A. Factors of Production
Anything fixed (natural resources)
Physical and mental talents
Something physical to aid production (factories, computers, an
educated/trained labor force)
Initiative, risk taking, innovation
B. The Production Possibility Frontier
measures how many of two types of goods can
Static Model (time is
constant, inputs are fixed)
a. Consumer goods such
as televisions, pizzas, and social security bring current
b. Capital goods such as
machinery, tractors, and improved technology increase
future productive capabilities.
c. Point F on the
production possibility frontier represents full employment of all resources
d. Point U represents
unemployment of some economic resources.
e. Having more capital
goods requires giving up some consumer goods.
f. Applies to individuals

d. Politicians seldom talk of the
opportunity cost of what they plan to do.
The opportunity cost of good grades is the value which could have been received by
spending time with family and friends.
The opportunity costs of more capital goods is the value
which could have been received from having more consumer
Law of increasing opportunity costs
a. Opportunity costs usually increase.
1. To have one unit of
Item A you must give up amount X of Item B. To have a
second unit of Item A you must give up more than amount X
of Item B.
Primary reason for increasing costs is resources are not perfect substitutes.
Training more people in math and science would increase productivity
for a while but eventually people would be
trained to be
engineers who would be more productive as managers, teachers, or
b) Gains from replacing people with machines may be large at
first but eventually machines would be used to do
what people can do
opportunity costs are not increasing, the production possibility
curve is a straight line.
High tech investment may even bend the
curve the other way and have decreasing cost, but not forever!

Adam Sandler, a great entertainer, probably would not of been a
great computer programmer,
dad Stan was an electrical engineer, his sister Elizabeth a dentist,
and his brother a Scott a lawyer.
Adam might be the
first resource to move to creat more production.
Characteristics of Market System
Entire Chapter 3
A. Economic systems determine what to produce, how to produce,
and who will receive production.
B. An economic system must also adapt to changing economic environments.
For example, America
must adapt to changes to September 11?

structures based on technology and the
destruction of inefficient economic structures.

and Supply Review View
Entire Chapter 4
A. A market is defined
as an institution or mechanism which promotes trade
by bringing together buyers (demanders) and sellers
1. Replaced barter which is the direct exchange of
2 Modern market brings money and prices into the
circular flow of goods.
B. Demand is willingness to buy.
1. Demand is a
schedule of the amounts of goods and services consumers
are willing and able to buy at a set of prices.
2. Total demand is the Horizontal
3. Law of demand:: price
and quantity are inversely related and as price goes up,
quantity demanded goes down and vice versa
4. Why more is bought as price drops.
Effect: as price drops, consumers feel richer and buy more.
Effect: as price drops, it becomes cheaper relative to
other goods and consumers buy more
C. What determines demand
or preferences of consumers
Number of consumers
Incomes of consumers
such as steak and vacations - more is purchased as income
goods such as bread and hamburger
- less is purchased as
Price of related goods
are goods that compete with each other such as hot dogs
If the price of a good increases, the demand for its substitutes will increase.
are goods that are purchased together like
hot dogs and rolls.
If the price of a good
increases, the demand for its
complement will decrease.
is Latin for all other variables remain the
same. So we change one variable at a tome.
D. Changes (shifts) in Demand
1. A decrease in demand shifts the demand curve to the left
2. An increase in demand shifts the demand curve to
E. Supply is willingness to sell
1. Supply is a schedule of the amounts of
goods or services producers are willing and
able to sell at a set of prices.
2. Law of supply:
price and quantity supplied are directly related because price and
profit are directly related
As price goes up, quantity supplied goes up
As price goes down, quantity supplied goes down
F. What determines supply
1. Product costs
as affected by technology, resource prices, government involvement with taxes
2. Price of related goods
a. If 2
goods are substitutes, price up for one will increase supply of the other (price of gasoline up,
supply of alternative
fuels increases) as
companies see more potential profit
b. If 2
goods are complements, price down of one will increase supply of other (price of PC's
supply of computer software up) as the
expected increase in sales of the first item should increase
sales of the
3. Number of producer
and their expectations concerning the
above listed variables will affect supply
G. Changes (shifts) in supply
1. A decrease in supply shifts the
supply curve to the left
2. An increase in supply shifts the
supply curve to the right
H. Equilibrium is where suppliers and demanders agree
on price and quantity as depicted
1. If the price is too high, a surplus results
and price must be lowered
2. If the price is too low, a shortage results.
This happens with toys every Christmas
(Cabbage Patch Dolls)
3. If they can not agree, as happened with
Beta videotape machines,
then the curves do not intersect
and the goods are not sold.
4. Rationing function of price
makes for an efficient allocation of resources.
Whencompetitive forces of supply and demand result in an
rationing function of
goods produce to
consumers has occurred.
I. How changes in supply and demand affect equilibrium price and quantity6
J. Government Imposed Price Ceilings and Floors
1. A price ceiling keeps prices from rising (rent
control) helping renters but often
resulting in a
shortage of housing as
investors seek higher returns elsewhere.
2. A price floor keeps prices
from falling (farm price supports)
though a surplus often results as more of supported crops are
V. 5 Key Questions Society Must Answer Review
View Entire Chapter 5
A. What to produce?
1. Which goods
Those that can be sold at a profit, consumers vote with dollars
Profit: The amount by which total revenue exceeds
accounting costs (rents,
wages, and interest)
1. Amount received for enterprise
2. Considered by economists to be a cost
The amount by which total revenues exceed all "Factor" costs.
think of it as a surplus.
Expanding industries have economic profit.
a) Bill Gates, founder of Microsoft, has earned many billions
b) So has Sam Walton of Wal-Mart
2. How many goods
Level of demand and efficiency of supply determine output.
Society determines total demand (who works, how often and
for how many years).
Success of economic system determines efficiency of supply.
B. How to produce?
1. Companies must be competitive
2. Competition is the "Invisible
a. High quality
goods are produced.
production methods are employed.
c. Prices and profits are reasonable.
d. For more

