What is the primary reason the aggregate expenditures model was developed by John Maynard Keynes?
Explanation
John Maynard Keynes developed the aggregate expenditures model during the 1930s to explain the prolonged high unemployment of the Great Depression, challenging the classical view that economies automatically adjust to full employment.
