  • Who determines the price in a perfectly competitive market?
    The market determines the price, and individual buyers and sellers are price takers.
  • What does it mean for firms to be 'price takers' in perfect competition?
    Firms must accept the market price and cannot influence it by their own actions.
  • How many buyers and sellers are typically present in a perfectly competitive market?
    There are many buyers and many sellers, often considered almost infinite.
  • What is the significance of free entry and exit in perfect competition?
    Firms can freely enter or leave the market without significant barriers.
  • Give an example of a perfectly competitive market.
    Agricultural products like wheat or foreign exchange markets are examples.
  • What does the demand curve look like for an individual firm in perfect competition?
    It is perfectly elastic, represented by a horizontal line at the market price.
  • Why is the individual firm's demand curve horizontal in perfect competition?
    Because the firm can sell any quantity at the market price but cannot sell at a higher price.
  • What happens if a firm in perfect competition tries to charge a price above the market price?
    It will sell nothing, as buyers will purchase from other sellers at the market price.
  • What is the equilibrium price (P*) in a perfectly competitive market?
    It is the price where market demand equals market supply.

    The market demand curve slopes downward, while the individual firm's demand curve is horizontal.
  • Why can't a single firm influence the market price in perfect competition?
    Because each firm is a small part of the market and their output is insignificant relative to total market supply.
  • What role does identical goods play in perfect competition?
    Identical goods ensure that buyers have no preference for one seller over another, reinforcing price taking.
  • How does perfect competition affect a firm's production and profit decisions?
    Firms base their decisions on the market price, as they cannot influence it and must accept it.
  • What market structures do not have a perfectly elastic (horizontal) demand curve for individual firms?
    Monopolistic competition, oligopoly, and monopoly do not have a horizontal demand curve for individual firms.
