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.
