Review Questions

• How did John Maynard Keynes' ideas challenge classical economic theories, particularly regarding government intervention?
  • Keynes challenged classical economics by arguing that markets do not always self-correct and that prolonged periods of high unemployment could persist without government intervention.

  • Keynesian economics had a profound impact on fiscal policy by promoting the idea that during recessions, governments should increase public spending and lower taxes to boost aggregate demand. This approach became a key strategy for mitigating economic downturns, allowing governments to take proactive steps to counteract unemployment and stimulate growth. The implementation of Keynesian principles can be seen in various historical contexts, such as during the Great Depression and in response to the 2008 financial crisis.
