Economies of Scale and Diseconomies of Scale (Eng Rec.)

The occurrence of increasing returns is explained in terms of the economies of scale. Economies of scale refer to the situation in which increasing the scale of production reduces the unit cost of production or raises output per unit of the factor inputs.

Returns to scale are technical, while economies of scale include the technical as well as monetary economies."


Broadly, economies of scale are classified as:

(i) Internal Economies of Scale: These arise due to the change in the size of the firm and are available to that firm only.
(ii) External Economies of Scale: These arise due to the expansion of the industry, i.e. the number of firms.

These are those economies that are firm-specific. These are available to that particular firm in the industry that seeks to increase its level of output by way of increasing its scale of production. These are called internal because these are not shared by other firms in the industry which are not expanding their scale of production.
