.
» Adam Smith, 1776
• Economists do NOT blame the people!• Instead, consistently poor outcomes
– result from poor incentives– generated by the underlying structural problem
![Page 92: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/92.jpg)
The Fish Activity Again
• Four volunteers• Rules:
– 0 to 15 seconds• 1 point per fish
– 15 to 30 seconds• 2 points per fish
– Person with most gets 1 point bonus.
– Game ends when all markers gone
– But, define property for each participant.
![Page 93: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/93.jpg)
Steps 1 and 2 for the Pencil Activity
• Step 1: Understand• define X = wait.
– B(X): 1 point• since benefit accrues to you
– C(X): 0.00• since don’t lose your
property
– NB(X): + 1 point• thus, tend to wait.
– Efficiency!• Size of pie is maximized
– Participants:• Acting out of self-interest?
![Page 94: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/94.jpg)
The Cause of Failure• What is the source of the fish failure?
– Lack of well-defined and enforced
private property rights
– To function properly, markets require property rights
• self-interest steered for the benefit of society
• Note: do not say the failure is “self interest”• do not blame the fishermen• do not blame the loggers
![Page 95: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/95.jpg)
The Three-step Process
• Step 3: –Consider Policy
Alternatives
• A potential role for government
![Page 96: Tuesday April 3rd](https://reader035.fdocuments.us/reader035/viewer/2022062308/56813035550346895d95cdbe/html5/thumbnails/96.jpg)
Step 3: Government Policy• Policy Option #1:
– Create property rights that are:• well-defined• well enforced, & • marketable.
But this is the essence of Capitalism!

Germans tell a story . . . • ... two women were carrying a laundry basket filled
with money to the bank. • The women saw a crowd gathered around a shop
window and put down their basket to peer into the window to see if there was anything they might purchase.
• When they turned around a moment later, their money
was in a pile, but the basket was gone.
