The quantity of A demanded per firm is of about 4.183 and is of about 418.282. We can see that the quantity of land demanded went down.
\(\frac{\partial Q}{\partial A} = \frac{20}{3} M^{\frac{1}{3}}A^{-\frac{1}{3}}\)
\(\frac{\partial Q}{\partial A} = \frac{20}{3} 9^{\frac{1}{3}}[(\frac{3}{5})^{\frac{3}{2}}*9]^{-\frac{1}{3}}=\frac{20}{3}*(\frac{5}{3})^{0.5} \approx 8.607\)
Total income per firm going to A is equal to \(\frac{\partial Q}{\partial A}*A = [\frac{20}{3}*(\frac{5}{3})^{0.5}]*[(\frac{3}{5})^{\frac{3}{2}}*9] =36\). Total income going to A is equal to 3600.
\(\frac{\partial Q}{\partial M}= 2\) So The total income going to labor is equal to 1800.
Total quantity will now be equal to \(Q=10M^{\frac{1}{3}}A^{\frac{2}{3}}\) \(\Longrightarrow\) \(Q=10*900^{\frac{1}{3}}*[100*(\frac{3}{5})^{\frac{3}{2}}*9]^{\frac{2}{3}} =5400\)
Hence the absolute share of income going to labor is the same as before (1/3) and the two remaining thirds go to land.
