Solution

Paradox of thrift refers to a situation in which people tend to save more money, thereby leading to a fall in the savings of the economy as a whole. In other words, when everyone increases his/her saving-income proportion i.e. MPS (s), then, the aggregate demand will fall as consumption decreases. This will further lead to a decrease in employment and income level and finally this will reduce the total savings for the economy. This concept was suggested by Keynes wherein increased saving at individual levels will gradually lead to the slowdown of economy in terms of circular flow of income.
