Samuelson-Modigliani developed the dual theorem by applying the neoclassical growth model. We should now ask whether the dual theorem is intrinsic to the macro growth theory or it depends on the neoclassical growth model. This paper examines the dual theorem rather in the Keynesian world. Our model assumes an independent Robinsonian investment function and the KeynesWicksell adjustment process. Our main result is: if the adjustment speed of the product price is faster than that of money wage rates, then the dual theorem does not hold for any magnitude of saving propensity, while it is true otherwise.
