Final answer:
In the Solow model, the steady-state capital per worker k can be found by setting the saving rate s equal to the depreciation rate d plus the growth rate of the labor force n and solving for k. Given the specific values provided, the steady-state capital per worker k is 1.
Step-by-step explanation:
In the Solow model, the steady-state capital per worker k can be found by setting the saving rate s equal to the depreciation rate d plus the growth rate of the labor force n and solving for k.
Given that y = 2√k, we can rewrite the equation for the steady-state capital per worker as:
s * y = (n + d) * k
Substituting the given values, we have:
0.25 * (2√k) = (0.1 + 0.4) * k
Simplifying this equation, we get:
0.5√k = 0.5k
Dividing both sides of the equation by 0.5k, we obtain:
√k = k
Squaring both sides of the equation, we find:
k = k * k
Dividing both sides of the equation by k, we get:
1 = k
Therefore, the value of the steady-state capital per worker k is 1.
