Answer:
66.67%
Step-by-step explanation:
We are told that the initial capital per worker is $30,000. Also, that the capital per worker eventually rises to $60,000. From both, we can calculate the change in capital per worker to be
(60,000 – 30,000). = $30,000
The change in output per worker is given to be $45,000. This then means that it's productivity growth attributed to growth in total factor productivity is will be follows:
Growth Rate = (Change in Input) / (Change in Output) x 100%
Growth Rate = 30,000 / 45,000 x 100
Growth Rate = 66.67%
