Define Marginal product of a factor?

Answer»

It is the addition or the increment made to the total product when one more unit of the variable input is employed . In other words, it is the ratio of the change in the total product to the change in the units of the input. It is expressed as

Where, MP = ∆TP/∆N

Where, MP = Marginal Product

∆TP = Change in total product

∆N = Change in units of input

It is also expressed as

MP = TP[n] – TP [n – 1]

MP = Marginal product

TP [n] = Total product of employing nth unit of a factor.

TP [n – 1] = Total product of employing the previous unit of a factor, that is, [n – 1]th unit of a factor.
