Little is known about unemployment duration and re-employment pattern. This paper empirically examines unemployment duration and re-employment pattern using data by the 1998 national survey about the unemployed and their needs. A parametric survival model(Weibull model) is adopted to identify variables predicting unemployment duration. It is found that the data including people without unemployment insurance as well as people with unemployment insurance fit the Weibull model including the hazard distribution that the hazard of reemployment is increasing at an decreasing rate. Variables that affect unemployment duration are age, householdership, family income, size of prior employment organization, and cause of unemployment. In re-employment pattern, statistically significant variables are age, type of prior employment industry, prior employment pattern, and membership in unemployment insurance. This paper provides a basic knowledge about realities of unemployed individuals in the economic crisis period of Korea, identifies research areas for further research, and develops policy implications for the unemployed.

In this paper, we explore the effects of export insurance on the Korea's export by using the gravity model with the data of 112 countries that Korea exports on years of 2005 and 2009. For this model, we used the Korea export as a dependent variables and real GDP, distance between the two nations, export insurance, country credit rating of the Korea's counterpart countries and FTA were used as an independent variables. The results show that the underwriting performance of the export insurance and the sovereign credit rating of the export counterpart countries have the positive impact on Korea's export. Also, the impact of the export insurance is more increasing to the Korea exportation but the importance of the economy size of the export counterpart countries decreased after 2008 global financial crisis. Particularly, the influence to the export by the sovereign credit rating has diminished in that period and this seems to be due to the export insurance has increased. These results imply that the export insurance plays an important role to promote the Korea's exportation since 2008 global recession. Especially, if the recession continues, then there will be more crippling impact to the small-mid size companies rather than large size companies. Therefore, Korea government should do their best to continuously expand the export insurance for the purpose of increasing Korea exportation, expecially to the small-mid size companies.

현행 사학연금법은 공무원연금법 제46조 제1항 제4호 "정원 감소로 퇴직한 때부터 연금 지급" 조항을 준용함에 따라 정원감축 및 폐교에 따른 퇴직을 할 경우 법에 명시된 연금지급 개시연령이 아닌 퇴직 후 5년 이후에 조기연금을 지급하도록 하고 있다. 본 연구의 목적은 현행 지급개시연령 규정의 타당성을 검토하고 개선방안을 제시하는데 있다. 이를 위해 사학연금 지급개시연령 현황 및 사립학교 폐교 현황과 사학연금이 공무원연금법을 준용함으로써 발생하는 문제점 및 현행 규정에 따른 연금지급 시 사학연금재정에 미치는 영향을 분석하고 법 개정의 타당성을 검토하여 개선방안을 모색하였다. 주요 연구결과는 다음과 같다. 65세 정년이 되어 은퇴하지 않고 중도에 퇴직하거나 고용이 취소되어 지급개시연령 보다 훨씬 일찍 조기연금을 지급하게 될 경우에는 퇴직연금 자체가 노후소득보장제도이기 보다는 실업급여의 성격으로 전락하게 되는 측면이 있다. 또한, 폐교에 재직 중인 교직원은 근로가 가능한 연령과 건강상태임에도 불구하고 즉시 연금을 수급하게 됨으로써 재취업을 하지 않을 경우 연금에 대한 의존성이 높아지고 근로유인을 저해할 수 있다. 그리고 최근 잦은 폐교로 인한 연금수급자 과다 발생 및 재정적 지속가능성의 문제가 있다. 또한 사학연금 가입자와 공무원연금 가입자의 특성을 비교하면 중요한 차이점이 발견된다. 국공립학교의 경우에는 해당 학교가 폐교 또는 정원이 감소될 경우 다른 지역 학교로 해당 재직 교직원을 이동 배치하는 등의 대처 방안을 시행하기 때문에 사실상 퇴직하는 사례가 거의 없는 반면, 사학연금 가입자의 경우 공무원연금 가입자에 비해 상대적으로 고용불안에 노출되어 있고, 학령인구 감소 등으로 인해 사립학교 폐교 가능성이 상존하므로 이들에 대한 생활안정대책이 필요하다. 또한 공무원 조직의 개폐 및 정원 감소는 법령으로 정하고 있지만, 사립학교 교직원의 개폐 및 정원의 감소는 사학기관의 특성에 따라 차이가 있다. 그리고 공무원의 경우 공무원연금의 대상이면서도 고용형태의 상대적 취약점을 감안하여 임기제 공무원의 경우 고용보험의 가입이 일부 허용되나, 사학연금 가입자의 경우에는 전면적으로 가입이 제한되어 직역연금 간 형평성 문제가 발생하고 있다. 그리고 국민연금과 비교할 때 다음과 같은 차이점이 있다. 국민연금법의 경우 사업장가입자로 적용받고 있다 하더라도 준용법과 같은 사립학교 폐교 시 조기연금 수급 규정이 없으며, 고용보험법의 적용으로 실직 시 실업급여 등의 대응책이 있긴 하나 연금 수급을 통한 소득보장 수준에는 못 미치는 제도적 보완책을 갖추고 있다. 또한, 국민연금 가입자는 고용보험에 적용되나, 사학연금 가입자는 실업상태에 놓였을 경우 고용보험의 적용을 받지 못한다는 점에서 차이가 존재한다. 이에 다음과 같은 개선방안을 제시하였다. 폐교 시 사학연금 가입자의 생활안정을 위해 고용보험 가입을 검토할 필요가 있고, 재정안정화를 위해 연금을 전액지급하기 보다는 퇴직일부터 지급개시연령까지의 잔여기간에 따라 차등지급하는 방안을 모색해 볼 수 있으며, 고용보험법상의 실업급여 제도를 원용하고 소정의 연금지급기간을 설정하여 연금을 지급하는 방안을 고려할 필요가 있다. 이에 더하여 사학연금제도 내에서 별도의 고용보험기금을 마련하는 방안도 모색해볼 필요가 있다.

