Review Questions

• How did John Maynard Keynes's ideas challenge traditional economic theories?
  • Keynes's ideas challenged traditional economic theories by emphasizing that aggregate demand is crucial for economic stability and growth, rather than merely focusing on supply. His work highlighted that during periods of recession, it is necessary for governments to actively intervene in the economy through fiscal policies such as increased spending to stimulate demand. This was a shift from classical economics, which assumed markets were self-correcting and did not require government intervention.

  • Keynes's principles had a significant impact on the development of the Bretton Woods Agreement, which aimed to create a stable international monetary system after World War II. He advocated for fixed exchange rates and the establishment of institutions like the International Monetary Fund (IMF) to provide financial stability and prevent competitive devaluations. His belief in managing aggregate demand on an international scale helped shape the framework for post-war economic cooperation and stability among nations.
