Keynesian economics

Definition

Keynesian economics is an economic theory that emphasizes the role of government intervention in stabilizing the economy, particularly during periods of recession. It posits that increased government spending and lower taxes can stimulate demand, thereby promoting economic growth and reducing unemployment. This approach became especially significant during the Great Depression, when traditional economic theories failed to address the crisis effectively.
