Cycle 1, Day 1
2. Class Rules
Be on time
Pay attention
Be prepared
Don’t use cellphones
• Comments
• You are responsible to monitor your grade
• You are responsible to seek help (e-mail is best
way to contact me)

• Reviewing the Class Presentations (posted on
my faculty webpage)
• Getting the homework assignment, reading
assignment, etc.
4. Absences (continued)
Tests…
You need will make-up the test at detention when you
return.
You will receive a ZERO if you have not made
arrangements and I return the test.
E-mail is the best way to make arrangements to take the
test.
7. Economics is….
The study of human behavior. How people
allocate limited resources to produce goods
and services to satisfy unlimited needs and
wants.
Remember…resources are always scarce, always limited
9. Four Factors of Production (resources)
1. Land
All Natural resources
Example - Oil, Coal, Trees
2. Labor
People producing a good or service
Example – Auto worker, Lawyer, Teacher
3. Human Capital
• Training for Labor
Example – College Education, Seminars
4. Physical Capital
Tools used by labor to make goods and services
Example – Computers, Buildings, Factories, desks
10. Key terms
Scarcity vs. shortage
Need vs. want
Good vs. Service
Trade-off vs. Opportunity Cost
Entrepreneur
12. Need vs. Want
Need = gotta have it
Want = nice to have it
For each person to decide
Cellphone example
13. Good vs. Service
Good
• Tangible
• Generally produced with physical skills
• Examples….a car, a desk, an airplane
Service
• Intangible
• Generally produced with knowledge
• Examples…Medical services, legal services, education
14. Trade-off vs. Opportunity Cost
Trade-off = All the choices given up
Opportunity Cost = Most valuable choice (trade-off)
given up
Example….your time
18. Entrepreneur
Uses resources (factors of production) to
produce goods and services to satisfy needs
and wants
Examples
La Salle HS
Jack FM
Bank ATM
Amazon.com
19. Quick Review…
1. What is the difference between a shortage and scarcity?
(a) A shortage can be temporary or long-term, but scarcity
always exists.
(b) A shortage results from rising prices; a scarcity results
from falling prices.
(c) A shortage is a lack of all goods and services; a scarcity
concerns a single item.
(d) There is no real difference between a shortage and a
scarcity.
2. Which of the following is an example of using physical
capital to save time and money?
(a) hiring more workers to do a job
(b) building extra space in a factory to simplify production
(c) switching from oil to coal to make production cheaper
(d) lowering workers’ wages to increase profits

27. Production Possibilities Curve
Graph showing the trade-offs (i.e. possible production outcomes).
Trade offs is a key concept. More of one good or service, less of
the other.
Product (good
or service) B
Product (good or service) A
30. Production Possibilities Curve
Why is the production possibilities curve
“bowed out”?
ANSWER: The Law of Increasing Opportunity Costs
As you produce more of one product (Good or Service A),
the cost (opportunity cost) increases.

A production possibilities graph shows the cost of producing more of
one item. To produce four million more shoes (move from point c to
point d) is a cost of 3 million pairs of shoes. The Trade Off (the
real cost) of producing four million more shoes (to go from 14 to 18)
is the three million tons of watermelons that you give up (going from
12 to 9)

ANSWER: 200,000 tons (1/5 of a million) of
watermelons
37. Law of Increasing Costs…Revisited
The Law of Increasing Opportunity Costs - As you
produce more of one product (Good or Service A),
the cost (opportunity cost) increases.
The cost of first million shoes cost
200,000 tons of watermelons
The cost of the fifteenth million (still one
million shoes) cost five million tons.
THE COST INCREASED
39. Law of Increasing Costs…Continued
Why is that the case?
Because the entrepreneur uses the best
shoe making resources (factors of
production) for making shoes first…the
worst is used last.

Efficiency means
using resources in
such a way as to
maximize the
production of goods
and services. An
economy producing
output levels on the
production possibilities
frontier is operating
efficiently.

Growth If more
resources become
available, or if
technology improves,
an economy can
increase (more stuff) its
level of output and
grow. When this
happens, the entire
production possibilities
curve “shifts to the
right.”
