The Law Of Diminishing
Returns
In the combination of input
factors when one particular factor is increased continuously without changing
other factors the output will increase in a diminishing manner. Let us assume
that a person preparing for an examination continuously prepares without any
break. The output or the understanding and the coverage of the syllabus will be
more in the beginning rather than in the later stages. There is a limit to the
extent to which one factor of production can be substituted for another. The
total production increases up to an extent and it gets saturated or there won’t
be any change in the output due to the addition of the input factor and further
it leads to negative impact on the output. That means the marginal production
declines up to an extent and it reaches zero and becomes negative. The point at
which the MP becomes zero is the maximum output of the firm with the given set
of input factors. This law is applicable in all human activities and business
activities.
For example with two sewing
machines and two tailors, a firm can produce a maximum of 14 pairs of curtains
per day. The machines are used only from 9 AM to 5 PM and the machines lie idle
from 5 pm onwards. Therefore the firm appoints 2 more tailors for the second
shift and the production goes up to 28 units. Then adding two more labour to
assist these people will increase the output to 30 units. When the firm
appoints two more people, then there won’t be any change in their production
because their Marginal productivity is zero. There is no addition in the total
production. That means there is no use of appointing two more tailors. Therefore, there is a limit for output
from a fixed input factors but in the long run purchase of one more sewing
machine alone will help the firm to increase the production more than 30 units.
