In the neoclassical growth model we express the investment function as i= sf(k), where i is investment per worker, s is the saving ratio, k is capital per worker, and y is output per worker.
A) Plot the saving function, i= sf(K) and output function y=f(k)=k1/2, where s=0.3and values of k vary between 4 and 9
B) Find consumption per worker for k=4 and k=9
