Historical Context
Time preference is a fundamental concept in economics that deals with how individuals or societies prioritize consumption at different points in time. Historically, it has roots in classical economics and was prominently discussed by pioneers such as Adam Smith and later by John Maynard Keynes. The idea reflects our natural inclination to prefer rewards today rather than in the future, and it underpins many economic models and theories.
Types/Categories
- Positive Time Preference: Preferring current consumption over future consumption.
- Negative Time Preference: Preferring future consumption over current consumption, which is rare and typically associated with very specific contexts or cultures.
- Neutral Time Preference: Indifference between immediate and future consumption.
Key Events
- The 18th Century: The classical economists laid the foundations of time preference in the context of interest rates and savings.
- 1930s: John Maynard Keynes further developed the concept in his work on consumption functions and the psychological law of consumption.
- 20th Century: Behavioral economics and psychologists like Walter Mischel with the “Marshmallow Test” contributed to understanding time preference from a cognitive and behavioral standpoint.
Detailed Explanations
Time preference is a critical determinant of economic behaviors such as saving, investing, and consumption. It impacts interest rates, inflation, and overall economic growth. Individuals with a high time preference tend to spend more now and save less, whereas those with a low time preference are more inclined to save and invest for future benefits.
Mathematical Formulas/Models
The standard model to represent time preference is the Discounted Utility Model (DU Model). The utility of future consumption is discounted by a factor that represents the individual’s time preference rate.
where:
- \( U \) = Total utility
- \( u(C_t) \) = Utility of consumption at time \( t \)
- \( \rho \) = Time preference rate
- \( T \) = Time horizon