In accordance with the new healthcare policy of government (Moon Jae-In Care) to strengthen health insurance coverage, the National Health Insurance (NHI) coverage of brain magnetic resonance imaging (MRI), brain/neck MR angiography (MRA), and head and neck MRI have been expanded since 2018 in Korea. This article has been reviewed focusing on the "Detailed matter concerning criteria and method for providing reimbursed services in the NHI. Some revisions" regarding reimbursement for MRI, which was revised from October 2018 to April 2020 and is currently in effect. It included the MRI reimbursement system in Korea, recent adjustment of the reimbursement coverage for patients with headache or dizziness, and reimbursement coverage, standard imaging, and radiologic report of brain MRI, brain/neck MRA and head and neck MRI. This article could help radiologists gain knowledge on health insurance to protect the expertise of the radiologist and to play a leading role in the hospital. As the policy changes, detailed matter concerning criteria and method for providing reimbursed services in the NHI may be revised. Therefore, radiologists should update issues related to insurance reimbursement for MRI continuously.

As Chinese insurance market grows rapidly due to market reforms, China got recognition as second-largest insurance market in the world in 2016. However Korean insurance companies have had difficulties to grow in Chinese insurance market despite Chinese participation in the World Trade Organization (WTO) and the growth of chinese insurance market. The reason for the decline in Korean insurance companies is economic retaliation due to the deployment of THAAD in Korea. However, this is not a fundamental reason. The underlying cause of the effects of economic retaliation is the result of insufficient negotiations in Korea-China FTA services sector. In Service sector of Korea-China FTA, the level of concession between Korea and China differs greatly, when comparing China and South Korea's FTA. In addition, it has only been a few years since China collected the position of the WTO Doha Agenda, which currently deals with concessions on intellectual property rights and services. More important is that the Korea-China FTA service sector, as it stopped short of being protected by the most-favored-nation state treatment level when Korean insurance companies entered China. Further negotiations to supplement the weak points in the Korea-China FTA service sector were promised in December 2017, but international tensions over THAAD deployment made it impossible to hold such negotiations. However, due to changes in international affairs in 2018, the first additional negotiation was decided and held. This paper implicates strategies of further negotiation between Korea and China for service and investment chapter. Consequently, the aim of this paper suggests directions how to re-enter Chinese insurance market to Korean insurance companies.

