Answer:
c. production possibilities curve shifted outward
Explanation:
As we know that
Labor productivity = total output ÷ worker per hours
Percentage change in total output is
= Percentage change in labor productivity + Percentage change in worker - hours
So
The change in total output is
= 4 + 4
= 8
In whole the real GDP would be rise by 8%
It can be seen that the labor productivity and the workers would be grow this represent the production possibility curve would be shiftward to the outside direction in the case when more of the both goods would be produced or generated
