Long-Run Average Cost Curves

A graphical representation showing the average cost per unit of output over a long period, where all inputs, including capital, are variable.

Economies of Scale

Cost advantages that enterprises obtain due to their scale of operation, leading to a reduction in average costs per unit as output increases.

Diseconomies of Scale

The situation in which a business grows so large that the costs per unit increase, as opposed to economies of scale where costs per unit decrease with the increase in output.

Long-Run Average Cost Curve

A graphical representation that shows the minimum average cost at which any output level can be produced after all inputs are adjustable. It reflects economies and diseconomies of scale.
