Explanation / Answer

38. e) both (c) and (d)

Shaded area shows total cost and total revenue of firm in the long run.

39. c) it can sell a given quantity of output at any price.

Monopolistic competition refers to a market situation in which there are large number of buyers and sellers. The sellers sell closely related or differentiated products but not identical product. The products are close substitutes of each other. Product differentiation is the most important feature of monopolistic competition. Each firm under monopolistic competition enjoys the monopoly over the brand of the commodity and thus the firm has the control over the price of the commodity. Under monopolistic competition, MR < AR and AR and MR curve slope downwards and MR curve lies below AR curve. But these curves are more elastic. Example: Firms producing different brands of shampoos like Sunsilk, Pantene, Head & Shoulders, Dove etc. Monopolistic competition combines the features of monopoly and perfect competition.

40. b) natural monopoly
