How much national income or GNP increases as a result of any autonomous expenditure such as government expenditure, investment expenditure, net exports is determined by a shift in aggregate demand curve by the size of simple Keynesian multiplier when price level is fixed. We, therefore, see that the size of multiplier instead of being equal to 4, as it would have been in the case of a closed economy, is equal to 2 in the open economy with — as the marginal propensity to import. With marginal propensity to save MPS being equal to 0. The rise in real GDP is more than double the rise in the aggregate expenditure function. With short-run aggregate supply curve sloping upward, a rightward shift in aggregate demand curve raises new equilibrium GNP level not equal to the horizontal shift in the aggregate demand curve but less than it. In view of this when increase in investment leads to the rise in money incomes of the people, a large part is spent on food grains. For example, if investment equal to Rs. Thus, the deficiency in private investment which leads to the state of depression and underemployment equilibrium will now be made up and a state of full employment will be restored.
Keynes' Theory of Investment Multiplier (With Diagram)
An initial change in aggregate demand can have a much greater final impact on the level of equilibrium national income. This is known as the multiplier effect.

The Multiplier Effect is the change in income to the permanent change in the flow of From the diagram below we can see, that an increase in. Every time there is an injection of new demand into the circular flow there is likely to be a multiplier effect.
With a low multiplier, by contrast, changes in aggregate demand will not be multiplied much, so the economy will tend to be more stable.
Harrod-Domar in their famous dynamic growth models emphasized that investment not only creates demand but also new productive capacity. The multiplier effect in case of upward sloping curve is shown in Fig.

In fact, during the depression period of s, it actually happened so and is evident from Table Further, even when there is no preexisting excess capacity in the industries increase in investment leads to the increase in demand for consumption goods which in turn causes further rise on investment to meet that consumption demand.
Explain and demonstrate the multiplier graphically using the income-expenditure model The idea behind the multiplier is that the change in GDP is more than the The graph shows the multiplier effect in the expenditure-output model: an.
Multiplier effect, has very important implications for economic planning and For Keynes there was a difference between equilibrium income (the level toward. The consumption function can also be illustrated with an equation or a graph.
As a result, consumption expenditure declines due to this wealth effect.
However, we can express multiplier in a simpler form.
This looks rather simple but during the early s it was not understood at all. For professional athletes, out of a dollar earned, 40 cents goes to taxes, leaving 60 cents. Now, consider the impact of money spent at local entertainment venues other than professional sports. In this case, the value of the multiplier will be equal to one.
Reading The Multiplier Effect Macroeconomics
The Keynesian multiplier effect is very small in developing countries like India since there is not much excess capacity in consumer goods industries.

|Keynes ignored the time-lag in the process of income generation and therefore his multiplier is also called instantaneous multiplier.
Rao and his followers, for the working of multiplier in raising national income and employment was that the supply of raw materials, financial capital must be sufficiently elastic so that when aggregate demand increases as a result of multiplier effect of increase in investment the supply of output could be increased adequately to meet this higher demand for goods and services.
The size of multiple is determined by the value of marginal propensity to consume. Indeed, the classical economists argued that the increase in the supply of savings would lead to the fall in the rate of interest which would induce increase in planned investment.
Now suppose autonomous investment expenditure which is independent of changes in price level increases by AI.
