1. Standard
SSEF1
d. Define opportunity cost as the next best alternative

2. What makes something Scarce?
Scarcity
Must be desirable
Must be limited
Must have value (price)
In order for an item to be desirable it must have Utility (be useful).

3. Which one is really worth more?
Water Or Diamonds

4. Paradox of value Paradox of Value:
A situation where a necessity is worth less than a non-necessity
Value: refers to worth in dollars and cents OR what something is worth to you

5. Think about it….
Did you have to give up something to come to school today?

6. The NEXT BEST THING you could use your resource for.
Opportunity Cost
The NEXT BEST THING you could use your resource for.

7. Opportunity Cost
The opportunity cost of a choice is the value of what you must give up when you make a particular choice.
The choices people make have both present and future consequences.

8. Trade-Off Giving up some of one thing to get more of another
Trade-offs are all those things you could have done with your time and/or money but didn’t choose to do.

9. Try it: Opportunity cost vs. Trade off
Step 1- Think of 5 school appropriate things you would do with a couple of hours of free time this weekend . Write them down.
Step 2 – List them from #1 being your first choice to #5 being your last

11. 5 Key Economic Assumptions
Let’s Look Back….
5 Key Economic Assumptions

12. 5 Key Economic Assumptions
Society’s wants are unlimited, but ALL resources are limited (scarcity).
Due to scarcity, choices must be made. Every choice has a cost (a trade-off).
Everyone’s goal is to make choices that maximize their satisfaction. Everyone acts in their own “self-interest.”
Everyone acts rationally by comparing the marginal costs and marginal benefits of every choice (more on this later)
Real-life situations can be explained and analyzed through simplified models and graphs.

13. Activity:
Plan a Dance!

14. Plan a Dance! Group Choice Band/DJ Place Food Project 1st Choice
2nd Choice
3rd Choice
4th Choice

15. Answer the following questions in your group
What was the opportunity cost of each of your group’s decisions?
DJ?
Location?
Food?
What tradeoffs did your group make for each category?
How did individual and group preferences influence decisions?
In what ways is this problem similar to the “economizing behavior” faced by your family, and in what ways is it different?
Turn in 1 sheet of paper with all group members names on it. No name = No grade …NO EXCEPTIONS

16. Marginal Analysis In economics the term marginal = additional
“Thinking on the margin”, or MARGINAL ANALYSIS involves making decisions based on the additional benefit vs. the additional cost.

17. Marginal Cost v. Marginal Benefit
People make decisions based on costs and benefits
The benefits must equal or outweigh the costs.
Rational Decision Making takes place when marginal benefits equal or exceed marginal cost.

18. Which flight should you choose? Why?
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 the weekend
2. You work every weekday earning $100 per day
3. You have three flights to choose from:
Thursday Night Flight = $300
Friday Early Morning Flight = $345
Friday Night Flight = $380
Which flight should you choose? Why? 18

19. Cost – Benefit Analysis
Step 1 – Decide what your choices, or alternatives, are.
Step 2 – List all marginal costs (“cons”) and marginal benefits (“pros”) in a decision making grid.
Step 3 – Decide which choice (alternative) benefits you most.

20. Cost – Benefit Analysis
List 3 choices of things to do after graduation.
Use the following chart to complete a cost-benefit analysis to decide where you should go.
Choices
Cost
The “cons” or negative consequences if you choose this.
Benefits
The “pros” or positive outcomes of your decision
