The problem asks us to calculate the output level ($Q$) using a given production function and specific amounts of capital ($K$) and labour ($L$).
The production function is given by:
$ Q = 2 \cdot K^{1/3} \cdot L^{2/3} $
We are provided with the following input values:
Substitute the given values of $K$ and $L$ into the production function:
$ Q = 2 \cdot (8)^{1/3} \cdot (27)^{2/3} $
Now, let's calculate the terms involving exponents:
Substitute these calculated values back into the equation for $Q$:
$ Q = 2 \cdot 2 \cdot 9 $
Performing the final multiplication:
$ Q = 4 \cdot 9 $
$ Q = 36 $
Therefore, the output level is 36 units when 8 units of capital and 27 units of labour are used.
| (i) Stage-I | (a) Total product declines, Marginal product is negative |
| (ii) Stage-II | (b) Total product increases at an increasing rate, marginal product positive |
| (iii) Stage-III | (c) Total product increases at a diminishing rate, marginal product is zero. |
