Quizplus · Accepted Answer

The movement from A to B to C in Figure 7.4 illustrates diminishing returns to capital. This means that as more capital is added per hour worked, the increase in real GDP per hour worked slows down and eventually reaches a point where adding additional capital per hour worked actually decreases real GDP per hour worked.
