While the local health insurance and the employment-based insurance were integrated in July 2000, the insured is divided into employment-based insured and the local insured and the relevant premium has been applied to both groups. The health insurance premium having the feature of social solidarity has to be determined depending on income, that is, the ability to pay in accordance with the principles of social insurance. While employment-based insurance premium has been determined depending on the earned income, the local insurance premium for the local insured has been determined by scoring gross income(evaluated income), property and possession of automobiles. A variety of improvement approaches has been implemented including introduction of the employment-based insurance premium ceiling system (2002) and the change of property scoring system for the local insured (2006). However, the health insurance system which was merged in 2000 has been implemented up to now without significant change even though there were lots of socio-demographic change including increase of income level and the population structure such as low birth and aging. In other words, it is required to implement the premium rating system securing the income-based equity. Nevertheless, it was inevitable to apply the diverse rating standards in the early stage because it was very difficult to verify the income of the self-employed. Although the income verification rate was significantly increased from 23% in 1989 to 44% in 2010, the irrational standards including property, automobiles, living standard and activity rate have been still applied to the local insured because it is difficult to secure the validity of insurance premium rating system and it severely lacks of security. This paper investigated whether the current insurance premium rating system for the local insured imposing the premium on the basis of 'gender' and 'age' complies with the basic human rights secured by the current Constitution of the Republic of Korea with respect to the practical and theoretic irrationality of insurance premium rating system and standards for he local insured. In accordance with the analysis results, this paper proposed the approach to improve the system.

Background: This study aims to examine the regressiveness of national health insurance (NHI) premium burdens for local subscribers. The government has established a restructuring of health insurance contributions in 2017. Therefore, insurance premium reform began in 2018 and the second national health insurance premium reform will be carried out in 2022. We will analyze local subscribers before and after the policy reform of 2018. Methods: This study used data from 'local premium imposition elements' in the health insurance statistics annual reports (2017-2019) on National Health Insurance Service (NHIS). This study was calculated contribution rates according to levels of income and property for local insured by the method of comparing. Simulations of primary and secondary reforms were conducted in the study to determine regressiveness. Results: Insurance premiums for local subscribers were analyzed separately by income and property insurance premiums. In the income premium analysis, the higher the income, the lower the premium rate, and then the fixed rate was maintained from a certain section. The regressiveness of income insurance premiums has been eased in part. On the other hand, the property insurance premium burden was found to be regressive still by income class. Conclusion: Regressiveness analysis showed that a decrease in income contributions was achieved to local insured in the first phase of reform. But in the second phase of reform, more consideration should be given to reductions of property premium portions of local subscribers. Based on the results, the author suggested policy discussions to reorganizing the new systems of NHI contribution of local Insured.

This study examined market size of private health insurance premium and individual characteristics associated with the market size change in Korea, using wave 1 (2008) and wave 2 (2009) of Korea Health Panel. The market size was 24.4 trillion Korean won in 2008 and 26.9 trillion in 2009. The increase rate of private health insurance premium among those who were the elderly, single, or the poor was higher than that among their counterpart respectively. Health status and utilization were insignificant in determining the increase rate of private health insurance premium. These findings were more obvious among the uninsured in 2008 than among the insured in 2008. The increase of private health insurance premium in Korea imply the increase of willingness-to-pay for health risk through private sector. The authors suggest policy intervention for accessability to health care for the underprivileged and weak through enlargement of Korean social health insurance benefit.

예금보험료는 각 금융기관의 위험정도에 상응해서 부과되어야 하지만 우리나라는 현재 금융 업종별로만 차등화되어 있고 같은 업종 금융기관간에는 동일 예금보험료율이 적용되고 있다. 고정예금 보험료율 부과방식에 비하여 변동예금 보험료율 부과방식은 논리적 타당성을 지니고 있지만 실제 적용가능한 객관적이고 측정이 용이한 기준마련이 어렵다. 본 연구에서는 옵션평가모형(option pricing model)을 이용하여 1995년부터 2001년까지 개별금융기관 및 전체 금융업종별로 예금보험료율을 추정하고 분석하였다. 금융업종별로 상호비교한 다음 연도별 추세분석과 분포분석을 하였다. 다음으로 추정 예금보험료율과 은행의 자본적정성, 수익성 및 자산건전성을 나타내는 관련 변수들과의 상관관계를 분석하였다. 연구 결과 개별 금융기관에 따라, 그리고 금융업종 및 표본기간에 따라 예금보험료율의 추정치가 상당한 차이를 보였다. 이는 금융업종에 따라 예금보험료율을 차등부과하고 개별은행의 위험을 반영하는 위험반영 차등 예금보험료율 제도의 타당성을 뒷받침한다고 할 수 있다. 은행보고자료와 감독기관의 검사자료가 지니고 있는 주관적 요소라는 단점을 극복하는 자료인 시장자료를 이용하는 본 연구의 추정결과는 예금보험료 부과에 보완적으로 사용할 수 있을 것이다.

This paper aims to find a reasonable solvency margin system in non-life insurance industry and also to evaluate the appropriateness of the current solvency margin regulation system in Korea. The current solvency margin system in Korea, based on EU's solvency margin model, was introduced during the 1997 financial crisis. The solvency requirement is not based on non-life insurer's risk, but simply on written premiums. The current solvency margin for general insurance, such as fire, marine, and automobile insurance, is determined by the greater between a premium-based amount and a claim-based amount, where the premium-based solvency margin is calculated by multiplying the net written premium for the preceding year by the premium based solvency margin ratio. Also, the amount of solvency margin for long term insurance is set at 4% of the policy reserve of the long term insurance. Still, there exist many differences between the current solvency margin regulation system in Korea and EU's model. This paper focuses on the rationality of the solvency margin regulation system, and compares the current system in Korea with EU's model and the RBC(Risk Based Capital) system in U.S. and Japan. Finally, this paper suggests a more specific and reasonable solvency margin system to be developed in Korea.

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.
