Economies of Scale:
‘Economies’ means benefits. The scale refers to the size of unit. ‘Economies of Scale’ refers to the cost benefits due to the bigger size of production. Since the volume of production rises, the overhead cost will come down. The bulk buy of inputs will provide a better bargaining power to the producer that will decrease the average variable cost too. All such benefits are due to the large scale production and such advantages are termed as economies of scale.
There are two kinds of economies of scale:
a) Internal economies of scale;
b) External economies of scale
