Time is money! The fact that a dollar received tomorrow is not equivalent to a dollar in hand today. It is the fact that money always can earn a positive return that lends importance to the time dimension. A dollar given up today is not the equivalent of a dollar received in the future as long as there exists the alternative of earning a positive return on the dollar during the interim.
Is the time value of money only dependent on the affordance of a person or an organization to invest the equivalent amount of money?
