  • Supply and Demand Unit 4: Microeconomics
  • I. Demand
  • A. Description
      • Demand is the desire to own something and the ability to pay for it.
      • Law of demand:
    PRICE As price goes down… DEMAND Quantity demanded goes up. PRICE As price goes up… DEMAND Quantity demanded goes down.
  • B. Changes in Demand
    • Substitution Effect: $ , the demand will be effected by substitutes available.
    • Substitutes are goods used in place of another.
    • 3. Income effect: Income rises, the demand will be effected in two different ways:
      • Normal goods: If wealthier, they will buy more of.
      • Inferior goods: If wealthier, they will buy less of.
    • Consumer expectations: Customers know there is a sale, they will not buy this week.
  • 5. Population: Population changes in age, goods demanded change.
  • 6. Tastes and advertising: Waves of popularity & advertising will impact demand.
  • 7. Related goods: Complements are goods that are bought together.
  • C. Extreme Demand
    • Supply shock is when there is a severe shortage.
  • 2. Government may intervene with rationing
  • a. WWII is an example of high demand, rationing rubber, fuel, nylon, etc.
  • b. 1970’s: Gasoline rationing.
  • II. Supply
  • A. Description
    • Production
    • Law of Supply:
    Prices go up… Supply goes up. Prices goes down… Supply goes down.
  • B. Changes in Supply
    • Rising Costs: Costs of production will cause a decrease in supply.
  • 2. Technology: Efficiency in production will increase production and supply.
  • 3. Subsidy: Government financial assistance for producers.
  • 4. Excise tax: Tax on the production, distribution, sale of product.
  • 5. Regulation: Limits on the production will decrease supply.
  • III. Supply and Demand Together
  • A. Equilibrium Equilibrium Price Surplus Shortage Demand Supply Price Floor : Minimum Wage Price Ceiling: Rent Control
  • B. Elasticity
    • Elasticity of demand: Sensitivity of demand of consumers to price change.
  • 1. Elastic: Items that are highly sensitive to price change.
  • 2. Inelastic: Items that are not sensitive to price.
  • 3. Elasticity of supply: Sensitivity of suppliers to price change.
  • a. Elastic: Suppliers will be able to produce more or less of a product due to changes of prices in the market.
  • b. Inelastic: Suppliers will not be able to produce more or less of a product.
  • C. Companies and Pricing
    • Suppliers must take into account, the bills they have when producing:
  • 1. Fixed Costs : Same monthly.
  • 2. Variable Costs: Varies monthly.
  • 3. Fixed + Variable = Total
  • 4. Adding labor (more workers is not always good):
  • a. At first, each additional worker increases output more. (Increasing Marginal Returns)
  • b. Eventually output will still increase, but more slowly. (Diminishing marginal returns).
  • c. Soon, production will drop with each worker added. (Negative marginal returns).
  • IV. Market Structure
    • A. Organizational Chart

  • D. Perfect and Monopolistic Competition
    • Perfect competition is tough market
    • Farmers are example, make little profit
    • Monopolistic competition fare better due unique twist they have on product.
  • E. Monopolies and Oligopoly
    • Monopolies virtually banned by Anti-trust Laws
    • Natural Monopolies still exist
      • Geographic – last gas station for miles
      • Governmental – only cable company allowed in town
      • Technological – patents for new products
    • Oligopoly companies are forbidden from cooperating with each other (collusion)
