    Study Notes

    Characteristics of Perfect Competition

    • Perfect competition is a market structure where individual firms have no influence over the market price.
    • Firms are price takers, meaning they cannot influence the price of a good or service.
    • The following conditions are necessary for perfect competition:
      • Large number of small sellers and buyers
      • Perfect substitutes (homogeneous products)
      • Perfect knowledge (all producers and consumers are aware of the market price)
      • Perfect mobility (free entry and exit of firms)
      • No collusion (independent action among buyers and sellers)
      • No external influence (government or other groups)

    Difficulties in Satisfying the Assumptions of Perfect Competition

    • In reality, it is difficult to achieve perfect competition due to:
      • Imperfect knowledge
      • Barriers to entry and exit
      • Differentiation of products
      • Imperfect mobility
      • Collusion among firms

    Relevance of the Perfectly Competitive Model

    • Despite its limitations, the perfectly competitive model is useful as a benchmark for evaluating the competitiveness of real-world markets.
    • It serves as an ideal or standard for judging the performance of firms in more typical market structures.

    Industries Close to Perfect Competition

    • Examples of industries that approximate perfect competition:
      • Foreign exchange markets
      • Stock markets
      • Commodity markets (e.g. copper, tin, corn, coffee, tea)
      • Electronic marketplaces (e.g. Amazon)

    Output Decisions under Perfect Competition

    • The individual firm in a perfectly competitive market:
      • Is a price taker
      • Has a perfectly elastic demand curve
      • Maximizes profit by producing where marginal revenue equals marginal cost
      • May earn supernormal profit or make a loss in the short run

    Deriving the Perfectly Competitive Firm's Supply Curve

    • The firm's short-run supply curve is the portion of the marginal cost curve above the average variable cost curve.
    • The firm's long-run supply curve is the marginal cost curve above the minimum long-run average total cost curve.

    Long-Run Equilibrium under Perfect Competition

    • In the long run, the firm earns normal profit or exits the industry.
    • The industry is in equilibrium when all firms earn normal profit.

    Perfect Competition and Economic Efficiency

    • Perfect competition leads to economic efficiency, which has two aspects:
      • Technical efficiency (producing at the lowest point of the average cost curve)
      • Allocative efficiency (producing at the level where price equals marginal cost)

    Perfect Competition and the Internet

    • The Internet has reduced market imperfections and increased competition by:
      • Providing wider choice to consumers
      • Allowing for easier price comparisons
      • Reducing transaction costs
      • Reducing the minimum efficient scale of firms
