In economics, time preference (or "discounting") is the relative valuation placed on a good at an earlier date compared with its valuation at a later date.
There is no absolute distinction that separates "high" and "low" time preference, only comparisons with others either individually or in aggregate. Someone with a high time preference is focused substantially on his well-being in the present and the immediate future relative to the average person, while someone with low time preference places more emphasis than average on their well-being in the further future.
Time preferences are captured mathematically in the discount function. The higher the time preference, the higher the discount placed on returns receivable or costs payable in the future.
The time preference that an individual exhibits at any given moment is determined solely by their personal preferences. As such, if one "prefers" to save his money but cannot do so in the present, he is still considered to have a low time-preference. One of the factors that may determine an individual's time preference is how long that individual has lived. An older individual may have a lower time preference (relative to what he had earlier in life) due to a higher income and to the fact that he has had more time to acquire durable commodities (such as a college education or a house).
The time preference theory of interest is an attempt to explain interest through the demand for accelerated satisfaction. This is particularly important in microeconomics.
In the neoclassical theory of interest due to Irving Fisher, the interest rate determines the relative price of present and future consumption. Time preference, in conjunction with relative levels of present and future consumption, determines the marginal rate of substitution between present and future consumption. These two rates must necessarily be equal, and this equilibrium is brought about by the relative prices of present and future consumption.

Famous quotes containing the words time and/or preference:
“The vines of her arms
didn’t cling to the ends of his clothes,
or did she plant herself in the doorway,
hurl herself at his feet,
or utter the word “Stay!”
But as that fool began to go
at the time when it was dark with swarming clouds,
the slim girl blocked her lover’s way
with only a rising river
made with her flood of tears.”
—Amaru (c. seventh century A.D.)
“He that has his chains knocked off, and the prison doors set open to him, is perfectly at liberty, because he may either go or stay, as he best likes; though his preference be determined to stay, by the darkness of the night, or illness of the weather, or want of other lodging. He ceases not to be free, though the desire of some convenience to be had there absolutely determines his preference, and makes him stay in his prison.”
—John Locke (1632–1704)
