Perfect Competition:
The Most Efficient Market
  Dominic, Andrew, Connie, and Jessie
What Is Perfect Competition?
All firms...
 • Sell an identical product
 • Are price takers
 • Have relatively small market share
 • Let their buyers know everything about a
    product/service
 • Have the leisure of entering or exiting the
    industry
What Is Our Business?
•   On campus “lounge area”

•   We keep down our costs

•   Perfect competition pushes us to provide the best
    possible service

•   We compete against Cezar’s Kitchen

    •   We want to take a chunk of their market share
Perfect Competition:
 Firm and Industry
  •   Movement of firm reflects movement of industry and vice versa

  •   The AR curve = MR curve

      •   Firms are price takers therefore, if one firm raises the price, consumers will
          move to other firms

      •   Creates a horizontal constant curve and no marginal revenue

  •   AR = MR = Demand

      •   Demand shows how many consumers buy at varying prices, a mirror of
          what AR shows
Supernormal (Abnormal) Profits
      • Any profit above normal profit
      • Short run
      • Because “perfect”, other firms will be
        able to sell for the same amount so
             they would soon be able to sell at the
             same price

         •   Long Run

             •   Normal profit

         •   Bring average cost curve back to
             demand curve at normal profit

         •   This “perfect” nature creates efficiency
Loss in Perfect Competition

•   Demand fall results in price fall

•   Experiencing loss since AR < AC

•   Reflects entire market

•   As firms lose money, some firms leave the market

•   Results in shift in supply curve
Downsides of Perfect
   Competition
  • Low profits for investment
  • Not much product variety
  • Externalities may cause problems
  • Possible unequal distribution of goods &
    income
Upsides of Perfect
               Competition
• Optimal allocation of resources
• Competition gives incentive to work
  harder
• Consumers have influence over prices
• Business responds to consumer wishes
