Answer:
a higher; the same
Explanation:
Solow's law attempts to explain how long term productivity is affected by capital accumulation and population growth.
As population increases the steady state of capital per person decreases.
However when the rate of savings is high in the economy there will be a larger capital stock and higher output in the long run.
If the economies are identical as is stated above the the rate of growth of output per worker will be the same.
