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.
