Economies of scale refers to when:

Multiple Choice an increase in the quantity of output increases average total cost in the long run. None are correct. average

In the long run when average total cost does not depend on the quantity of output, this is called:

Multiple Choice O minimum average total cost. o economies of scale. constant economies to scale. diseconomies of scale.

Commodities:

Multiple Choice are identical regardless of who produced them. All are correct. have no product differentiation. are a specia

We assume that in the long run in a perfectly competitive market:

Answer #1

Answer : 1) The answer is option D.

When quantity increase, if long-run average total cost decrease then the situation is called increasing returns to scale. Increasing returns to scale is also known as economies of scale. Therefore, option D is correct.

2) The answer is option C.

If quantity does not depend on long-run average total cost then the situation is called constant returns to scale. Constant returns to scale is also known as constant economies of scale. Therefore, option C is correct.

3) The answer is option B.

Commodities are a special standardized goods and homogeneous. No matter who are producing commodities. As options A, C and D are correct hence the answer is option B.

4) The answer is option B.

In perfectly competitive market in long-run many firms enter or exit from the market. This is an assumption of perfectly competitive market. Therefore, option B is correct.
