Economic Tools and
Economic Systems
These slides supplement the
textbook, but should not
replace reading the textbook
What is
opportunity cost?
The value of the best
alternative forgone
when an item or
activity is chosen
2
How is opportunity
cost estimated?
Opportunity cost is
subjectively estimated
by the individual
decision maker
3
What is the opportunity
cost of a city to use local
taxes to pay for a park?
The best alternative
foregone by not
building the park
4
What is your
opportunity cost of
attending college?
If make $300 a week, but you
expect you could make $500
without school - your
opportunity cost is $200
5
What is the
opportunity cost of
cleaning your room?
It’s greater on sunny days
than on rainy days
6
Why is opportunity
cost subjective?
 calculation requires time and
information
 time is the ultimate restraint
 may vary with circumstances
7
What is a sunk cost?
A cost that is irrelevant
when an economic
choice is being made
8
What is an example
of a sunk cost?
The $6.75 you pay to
watch a boring movie is
irrelevant to whether or
not you watch it to the end
What is
absolute advantage?
The ability to produce
something with fewer
resources than other
producers use
10
You can paint a room in
2 hrs, a high school
student in 3 hrs, who has
absolute advantage?
You do because you
can do it faster
11
What is
comparative advantage?
The ability to produce
something at a lower
opportunity cost than
other producers face
12
You can make $50 an hr,
the high school student
makes minimum wage,
who should paint?
The high school student
because of a lower
opportunity cost
13
What is barter?
The direct exchange of
one good for another
without using money
14
What is a
division of labor?
The production of a
single good into
separate tasks in which
people specialize
15
What is a
specialization of labor?
Focusing an individual’s
efforts on a particular
product or a single task
16
How does the
specialization of
labor increase
productivity?
17
 Takes advantage of
individual natural abilities
 Allows workers to develop
more experience at a
particular task
 Permits the introduction of
labor-saving machinery
 Reduces time required to
shift between tasks
18
What is the production
possibilities frontier?
A curve showing all
combinations of
goods that can be
produced when
resources are used
most efficiently
19
What is efficiency?
The condition that exists
when there is no way
resources can be
reallocated to increase
the production of one
good without decreasing
the production of another
20
What assumptions
do we make with the
production
possibilities model?
21
 Output is limited to two
classes of products
 Focus is on production
during a given time period
 Available supplies of
resources are fixed
 Technology is constant

23
What is the law of
increasing opportunity?
As more of a good is
produced, larger
quantities of another
good must be sacrificed
if resources are already
used efficiently
24
What shifts the
production
possibilities frontier?
Changes in resources
Increase in the capital
stock
Technological change

What is true along the
production
possibilities curve?
 resources are used fully
 maximized division of labor
 most efficient combination
of resources
30
What choices are made
along the production
possibilities curve?
To have more of one
product units of the other
have to be given up

32
What is an
economic system?
A set of social institutions
and mechanisms
organized to answer the
three economic questions
33
What are the three
questions?
Who gets what
and how much?
34
What is
pure capitalism?
An economic system
characterized by private
ownership of resources and
the use of prices to
coordinate economic activity
in unregulated markets
35
What is a
command economy?
An economic system
characterized by public
ownership of resources
and centralized
economic planning
36
What is a
mixed capitalist economy?
An economic system
characterized by private

regulated, others are not
37
What kind of economic
system do we have?
A mixed capitalist economy
