Answer #1

In the Solow Growth model, what is the level of investment per capita that ensures that capital-labor ratio stays unchanged ___dkt_____

Capital-labor ratio stays unchanged if investment equals depreciation.
Change in capital stock = investment - depreciation = 0
So, investment = depreciation

Depreciation is given by dkt where d is the rate of depreciation and kt is the capital labor ratio.
So, capital-labor ratio stays unchanged if investment per capital equals dkt.

Suppose, in the Solow growth model, that learning by doing is captured as a cost of installing new capital. In particular, suppose that for each unit of investment, r units of goods are used up as a cost to firms. (a) Determine how r affects the steady state quantity of capita per worker, and per capita income. (b) Now suppose that r differs across countries. How will these countries differ in the long run? Discuss.
