To investigate the interdependence of the decisions on when to retire and how much consume before and after retirement, we compare the pre- (or post-) retirement consumption conditioned on the retirement decision with pre- (or post-) retirement consumption regardless of retirement decision by using the Korea Labor and Income Panel Study(KLIPS). We employ the two-stage switching regression for the econometric method to investigate the interdependence of two decisions of retirement and pre- or post retirement consumption. Then we test the existence of the interdependence in terms of the significance of the estimated selection biases which appear in the pre- (post-) retirement consumption equations for early and late retirees. In those equations, we also compare the income elasticity of the consumption of the early retirees with that of the late retirees. The empirical results show that there is negative selection bias in early retirees' consumption. These results imply that due to the early retirement decision early retirees would have consumed less than they actually have. The income elasticities of the consumption of the early retirees is smaller than that of the late retirees in pre- (or post-) retirement consumption equation. This result shows that relatively longer retirement period due 10 the early retirement affect the pre-retirement consumption. early retirees' marginal propensity to consume should be lower than that of the late retirees.

The purpose of this paper is to reduce the reverse-causality and overestimate bias of analysis on how health affected middle-aged and elderly worker's early retirement. From the Korean Longitudinal Study of Ageing(KLoSA) panel data, I researched 1,049 people who were 45-52 years old in 2006. To eliminate the reverse-causality problem, I used the health data which is surveyed before retirement. To reduce bias, I controlled the health status when retirees worked. The main results are as follows. First, the worsened health still affects the hazard of early retirement, with reducing the endogeneity problem. Second, chronic illness is one of the strong predictors of early retirement to self-employed, and self-reported bad health is the main health predictor of wage workers. These results give two implications; first, the impact magnitude of the health indicator depends on employment type. Each employment type has different flexibility of working hours. It seems that the flexibility can reduce early retirement hazard with health problems. Self-employed, who has more flexibility of working hours can work until they have to stop working due to the serious health problem or doctor's advice. Second, to promote middle-aged and elderly workers to keep working, the long-term health policy which decreases chronic illness is needed.

사회보험(Social Insurance)은 노령(老齡) 등 미래(未來)에 확실(確實)히 발생(發生)할 사안(事案)뿐 아니라 질병 등 불확실(不確實)한 사안(事案)에 의한 소득(所得)의 상실(喪失)을 보상하기 위한 보험(保險)의 역할을 한다. 대부분의 사회보험연구는 이 불확실성(不確實性)이 배제된 모형의 분석을 하고 있는데 본고(本稿)에서는 그러한 불확실성(不確實性)이 존재(存在)할 때 사회보험이 개인의 은퇴시기 결정에 미치는 영향을 분석하였다. 사회보험은 노동기(勞動期)로부터 은퇴기(隱退期)로의 소득이전(所得移轉)일 뿐 아니라 일을 할 수 있는 상태로부터 질병 등의 불확실한 사안(事案)에 의해 초래된, 일을 할 수 없는 상태로의 소득이전(所得移轉)도 된다. 이 두 번째의 역할 때문에 사회보험은 개인(個人)의 은퇴시기(隱退時期)를 늦추는 효과를 보일 수 있다. 특히 사회적 최선적정은퇴시기(最善適正隱退時期)(first best optimum)는 사회보험이 전혀 없는 경우의 은퇴시기가 보다 늦다. 반면 어느 일정(一定)한 시점(時點) 이후에만 사회보험(社會保險)의 수혜(受惠)가 가능(可能)하다면 이는 오히려 조기은퇴(早期隱退)를 초래(招來)하게 된다는 것을 보였다.

본 연구는 은퇴 후 신체적 건강이 시간이 지남에 따라 어떤 변화양상을 나타내는지, 은퇴 후 신체적 건강에 영향을 주는 것으로 알려진 은퇴 특성(은퇴시점, 은퇴자발성 여부) 변인이 은퇴 후 신체적 건강의 궤적에 어떠한 영향을 미치는지를 분석하고자 하는 목적으로 실시되었다. 분석 자료는 국민노후보장패널 3차시(2009년), 4차시(2011년), 5차시(2013년) 종단자료이며, 2,857명을 대상으로 잠재성장모형 분석을 실시하였다. 연구결과, 첫째, 중 고령은퇴자의 신체적 건강은 시간의 흐름의 변화를 알아보기 위해 무조건부 모형을 통해 확인한 결과, 중 고령은퇴자들은 시간이 지남에 따라 더 높은 수준의 ADL 값을 갖는 것으로 나타났다. 둘째, 중 고령은퇴자의 신체적 건강변화와 관련이 있는 은퇴특성은 무엇인지 조건부 모형을 통해 알아본 결과, 은퇴 특성 변수로는 조기은퇴자일 때, 은퇴가 비자발적일 때, 건강상 이유로 은퇴했을 때 더 높은 ADL 초기값을 보였다. 또한 변화궤적 영향요인을 살펴본 결과, 은퇴특성에서는 어떤 변수도 유의성을 보이지 않았고, 인구사회학적 변수 중에서는 연령이 높을수록, 소득이 높을수록 ADL의 증가속도가 더욱 가파른 것으로 나타났다.