3. Technology and innovation are
instrumental to success.
C. Who will receive production?
1. Those willing and able to
2. Function of income, savings,
and attitude toward debt financing
D. How will the economy adapt to changing environments?
1. Today's economic
environment is changing more rapidly because
of the communication
2. Magnitude of these changes is similar to
that which occurred in the
last quarter of the 19th century.
3. Companies and individuals must "adapt or be
4. Capitalism allows creative destruction to
5. Recently technology has changed rapidly and people
a. Normally, political forces
would attempt to slow creative destruction.
b. But, the 1990's was the
decade of free enterprise so creative
destructions moved on.
c. Perhaps the next recession
will slow down the free market
E. Market system evaluated
1. Advantages are resources allocated efficiently,
economic freedoms (enterprise,
dependent upon competition eroded by monopoly power resulting in waste
result because of monopoly power exercised by business,
unions, governments, and interest groups.
Inequitable distribution of income (economic survival of
all costs (pollution) and benefits (public health) are properly accounted
because measuring their cost and benefits in dollars is difficult and
Political process sometimes interferes with creative destruction.
Government's Economic Function

a proper legal atmosphere (rules) for capitalism
B. Insure competition
1. Antitrust laws
protect against abuse of monopoly power.
(justifiable) monopolies such as AT&T were allowed because
duplicating high-cost fixed investments is illogical.
3. The emphasis on free markets discussed
in chapter 3 has resulted in some natural
monopolies being broken into smaller companies which had to
new companies touting new technologies.
C. Provide for an equitable distribution of income
payments where a government moves general revenue to a
specific group, i.e., Aid to Families with Dependent Children,
2. Market Intervention
(affecting supply and demand)
Minimum wage decreases supply raising price and lowering quantity.
taxes on alcohol, cigarettes, jewelry, etc., deceases supply.
price supports, aid to small business and education increases supply.
D. Adjust for market failures
1. Adjust for spillovers
a. Effects of a market
system often spillover onto non-participants who are
external to the market
Both costs and benefits result.
1. Pollution hurts (costs) society so government tries to affect
the supply of,
and demand for, pollution causing products such as automobiles.
For automobiles, they lower supply by requiring catalytic converters and
lower demand with high excise taxes.
2. An educated workforce benefits society so government increases demand
