Cover Story: Asset accumulation is critical in Japan due to the gap between life expectancy and retirement age. Hyperbolic discounting, driven by present-biased preferences, hampers savings for later life, but its empirical effects on those aged 65+ and across wealth levels remain understudied. This study analyzes data from 6709 Japanese investors aged 65+ using probit regression, examining wealth thresholds of JPY 20M, 30M, 50M, and 100M. Results reveal that hyperbolic discounting significantly impairs accumulation at JPY 100M but not at lower levels, reflecting its impact on long-term savings and investments. Recommendations include automatic savings plans, financial literacy programs, and behavioral tools to improve late-life financial security. View this paper
