Georgia Performance Standard
SSEF1 The student will explain why limited productive resources and unlimited wants
result in scarcity, opportunity costs, and tradeoffs for individuals, businesses, and
governments.
c. List a variety of strategies for allocating scarce resources.
d. Define opportunity cost as the next best alternative given up when individuals,
businesses, and governments confront scarcity by making choices.

comparing the marginal benefits and the marginal costs of an action.
b. Explain that rational decisions occur when the marginal benefits of an action equal or
exceed the marginal costs.
SSEF6 The student will explain how productivity, economic growth, and future
standards of living are influenced by investment in factories, machinery, new
technology, and the health, education, and training of people.
b. Give illustrations of investment in equipment and technology and explain their
relationship to economic growth.
c. Give examples of how investment in education can lead to a higher standard of living.

What is a Rational
Decision?
Rationalconsistent with
logic; sensible
Opportunity
Cost- the next
best
alternative
A rational decision is not just a decision made by
evaluating all choices, it is a decision that takes into
account the reason for making the decision.
Decisions should be made taking individual and national
goals into account because of scarcity.
– Scarcity is the concept that people and
countries have unlimited wants but limited
resources. This forces people to make choices
and when you make a choice, there is always a
cost.
Whether it is a country, a business or an individual, every
time a choice is made there will be an opportunity cost.
This is why making a ration decision is so important.
Micro Example
Microeconomics- the
study of decision
making and behavior
of individuals and
firms
Kristina just won $1000 check from an essay contest. It is almost summer and
the first thing that came to her mind was to take a vacation with the money,
but she does have other options. She is going to college in the Fall and her
car needs breaks and new tires.
How should Kristina make a rational decision with her resources?
Things to consider:
• Goals
• Current situation
• Important Criteria for the results you desire
• The cost and benefit of each decision
Micro Example
Kristina just won $1000 check from
an essay contest. It is almost
summer and the first thing that came
to her mind was to take a vacation
with the money, but she does have
other options. She is going to college
in the fall and her car needs breaks
and new tires.
Answer the following Questions:
cont..
1.
What are Kristina’s wants? What
are her limited resources?
2.
If you were in Kristina situation,
what would be your top 4
options for spending the
money?
3.
How would Kristina explain
choosing to go on vacation with
the money?
4.
How would Kristina explain
spending the money to fix up
her car?
Decision Making Grid
One tool that can be used to evaluate decisions using important criteria is
a decision making grid.
1. List your top 4 choices
2. Determine the criteria important to your current goals and/or situation
(list criteria in order of importance)
3. Complete the chart by checking the criteria box if the answer is yes

Can you think of other tools or
methods you can use to make
rational decisions?
More Methods
Another way to make a rational decision is to do a cost benefit analysis.
Imagine in Kristina’s case that she couldn’t decided to buy the computer or
the car repair. That both of them were equally desirable. How should she
choose between the two?
If both options are equally beneficial but the car repair was $500 and the
computer was $650, then Kristina should pay for the car repairs because she
gets the maximum benefit for the lowest cost.
Assessment - Complete one of the following:
1. Write an example of when you have used cost benefit analysis.
2. Use the decision making grid to analyze a choice you will have to make
soon.
Macro Example
Macroeconomicsthe study of the
economy as a whole
and decision making
by governments and
large units
Every country faces the problem of scarcity. Countries have limited resources but their
people have unlimited wants so a choice must be made. Consider the following
example:
In the 1950’s the US government(and the UN) were asked by South Korea to send
troops to help them fight Communism. The country was in the midst of a Cold War,
and ideological battle between Democracy and Communism and our policy at the time
was to try to contain Communism as we felt it was a very dangerous threat. There
were also domestic issues the country was facing. The post war baby boom made it
necessary to provide education to an increased population of youth and since the Cold
War was fought through intelligence, there was a real constant threat of spies trying to
steal national secrets and technology.
EXPLAIN YOUR DECISION
If you were the President of the United States, what criteria and
information do you need to consider in order to make a rational
decision?
How will you justify your decision to the American people?
Write a speech:
As if you were the President of the United States.
Explain to the people how you have decided to use
the country’s resources, what it will cost them and
why it is worth it.

of profit or
material result
Allocatedistribute for a
specific purpose
Standard of
living- quality of
life based on the
level of wealth,
happiness,
comfort, material
goods and
necessities

For both individuals and governments the key to growth is
investment. Goals should always be involved in the equation
when making decisions. Allocating resources to education,
technology and equipment can lead to increased growth in the
future.
• For the individual and the business this can mean a higher
income or more profit.
• For governments this can mean a higher standard of living
for the population.
