The purpose of the study is to estimate objective retirement wealth adequacy and subjective retirement wealth, and to compare two of them. Also the factors relating to those wealth readiness were investigated. The data used was 422 pre-retiree who were married and under 65 years old and SPSS 20 was used for the analyses. The results showed that objective reirement wealth readiness was 37.6% and subjective retirement wealth adequacy was 40.9%. Almost half of the sample (44.8%) were indicated to have no objective retirement wealth, but only 5.9% was answered to have no retirement wealth. Both subjective and objective retirement wealth adequacies tended to increase with older age, higher income and lower average propensity to consume groups. The difference between objective and subjective retirement wealth adequacies was smaller with getting older. According to multi-variable analyses, two factors were found to affect on both the subjective and objective retirement wealth adequacies, which were income and retirement asset. The respondents were found to be not able to estimate their own retirement wealth adequacy objectively. The correlation between the subjective and objective retirement wealth adequacies was 0.344. Among the respondents, 74.4% answered bigger number on subjective retirement wealth than their objective retirement wealth.

The purpose of this research is to analyze the wealth effects of home-owning baby-boomers on household consumption on non-durable goods in the Seoul Metropolitan Area. In so doing, this empirical study utilized the Korean Labor and Income Panel Study (KLIPS) of 2002 and 2012. The statistical findings reveal that household wealth in the period had sharply risen in household income, asset, debt and consumption, and the substantial increase came from growing income and consumption embedded into an expansionary stage of the family life cycle. Further, housing wealth had a much greater effect on consumption expenditure than did financial asset in 2012 while financial wealth effect was larger than housing wealth effect in 2002. Housing wealth effects had become far stronger as the age of the baby-boomer householders increased. As the baby-boomers are close to the retirement stage, post-retirement income security becomes of concern, so that the wealth effect of real estate income as an income alternative for retirees is explicit. The results imply that retirement of baby-boomers is likely to reduce consumer spending, aggravating slowdown of the real economy. Thus, diversification of household asset portfolio in a pre-retirement period is of great significance in maintaining adequate household consumption in later life.

In this paper we study an optimal consumption, investment and retirement time choice problem of an investor who receives labor income before her voluntary retirement. And we assume that there is a negative wealth constraint which is a general version of borrowing constraint. Using convex-duality method, we provide the closed-form solutions of the optimization problem.

본 연구의 목적은 은퇴자들이 은퇴 후 삶을 영위하기 위해 필요한 은퇴자금의 충분성을 분석하고 그에 영향을 주는 요인을 확인하는 것이다. 은퇴자금 충분성을 평가하기 위해 은퇴소요자금의 산정을 통한 객관적 측면과 은퇴자 스스로 인식한 주관적 인지 측면으로 구분하였다. 또한 두 가지 측면으로 분석된 은퇴자금 충분성의 결정에 영향을 미치는 요인을 각각 규명하였다. 본 연구는 한국투자자교육재단에서 50세 이상 은퇴자들을 대상으로 2007년 실시한 은퇴자조사의 자료를 토대로 분석을 실시하였다. 그 결과 우리나라의 은퇴자들은 재정적으로 충분히 준비되지 못한 상태에 있다는 점이 확인되었다. 객관적 충분성 분석 결과에 따르면, 거주주택을 제외한 모든 자산을 은퇴자산으로 사용할 경우 23.2%의 은퇴자만이 현재의 지출을 지속적으로 감당할 수 있을 것으로 나타났다. 또한 조사대상자의 25.7%가 본인의 은퇴자금이 은퇴 후 생활을 영위하는데 있어서 충분할 것이라고 인지하고 있었다. 은퇴자금의 객관적 충분성과 주관적 충분성의 일치 정도를 비교해보면 전체의 약 1/4에 해당하는 23.8%의 은퇴자가 자신의 은퇴자금 충분성 분석결과와는 다르게 인지하고 있는 것으로 나타났다. 또한 12.9%의 은퇴자들은 은퇴자금이 충분하지 않을 것으로 추정되었으나, 자신의 은퇴자금이 충분한 것으로 평가하고 있었다. 은퇴자금의 충분성에 영향을 주는 요인을 분석한 결과 가계소득이나 자가 소유 여부 등과 같은 재정 변수는 긍정적으로 유의하게 나타났으며, 은퇴 준비 여부 또한 중요한 변수임이 확인되었다. 연구 결과들을 토대로 은퇴자들과 예비 은퇴자 가계를 위한 은퇴대비 방안과 정책적 시사점을 논의하였다.

