See a monopolist which cannot price discriminate but that maximizes profit. When this firm produces the level of output where is average cost at its minimum that will charge a price: (i) equal to marginal cost and generate zero economic profit. (ii) equal to marginal cost and generate a positive economic profit. (iii) above marginal cost and minimize the losses this cannot avoid. (iv) above marginal cost and produce a positive economic profit.
Can anybody suggest me the proper explanation for given problem regarding Economics generally?
