Title: Toward the wider adoption of health promotion insurance – Focusing on policyholders’ characteristics –
Content: Health promotion insurance, introduced in Japan in 2018, is expected to contribute to reducing medical expenses and alleviating the burden on social security by extending healthy life expectancy. However, it has yet to achieve widespread adoption. This report uses individual-level data from the 2024 National Survey on Life Insurance to conduct logistic regression analysis, identifying common characteristics among policyholders and clarifying factors that could promote wider adoption.
MNP (Day 1) 3rd place: Team 2 (OBAYASHI Yui, KONDO Sho, TOMIKURA Rin, TOMITA Yusuke, YAMAZAKI Aina)
Title: Strategic use of BI Insurance to enhance corporate resilience
Content: The importance of Business Interruption Insurance (BI Insurance) is growing. This insurance compensates for lost operating profits during business interruptions caused by diverse and increasingly complex risks, including natural disasters, and covers the costs required to maintain normal business operations. This report quantitatively evaluates the impact of BI Insurance on corporate business interruption risks. To demonstrate the importance of BI Insurance, the team employs Monte Carlo simulation analysis, highlighting the necessity for promoting its adoption and widespread use among Japanese companies.
