For a monopoly firm, price exceeds marginal cost.
P > MR = MC profit-maximizing firms
A monopolist’s marginal revenue is always less than the price of
its good.
The intersection of the marginal-revenue curve and the
marginal-cost curve determines the profit-maximizing quantity.
And then the demand curve shows the price consistent with this
quantity.
The Monopolist’s will receive economic profits as long as price
is greater than average total cost.
