We've reviewed 5,067 cases of claims by death that had occured for about 5 years from January, 1979 to October, 1983. As a result, We came to following conclusions; First, the greater part of deaths above mentioned were due to the Disease of Adult such as the Malignant neoplasm(18.4%), a Heart disease(10.4%), Liver cirrhosis(9.1%) and the Cerebrovascular disease(7.6%) as well as Accidental Death(26.5%), which were occupied by 72% of the whole. Second, classifying them by medical examination or non-medical, deaths in case of non-medical examination showed 80.8% of the. whole. And for age, sections ranging from 40 to 49 and from 30 to 39 took the overwhelming portions by 36.9% and 29.8% respectively, both of which showed 66.7% of the whole. Third, for the period elapsed, deaths within 1 year from the entrance showed 21.3% and that from 1 years to under 2 years, 19.9%. Thus the rate of early death under 2 years stood for 41.2% of the whole. Fourth, for occupation of the insureds, commerce occupied 20.4%, company employees 14.4%, agriculture 13.3%. These three categories marked 48.8% of the whole. From this, it appeared that the accidental death rate of the insured with the risky occupation was much greater than orthers.

본 논문은 우리나라 생명보험산업의 장수리스크에 대한 자연헤지가 충분히 이루어지고 있는가를 평가해 보았다. 연금보험과 종신보험 준비금 계산 시 사망률 모형으로는 Lee-Carter 모형을 적용하였다. 사망률 개선 시나리오로는 연금보험과 종신보험 사망률이 모두 10%와 20% 개선되는 경우, 50세 이하 저연령 사망률은 10% 개선되고, 50세 이상 고연령 사망률은 20% 개선되는 경우, 마지막으로 연금보험 사망률은 20% 개선되지만 종신보험 사망률은 10% 개선되는 등 네 가지 시나리오를 살펴보았다. 분석결과 연금보험과 종신보험에 동일한 사망률 충격을 가하는 경우와 고연령의 사망률 개선이 저연령에 비해 빠르게 나타나는 경우 모두 연금보험과 종신보험 준비금의 합은 감소하는 것으로 나타났다. 네 번째 시나리오에서만 전체 준비금은 증가하였으나, 이 경우에도 연금보험 준비금 증가의 60% 이상이 자연헤지에 의해 상쇄하는 것으로 나타났다. 따라서 우리나라 생명보험산업의 장수리스크는 자연헤지를 통해 충분히 관리되고 있다고 판단된다.

생명보험의 보험료는 보험가입자들의 예정 수명분포와 예정 이자율에 기초하여 산출되게 된다. 산출된 보험료는 향후 해당 보험을 운영하는 과정에서 발생할 수 있는 보험회사나 보험가입자들의 손실 그리고 이들이 부담하는 리스크에 직접적인 영향을 미치게 된다. 따라서 생명 보험에서 이들 두 가지 요소, 즉 예정 수명분포와 예정 이자율은 중요한 영향 변수로 여겨진다. 본 논문에서는 종신보험에서 이들 영향 변수가 보험료, 보험 운영상의 리스크, 보험운영에 있어서의 손실 확률에 미치는 영향력을 분석하고 상대적인 영향력의 크기를 비교해 보고자 한다.

