Answer: Economies of scale pertain to the long run only.
Explanation:
Economies of Scale is a long run phenomenon and is defined as the cost advantage that a firm experiences as a result of an increase in its output. The benefit arises as a result of the inverse relationship between quantity produced and per-unit fixed cost. The higher the quantity of output that are produced, the lower the per-unit fixed cost.
Economies of scale leads a fall in the average variable costs with an increase in the level of output. This is as a result of synergies and operational efficiencies which comes into place due to the increase in the scale of production. Economies of scale is a vital concept as it shows the competitive advantages big firms have over the small firms.
