You learned in this chapter that a profit maximizing firm will hire labor (or any other input) until MRP = wage.Why might a firm that refuses to hire African American, or gay, or female (or any minority group) employees face higher production costs than a non-discriminating firm?What would be the fate of a discriminating firm under perfect competition?Can you think of any circumstances under which a firm might gain by discriminating against a particular group of employees or customers, because of the tastes of its other customers. (Give an example).
