What is the term for a persistent decline in the general price level?

जब किसी अर्थव्यवस्था में सामान्य मूल्य स्तर लगातार घटता रहता है, तो उस स्थायी गिरावट को क्या कहा जाता है?

A persistent decline in the general price level of goods and services in an economy is termed deflation. It is the opposite of inflation. Deflation typically occurs due to a decrease in aggregate demand or excess supply. While it increases the purchasing power of money, it is often harmful as consumers delay purchases expecting further price drops, leading to reduced production, layoffs, and economic slowdown. Prolonged deflation can cause a deflationary spiral, worsening recession. It is commonly associated with periods of economic depression, such as the Great Depression.
