Abstract

Calculating or estimating the proper insurance premium is very important decision making process for both the policyholder and the insurance company. The credibility theory is one of the most important theories in actuarial science to get the proper premium. In this research, we introduce the rule of relative exposure volume, the square root rule and the B$\ddot{u}$hlmann credibility, and estimate the new premiums based on these methods. By real data analysis, the accuracy of these credibility methods are compared.

적정한 보험료의 산출은 보험가입자는 물론 보험회사에게도 매우 중요한 의사결정이라고 할 수 있다. 보험통계학의 중요 이론 중 하나인 신뢰도이론은 손해보험분야에서 적정보험료의 산출에 중요하게 사용되는 이론이다. 본 논문에서는 유효대수 법칙, 제곱근법칙, B$\ddot{u}$hlmann 신뢰도의 계산방법과 그 의미를 살펴보고, 각 방법에 따라 도출된 신뢰도를 바탕으로 산출한 적정보험료의 예측치와 실제 손해발생액의 차이를 비교하였다. 국내 손해보험사의 자동차보험에 대한 실제 데이터를 사용하여 각 신뢰도에 따라 산출된 보험료를 비교분석한 결과, 심도를 고려하지 않은 제곱근 법칙에 근거하여 구한 부분신뢰도가 가장 정확하게 보험금을 추정하였다.
