• How did John Maynard Keynes's theories reshape the understanding of economic cycles?
  • John Maynard Keynes's theories reshaped the understanding of economic cycles by introducing the concept that government intervention is essential during periods of economic downturns. He highlighted that private sector demand could be insufficient, leading to prolonged recessions. This idea shifted the focus from self-correcting markets to the need for active fiscal policies that stimulate aggregate demand to stabilize the economy.
