1/15
  • Productive Efficiency
    Achieved when production occurs at the lowest possible cost, specifically at the minimum point of the average total cost curve.
  • Allocative Efficiency
    Occurs when the quantity produced matches consumer preferences, where marginal benefit equals marginal cost.
  • Average Total Cost
    Represents the total cost per unit of output, combining both fixed and variable costs, crucial for efficiency analysis.
  • Excess Capacity
    Describes a situation where firms produce less than the output level that minimizes average total cost, indicating inefficiency.
  • Marginal Revenue
    The additional income from selling one more unit, guiding firms' profit-maximizing output decisions.
  • Marginal Cost
    The extra cost incurred from producing one additional unit, essential for determining optimal production.
  • Demand Curve
    Graphically represents consumers' willingness to pay for different quantities, reflecting marginal benefit.
  • Profit Maximizing Quantity
    The output level where marginal revenue equals marginal cost, chosen by firms to maximize profit.
  • Zero Profit Point
    The situation where price equals average total cost, resulting in no economic profit for firms in the long run.
  • Economies of Scale
    Cost advantages realized as output increases, leading to lower average total costs at higher production levels.
  • Perfect Competition
    A market structure where firms are price takers, achieving both productive and allocative efficiency in the long run.
  • Imperfect Competition
    Market structures, such as monopolistic competition, where firms have some price-setting power and inefficiencies persist.
  • Socially Optimal Quantity
    The output level where consumers' marginal benefit equals producers' marginal cost, maximizing total welfare.
  • Average Revenue
    The revenue earned per unit sold, often equal to price in competitive markets.
  • Downward Sloping Demand
    A characteristic of monopolistic competition, indicating that firms face a negatively sloped demand curve for their product.
