  • Marginal Cost
    Change in total cost from producing one more unit, acting as the main driver for shifts in average cost.
  • Average Cost
    Total cost divided by output quantity, reflecting the per-unit expense of production.
  • Average Fixed Cost
    Portion of cost that remains constant and is spread over increasing output, always declining as output rises.
  • Average Variable Cost
    Per-unit expense from variable inputs, typically forming a U-shape as output increases.
  • Average Total Cost
    Sum of per-unit fixed and variable expenses, showing a U-shaped pattern as output changes.
  • Fixed Cost
    Expense that does not change with output, such as equipment or rent, impacting only the average fixed cost.
  • Variable Cost
    Expense that rises with increased production, influencing both average variable and total costs.
  • Production Efficiency
    Optimal use of resources to minimize per-unit expenses, highlighted by cost curve behaviors.
  • Cost Management
    Strategic control of expenses to optimize output and profitability, informed by cost relationships.
  • Diminishing Marginal Productivity
    Phenomenon where adding more input eventually yields smaller increases in output, affecting cost curves.
  • U-Shape
    Characteristic pattern of average variable and total cost curves, falling then rising with output.
  • Aggregate Supply
    Total output available in an economy, influenced by underlying cost structures and productivity.
  • Quantity
    Number of units produced, serving as the denominator in average cost calculations.
  • Total Cost
    Sum of all expenses, both fixed and variable, incurred in producing a given output.
