This generates demand for replacement investment. Keynes in his seminal work ‘General Theory of Employment, Interest and Money’ made an important contribution to the analysis of the causes of business cycles. A Keynesian believes […] Now, the multiplier works to magnify the effect of increase in investment on raising aggregate demand. Thus, just as the collapse of marginal efficiency of capital is the main cause of the upper turning point, similarly the lower turning point, i.e., changes from recession to recovery is due to the revival of the marginal efficiency of capital, that is, expected rate of profit. In spite of its various merits, the Hicksian theory of trade cycle suffers from the following weaknesses its fundamental shortcoming is that Hicks assumes a fixed value of the multiplier during the fixed phases of the cycles.

Secondly, fluctuations in investment demand are caused by changes in expectations of businessmen regarding making of profits (that is, marginal efficiency of capital). Thus, Samuelson combined the accelerator principle with the multiplier and showed that the interaction between the two can bring about cyclical fluctuations in economic activity.

In Keynesian Theory of Trade Cycles, the marginal efficiency of capital has great significance than the rate of interest. If the aggregate demand is increasing, economic expansion will take place. The turning point from expansion to con­traction is thus caused by a sudden collapse in marginal efficiency of capital. Changes in total expenditure will imply changes in effective demand and will lead to changes in income and employment in the country. The boom conditions themselves contain the very seeds of their own destruction. But whether a fresh investment will be undertaken will depend upon the marginal efficiency of capital.
