Using the same simple macro model we developed in Module 2:

a.  Show what will happen to national income (GDP) if the administration implements another $100 (billion) stimulus spending package.

b. Show what would happen if instead of a government spending package, the administration implemented a $100 tax cut.

c.  From your results, find the numerical values of the derivatives dY/dG  and dY/dT.   (Hint: Numerically, dY  is just the new value of  Y  less the old value and dG  is the new value of government spending less the old one.  Find the ratios of those numbers and you have found the value of the derivative.) Which policy has the largest effect and why?
