If investment exceeds saving, income level rises, saving increases and becomes equal to investment. Note that for the classical equilibrium real wage, the Keynesian supply exceeds the demand. Whereas government expenditure has a direct effect on investment, output and employment, money affects these variables only indirectly and unpredictably. Thus, real variables, like employment, output etc., are not affected. In the Keynesian models, we do not assume that the real wage will be equal to the equilibrium real wage.
