Deflation is the continuous decrease in prices of goods and services. Deflation occurs when the inflation rate becomes negative (below zero) and stays there for a longer period...
During deflation the price of goods and services is falling and consumers will tend to delay their purchases until prices fall further. This will cause for a lower production, lower wages and demand which will lead to further decrease in prices. This is known as deflationary spiral.
It is a situation when decrease in the prices leads to lower production, lower wages and demand, which can lead to further decrease in the prices. A deflationary spiral is when decrease in prices lead to a vicious circle (a trouble leads to another that aggravates the first).
