The general decrease in prices of goods and services is known as deflation. It is the opposite of inflation, which is a general increase in prices. Deflation occurs when there is a decrease in the demand for goods and services and/or an increase in the supply of goods and services. When prices go down, the purchasing power of money increases, which can stimulate economic growth and encourage consumers to spend more. However, deflation can also lead to economic problems such as lower profits for businesses, lower wages for workers, and increased unemployment.
