According to this paradox of thrift, the attempt by the people as a whole to save more for hard times such as impending period of recession or unemployment may not materialize and in their bid to save more the society in-fact may not only end up with the same savings or, even lower savings but also in the process cause their consumption or standard of living to decline.
In this instance we are concerned about changes to the money supply in the nation which originate in decisions by central banks regarding the increase or decrease in banking reserves. The huge decline in national income and the emergence of unemployment in the USA, UK and other industrialized capitalist countries during the period of depression is graphically shown in Fig.
For any given interest rate, the aggregate demand function shifts downward, the equilibrium level of aggregate output falls, and the IS curve shifts to the left. Therefore, multiplier in actual practice is less than infinity.
This will reduce the value of the multiplier. This phenomenon is also observed with an autonomous rise in net exports unrelated to the interest rate. Besides, in developing countries like India, there is not much excess capacity in many consumer goods industries, especially in agriculture and other wage-goods industries.

To begin with, in the top panel of Fig. It is worth noting that multiplier not only works in money terms but also in real terms.
