Information about Economy Of Scale

The increase in output from Q to Q2 causes a decrease in the average cost of each unit from C to C1.
Economies of scale characterizes a production process in which an increase in the scale of the firm causes a decrease in the long run average cost of each unit.

Economies of scale can be enjoyed by any size firm expanding its scale of operation. The common ones are purchasing (bulk buying of materials through long-term contracts), managerial (increasing the specialization of managers), financial (obtaining lower-interest charges when borrowing from banks and having access to a greater range of financial instruments), marketing (spreading the cost of advertising over a greater range of output in media markets). Each of these factors reduces the long run average costs (LRAC) of production by shifting the short-run average total cost (SRATC) curve down and to the right.

This should not be confused with increasing returns to scale which is represented by the SRATC where simply increasing output within current capacity reduces the short run cost per unit.

This is, of course, an extremely simplistic example and, in real life, there are countering forces of diseconomies of scale. As these forces balance, an optimum production volume can be found (referred to as constant returns to scale).

This principle can be equally applied to an organization resulting in firms within a particular industry tending to be similar sizes. Economists have studied this effect as the theory of the firm.

A natural monopoly is often defined as a firm which enjoys economies of scale for all reasonable firm sizes; because it is always more efficient for one firm to expand than for new firms to be established, the natural monopoly has no competition. However, standard economic theory also holds that on account of the unique shapes of the natural monopoly's LRAC and SRAC, it can never experience economic profit and thus requires subsidies or other government intervention to remain profitable.

In the short run at least one factor of production is fixed. Therefore the SRAC curve will fall and then rise as diminishing returns sets in. In the long run however all factors of production vary and therefore the LRAC curve will fall and then rise according to economies and diseconomies of scale.

There are two typical ways you can have Economies of Scale: 1. High fixed cost and constant marginal cost 2. Low or no fixed cost and, declining marginal cost

In economic models, the long-run time frame assumes no fixed factors of production. Firms can enter or leave the marketplace, and the cost (and availability) of land, labor, raw materials, and capital goods can be assumed to vary.

In economics, average cost is equal to total cost divided by the number of goods produced (Quantity-Q). It is also equal to the sum of average variable costs (total variable costs divided by Q) plus average fixed costs (total fixed costs divided by Q).

The long run average cost (LRAC or LAC) curve illustrates - for a given quantity of production - the average cost per unit which a faces in the long run (i.e. when no factors of production are fixed).

LRAC curve is derived from a series of short run average cost curves.
