1/15
  • Perfect Competition
    A market with countless firms where no single producer can affect the prevailing price, ensuring uniformity in product pricing.
  • Market Price
    The prevailing value at which goods are exchanged, determined by overall supply and demand, not by individual sellers.
  • Barriers to Entry
    Obstacles preventing new firms from joining a market, absent in this structure, allowing unrestricted participation.
  • Profit Maximization
    Achieved when additional revenue from selling one more unit equals the extra cost incurred, guiding optimal output.
  • Marginal Revenue
    The extra income received from selling one additional unit, identical to price in this market structure.
  • Marginal Cost
    The added expense from producing one more unit, crucial for determining optimal production levels.
  • Average Revenue
    Total income divided by quantity sold, matching price in this market, forming a horizontal line on graphs.
  • Economic Profit
    Earnings after accounting for all explicit and implicit costs, including opportunity costs, which vanish in the long run.
  • Average Total Cost
    Overall production expenses per unit, with market price stabilizing at its lowest point in the long run.
  • Productive Efficiency
    Occurs when goods are produced at the lowest possible cost, achieved when price equals minimum average total cost.
  • Allocative Efficiency
    Realized when resources are distributed to maximize societal benefit, indicated by price equaling marginal cost.
  • Long Run
    A period where firms can freely enter or exit, leading to zero economic profit and price equaling minimum average total cost.
  • Short Run Shutdown
    A temporary halt in production when revenue fails to cover variable costs, distinct from permanent market exit.
  • Foreign Exchange Market
    A setting where currencies are traded, exemplifying this market structure due to standardized products and price-taking behavior.
  • Wheat Market
    An agricultural sector illustrating this model, with numerous producers and indistinguishable products.
