Review Questions

• How did Keynes challenge classical economic theories with his ideas about government intervention?
  • Keynes challenged classical economic theories by arguing that markets do not always self-correct and can remain in prolonged states of disequilibrium, such as during recessions. He believed that without government intervention, economies could experience high unemployment and insufficient demand for extended periods. His proposal that active fiscal policy could stabilize economies was a significant departure from the laissez-faire approach typical of classical economics.
