REVIEW
Scarcity and its effects
• All resources are scarce
• Productive resources (factors of production)
–
–
–
–
Land
Labor
Capital
entrepreneurship
• Scarcity leads to 3 questions:
– What to produce
– How to produce
– For whom to produce
Scarcity and its Effects Cont’d
• Different economic systems answer the three
basic economic questions differently
– Command Economy – government makes all
decisions (North Korea)
– Free-Market Economy – producers and consumers
make the decisions (no true free market systems in
existence)
– Mixed-Market Economy – producers and consumers
make the decision with guidance (regulation) from the
government (United States)
Role of Government in a Market
(U.S.) Economy
• Provide public goods and services
• Redistribute income to meet needs of poor
– (collect money through taxes and redistribute through
welfare programs)
• Resolve market failures
– Use of Fiscal Policy (taxes and spending)
– Use of Monetary Policy (actions by the Federal
Reserve)
– Regulations to protect property rights of citizens
– Deregulation – allow businesses to operate in free
market
Fundamental Concepts Cont’d
• Scarcity forces us to make choices
– Results in opportunity costs, trade-offs or engaging in
voluntary trade
• used when parties feel that will benefit (gain) from the trade
• Basis of U.S. economy
• Rational Decision Making Model
– Define the problem
– List the alternatives
– Evaluate the alternatives (compare opportunity costs
and benefits)
– Make a rational decision
Production Possibility Curve (Production
Frontier)
– shows production efficiency (b,c,d) underutilization (a)
and impossibilities (x)
Fundamental Concepts
• Specialization, division of labor, increased
labor force and investment in education,
training, technology, and resources
increases productivity and improves
efficiency
– All of these lead to economic growth and
improved standards of living

Questions
•
trees, minerals and the real estate on which a company builds its main
manufacturing center are all __________.
•
Following a massive storm, people buy up all the flashlights and bottled
water in the area faster than the producers can resupply them. The people
in the area now face _________ regarding the flashlights and bottled water?
•
Paying for an employee’s health insurance is a way of investing in
_________ __________ to increase production possibilities.
•
Using a production possibility curve, a company can determine the
______________ _________ of increasing production of one product over
another
MICROECONOMIC CONCEPTS
Circular Flow Model
• Three economic actors: households (individuals),
businesses (firms) and government
• Individuals provide labor and other factors of production
to businesses in exchange for money (wages/income)
• Businesses provide goods and services to households in
exchange for money (revenue)
• Government uses taxes from households and
businesses to provide services and money (transfer
payments/subsidies) to households and businesses
DEMAND

MICROECONOMIC
CONCEPTS
• Product Market where consumers
purchase final goods/products
• Factor Market where businesses hire
their labor and buy the goods needed to
produce their products
Microeconomic Concepts
Cont’d
• Fiat Money – represents value – has value
because the government says it does
• The Role of Money
– Medium of exchange
– Standard of value
– Includes paper and coins
– Includes transactions such as online
transactions, debit card transactions, online
stock trades
Microeconomic Concepts
Market Influences
Supply
• Supply – willingness and ability of a producer to provide
goods/services to consumers (aggregate supply)
• Law of Supply – As price increases, quantity supplied
increases
• Represented by an outward and upward shaped curve
on a graph
Supply
• Shift in supply refers to the change in total
supply, not the quantity supplied
Shifters of Supply
•
•
•
•
•
•
Availability of resources
Number of sellers
Technology
Government action (excise tax/subsidy)
Opportunity cost of alternate product
Expectations for future products
Demand
• Consumers willingness and ability to purchase a product
(aggregate demand)
• Law of Demand: as price decreases, quantity demanded
will increase
• Represented by a downward and outward sloping curve
Shifters of Demand
• Shift in demand refers to a total change in
demand, not just quantity demanded
Shifters of Demand
• Number of Consumers
• Tastes and Preferences
• Price of Related Goods
(substitutes/complements)
• Income (normal & inferior goods)
• Future Expectations
• Changes in PRICE don’t shift the curve. It
only causes movement along the curve
Supply and Demand
Price
• Equilibrium Price
– Quantity demanded equals quantity supplied
– Also known as Market Clearing Price
– Prices below equilibrium will result in a shortage
– Prices above equilibrium will result in a surplus
• Price Elasticity
– Sensitivity to price
– Price elastic – demand changes as price changes
– Price inelastic – demand does not change
significantly as price changes (steep almost vertical
demand curve)
Inflation and Interest Rates
• Inflation – general rise in prices throughout the economy
– Increased productions costs
– Increased prices
– Decreased demand
– Decreased supply
• Interest Rates
– Amount paid to borrow money
– High interest rates
• Fewer loans
• Decreased demand
Government Action
Wage and Price Controls
• Wage Controls
– Minimum wage – lowest wage employers can pay
their employees
• Pros and Cons
• Price Controls
– Price Ceiling – highest price producers can charge
• Set below equilibrium
• Causes shortages
– Price Floor – lowest price producers can charge
• Set above equilibrium
• Causes surpluses
Microeconomic Concepts
Competition
Market Competition

competition and the other is VERY
competitive

Competition
Competition
Perfect
Oligopoly
Monopoly
Pure Competition

Producers have more control over price
Examples: fast food chains
Oligopolies
• Only a few producers

at levels that increase profits w/o causing
inflation, national debt shrinks (or at least stays
level)
