Answer:
Economies of scale; positive economic profits.
Step-by-step explanation:
Economies of scale directly or imply increase or massive production by a company or group of firm. And in most cases this is not seen to be collective as it is unique and implies to a particular firm in their cause of business. This make shift can be caused or triggered by a lot of factors; example can be seen when things are been done manually with man power and at the long run a machine is been put to place, causing massive production.
Positive economic profit on the other hand is simply seen to be the effect of the economies of scale as it causes growth in the company, sometimes pushing to opening of many other branches of the same company. It is also seen to benefit the buyers as unit per capital of the said goods will have to reduce in cost too.
