When a firm does not influence the wage rate no matter how many workers this hires, then: (1) MRPL = MRCL for all feasible output levels for the firm. (2) MRCL = MPPL for all feasible output levels for the firm. (3) MPPL = MRPL for all feasible output levels for the firm. (4) MR = MC for all feasible output levels for the firm. (5) w = MRCL for all feasible output levels for the firm.
Please choose the right answer from above...I want your suggestion for the same.
