Explanation:
According to the marginal productivity theory , the firm will hire the number of labor where marginal revenue product of labor equals wage rate ( MRPL = W ) or marginal revenue product of labor is greater than the wage rate ( MRPL > W ).
Marginal physical product of labor = Change in Quantity / Change in number of labor
or
MPP = ∆ Q / ∆ L
Marginal revenue product of labor = Marginal physical product of labor * Price
or
MRPL = MPP * Price
