4Factors of Production(Productive Resources)
5GPS
- SSEF1 The student will explain why limited
productive resources and unlimited wants result
in scarcity, opportunity costs, and tradeoffs for
individuals, businesses, and governments. - Define and give examples of productive resources
(e.g., land (natural), labor (human), capital
(capital goods), entrepreneurship).
6Factors of Production
- What went into making this?
7What went into this?
Rubber (from Malaysia)
machines
metal
Someone who put all of this together.
wood
graphite
84 Categories of Productive Resources (Factors of
Production)
- LAND LABOR
- CAPITAL
ENTREPRENUERSHIP
- Natural, renewable resources
- wood, rubber, graphite, land, animals
- Human resources, people
- MENTAL and PHYSICAL
- A produced good used in the production of
another good - Machines, computers, buildings, etc
- The person or group responsible for putting the
other 3 together to produce something
9Opportunity Costs
10Opportunity Costs
- OPPORTUNITY COSTS the value of the NEXT BEST
alternative given up when a choice is made - NEXT BEST is key, the cost is not everything you
give up - Opportunity cost is not always money
11Opportunity Costs Examples
- Mr. Cannon really wants BOTH goods
3,500
1,000
12Opportunity Costs Examples
- He decides to spend his money on
3,500
What was the price he paid? What was his
opportunity cost?
13Opportunity Costs
- You have 100 to spend at the mall, rank the
following in the order (1, 2, 3) you would
purchase them. - DVD set of a TV Show(60)
- New outfit (85)
- New pair of shoes (65)
14Production Possibilities Curve (PPC)
15GPS
- SSEF2 The student will give examples of how
rational decision making entails comparing the
marginal benefits and the marginal costs of an
action. - Illustrate by means of a production possibilities
curve the trade offs between two options.
16PPC
- a graph that shows the trade-off between two
production options - A visual representation of OPPORTUNITY COSTS
- 2 Assumptions
- The company/country is ONLY producing the two
goods on the graph - The company/country desires to use ALL of their
resources
17PPC an example
- Suppose a country makes Pencils and Pens.
- If they devoted ALL of their resources to
pencils, they could make 500 a day - ..to pens, they could make 300 a day
500
300
18PPC an example
The country/business can produce anywhere on the
line when they use ALL of their resources
500
Pencils
Pens
300
19PPC an example
If the country is producing ONLY pencils, and
they want pens, they have to give up pencils.
500
450
Pencils
The more pens they want..

21Journal 5 Graph this countrys PPC
- After graphing, answer these questions
- Assume the country is currently producing 180 of
good A and 25 of Good B. If the country wants to
make 75 of Good B, how many of good A must they
give up? - If the country was producing 150 of Good A and 30
of Good B, what could you conclude about the
countrys economy?
GOOD A GOOD B
200 0
180 25
150 50
100 75
25 100
0 110
22Productivity and Investment
23GPS
- Define productivity as the relationship of inputs
to outputs.
24Productivity
- We measure productivity as the relationship of
inputs to outputs - For a business its the cost of all their
resources compared to their revenue - For a country its the cost of all of their
resources as compared to their GROSS DOMESTIC
PRODUCT (GDP)
25Improving Productivity
- Increased Capital
- More factories, tools, machines, etc
- Improve technology
- Faster machines, multi-tasking devices, machines
with larger capacity - Train/educate workers
- Specialization, new techniques, ability to USE
technology - Improve entrepreneurship
- Better organization of resources, motivational
tools, leadership, worker morale
26Headlines
- HEADLINE 1 WHIRLPOOL FACTORY INCREASES
PRODUCTIVITY - What are some steps the Whirlpool Factory could
have taken to increase productivity? - How could this increase in productivity benefit
the workers? - HEADLINE 2 U.S. PRODUCTIVITY RISES RAPIDLY FOR
6TH CONSECUTIVE QUARTER - How can rising productivity benefit workers?
Producers? The nation? - Could there be some disadvantages of increasing
productivity, at least to some people? - HEADLINE 3 PRODUCTIVITY LAGS FIRST THREE
QUARTERS OF 93 - Why is lagging productivity a problem for the
nation, businesses, and individual workers and
consumers?
27Economic Growth
28GPS
- Give illustrations of investment in equipment and
technology and explain their relationship to
economic growth. - Give examples of how investment in education can
lead to a higher standard of living.
29Economic Growth
- For countries, we look at economic growth in
terms of GROSS DOMESTIC PRODUCT (GDP) and GDP PER
CAPITA - GDP dollar amount of all goods and services
produced in an economy - GDP Per Capita GDP divided by the population
- What makes an economy grow?
30Factors Affecting Economic Growth
- High Investment in physical and human capital
- Greater economic freedom
- lower taxes, fewer regulations, protecting
property rights - Strong Incentives to Save
- Competitive Markets
- Political Stability
- Free Trade
31Historic examples

