The marginal revenue product of labor curve is the firm’s
labor demand curve
The demand curve facing a monopoly
is equal to the industry demand curve
For a monopolist
MR < P, MR < average revenue, MR declines as output increases

the increasing opportunity cost of labor and the decreasing marginal utility of income as a person works more hours.
Derived demand means that
