The life-cycle hypothesis says that people save:
for retirement. out of habit. in order to become wealthy. to increase the growth rate of the economy.
In Aesop's fable of the grasshopper and the ant,
the ant resembles a person who acts in the way the life-cycle hypothesis predicts. the grasshopper resembles a person who acts in the way the life-cycle hypothesis predicts. both resemble people who act in the way the life-cycle hypothesis predicts. neither resembles a person who acts in the way the life-cycle hypothesis predicts.
