Aproach:
- the revenue value of the output from the last unit of input employed equals the cost of employing that input unit
This method compares the estimated
cost of each unit of input to that
input’s contribution with
projected total revenue.
If the increase in projected total revenue coming from the input unit exceeds its cost, it contributes to total profit.
If the increase in projected total revenue does not cover the input unit’s cost, total profit is diminished.
Profit maximization based on the employment of inputs occurs where
the next input unit for each type of resource used no longer makes any contribution to total profit.
