Microeconomic Concepts (Chapters 3, 4, 5, & 6)
SSEMI1, SSEMI2, SSEMI3, SSEMI4
- Demand – Desire and willingness to buy a product
- Individual + Demand / All Consumers + Market Demand
- Add all individual demands together
- Law of Demand – Price and Quantity move in opposite directions
- Downward Slope
- Change in Quantity Demanded (Shift on curve)
- Income Effect = price goes down, consumers left with extra real income.
- Substitution Effect + replace with cheaper but similar item.
- Change in Demand (Shift of curve)
- People buy different amounts of product at same prices
- Income, tastes, consumer expectations, # of buyers
- Price change of related product (substitution or complementary)
- Price Ceilings = maximum price that can be charged for a product
- Example: Rent Controlled Apartments
- Can Cause Shortage – price no longer dictates
- Elasticity of Demand = how sensitive consumers are to price changes
- Elastic = Change in price = Large change in demand
- Inelastic + Change in price = small change in demand
- Unit Elastic Demand + proportional
- Total Expenditures = Price times Quantity Demanded
- Fig 4.5 (page 103)
- Causes of Changes in Elasticity
- Can purchase be delayed?
- Available Substitutes?
- Portion of income needed for purchase?
- Diminishing Marginal Utility
- Supply – Amount of product sold at various prices
- Individual = Supply /All Producers = Market Supply
- Add all individual Supplies together
- Law of Supply – Price and Quantity Supplied move in same direction
- Upward Slope
- Change in Quantity Supplied (Shift on curve)
- Change in amount offered for sale in response to change in price
- Change in Supply (Shift of Curve)
- Cost of inputs, productivity levels, technology, taxes, subsidies (gov’t payment), expectations, gov’t regulations
- Price Floors – lowest price that can be paid for a good or service
- Example: Minimum Wage
- Could increase # unemployment
- Elasticity of Supply + how quantity supplied reacts to change in price
- Elastic = small increase in price = large increase in output
- Inelastic = small increase in price = little change in supply
- Unit Supply = proportional
- Production Theory = relationship b/w f.o.p. and output of goods and services
- Short run = can change only labor
- Long run = can change all f.o.p
- Diminishing Returns = output decreases the more workers are hired.
- Costs
- Fixed
- Variable
- Total
- Marginal
- Surplus & Shortage
- Supply and Demand Together
- Both Inelastic = Drastic change in price
- Only one inelastic = Small change in price
- Businesses & Liabilities
- Sole Proprietorship
- Partnership
- Corporation
- Entrepreneurs – Profit Incentive
- Monopoly
- Oligopoly
- Pure or Perfect Competition = 5 characteristics
- Monopolistic Competition

Microeconomic Concepts (Chapters 3, 4, 5, & 6)SSEMI1, SSEMI2, SSEMI3, SSEMI4
- Define microeconomics.
- The ______states that more will be purchased at low prices than at ____ prices.
- More will be purchased at low process than at high ones.
- Less will be purchased at low prices than at high ones.
- Approximately the same about will be purchased at low prices than at high ones.
- The demand curve is always sloping ______(upward/downward).
- All of the following must exist for there to be demand: _____, ______, & ______.
- How does the demand curve respond to an increase in demand?
- How does the demand curve respond to a decrease in demand?
- Define complements. Be able to identify a complement vs. a substitute and how each impact demand.
- Define elastic demand.
- The Law of Supply states:______.
- The supply curve is always sloping ______(upward/downward).
- How does a decrease in the price impact demand?
- How does an increased in government regulations affect the supply curve?
- The period of production is classified into two categories, long run & short run. Be able to identify both the long run of production and the short run of production.
- Define rationing and identify the characteristics of rationing.
- What is a shortage in the market? How does a shortage impact price?
- What is a surplus in the market? How does a surplus impact price?
- What is equilibrium price?
- Define price ceiling? Give 2 examples of a price ceiling. For the test be able to identify examples of a price ceiling.
- Define price floor? Give 2 examples of a price floor. For the test be able to identify examples of a price floor.
- What is a result of price ceilings being artificially low?
- What is a result of price floors that are artificially high?
- List all the shifters of demand. For the test, be able to determine how certain scenarios impact demand. For example, a great advertising campaign.
- Define perfect competition and the characteristics of perfect competition. For the test, be able to define and identify characteristics of the following business structures:
- Monopoly
- Oligopoly
- Monopolistic competition
- Pure competition
Hint: make and study flashcards for each.
- Define the following types of monopolies:
- A natural monopoly
- A geography monopoly
- A technological monopoly
Hint: make and study flashcards for each.
- Why are monopolies dangerous to consumers?
- Define market failure (positive and negative externalities).
- Define and identify public goods.
- What is public disclosureand how does it supports competition?
- Be able to identify shifters of supply. For example, new technology. Know how to determine what happens to supply if technology improves, technology fails, new regulations, deregulations etc.