Internally Korean insurance market is that whole life products' growth are becoming slowdown that's why new insurance products have appeared on the market in consideration of consumer's needs recently. Externally domestic insurance market competitions has drifted from insurance industry to whole financial industry since bankasurance started. Life insurance companies should open up a new market to survive from severe competitions. Worksite marketing can be an alternative. An insurer make arrangements with an employer about an insurance terms which an insurer offers in Worksite marketing. Then eligible individuals enroll in the plans at their own discretion and pay 100 percent of the premium for coverage through payroll deductions. An employer doesn't need to pay extra money for additional benefit but can raise employee's loyalty and satisfaction of company through worksite marketing. An employee can be covered at discounted premium rate and less strict underwriting guidelines to an insurer compared to individual insurance. In developed countries specially U.S insurance market, Worksite marketing is getting very popular and growing rapidly due to the advantages. Worksite marketing has both individual insurance characters and group insurance characters. Individual insurance characters are that employees enroll in the plans at their own discretion and pay 100 percent of the premium for coverage. Group insurance characters are that actively at work and participation etc. An insurer have to reflect these two characters on Worksite marketing when an insurance company work out a plan for developing products and underwriting guidelines. When an insurer devise worksite products, one should consider participation level which means percentage of eligible employees participating. Participation is related to anti-selection. As we know underwriting is essential for every kind of insurance, especially underwriting plays major role in worksite marketing. We can see that in the below. Firstly, it has a function in calculation of premium rate. When calculate premium rate for worksite products underwriters have to estimate expected participation level and risk factors. So underwriters and acturies keep in close contact with each other. Secondly, underwriting methods are important. When an insurer underwrite worksite products, there are three kinds of underwriting methods. These are Simplified issue underwriting, Full underwriting and Guaranteed issue underwriting. Simplified issue underwriting typically requires no medical examination, but usually requires supplying satisfactory answers to one or several health and/or lifestyle questions. Full underwriting requires a complete medical history questionnaire that may further require an exam. Guaranteed issue underwriting means that coverage is issued without the employee having to provide evidence of insurability. When insurer set the GI limit are usually based on the type of industry, number of eligible employees, the average amount of coverage and participation level. In addition to insurer should have a clear definition of eligible employee on the insurance provision and application form. It will minimize possibility of trouble claims and anti-selection. An insurer also establish preexisting condition exclusion and special guidelines for late entrants. When an insurer introduce Worksite marketing to Korean insurance market, an insurer has to examine market research to analyze potential market and strategy of sales most of all. Also an insurer should review real situation of the U.S, England and Japanese market etc. There are a lot of new technologies about worksite marketing process that an insurer should learn. When an insurer consider many things which we explained it can be a real alternative.

In the shortest period of time, we achieved both industrialization and democratization. We also achieved good performance in health care sector. Whole population are covered by health insurance since 1989 and health outcomes, such as infant mortality, life expectance show good level. However, health care system has several problems, rapidly increasing rate of health care expenditure, dissatisfaction of both consumers and suppliers. Current health care system does not reconcile with market competition principle. Causes of these problems originated from 1977 paradigm which was formed to expand health insurance to whole population within short period. Dominant assumption of 1977 paradigm is to assure equitable access of health care by government's command and control. We urgently demand to reform the 1977 paradigm to suitable in 21th century. Our economy entered into a road to advancement. We have concerns how President Lee's administration reform health care system to harmonize with economic development and to achieve advancement in health care sector.

Parental leave in Sweden is a part of the health insurance in national social insurance system. It has two kinds of benefits. One is parental cash benefit paid for both husband and wife on the occasion of child birth, currently 450days for each child. The other is temporary parental cash benefit when a child under the age of twelve or a caretaker for him is illness, which is six months for a child a year. Parental insurance in Sweden permits parents to take care of their children just after birth at home with the amount of 80% of monthly income for 360 days and 60 Swedish krone each day for 90 days more. It also permits parents with children under the age of eight of part-time work and return to former job at full-time base when they want. It consequently entourage women's economic activity in her whole life and contributes to promotion of equality in sex roles between husband and wife. This insurance scheme is beneficient in that it enhances individual and family welfare and also secures labour force. This case study on Swedish parental insurance offers implication how to resolve the conflict between women's increased demand for economic activity and maternal role.

Over the past decades, the Lee-Carter model [1] has attracted much attention from various demography-related fields in order to project the future mortality rates. In the Lee-Carter model, the speed of mortality improvement is stochastically modeled by the so-called mortality index and is used to forecast the future mortality rates based on the time series analysis. However, the modeling is applied to long time series and thus an important structural change might exist, leading to potentially large long-term forecasting errors. Therefore, in this paper, we are interested in detecting the structural change of the Lee-Carter model and investigating the actuarial implications. For the purpose, we employ the tests proposed by Coelho and Nunes [2] and analyze the mortality data for six countries including Korea since 1970. Also, we calculate life expectancies and whole life insurance premiums by taking into account the structural change found in the Korean male mortality rates. Our empirical result shows that more caution needs to be paid to the Lee-Carter modeling and its actuarial applications.
