In economics, a state where the general level of prices in an economy remains relatively constant over a defined period is a desired outcome. This implies that inflation, a sustained increase in the general price level, and deflation, a sustained decrease, are both minimal and predictable. For example, a central bank might target an inflation rate of 2% per year as consistent with this objective.
Maintaining a stable price level is considered important because it fosters economic growth, encourages investment, and protects the purchasing power of consumers. Unpredictable fluctuations in prices create uncertainty for businesses, making it difficult to plan future production and investment. A stable price environment promotes confidence, leading to increased economic activity. Historically, periods of significant inflation or deflation have often been associated with economic instability and hardship.
