Related economic concepts include: deflation, a general falling in price level; disinflation, a decrease in the rate of inflation; hyperinflation, an out-of-control inflationary spiral; stagflation, a combination of inflation and slow economic growth and rising unemployment; and reflation, which is an attempt to raise prices to counteract deflationary pressures.

In classical political economy, inflation meant increasing the money supply, while deflation meant decreasing it (see Monetary inflation). Economists from some schools of economic thought (including some Austrian economists) still retain this usage. In contemporary economic terminology, these would usually be referred to as expansionary and contractionary monetary policies.