This study used Gauss-Poisson jump diffusion process on standard assets to estimate the statutory reserves of Variable Annuity (VA) guarantees specified in Korean bylaw of insurance supervision and calculated guarantee fees and risks based on the model to see the effect of considering the jumps. Financial assets, except KOSPI 200, have fat-tailed return distributions, which is an indirect evidence of discontinuous jumps. In the case of a domestic stock index and foreign stock indexes(Korean Won), guarantee fees and risks decrease when jumps are considered in models of underlying assets. This is explained by decreases in standard deviations after the jump diffusion is considered. On the other hand, in the case of domestic bond indexes and a foreign bond index(Korean Won), guarantee fees and risks tend to increase when jumps are considered. Results from a foreign stock index(US Dollar) and a foreign bond index(US Dollar) were opposite to those from the same kinds of Korean Won indexes. We conclude that VA guarantee fees and risks may be under or over estimated when jumps are not considered in models of underlying assets.

This paper investigates the cyclical behavior of UI benefit take-up rate, the share of unemployed persons who are eligible for job seekers' allowances(JSA) and actually receive them. Using Korea's Employment Insurance DB, it also identifies the factors linked to the decision to take up job seekers' allowances. The results show that the take-up rate is countercyclical and leads both unemployment rate and Coincident Composite Index cyclical component by 6 months and is positively correlated with replacement rate and benefit duration, suggesting that extending benefit duration and raising benefit level can boost benefit claims to increase take-up rates in Korea.

This study utilizes raw data from "Research on the actual condition of firms' information security" of KISA (2010) and constructs panel dataset to analyze a causal relationship between information security investment and security breach. Using Difference in Difference estimation method we find the following results. First, while the usual causality that information security investment reduces security breach is not supported, the reverse causality that security breach increases information security investment is well explained. Second, contrary to the conventional wisdom, firms in the finance/insurance business sector show the most significant reverse causality pattern.

It is the law that injured workers must be paid compensation through occupational health and safety insurance. But sometimes, construction companies cover the compensation for an accident by themselves in order to conceal the fact of an accident. The reason for this concealment is that they wish to get a high mark in PQ. From the point of view of a subcontractor, another reason is to avoid any negative consequences in bids. According to interviewees, some workers, knowing the vulnerability of their employers in this area, demand unreasonable levels of compensation. This study examined the circumstances, influences and participants' perception of accidents on construction sites.

본 연구는 우리나라 상장기업중 금융 보험업을 제외하고 비교적 상장기업수가 많은 9개 산업에서 임의로 선정한 180개 표본기업을 분석대상으로 하였다. 1989년 1월부터 1996년 12월까지를 분석대상기간으로 설정하여 베타계수 예측능력을 향상시키기 위한 회계위험변수모형의 예측능력을 평가하고 위험수준별 예측능력에 차이가 있는지도 분석하였다. 아울러 베타계수 추정시 사용된 수익률 측정간격에 빠른 베타계수의 안정성과 회계위험변수모형의 예측능력을 분식하였다. 본 연구의 중요한 결과를 요약하면 다음과 같다. 첫째, 포트폴리오를 구성한 경우 수익률 측정기간에 관계없이 일관되게 예측오차가 유의적으로 적게 나타나 회계위험변수모형의 베타계수 예측능력이 우수하였으며 베타계수예측에 회계 변수의 유용성이 확인되었다. 둘째, 위험수준에 따른 베타계수의 안정성 분석에서는 중위험집단의 베타가 안정성이 높았으며 고위험집단에서 예측오차가 가장 크게 나타나 불안정하였다. 회계위험변수모형의 예측능력은 위험수준에 관계없이 단순모형보다 우수하여 베타예측에 회계정보의 유용성을 일반화시킬 수 있을 것이다. 셋째, 수익률 측정간격에 따른 베타계수의 안정성과 예측능력 분석에서는 월별수익률을 이용하는 경우보다 주별수익률을 이용하는 경우 추정베타의 안정성이 높고 베타계수 예측모형의 예측능력이 향상되는 것으로 나타났다. 넷째, OLS베타를 수정하지 않고 이용하는 경우보다 Bayesian 기법으로 수정한 Bayesian수정 베타를 이용할 경우 예측오차가 감소하여 Bayesian 수정기법의 유용성이 확인되었다.
