Discounting: The Science of Time Preference

When we think about the future, we often think about the trade-offs we'll have to make between present and future rewards. Should we indulge in instant gratification, or should we delay gratification in order to receive a larger payoff down the line? These are questions of time preference, the degree to which we value present versus future rewards. The scientific study of time preference is known as discounting, and it has significant implications for economics, psychology, and decision-making.

What is Discounting?

At its core, discounting is a mathematical model that captures the idea that future rewards are worth less than immediate rewards. In other words, the further into the future a reward is, the less we value it. This is known as temporal discounting, and it's a fundamental aspect of human decision-making. To illustrate this point, imagine that I offered you $100 today or $100 one year from now. Most people would choose the $100 today, because we tend to value immediate rewards more than hypothetical future rewards.

The Economics of Discounting

Discounting has significant implications for economics. For example, economists use discounting to calculate the present value of future cash flows, which is an important concept in finance. One of the key insights from discounting is that it allows us to compare apples to oranges, so to speak. When considering an investment that will pay off in the future, we use discounting to account for the time value of money. This means that if we expect to receive $100 in one year, and we use a discount rate of 10%, then the present value of that cash flow is only $90.91.

The Psychology of Discounting

Discounting also has implications for our mental health and well-being. Studies have shown that people who have a lower time preference, meaning they are more willing to delay gratification in order to receive larger rewards in the future, tend to be more successful in a variety of areas, including academic achievement, financial stability, and physical health. Conversely, people with high time preference, who tend to seek immediate gratification, are more likely to struggle with addiction, impulsivity, and poor decision-making. Understanding the science of time preference can help us identify strategies for improving our ability to make sound, long-term decisions.

In conclusion, discounting is a fundamental concept in economics and psychology that helps us understand how we value present versus future rewards. By modeling the time value of money, discounting allows us to compare different streams of cash flows and make better financial decisions. Additionally, our individual time preferences have significant implications for our well-being and success in life, making it important for us to understand our own tendencies and learn strategies for delaying gratification when necessary.
