Assume the marginal revenue product ( MRP ) for minority workers is given by
MRP = 40 − 5N m , where N m is the number of minority workers. The market wage for minorities is $5/hr. Discriminating firms devalue the contributions of minorities at a rate of $5/hr (i.e., d = 5).
(a) How many minority workers do non-discriminating firms hire? What is their profit level?
(b) How many minority workers do discriminating firms hire? What is their profit level?
