1. Introduction to Economics1

2. What is Economics?
Economics is the study of how to allocate (spread/distribute) scarce resources among competing wants and needs.
OR: the study of scarcity.
What does that mean? 5

3. Less Formally...
There is not enough of everything that people want (and need) to go around.
Some people will get things and others will not. Certain products will be produced and others will not. That is a fact. The question is then, how do we determine who gets what? 6

4. How Do Economists Think - Scarcity and Goods
Scarcity is at the heart of economics. If there were no scarcity, there would be no need for economics.
Scarcity : limited amount of something desirable
arises because society does not have enough resources to produce all the things people would like to have.
These things are called goods. Goods are any items that are desired by people. 7

5. The Economic Questions
What to Produce?
How to Produce?
For Whom to Produce?

6. How Economists Think - Utility and Rationality
Economists assume that people act to maximize their own happiness
Utility- The satisfaction or happiness gained from something.
In Economics, it is not just the usefulness of something
We also assume all people act rationally: make good decisions based on self-interest. 8

7. How Economists Think - Resources
Resources- the elements that go into the production of a good or service.
AKA: factors of production or productive resources.
YOU CAN NOT CREATE A GOOD WITHOUT RESOURCES!!! 9

8. Four Resources or Factors of Production
Land - Natural Resources (raw materials)
Labor - Skills of People
Capital - Goods Used To Make Other Goods (not money)
Entrepreneurs – Risk takers who start new businesses or bring in new products in search for profits. 10

9. How Economists Think - Rationing Device
How do we decide who gets what?
A rationing device -a process by which we determine who gets what.
It could be coupons, a line, height, or alphabetical order, lottery.

13. Decisions Made at “The Margin”
An economist is always thinking dynamically. Asking themselves “what next?”
You have to think this way in this class.
Marginal analysis refers to weighing the costs and the benefits of an incremental change.
Small steps, one more unit, one more item, etc. 13

Incentives- something that encourages a certain type of behavior. 14

15. Incentives - Example
For instance if I offered you an A in this class for $5, many of you would pay me.
