The most important leakages from the circular flow of income are the following: i. This extra investment will generate an extra income of Rs100 crores in the first round. The concept of a multiplier effect is applied in many other areas, such as unemployment benefits and tax policy. This approach, meant to help overcome a shortage of private investment, measured the amount of government spending needed to reach a level of income that would prevent. In such a situation, investment does not help in generating employment or increasing income.

## Keynes' Theory of Investment Multiplier (With Diagram)

What is its importance in the theory of income deterĀ­mination? Let us now suppose that due to new investment of Rs. Obviously the value of the multiplier is equal to 3. Milton Friedman, among others, showed that the Keynesian multiplier was both incorrectly formulated and fundamentally flawed. This explains the paradoxical feature of an economy gripped by recession. The numerical values of the multiplier in these three cases are 2.

## Explaining the Multiplier Effect

Income change has to conĀ­tinue until additional saving of Rs. Thus total consumption C comprises two components i Autonomous Consumption not influenced by income, and ii Induced Consumption bY influenced by income. Thus there is divergence between the point of equilibrium attained by an economy and the point of equilibrium at which an economy has full employment of resources. If they cannot be plugged altogether, they should be reduced or the propensity to consume should be increased or propensity to save should be reduced, otherwise the new investment will not have full effect in increasing income and employment. The multiplier concept is concerned with original investment as a stimulus to consumption and thereby to income and employment. Keynes has mentioned three motives for holding ready cash for liquidity preference, viz.

However, none can undermine the importance of the investment multiplier in the economic analysis. Many governments in developed nations have been introducing fiscal austerity programmes ā cutting spending and lifting taxes in a bid to lower their budget deficits.

Stock Exchange Transactions: It is often observed that a major portion of the new income genĀ­erated in the economy is utilised to buy old bonds and securities from others.

## Explain the concept of investment multiplier.

This shows that the flatter the saving schedule, the larger the value of the multiplier. But this is not all. When investment in an economy rises, it has a multiple and cumulative effect on national income, output and employment. However, if due to some bottlenecks output of goods cannot be increased in response to increasing demand, prices will rise and as a result the real multiplier effect will be small. Had there been no saving and as a result marginal propensity to consume were equal to 1, the multiplier would have been equal to infinity.

## Investment Multiplier

At the lower level of national income, the savings fall to the original level but consumption will be less than before which implies that the people would become worse off. So, there will be no further increase in income. Now suppose autonomous investment increase by Rs. To the extent they follow the policy of saving a certain portion of their net profits the consumption spendĀ­ing of shareholders fails to increase correspondingly. In such case, value of multiplier will be more. In other words, developing countries really benefit from government investment over government consumption. But as income rises, a portion of income will be spent on consumpĀ­tion goods and the balance saved.

## What is investment multiplier and its value?

There is less than full employment in the economy economy is operating at excess capacity. One limiting case occurs when the marginal propensity to consume is equal to one, that is, when the whole of the increment in income is consumed and nothing is saved. When output of consumer goods cannot be easily increased, a part of the increases in the money income and aggregate demand raises prices of the goods rather than their output. It is only when the level of full employment has been reached that investment and consumption become competitive instead of being complementary; then increase in one will reduce the other, one will be at the expense of the other. This is the peak of the trade cycle characterized by high prices, rising prices, rising wages, expanding production, high employment levels sometimes shortage in the supply of labor and towards the end of the period bottle necks in production begin to appear. Then the multiplier is M. Business cycle analysts, central bankers, and policy planners study investment multipliers on an aggregate level to observe the general flow of wealth in an economy, and to better understand certain variables such as employment, prices and the velocity of the money supply.

## Multiplier and Accelerator

It is shown as Short comings of the accelerator principle It works on the assumption that the capital output ratio is constant thorough out the economy but in real economies, the capital output level changes within sectors and with time It assumes that capital equipment is efficient throughout the given period but this is not true It assumes that the volume of sales is constant throughout the years but the volume of sales usually changes from one period to another The accelerator is not really practical because in real life there is a time lag between the increase in consumption and the increase in investment that may result. How much increase will there take place in income? But it is not necessary that all the money raised through taxation is spent by the Government as it happens when Government makes a surplus budget. Source: Adapted from the Economist and other news reports, July 2013. Some economists reckoned the spending would do little to help the economy. But besides saving, there are other leakages in the process of income generation which reduce the size of the multiplier. But the process of income generĀ­ation cannot continue indefinitely. As a result, employment and income will also rise.

When individual lenders have a relaxed attitude and are amenable to lend interest rate is low but when they want to discourage borrowing the interest rate is high. What is a simple definition of the multiplier? For these reasons the value of the multiplier may get reduced. Competition among labour to seek employment would lead to fall in wage rate. This extra money will be reĀ­ceived by industries that supply necessary materials for the new factories and those that actually underĀ­take the construction work. In the multiplier theory, the important element is the multiplier coefficient, K which refers to the power by which any initial investment expenditure is multiplied to obtain a final increase in income. These people may spend the extra income in the retail, consumer goods, or service industries, also boosting the income of workers there. It goes to the credit of Keynes that with his multiplier theory he was able to resolve the paradox of thrift.

Thus Two Limiting Cases of the Value of Multiplier: There are two limiting cases of the multiplier. How to determine its value? Induced spending falls by Rs. This, in its in turn, will lead to further multiplier process. The Great Depression led to break down of Classical theory. Where did it come from and why is there so much disagreement about it? A part of his income goes out in repaying such debts and is not utilised either in consumption or in productive activity. We observe that the sum of all of this new expenditure is approximately Rs. C + I represents aggregate demand curve.