This study analyzed plans for retirement by focusing on preferred retirement timing(PRT) measure. Current pension program show rather strong guideline about the timing of full-retirement. This study asked whether the middle age group are willing to retire correspond to the policy guidelines or not. Research sample came from 2008 KLOSA data, recruiting 1,367 workers who are residing in cities or in metropolitan area (women: 34.8%). I have analyzed one item question asking "In what age do you want to fully retire?", The results showed that, about two third of respondents declared they do not want to retire unless they have health problems, or would expect to retire no earlier than age 70. However, a third of respondents expected normal retirement coming between 60~64. Second, the determinants of timing for retirement were differ by PRT. Social determinants, such as gender, short work hours, being employed, and higher status in family income were associated with early PRT. While, good health status, positive view on the future economics were highly associated with late PRT. The results reveal that the timing of retirement is getting more diverse and obscure in the individual level.

Using the first wave of KLoSA(Korean Longitudinal Study of Ageing) beta version, this study analyzed factors affecting early retired men's subjective life satisfaction through Binary Logit and Multiple Regression. Total 552 men were selected as a sample. The main results of empirical analysis in this study were as follows: The retirement reason(health-) and monthly household income(+) affected whether they were satisfied with the retirement life or not and subjective life satisfaction over all. Especially, the retirement reason(health-) had a stronger effect on whether early retired min were satisfied with the retirement life or not and their subjective life satisfaction than monthly household income revealed significant variable in previous studies. This result represents that the retiree's life satisfaction analysis model must include retiree's characteristics at the time of retirement as well as retiree's current status characteristics or socio-economic characteristics.

This study aims to inform seafarers to prepare their retired life by researching the life style of ex-seafarers. These information will also help seafarers to increase job satisfaction and government to establish national policy. 217 retirees who have several educational background responded the research questionnaire. Research results are as follows; First, Korean seafarers' retired ages are faster than shore employee due to the isolation from their families and society. Second, life satisfaction of retired seafarers depends on the level of life expenses regardless the educational background or length of sea life. Third, the level of retired life expenses of shore based, higher education background or short sea-life seafarers is higher than the sea based, lower education background or long sea-life seafarers. Forth, life style of retired seafarers is staying at home regardless their expectation during career period. Finally special seafarers' social security is needed and education to the ex-seafarers will help re-enter for sea-life.

산업 패러다임과 트랜드의 변화 속에서도 저성장, 고령화는 뉴 노말 시대의 가장 큰 문제점으로 대두되고 있다. 이에 따라 각자도생이 필요하며, 결국 창업이 대세인 시대가 되었다. 성공적인 창업을 위해서는 많은 준비와 실패 노하우의 축적이 필요하나 실패를 용납하지 않는 우리 사회분위기상 이는 쉽지 않다. 조사에 따르면 창업 장애요인으로 '창업실패 및 재기에 대한 두려움', '창업 준비부터 성공까지의 생계유지'가 많은 부분을 차지하고 있다. 이러한 장애요인을 줄이는 방법으로 Hybrid창업을 제시할 수 있으나 국내 많은 기업이 직장인의 겸직을 제한하는 탓에 Hybrid창업이 활성화되지 못하고 있고 관련 연구도 거의 없는 수준이다. 그러나 52시간 근무제로 직장인이 투잡(two-job)을 통한 수익창출 기회는 증가하였고, 고용불안과 은퇴이후를 고민하는 직장인들이 우회 창업하는 경우도 적지 않다. 이러한 Hybrid창업 현상은 조기은퇴, 고령화의 영향으로 계속 증가할 것으로 예상됨에 따라 관련 연구를 축적할 필요가 있다. 본 연구의 목적은 직장인의 Hybrid 창업의도에 미치는 영향요인을 탐색하는데 있다. 본 연구에서는 직장인의 창업가 특성, 창업역량, 경력지향성과 Hybrid창업의도간의 관계와, 직장인의 조직불안 인식의 조절효과를 검증하고자 한다.

This paper deals with financing an early retirement scheme problem(FERSP) with minimum initial cash and filling up maximum financial interest. For this problem, Guéret et al. programming the Mosel, and Edvall merely realize the CPLEX Branch-and-Cut MIP Solver program to get the optimal solution. But there is no clear rule to finding the solution. This paper suggests calculation formula of bond number decision-making that the reverse from long arrival due date to short. Then we optimize and confirm the bonds number in accordance with continuative effect of the arrival due date. The shortage prepare with the principal and interest of one year deposit(saving) reversely calculation formula.

The aim of this paper is to describe a long-term trend toward earlier retirement and its reversal since 1985 in the United States, together with changes in socioeconomic conditions and social-policy programs which have contributed to this new development. The American people's recent propensity to retire at relatively younger ages was mainly a result of secular increase in individual wealth that had made it possible for them to enjoy higher standard of living without their participation in labor market activities at older ages. In addition to the introduction of compulsory retirement system, both social security retirement pension program and corporate pension system have also contributed significantly to the declining retirement age and its reversal around the mid-1980s. This paper pays full attention to the set of social policy programs which are currently being used to sustain the recent reversal in ages at retirement. The basic question to be raised here, however, is about whether or not the U. S. government will ave to continue to implement the social policies and programs used to discourage the elderly from retiring at relatively younger ages in the future. In this paper, it is argued that labor productivity growth and improvement in work attitude prior to retirement will help the elderly find little difficulties in having higher standard of living, despite their further lengthening of life expectancy at birth and post-retirement survival chances, the latter being often called the "third life". Most American people hope that the social-policy programs that have promoted early retirement will remain unchanged in the first part of the 21st century while they will put significant financial burden on their future descendants who have to work in the paid labor market. Taking this observation in consideration, this paper concludes that the U. S. government has to focus more on developing the programs that improve work propensity and labor productivity among the currently working-age population rather than continuing to implement the programs that sustain the recent reversal in retirement ages.ment ages.
