Time-preference

Time Preference is the higher value that a person puts on consumption now comared to consumption in the future

In Capital and Interest the Austrian economist Eugen von Boehm-Bawerk built upon the time-preference ideas of Carl Menger, insisting that there is always a difference in value between present goods and future goods of equal quality, quantity, and form. Furthermore, the value of future goods diminishes as the length of time necessary for their completion increases.

Boehm-Bawerk cited three reasons for this difference in value. First of all, in a growing economy, the supply of goods will always be larger in the future than it is in the present. Secondly, people have a tendency to underestimate their future needs due to carelessness and shortsightedness. Finally entrepreneurs would rather initiate production with goods presently available, instead of waiting for future goods and delaying production.
