    Study Notes

    Costs

    • Explicit costs: Monetary outlays that a firm makes.
    • Implicit costs: Non-monetary outlays that a firm incurs, such as the opportunity cost of using its own resources.

    Short-Run vs. Long-Run

    • Short-run: Period where at least one input is fixed. Output can be varied by changing the intensity of use of the fixed input.
    • Long-run: Period where all inputs are variable. Firms can adjust the size of their plants and the amount of capital.

    Costs & Production

    • Total fixed costs (TFC): Costs that remain constant regardless of production level.
    • Average fixed cost (AFC): TFC divided by the quantity of output.
    • Total variable costs (TVC): Costs that change with the level of output.
    • Average variable cost (AVC): TVC divided by the quantity of output.
    • Total cost (TC): TFC + TVC.
    • Average total cost (ATC): TC divided by the quantity of output.
    • Marginal cost (MC): The change in total cost divided by the change in output.

    Economies & Diseconomies of Scale

    • Economies of scale: Output increases at a faster rate than input, causing average cost to decrease.
    • Diseconomies of scale: Output increases at a slower rate than input, causing average cost to increase.
    • Constant returns to scale: Output increases proportionally to input, causing average cost to remain constant.
