Consider two countries, Twilightia and Avataria, which can be described by the Solow model. Avataria has a capital-labor ratio that is initially twice as big as that of Twilighta, but neither country is yet in a steady state. Both countries have the same production function,
Y(K,L)=4(K)^{1/2}(L)^{1/2}
What are the output growth rates of these countries in the long run when Avataria has a 20% investment rate and 16% depreciation rate, while Twilightia has a 15% investment rate and 12% depreciation rate.
