Review Questions

• How did John Maynard Keynes' ideas challenge classical economic theories?
  • Keynes challenged classical economic theories by arguing that economies are not always self-correcting and can remain in prolonged states of unemployment. He believed that during downturns, insufficient aggregate demand could lead to a failure of the economy to return to full employment without government intervention. This marked a significant shift from the classical view that markets naturally adjust and correct themselves over time.

  • In Keynesian economics, fiscal policy plays a crucial role as it is used by governments to manage economic cycles. Keynes advocated for increased government spending during periods of recession to stimulate demand and create jobs. By doing so, he believed that governments could mitigate the effects of economic downturns and promote recovery, thus highlighting the necessity for active governmental involvement in managing the economy.

This blending of free-market principles with state intervention led to systems where governments manage economic activities to correct market failures and promote social welfare, shaping modern economic practices across various nations.
