dc.description.abstractIn this paper, we examine the premiums and risks for whole life insurance and joint life insurance based on the parametric models, which are generally used in the industry of life insurance. Particularly, it is common that the death of a spouse has a significant impact on the conditional survival probability of the last surviving spouse. In this sense, this study examines joint life insurance and joint life annuity by assuming such dependence in a married couple’s lifetime. First, we calculate the premiums and risks in joint life insurance and joint life annuity by applying the bivariate distributions based on the likelihood ratio order. Furthermore, we study the effect of change of the parameter representing dependence on premiums and risks.;한 사람의 사망은 남은 가족의 수명에 영향을 준다. 따라서, 연생보험의 보험료를 산출하기 위해서 보험가입자 간의 수명에 연관성을 반영하는 것이 중요하다. 이에 따라, 보험가입자의 상호의존적인 수명분포를 모형화하는 많은 연구가 진행되어 왔다. 본 논문에서는 likelihood ratio order에 기반한 이변량 분포를 적용하여 부부 사이의 상호의존적 수명분포를 모형화 한다. 제안된 모형을 통해, 연생보험 및 연생연금에 대한 부부의 가입연령별 보험료와 리스크를 산출한다. 또한, likelihood ratio order의 모수를 변화시키며 상호의존성의 크기에 따른 보험료와 리스크의 변화를 확인한다.-
