This study proposes a framework to explainpeople's risk preferences in a consistent manner and aims to quantitativelyevaluate risk preferences using this framework. The framework divides risk into threecategories: pure risk, speculative risk, and lottery risk. This explains theseemingly contradictory mix of risk-averse preferences for insurance andrisk-loving preferences for lotteries. The research plan is to conduct multiplesurveys over a two-year period and to measure the risk premium for each of thethree categories. This year's objectives were (1) to examinethe 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 progressedas expected. In FY2023, we plan to analyze the dataobtained from the first survey and measure the risk premium, design and conductthe second and subsequent surveys, analyze the data, and publish the results inforeign or domestic journals.
