On this ground alone, the theory has been severely criticized by D. Furthermore fiscal action cannot be left to the vagaries and reservations Online Live Tutor Devising of Fiscal Strategies: We have the best tutors in Economics in the industry. The third condition required for the working of multiplier in real terms was that there should be involuntary open unemployment so that when aggregate demand for goods increases as a consequence of new investment, the adequate supply of workers must be forthcoming to be employed in the production processes of various industries. The multiplier would then be low. Thus principle presumes state interference in fiscal dealings. The accelerator principle states that changes in the level of current income, leading to changes in output of consumer goods, will lead to proportionately greater, or accelerated changes, in the output of capital goods, i. Kahn developed the concept of multiplier with reference to the increase in employment, direct as well as indirect, as a result of initial increase in investment and employment.
The extent of the multiplier effect in increasing domestic business activity is dependent upon the and. In the tableau économique, one sees variables in one period time t feeding into variables in the next period time t+1 , and a constant rate of flow yields geometric series, which computes a multiplier. Given the demand function for money M d , the decline in the real money supply will cause rate of interest to rise. In contrast, higher spending in a small and open economy, such as Monaco to take an extreme example, will be met primarily by supplies originating elsewhere. In other words, a community with a high propensity to save is affected less by the reverse operation of the multiplier than the one with a low propensity to save.
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. This has not always been the case. Therefore, the money used for payment of taxes does not appear in the successive rounds of consumption expenditure in the multiplier process, and the multiplier is reduced to that extent. 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. In the words of S.
In that case as a result of some initial increase in investment, income would go on rising indefinitely. It may be pointed out that thanks to the spread of green revolution technology expansion in irrigation facilities in various states of India, food grain production can be adequately increased in response to rising demand for food grains. However, if due to some bottlenecks output of goods cannot be increased in response to increasing demand, prices will rise and as result the real multiplier effect will be small. Kahn developed the concept of multiplier with reference to the increase in employment, direct as well as indirect, as a result of initial increase in investment and employment. In such circumstances, policy to increase aggregate demand and total business activity by means of fiscal measures may treat additional purchases and reductions in taxes as interchangeable near equivalents, with the changes in the net difference between spending and taxation identified as the deficit-financed. What is the multiplier effect? When investment declines from I to K the income also declines from Y 1 to Y 2 and a new equilibrium E 2Y 2 is obtained. Now, higher the marginal propensity to consume b or the lower the value of marginal propensity to save s , the greater the value of multiplier.
To get rid of depression and remove unemployment, Government investment in public works was recommended even before Keynes. Multiplier effect of new investment can be further increased, if investment package is quite diversified covering a large number of industries including agriculture so that monetary demand and income generated by any one industry can be adequately met by increase in output capacity in other industries. This is because, according to Keynes, the effort to save more by all in a society will lower the aggregate demand for goods and services resulting in a drop in the level of national income. In our above analysis of the multiplier process we have taken a closed economy, that is, we have not taken into account imports and exports. That is, comparative statics calculates how much one or more variables change in the short run, given a change in one or more exogenous variables. Keynes took the idea from Kahn and formulated the Investment multiplier.
Further, the decline in consumption due to more saving would cause the multiplier to work in reverse, that is, the multiplier would operate to reduce the level of consumption and income by a magnified amount. This 'first round effect' is the big boost to spending within the economy. Assuming the marginal propensity to consume as ½, let us assume further that there is an investment of Rs. The initial expenditure by the state added more money to the economy than the simple cost of the bridge. The process of income propagation through multiplier does not work in the forward direction only.
Each participant who experiences an increase in disposable income then spends some portion of it on final consumer goods, according to his or her , which causes the cycle to repeat an arbitrary number of times, limited only by the spare capacity available. The multiplier effect in an open economy As well as calculating the multiplier in terms of how extra income gets spent, we can also measure the multiplier in terms of how much of the extra income goes in savings, and other withdrawals. . They argued that in underdeveloped countries like India due to under developed nature of their economies, there was acute scarcity of raw materials, other intermediate goods such as steel, cement and financial capital which put great obstacles for the working of multiplier in real terms. But this constancy of marginal propensity to consume is a realistic assumption, since all available empirical evidence shows that marginal propensity to consume is very stable in the short run. Classified investment being induced by the profit motive can help only when the public investment has shaped a constructive circumstance for the previous.

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. 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. In other words, multiple increment in income as a result of a given net increase in investment does not only take place in money terms but also in terms of real output, that is, in terms of goods and services. It is worth noting that multiplier not only works in money terms but also in real terms. Increase in Prices: Price inflation constitutes another important leakage in the working of the multiplier process in real terms. This fall in aggregate expenditure curve is due to the adverse effects on wealth or real balances, interest rate and net exports.
