This study provides empirical evidence consistent with the existence of adverse selection in the life insurance market. An analysis of micro data from more than 1.6 million automatic renewal term life insurance contracts, issued by a Japanese life insurance company, reveals that owing to medical and other selections, neither adverse selection nor moral hazard problems could not be recognized with an automatic renewal term life insurance (before renewal). However, after the renewal, adverse selection and moral hazard did occur in the subsequent 10 years. Considering intensifying price competition, a review of automatic renewal of term life insurance may be required for equal distribution of the financial burden amongst policyholders and for the financial soundness of life insurance companies.

本研究提供了与寿险市场存在逆向选择一致的实证证据。对日本一家人寿保险公司签发的160多万份自动续期定期人寿保险合同的微观数据分析显示，由于医疗和其他选择，自动续期定期人寿保险（续期前）既不能识别逆向选择问题，也不能识别道德风险问题。然而，在更新后的10年里，逆向选择和道德风险确实发生了。考虑到价格竞争的加剧，为了公平分配投保人的财务负担，也为了生命保险公司的财务健全性，有必要对定期人寿保险自动续保进行研究。
