Keynesian Economics

Definition

Keynesian economics is an economic theory developed by John Maynard Keynes during the Great Depression, emphasizing the role of government intervention in stabilizing the economy. It argues that aggregate demand, which includes consumer spending and investment, drives economic growth and that during times of recession, increased government spending can help boost demand and pull the economy out of a downturn. This theory reshaped economic policies around the world and has had significant implications for industrialization, political thought, and modern economic systems.
