ECONOMICS Review from lesson ECONOMICS Review from lesson

#1…..#1…..Hot Question #1Hot Question #1: What is scarcity?: What is scarcity?

Scarcity exists. We have endless desires but limited resources.

In Economics, we must choose.

H.O.T. Question # 2: Define “Trade-off” in your own words and give an example.

• A trade-off occurs when we choose one course of action over another or one benefit over another . (K.I.M. Vocabulary Definition #1)

• In Economics, we can never have everything we want or need.

• We must make choices.• A woman spends ten dollars buying her lunch at

a local restaurant. She cannot use the same ten dollars to buy a book. A trade-off has occurred.

Again….It’s All About Scarcity!

• Scarcity exists. Our wants and desires are limitless but our natural resources are limited.

• We can always want more than we have. As such, we are constantly choosing one course of action over another.

• We cannot spend ten dollars on a movie ticket and the same ten dollars on a restaurant meal.

H.O.T. Question #3: What are the tradeoffs in the following scenarios (what benefit do you lose or give up?)

1. Dre works on his homework until 3:00 A.M. in the morning to prepare for his test at 7:00 AM at O.S.U.

2. Mr. Kirby blows his entire paycheck at Spirit Mt. Casino at the blackjack table.

3. Mr. Seymour takes out all his money from his retirement account to use as a down payment on a house.

4. A farmer wants to plant corn, broccoli and wheat on his property, but only plants wheat.

5. The government during war time decides to use all of it’s steel to produce tanks and ships.

Opportunity Cost (K.I.M. Vocabulary #2)

• Whenever we make a decision, we receive one thing but give other things up.

• If I chose to study tonight for the examination, I cannot go to the party or the movies or walk the dog.

• The most desirable alternative given up for the decision is the opportunity cost.

• Think of the opportunity cost as the best course of action of all those things you didn’t get OR

• The most prized things(s) you gave up when making a decision.

The World of Trade-Offs

• Opportunity cost graphically

– The production possibilities curve (PPC) represents all possible maximum combinations of total output that could be produced.

– Along the production possibilities curve, there is a fixed quantity of productive resources of a given quality being used efficiently.

HOT Questions:

6. What would happen to the production possibilities curve if you spent more time studying?

7. What would happen to your potential grades?

8. Is it possible that terms of the trade-off might not be constant?

Scarcity and opportunity costs affectindividuals, businesses, and governments.

HOT Question #9: What does Guns or Butter mean in economics?

Thinking at the Margin: KIM Vocabulary #3

• Sometimes a decision involves whether to add or subtract one additional unit of a resource.

• After studying many hours, a student might ask herself: “Should I study one more hour?”

• This question is a question at the margin. Deciding whether to add or subtract one additional unit occurs at the margin.

Should we study one more hour? That is thinking at the margin.

HOT Questions for Reflection:Discuss in groups: write your answers in

your notes.10. Provide examples of trade-offs.
