Homework Answers

Answer #1

33. c.Both a and b. Diseconomies of scale occur in the long run when production is very large and mismanagement leads to increase in average cost with the increase in output. Thus, it is advisable to decrease production.

34. d.None of the above. The perfectly competitive industry is one where there are a large number of firms who sell a homogenous product at the given price and there are no entry-exit barriers.

36. d.None of the above. In long run, competitive industry earns zero normal profit and produce at the minimum average cost where there is efficiency.

37. a.Perfectly elastic demand for its output. The demand curve for the comptitive firm is horizontally fixed at the market price.

39. d.it accepts the market price as given

40. d.Marginal cost equal price, as long P > AVC
