Abstract

This research used the contents of the contracts and policies of xx insurance company (Data from Jan 1, 2011 to Dec 31, 2016) in order to understand the factors leading to a long-term contract which makes up an important part of the life insurance industry in Korea. This research used the Cox's proportional hazards (PH) model and penalized variable selection methods to look for variables that led to a long-term contract. Variables considered include the change of advisor, sex, disease status (anamnesis), risk of job, subscription types, investment patterns of variable insurance, personal versus corporate contracts and driving status, etc. The most significant factor was the advisor (in case where the recruiter and the collector were different) status, whether it has been changed or not. The second most important factor was the reward type 2 (annuity insurance). Then, the variable insurance investment tendency 4 (safety-pursuing type), and 5 (risk-aversion type) affected the outcome respectively. This research explores the ways in which the life insurance industry can prolong the contracts, the new market for it, the necessity of the advisors’ long-term commitment, the program consulting, and the improvement of the investment aspects.
