The following table provides information about labor supply and the marginal revenue product of labor for a prot-maximizing monopsonist. Marginal Revenue Product of Labor 36 33 3O 27 24 21 18 15 12 Wage Labor Supply Suppose a monopsony rm in this market has employed 21 workers at a wage of $7. What will be the change in prots if the rm hires the 22nd worker? You can nd the change in prot by identifying the additional revenue generated when the rm hires the 22nd worker (M RPL), and subtracting the marginal cost of hiring the 22nd worker. Keep in mind, when the rm hires less than the prot-maximizing level of employment, additional hiring will result in MB>MC and a positive addition to prot. When the rm hires more than the prot-maximizing level of employment, the marginal cost of hiring exceeds the marginal benet and the rm loses prot
