In economics, a deflationary spiral is a situation where decreases in price lead to lower production, which in turn leads to lower wages and demand, which leads to further decreases in price. Since reductions in general price level are called deflation, a deflationary spiral is when reductions in price lead to a vicious circle, where a problem exacerbates its own cause. The Great Depression was regarded as a deflationary spiral.
Economic theory
A deflationary spiral is the modern macroeconomic version of the general glut controversy of the 19th century.
