Saving is defined as that portion of current income (this year's) not paid out in taxes or in the purchase of consumer goods, but which flows into bank accounts, insurance policies, bonds and stocks, and other financial assets. Reasons for saving are many and diverse, but they center around security and speculation. households save to provide a nest egg foe unforeseen contingencies-sickness, accidents, unemployment-for retirement from the work force, or to finance the education of children. On the other hand, saving might occur for speculation. One might channel part of one's income to the purchase of securities, speculating as to increases in their monetary values.
