Do you agree with the classical (supply-side) theory of aggregate demand and real GDP or the Keyensian (demand-side) theory of aggregate demand and real GDP? Explain why you agree more with either the classical or Keyensian theory and do not take the easy road by saying you agree with both. Get on one side or the other and make sure to cite at least one source.
