Answer:

b) so do average wages

Explanation:

  • In perfect competition's equilibrium, productive factors are paid according to  their marginal productivity. This means that productive factors' payments will be directly explained by their productivity.
  • This comes from the fact that a firm maximizes profits, subject to its budget constraint, in an optimal way. Equilibrium solution will result in the following condition: [tex]\frac{MP_L}{MP_K} =\frac{P_L}{P_K}=\frac{Wages}{P_K}[/tex], where [tex]MP_L[/tex] is the marginal productivity of labour and [tex]PM_K[/tex] is the marginal product of capital,[tex]P_L[/tex] is the price of labour (or wages) and [tex]P_K[/tex] is the price of capital.
  • Then, because the price of labour is proportional to its productivity, if labour productivity rises, the price of labour will increase.
