1. Economic Choices and Decision Making
1.3

2. Introduction
Because resources are scarce, businesses and consumers need to make wise choices.
Trade-offs are the alternative choices people face in making an economic decision.
Thinking on the margin, or MARGINAL ANALYSIS, involves making decisions based on additional benefit vs. additional cost

# Times Watching Movie
Benefit
Cost
1st
$30
$10
2nd
$15
3rd $5
Total
$50
Would you see the movie three times?
Notice that the total benefit is more than the total cost but you would NOT watch the movie the 3rd time.

4. Trade-Offs and Opportunity Cost
Opportunity cost is the cost of the next best alternative among choices. The opportunity cost is the money, time, or resources a person gives up to make his final choice.

5. Trade-Offs and Opportunity Cost
Opportunity costs are experienced when trade-offs are made.

7. Production Possibilities
The Production Possibilities Frontier is a graph that shows the various combinations that can be produced when all resources are used. In short, it shows us the opportunity costs of producing each product.

12. Production Possibilities Frontier
The line on the graph represents the full potential (the frontier) - when the economy employs all of their productive resources.

13. Production Possibilities Frontier
Economic growth is needed for “C”
more resources
a larger labor force
increased productivity

14. Production Possibilities Frontier
An economy pays a high cost if any of its’ resources are idle:
It cannot produce on its frontier and it will fail to reach its full production potential.

16. Thinking Like an Economist
Building simple models like the PPF helps economists analyze or describe actual economic situations.
Cost-benefit analysis helps economists evaluate alternatives by looking at each choice’s cost and benefit.

It helps us understand a free enterprise economy, where people and privately owned businesses rather than the government make the majority of the economic decisions.
