What most easily explains the shape of the value-of-marginal-product curve

Question

Quizplus · Accepted Answer

The value-of-marginal-product curve is shaped by the law of diminishing marginal returns, which states that as more units of a variable input (such as labor) are added to a fixed input (such as capital), the marginal product of the variable input eventually declines. Therefore, the shape of the value-of-marginal-product curve is downward-sloping due to diminishing marginal product.
