John Maynard Keynes

John Maynard Keynes is arguably the most influential economist of the 20th century. His work fundamentally shifted economic thought by emphasizing the role of aggregate demand in driving economic activity and the necessity of government intervention during recessions. In 2025, his theories remain the primary toolkit for policymakers managing economic cycles. His ability to explain the 'paradox of thrift' and the importance of liquidity preference continues to guide central bank strategies and fiscal stimulus packages worldwide, making him an essential figure for understanding modern economic stability.
