Who is father of new economics?

The title "Father of New Economics" is often attributed to John Maynard Keynes, a British economist whose ideas fundamentally transformed economic theory and policy during the 20th century. His work, particularly in "The General Theory of Employment, Interest, and Money" published in 1936, challenged classical economics and emphasized the role of government intervention in stabilizing economic cycles. Keynesian economics laid the groundwork for modern macroeconomic policy and has influenced economic thought ever since.
