Definition

Noun: * An economic theory and policy approach: Keynesianism is a macroeconomic theory based on the ideas of the 20th-century economist John Maynard Keynes. It argues that aggregate demand (total spending in the economy) is the primary driver of economic output and employment. A core tenet is that during recessions, private sector demand is often insufficient, so active government intervention through fiscal policy (e.g., spending and taxation) and monetary policy is necessary to stabilize the economy, reduce unemployment, and moderate business cycles.
