The Paradox of Thrift is an economic theory that states that if everyone saves their money, it can be detrimental to actually achieving economic growth. This concept states that an individual needs to be pushing their current spending in order to help to drive future spending. These current spends made will then help to increase the flow of money throughout the economy; creating a greater level of economic stability and growth.

In order to adhere to the Paradox of Thrift, it is necessary to lower interest rates in the times of an economic recession. The idea behind this is that a lowered rate of interest makes it more likely that consumers will spend their money, leading to a higher level of money circulation and economy stimulation. This concept has been accepted by economists in the past, but there are also some criticisms of it.

The most prominent criticism of the Paradox of Thrift is that it ignores Say’s law. According to Say’s law, it is necessary for there to be an investment in capital goods before a level of spending can be achieved. This means that it is necessary to put money into certain areas of the economy to make an impact before any customer spending will begin.

At the same time, the Paradox of Thrift theory doesn't take into account inflation or deflation of prices in the economy. When prices within the economy suddenly increase, this can lower the level of spending throughout the economy. If prices then decrease, this will also change customers spending habits, and make it more difficult to help generate economic growth with the Paradox of Thrift.

The Paradox of Thrift is an interesting concept with some validity, but it is also missing certain key analysis points. It is necessary for an economist to consider all the aspects of the current economy before an economic growth initiative can be successful. The Paradox of Thrift does provide an example of how individual spending can be influential to an economies success, but there are many other variables that need to be taken into account.
