Keynes

Keynes refers to John Maynard Keynes, the British economist whose theories fundamentally reshaped modern economic thought.

His ideas, developed during the Great Depression, argued that government spending and intervention could stabilize economies during downturns.

The adjective Keynesian describes economic policies based on his work, particularly deficit spending to stimulate demand: Keynesian economics fell out of favor in the 1980s but resurged during the 2008 financial crisis.

To invoke Keynes is often to advocate for active government economic management.
