    Study Notes

    Decision Time Frames

    • The short run is a timeframe where at least one factor of production is fixed.
    • The long run is a timeframe where all factors of production can be varied.
    • Plant refers to factors of production that are fixed in the short run.
    • The short run is typically one year or less, where some factors are fixed and others are variable.
    • The long run is the time period needed to adjust all inputs and outputs.

    Short-Run Technology Constraint

    • Total product curve illustrates the maximum output for varying amounts of labor.
    • Points above the curve are unattainable (or inefficient)
    • Points below the curve are attainable but inefficient
    • Points on the curve are attainable and efficient
    • Marginal product reaches a maximum when the rate of increase in output diminishes with each added worker
    • The total product curve shows the maximum output attainable for different levels of inputs (workers)

    Short-Run Cost

    • Total cost (TC) is the sum of total fixed cost (TFC) and total variable cost (TVC).
    • Average fixed cost (AFC) is TFC divided by output.
    • Average variable cost (AVC) is TVC divided by output.
    • Average total cost (ATC) is TC divided by output (or AFC + AVC).
    • Marginal cost (MC) is the change in total cost from producing one more unit of output.
    • The marginal cost curve is typically U-shaped, as increasing or decreasing returns to scale begin to occur.

    Long-Run Cost

    • The long-run average cost (LRAC) curve shows the lowest cost at which a given level of output can be produced.
    • Economies of scale occur when the LRAC curve slopes downward.
    • Diseconomies of scale occur when the LRAC curve slopes upward.
    • Constant returns to scale occur when the LRAC curve is horizontal.
    • The minimum efficient scale is the output at which the LRAC curve reaches its minimum point.
