Q. 9. Explain the theory of determination of Income and employment with the help of aggregate demand and aggregate supply curves.


Why must aggregate demand be equal to aggregate supply at the equilibrium level of income and output? Explain with the help of a diagram.

Q. 10. Explain with the help of a diagram how equilibrium level of income in an economy is determined by saving and investment curves? Will there always be full employment at equilibrium level of income?