The purpose of this study was to examine retirees' attitudes towards change of living standards. The data were drawn from the 2007 Korean Retiree Survey, as carried out by the Korean Investors Education Foundation. The major findings are as follows: 1) Some retirees were not well-prepared for retirement, i.e., they lacked financial consultation, had low personal financial literacy, and lacked sufficient wealth. Retirees suffered from health difficulties, loneliness or a sense of alienation, family conflict, or lack of pastimes. 2) Certain groups recognized the change of living standards for retirees as either positive or negative. Retirees who recognized the change of living standards as negative were not well-prepared for retirement, had low personal financial literacy, and lacked sufficient wealth. They also suffered from health difficulties, loneliness or a sense of alienation, family conflict, or lack of pastimes. 3) There was a strong probability for the negative recognition group not to be well-prepared for retirement, having low personal financial literacy, and lacking in sufficient wealth. There was a strong probability for the negative recognition group to suffer from health difficulties or lack of pastimes. Based on these findings, this research suggests that retirees should prepare for retirement with a positive attitude.

In this study we propose a model of optimal retirement, consumption and portfolio choice of an individual agent, which encompasses a large class of the models in the literature, and provide a methodology to solve the model. Different from the traditional approach, we consider the problems before and after retirement simultaneously and identify the difference in the dual value functions as the utility value of lifetime labor. The utility value has an option nature, namely, it is the maximized value of choosing the retirement time optimally and we discover it by solving a variational inequality. Then, we discover the dual value functions by using the utility value. We discover the value function and optimal policies by establishing a duality between the value function and the dual value function. The model and approach offer a significant advantage for computation of optimal policies for a large class of problems.

OECD 국가들은 인구고령화로 인해 공적연금의 재정안정성이 위협받자 공적연금의 노후소득보장 기능을 축소하는 대신 사적연금을 활성화해 왔으며, 세계에서 가장 급속한 인구고령화를 경험하고 있는 한국 역시 주요국의 정책을 답습하고 있다. 하지만 주요국과 달리 한국은 가구 자산의 대부분이 부동산 자산으로 구성되어 있다는 특징이 있다. 전체 자산에서 부동산 자산이 차지하는 경제사회적 중요성으로 인해 부동산의 자산효과는 거시경제정책의 주요 도구로 활용되어 왔다. 본 연구는 부동산의 가격변화가 사적연금(개인연금+퇴직연금)의 납입액에 미치는 영향을 분석하였다. 재정패널조사 자료를 활용해 이원고정효과모형(Two-Way Fixed Effect Model)으로 분석한 결과, 부동산 가격이 1% 증가할 때 사적연금 납입액은 0.171% 증가하는 것으로 나타났다. 즉 부동산의 가격변화가 사적연금을 통한 노후준비에도 긍정적인 것으로 분석되어졌다. 이러한 결과는 향후 부동산 시장이 위축될 경우 소비감소뿐만 아니라 국민들의 노후준비에도 부정적일 수 있다는 것을 시사한다.

This research intends to find out the impact of housing wealth of home-owning pre-retirees and older adults consisting of young-old, middle-old and old-old groups on their household consumption. In doing so, this research analyzes 2,350 home-owning households by utilizing the 17th Korean Labour and Income Panel Study (KLIPS). The results show that housing wealth has a statistically significant effect on non-durable consumption of the pre-retirees, and young-old and middle-old groups of older adults, and housing wealth has a much stronger effect on household expenditure than does financial wealth or real estate. It's found that the consumption elasticity is particularly greater for female-headed households living in SMA, residing in apartments, holding a lower debt-to-asset ratio and being a pensioner. The empirical findings imply that the old-old group of older adults is unlikely to actively tap into their housing windfalls since housing asset becomes the last to dispose in the course of an individual's life. As housing wealth effects are especially strong when liquidity constraints faced by older adults are removed, it's of significance to substantially reduce household debt before retirement in order to constantly maintain an adequate level of household consumption or to promptly prepare for future contingencies.

In this paper, we evaluate life annuity plans for Korean pre-retired single and married couple participating Korea National Pension (KNP) and find optimal life annuity strategy by using utility-based measurements called AEW (Annuity Equivalent Wealth). Specifically, we extend a previous study to obtain a detailed optimal combination of annuitizing age and wealth in terms of percentage of net wealth at the time of retirement. A nonlinear optimization model is formulated with the objective of maximizing utility on consumption and bequest, and the dynamic programming (DP) technique is used to solve this problem. We find that there exist consistent patterns in optimal combinations of annuitizing age and wealth. Also, for all cases the optimal combination is significantly better than several other combinations. The results indicate that using the optimal approach can be beneficial to practitioners in insurance industry and prospective purchasers of life annuity. We conclude the paper with some discussions and suggestions.

We investigate an optimal retirement time and consumption/investment policy of a wage earner who expects to find a better investment opportunity after retirement by being freed from other work and participating fully in the financial market. We obtain a closed form solution to the optimization problem by using a dynamic programming method under general time-separable von Neumann-Morgenstern utility. It is optimal for the wage earner to retire from work if and only if his wealth exceeds a certain critical level which is obtained from a free boundary value problem. The wage earner consumes less and takes more risk than he would without anticipation of a better investment opportunity.
