A monopolist produces an economically inefficient level of output since: (i) the difference among marginal revenue [MR] and marginal costs [marginal costs [MC] is maximized. (ii) P > average total costs [ATC], therefore MSB < MSC. (iii) all consumer surplus is expropriated. (iv) P > marginal costs [MC], so MSB > MSC. (v) too much is charged for too much production.
How can I solve my Economics problem? Please suggest me the correct answer.
