In equilibrium these prices must equal the respective marginal costs MC < sub > 1 </ sub > and MC < sub > 2 </ sub >; remember that marginal cost equals factor ' price ' divided by factor marginal productivity ( because increasing the production of good by one very small unit through an increase of the employment of factor j requires increasing the factor employment by 1 / MP < sub > ji </ sub > and thus increasing the cost by w < sub > j </ sub >/ MP < sub > ji </ sub >, and through the condition of cost minimization that marginal products must be proportional to factor ' prices ' it can be shown that the cost increase is the same if the output increase is obtained by optimally varying all factors ).
