研究成果概要

This study proposes a framework to explain people's risk preferences in a consistent manner and aims to quantitatively evaluate risk preferences using this framework.

 

The framework divides risk into three categories: pure risk, speculative risk, and lottery risk. This explains the seemingly contradictory mix of risk-averse preferences for insurance and risk-loving preferences for lotteries.

 

The research plan is to conduct multiple surveys over a two-year period and to measure the risk premium for each of the three categories.

 

This year's objectives were (1) to examine the design of the survey, particularly the ease of understanding the survey questions by respondents, (2) to verify the validity of the method by conducting the first round of the survey, and (3) to obtain 1,000 valid responses.

As of the end of March, (1) to (3) above progressed as expected. 

In FY2023, we plan to analyze the data obtained from the first survey and measure the risk premium, design and conduct the second and subsequent surveys, analyze the data, and publish the results in foreign or domestic journals.