- lower taxes, fewer regulations, protecting
property rights - Strong Incentives to Save
- Competitive Markets
- Political Stability
- Free Trade
39Different PPC graphs can show how different
variables affect an economy.
40Different PPC graphs can show how different
variables affect an economy (continued).
- A natural disaster such as a hurricane has the
effect of Case 1 on a local economy. Here, both
capital (buildings and equipment) and labor are
lost due to the calamity. Since the regions
production inputs are reduced, so too is its PPC,
moving from A1 to A2. The region may recover over
time, but the immediate effect of the disaster is
to move the entire PPC inward. - Conversely, consider a local area with a booming
economy people are moving there in droves
(providing labor), and businesses are investing
in the area to take advantage of the increased
number of consumers and potential employees. This
would lead to a condition illustrated in Case 2,
where the entire PPC shifts outward.
41Different PPC graphs can show how different
variables affect an economy (continued).
- Now imagine a small town has just received a
large economic development grant from the federal
government. The amount of capital available to
this economy has greatly increased while its
labor pool remains unchanged, so a movement like
that shown in Case 3 occurs. The new PPC, C2,
shows how the investment will create an enhanced
ability to produce capital goods. Lastly,
increases in labor inputs (such as a higher
number of college graduates) will lead to Case 4.
Here, the boost to the labor force allows the PPC
to shift from D1 to D2.
42RATIONAL DECISION MAKING
43Rational Decision Making
- Analyzing costs and benefits before making a
decision - MARGINAL thinking is key
- What is the cost/benefit of my NEXT decision
- Past decisions dont matter
- this affects PRODUCERS AND CONSUMERS
- A rational decision is made when the marginal
benefit is equal to or greater than the marginal
cost
44Costs and Benefits
- For producers, this is simply measured in dollars
- Marginal costs of the inputs vs. marginal revenue
- For consumers, it is trickier
- We measure benefits in terms of UTILITY
- How useful is the item or service
- We use utils as the measure for this
45Another Example
- You purchased a ticket to see
- 10 minutes into the movie, you realize it is
going to be horrible. - DO YOU STAY OR LEAVE?
- Write down your answer and reason WHY.
46RDM Example (contd)
COST BENEFIT
STAY Lost opportunity to do next best thing See end of movie Can discuss movie with others
LEAVE Cant discuss with others Wont see ending Can do next best thing which may bring more satisfaction
47Another example
- A person opens a business making sandwiches.
Hes purchased a store and all of the food
products, now he wants to hire some people. He
decides to hire two people to start with and pay
them 50 a day. His costs/benefits sheet for a
month looks like this
481 Month
Rent/Food/Entrepreneurship 750
Worker Cost Production Price/Sand
1 750 250 sandwiches 5
2 750 250 sandwiches 5
Total Costs 75015002250
Total Output 500 x 5 2500
491 Month
Rent, Food, Entrepreneurship - 750
Worker Cost Production Price/Sand
1 750 250 5
2 750 250 5
3 750 200 5
4 750 100 5
Should he hire worker 3? Why? What about 4?

51Scarcity
52Georgia 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. - Define scarcity as a basic condition that exists
when unlimited wants exceed limited productive
resources. - Define opportunity cost as the next best
alternative given up when individuals,
businesses, and governments confront scarcity by
making choices.
53Scarcity
- SCARCITY a condition that exists when UNLIMITED
needs/wants exceed the LIMITED available
resources - The central problem in economics, all things
revolve around scarcity - Must be a want/need for the item and a limited
amount - There are DEGREES of scarcity
- If there is a lot of something that no one wants,
it is less scarce than something MANY people want
54MORE SCARCE - Small quantity, many
uses, high demand
LESS SCARCE - Large quantity, few
uses, low demand
55Scarcity Situations
- Old books that, for 2 years, have sat on a shelf
that reads Free! Take One. - Oil in Saudi Arabia
- One book, 5 students needing to study the book
for a quiz - Diamonds
- Oil in England
- A 10 bill to a millionaire
- An MVP basketball player
- A copy of Mr. Cannons tests
- VHS Tapes to a 10 year old
- Knowledge of Economics
56MORE SCARCE - Small quantity, many
uses, high demand
LESS SCARCE - Large quantity, few
uses, low demand
- Old books that, for 2 years, have sat on a shelf
that reads Free! Take One.
One book, 5 students needing to study the book
for a quiz
Oil in England
- A 10 bill to a millionaire
- A copy of Mr. Makayas tests
- VHS Tapes to a 10 year old
57Sample Questions for Unit 2
- 1 Opportunity cost is BEST described as the
- A most expensive resource used in production
- B sum of all production costs
- C value of the next best alternative forgone when
a choice is made - D monetary value of all alternatives forgone when
a choice is made
58Answer to 1
- 1. Answer C Standard Scarcity and opportunity
cost - Opportunity cost is the value of the next best
economic choice you did NOT make. Choice D is the
sum of all possible opportunity costs, but
opportunity costs are not added up. Only the best
alternative forgone, choice C, counts as the
opportunity cost.
592 Use this graph to answer thequestion.
60What BEST explains the shift of theproduction
possibilities curve fromB1 to B2?
- A improvements in agricultural technology
- B inflationary increases in process
- C higher costs of producing corn
- D higher costs of producing wheat
61Answer to 2
- 2. Answer A Standard Investment and economic
growth - An outward expansion of a production
possibilities frontier means greater
productivity. One way greater productivity can be
achieved is by improving technology.
62Question 3
- 3 Alex and Dylan mow and trim lawns. Currently,
each man mows and trims a lawn by himself, but
the process takes a long time. They would MOST
likely improve their efficiency if - A Alex and Dylan mow a lawn and then trim it
together - B Alex mows a lawn while Dylan trims the same
lawn - C Alex trims Dylans lawn while Dylan trims
Alexs lawn - D Alex and Dylan reduce the number of lawns they
mow and trim
63Answer 3
- 3. Answer B Standard Benefits of specialization
- One of the best ways to improve efficiency is to
specialize, which means each person in a
production process concentrates on a specific
task. Choice A would still require each man to
mow and trim, while choice C simply changes the
lawn each man is trimming. Choice D, on the other
hand, reduces the total number of lawns they mow
but does not improve the efficiency with which
they complete their task. Only choice B would be
a specialization of labor. In this case, Dylan
now does one task in the production process
(trims) while Alex does another task (mows).
According to economic theory, this specialization
will make each man better at his respective task
and reduce the time it takes to change from one
task to another, thereby increasing their overall
efficiency.
