Economies of scale is related to and can easily be confused with the theoretical economic notion of returns to scale. Where economies of scale refer to a firm's costs, returns to scale describe the relationship between inputs and outputs in a long-run (all inputs variable) production function.
Economies of scale refers to the cost advantage arise from increasing amount of production. Mathematically, it is a situation in which the firm can double its output for less than doubling the cost, which brings cost advantages. Usually, economies of scale can be represented in connection with a cost-production elasticity, Ec. [3]
Research and development (R&D) is a typical example of economies of scope. In R&D economies, unit cost decreases because of the spreading R&D expenses. For example, R&D labs require a minimum number of scientists and researchers whose labour is indivisible. Therefore, when the output of the lab increases, R&D costs per unit may decrease. The ...
For larger households, each additional adult is given a smaller value of 0.5 to reflect the economies of scale achieved when people live together, arising when households share resources such as water and electricity, which reduces living costs per person. Children under the age of 14 are given a value of 0.3 to take account of their lower ...
For example, if there are increasing returns to scale in some range of output levels, but the firm is so big in one or more input markets that increasing its purchases of an input drives up the input's per-unit cost, then the firm could have diseconomies of scale in that range of output levels.
If only diseconomies of scale existed, then the long-run average cost-minimizing firm size would be one worker, producing the minimal possible level of output. However, economies of scale also apply, which state that large firms can have lower per-unit costs due to buying at bulk discounts (components, insurance, real estate, advertising, etc.) and can also limit competition by buying out ...
