III. If a competitive industry is in long-run equilibrium, a decrease in demand causes firms to earn negative profit because the market price will fall below average total cost.

Explanation:

A perfect competition is characterised by many buyers who sell homogenous products.

All firms in a perfect competition earn zero economic profit in the long run because there are no barriers to entry or exit.

In the long run, equilibrium occurs at: P = LMC = LATC

If demand falls, prices would fall below average total cost and the firm would earn negative profit .
