Explanation / Answer

Answer

1)

The correct answer is (b) has market power.

Monopoly is the extreme case of market power(complete market power). Market power is defined as the ability of a firm to charge price above Marginal cost. More the ability to charge higher price more will be market power. Hence, even if a firm does not have a monopoly but has high market power then he can still charge higher price and hence can influence Market price.

Hence, The correct answer is (b) has market power

2) The correct answer is (c) The market price is lower than its average variable cost(AVC)

A firm has incurred a fixed cost and it cannot do anything with it in a short run. Hence what he has to do is now compare Price with Variable cost because if his price is lesser than Average variable cost then his revenue is not enough to cover Total Variable cost hence it is preferable for him to shut down and by doing that he only looses Fixed cost rather than Fixed cost + (TVC - TR).

Hence, the correct answer is (c) The market price is lower than its average variable cost(AVC)
