Human action and the interest rate
People value present goods more highly than future goods. For instance, an apple available today is considered more valuable than the same apple available in, say, one month. This is expressive of time preference — which is an undeniable fact, a category of human action.
The sentence “Humans act” is a logically irrefutable truth. It cannot be denied without causing a logical contradiction. By saying “Humans can not act”, you act and thus contradict your very statement.
From the true insight that humans act we can deduce that human action takes place in time. There is no timeless human action. Were it otherwise, people’s goals would be instantaneously reached, and action would be impossible — but we cannot think that we cannot act.

If one US-dollar available in a year is trading at, say, 0.95 US-dollar, it means that the market interest rate is 5.0% (the calculation is: [0.95 / 1 – 1]*100).

If peoples’ time preference declines, the discount on future goods vis-à-vis present goods drops, and so does the market interest rate — meaning that people wish to save more and consume less out…
