Deflation

macroeconomics
Definition
A sustained decrease in the general price level of goods and services, the opposite of inflation.

Explanation

Deflation sounds appealing (lower prices!) but is economically dangerous. When prices fall, consumers delay purchases expecting further declines, reducing aggregate demand. Companies cut production and jobs. Debt burdens increase in real terms because borrowers repay with more valuable dollars. Japan experienced deflation from the 1990s through 2010s, resulting in three 'lost decades' of economic stagnation. Central banks fear deflation more than moderate inflation, which is why the Federal Reserve targets 2% inflation rather than 0%.
