Welcome to Economics
Topic 1: Fundamentals of Economics

2. Topic Objectives Students will be able to
Explain why scarcity and choice are the basis of economics in every society.
Describe the three economic factors of production and the differences b/w physical and human capital.
Explain how scarcity affects the factors of production
Identify why every decision involves basic trade-offs
Explain the concept of opportunity cost.
Describe how people make decisions by thinking at the margin.
Interpret a production possibilities curve.

3. What is Economics?
Economics- the study of how individuals, businesses and governments make choices when faced with a limited supply of resources

4. Scarcity and it’s impact on economics
Scarcity forces us to make choices, we cannot have everything
Needs
Wants

5. Businesses have goods and services
There is no way to solve the scarcity problem
Businesses provide either goods or services

6. Entrepreneurs Impact on Economics
Entrepreneurs are people who decide how to combine resources to create new goods and services
Entrepreneurs have different tasks:
Factors of production- resources needed/used to make all goods and services
Land
Labor
Capital
Physical capital
Human capital

7. Section 2: Opportunity Cost and Trade-Offs

8. What is an Opportunity Cost?
Opportunity Cost- the most desirable alternative somebody gives up as the result of a decision
Example: Going to Sports Night practice or going to a teacher’s extra help- which would be the best decision for you?

9. What is a trade-off?
A trade off is the act of giving up on one benefit to gain another, greater benefit
Usually involve things that can be easily measured, such as money, property, or time
Can also include things that cannot be easily measured
Can be applied to individuals and businesses
Guns or butter- describes one of the common choices facing government: the choice between spending money on military or domestic needs

10. Thinking at the Margin
Thinking at the margin: the process of deciding how much more or less to do
People have to decide the opportunity costs and benefits
Thinking at the margin applies to not only businesses but also to individuals and government
Example: Legislatures think at the margin when deciding how much to increase spending on a government program
Decision makers have to compare the opportunity costs and benefits: what will sacrifice and what will gain
Decision making process is sometimes called cost/benefit analysis

11. Cost/benefit analysis
Cost/benefit analysis is the examination of what will be sacrificed and what will be gained
A decision making process in which you compare what you will sacrifice and gain by a specific action.
Marginal cost- the extra cost of adding one unit
Marginal benefit- the extra benefit of adding the same unit
**As long as the marginal benefit exceed the marginal cost, it pays to add more units

14. Section 3: The Production Possibilities Curve
The Production Possibilities Curve is used to decide what and how much to produce
It is a graph that shows alternative ways to use an economy’s productive resources
The graph can show how effective an economy is, whether an economy is growing and the opportunity cost of producing more of one good or service

17. Production Possibilities Frontier
Production Possibilities Frontier is a line in the production possibilities curve that combines the production of two different products
Each point on the production possibilities curve frontier reflects a trade-off
These trade-offs are necessary because factors of production are scarce
Using land, labor, and capital to make one product means that fewer resources are left to make something else
Any point inside of the production possibilities frontier indicates underutilization
Underutilization- use of fewer resources than the economy is capable of using

18. Efficiency
Efficiency- the use of resources in such a way as to maximize the output of goods and services
Rise in a factor of production increases the maximum amount of goods the nation can produce
When the economy grows, economists say that the production possibilities frontier has “shifted to the right”
Law of increasing costs- principle that states that as production shifts from making one item to another, more and more resources are necessary to increase production of the second item
Opportunity cost increases

20. Enduring Understandings
Economics is the study of how people seek to satisfy their needs and wants by making choices among scarce resources.
Every economic decision involves trade-offs; the most desirable choice given up is the opportunity cost.
Production possibilities curves show how efficiently an economy uses its resources.
