Answer:
C) The equilibrium wage decreased.
Explanation:
Marginal product is the change in total production as a result of a one-unit-addition of a factor of production. The equilibrium wage will decrease as the increase in marginal product of the computer programmers causes a subsequent increase in the demand for computer programmers, since employing one more worker brings about an even higher production. The resources available for wages are held constant and have to be shared among the now bigger number of programmers, lowering the wage equilibrium level.
