For the average total cost curve of a firm without economies of scale, what happens to costs as output increases?

a. costs initially go down and then go up.

b. costs go down.

c. costs go up.

d. costs initially go up and then go down.

a.Costs initially go down and then go up.

Explanation:

The average total cost curve of an enterprise consists of the sum of the fixed cost curve and the variable cost curve. Fixed costs are those that cannot be eliminated in the short term, such as the utility bill. Varied costs are those that can be reduced if the company decreases the quantity produced. For example, inputs and labor.

Thus, initially the total cost curve tends to decrease as production increases, as fixed costs are slowly diluted as the production process advances. However, at some point this cost curve tends to increase, because if there is no economy of scale, marginal production will be decreasing, ie, after a certain point of production, each additional production will be more expensive (will require more variable costs ) and this will lead to an inflection in the average cost curve, which will increase further.

there are conflicting perceptions. what cannot be denied is that despite a long history of discrimination, they finally chose to bow out in grace and handed over power to the majority. it was a painful experience for them to part with their prerogatives and some chose to leave the country. however, they did decide to bite the bullet and go through the process with minimum obstructions.

presently, whites are still a force to reckon with. they are well educated, have technical and business expertise, they understand imperatives of good governance and are responsible for keeping south africa connected with developed countries. despite a bitter history, they are useful team members of the south african team.
