2. The 7 Principles of Economic Thinking

3. The 7 Principles of Economic Thinking
Scarcity Forces Trade-offs
Cost vs. Benefits
Thinking At the Margin
People Respond to Incentives
Trade Makes People Better Off
Markets Coordinate to Trade
Future Consequences Count

4. Scarcity Forces Tradeoffs
PRINCIPLE #1
Scarcity Forces Tradeoffs
The inability to satisfy all wants at the same time;
the NEEDS are greater than the RESOURCES
SCARCITY
People have
Unlimited Wants…
… but Resources
are Limited
Food
Clothing
Shelter
Schools
Hospitals
Cars
Transportation
Land
Soil
Minerals
Fuels
People
Money
Technology

5. Scarcity Forces Tradeoffs
SCARCITY forces us to choose which needs and wants to satisfy with available resources.
There is no such thing as a “free lunch.”

6. Scarcity Forces Tradeoffs
In other words, a TRADEOFF is your choice
to play a sport, knowing you are giving up free time.
Time is a limited resource (even if you are a billionaire, you still only have 24 hours in a day!)
By choosing to spend 4 hours at practice,
you are giving up the 4 hours you would have spent sleeping, watching TV, or studying (yeah, right!)
if you didn’t play sports.

7. ROAD TRIP!
You and a friend have decided to take a road trip to follow your favorite band on tour.
Will you buy a large, comfy sedan with low gas mileage OR
Will you buy a small car with great gas mileage?
What are the tradeoffs associated with your choice?
Trade roominess for good gas mileage OR
Trade good gas mileage for nicer car

8. PRINCIPLE #2
Costs vs. Benefits
Economists assume that choices are made based on expected costs and benefits

9. COST-BENEFITS ANALYSIS
Costs vs. Benefits
Every choice has a COST.
Think About It…
When you chose to come to school,
what was your cost?
And if you had chosen to stay
home and sleep…?
When people weigh the costs
(money, time, effort, energy, some
other sacrifice) against the perceived
gain (money, time, experience, other improvement),
this is known as a
COST-BENEFITS ANALYSIS

11. COST-BENEFITS ANALYSIS ?
Costs vs. Benefits
What’s Jerry’s
COST-BENEFITS ANALYSIS ?

12. ROAD TRIP! Cost of hotel room is more than campground
Each evening you have to make a choice –
Pitch a tent at an inexpensive campground OR
Pay more for a motel room with a soft bed, a shower, and no mosquitos
Cost of hotel room is more than campground
Are the Benefits of the hotel room worth the extra cost?

13. PRINCIPLE #3 Thinking at the Margin
“Thinking at the Margin” = What is the benefit of adding ONE more?
T-shirts on sale for $10 each – at a certain point adding ONE more t-shirt is not worth it anymore.
$7.99 w/ads, or Hulu $9.99 w/OUT ads?

14. Thinking at the Margin
1:15

15. ROAD TRIP! Your road trip was planned for a six city tour.
But then the band announces ONE MORE concert!
This added concert is NOT in your plans, but you would really hate to miss it!
This is a decision you must make at the MARGIN.
Is the marginal benefit of attending the seventh concert worth the added costs in time & money?

16. People Respond to Incentives
PRINCIPLE #4
People Respond to Incentives
Incentives – anything used to change peoples’ behavior.
POSITIVE
INCENTIVES
NEGATIVE
INCENTIVES
Motivate behavior
Examples?
Discourage behavior
Examples?

17. People Respond to Incentives
Incentives Video:

18. ROAD TRIP!
One morning on your road trip you were pulled over by police for going 65 miles in a 50-mile-per-hour zone.
Uh-oh! It was also a construction zone, so your fine will be doubled.
Your decision to ignore the speed limit signs will cost you a $300 fine.
You decide the $300 fine is enough incentive for you to watch your speed from now on.

19. Trade Makes People Better Off
PRINCIPLE #5
Trade Makes People Better Off
Trade is VOLUNTARY.
Only trade if believe it is in best interest.
Chik-fil-A wants your money, you want their food – trade helps you both.

20. Trade Makes People Better Off

21. ROAD TRIP! One morning, you turn the key in your car…nothing happens.
Neither you nor your friend is a mechanic, so you push the car to the nearest gas station and look for help
The mechanic on duty figures out you have a dead battery.
You offer to trade your two tickets for that night’s concert for a new battery.
You are disappointed about missing the concert, but everyone agrees that trading the battery for the tickets makes you all better off than you were that morning.

22. Markets Coordinate to Trade
PRINCIPLE #6
Markets Coordinate to Trade
Parties that trade want to make it as simple as possible.
Examples:
Many stores in one location at a mall
Many brands of food sold in the same grocery store.
Amazon, Ebay, let you get ANYTHING in one place 2AM in your PJ’s…)

23. Markets Coordinate to Trade

24. MARKETS COORDINATE TRADE WITH REMARKABLE EFFICIENCY
ROAD TRIP!
On your road trip, you visit a grocery store.
As you push your cart through the aisles, you see fresh mangos from Mexico, bananas from Belize, shrimp from Thailand, cheese from France, and salmon from Alaska.
You wonder how a grocery store manages to stock its shelves wit so many fresh foods from around the world at prices you are willing to pay.
It’s because…
MARKETS COORDINATE TRADE WITH REMARKABLE EFFICIENCY

25. Future Consequences Count
PRINCIPLE #7
Future Consequences Count
Economists always think about the future
“If we raise taxes, what will be the effect?”
“Law of Unintended Consequences” – if we don’t think through all possibilities, we may be surprised by the result.

26. Future Consequences Count
PRINCIPLE #7
Future Consequences Count
Future Consequences Count video:

27. ROAD TRIP!
Your road trip had a variety of consequences – some intended, others not.
Short term – find out what it’s like to be on our own, away from family; learn how to deal with difficult situations
Unintended consequences – your insurance bill months later shows that your insurance costs have gone up because you chose to ignore a speed limit sign!
