Which would you prefer: one piece in 10 years, or two pieces in 10 years and a week?
Is there any contradiction in your choice?
Question 1: Which would you prefer: A, or B?
A. One piece of chocolate in 10 years
B. Two pieces of chocolate in 10 years and a week
Question 2: Which would you prefer: C, or D?
C. One piece of chocolate right away
D. Two pieces of chocolate in a week
In fact, these questions amount to the same thing, except for the condition “in 10 years.” Economists tend to assume that those who are patient enough to choose B in question 1 will naturally choose D in question 2, and vice versa. But that’s not always the case. Generally speaking, subjective discount rates for rewards decrease the farther one goes into the future (people can wait), but increase the closer they are to the present (people can’t wait). This is referred to as the “preference reversal over time” in behavioral and neuro-economics, which is described by the following “hyperbolic” time-discount function.
The fusion of behavioral economics and neuroscience:
Neuroeconomics as a science that liaises between these two
Behavioral economics is based on the concept that humans behave according to their desires, and neuroscience addresses the relationship between mind and brain. When these sciences confront problems beyond their frameworks, neuroeconomics, which is a fusion of the two, plays a role in solving those problems. This science focuses on using neurotransmitters, i.e., the micro level, to elucidate interpersonal interactions, i.e., the macro level of natural science. The ability to address issues regardless of their levels is a fresh lure of this science. Hokkaido University is blessed with a number of experts on economics, enabling the Faculty of Letters to perform joint research with the School of Science and the School of Medicine. Those who are interested in neuroeconomics are recommended to acquire a basic knowledge of biology, psychology and economics, in that order, which will help you to smoothly commence your technical studies.
