    Agricultural products like wheat and foreign exchange markets are examples of perfect competition.
  • What are barriers to entry, and do they exist in perfect competition?
    Barriers to entry are obstacles that prevent new firms from entering a market, and in perfect competition, there are none.
  • How do firms in perfect competition maximize their profit?
    Firms maximize profit where marginal revenue equals marginal cost.
  • What happens to economic profit for firms in perfect competition in the long run?
    In the long run, firms in perfect competition cannot make economic profits; price stabilizes at the minimum of average total cost.

    In perfect competition, price always equals average revenue.
  • How does price relate to marginal revenue in perfect competition?
    Price equals marginal revenue in perfect competition, which is unique among market structures.

    Price equals marginal cost in perfect competition, leading to productive and allocative efficiency.
  • Why can't firms in perfect competition influence the market price?
    Because each firm's output is a tiny fraction of the total market supply, so individual actions do not affect the overall price.
  • What does it mean for a market to have no barriers to entry or exit?
    It means firms can freely enter or leave the market without facing obstacles.

    They choose the output where marginal revenue equals marginal cost.

    It ensures both productive and allocative efficiency in the market.
  • How does economic profit differ from accounting profit in perfect competition?
    Economic profit includes opportunity costs, while accounting profit only considers explicit monetary costs.
