Replacement rates which shows the ratio of retirement income relative to preretirement income is used for a valuable evaluation measures while discussing social security benefit levels or the adequacy of retirement income. However, replacement rates has been only used for an index for evaluating benefit level at the time of retirement or specific retirement period in advanced research projects. This article analyzes how much the uncertainty of survival has an influence on retirement income, and shows replacement rates in conformity with the period of survival as an index. The researchers named this index lifetime income replacement rates. Analysis based on this index shows both life replacement income rates of 38.3% in men's case and of 41.1% in women's case while enrolled for 20years in three pension plans - national pension, retirement pension and individual annuity.

This study explores a changing social expenditure structure of welfare states on new social risks, using logistic regression analysis with Panel Corrected Standard Errors Model on panel data of 1997-2007 years from 27 OECD nations. The result of this study presents that social expenditure structures have been adjusted with new social risk structure due to trade openness, female employment rates, and child population rates. Greater trade openness, higher women's employment rates, and lower child population rates are, more social investment expenditures are than income security expenditures. Rates of employment in service industries and elderly population rates are not statistically significant on the change of social expenditure structure. This result does not imply a complete switch from demand-based to supply-based social policy, but somewhat reflects transitions of a social welfare system for changing economic and social environments in order to sustain welfare state economically.

This paper intends to test the non-linear relationship between $CO_2$ emissions and income by employing cointegration model of the time-varying income elasticity. We select France, UK, Italy, Japan, US, China, India, Mexico and Korea and use non-parametric time series analysis on each country in order to estimate its own effect of income on $CO_2$ emission. The main results indicate that the $CO_2$ emission-income elasticities vary over time and the income elasticities of the Annex I countries tend to be higher in absolute terms than those of developing countries. In addition, we find that emission-income elasticities decrease for Annex I countries over time, whereas those for developing countries increase.

Aggregate income stability depends heavily on labor market institutions that stabilize or de-stabilize earnings. But, with the expansion of sate welfare programmes, public income transfers are also important sources of income stability for individual and families. Moreover, income stability is determinant factor of individual and family well being, there are another strategies of income stability in society. Family-based and community-based strategies are particularly important. Accordingly, the distribution of income stability in a given society depends on such institutional arrangements as market, family, state, and community. The purpose of this study is to analyse the income stabilizing role of family, state, and community. I found that stabilizing effect of the family and community was very strong in Korea. When institutional features of labor market and the state leave individuals exposed to market risk, they may be respond by relying more on family-based or community-based strategies of income stabilization. But, I can't deny the possibility of an inadequacy of these strategies in according to the rapid changes of family structures and informal networks. Therefore, state-based strategies of income stabilization should be more strengthened in Korea.

지난 40여 년간 고도성장을 통한 분배효과는 우리나라 사회의 계층구조의 형성에 주요한 기제로 작용하였으며, 적어도 1980년대까지는 긍정적인 영향을 행사한 것으로 이해된다. 그러나 1990년대에 시작하여 외환위기이후 본격적으로 시작된 소득 분극화의 진행은 소득격차의 가속화와 신빈곤의 구조화라는 심각한 사회문제를 야기하게 되었다. 이러한 소득의 분극화와 신빈곤의 형성에 가장 중요하게 작용하는 것은 바로 노동시장 내 질적이면 양적인 구조적 변화이다. (중략)

The demand for electricity has a considerable impact on various energy sectors since electricity is generated from various energy sources. This paper attempts to estimate the electricity demand function and obtain some quantitative information on price and income elasticities of the demand. To this end, we apply a lagged dependent variable model to derive long-run as well as short-run elasticities using the time-series data over the period 1991-2014. Our dependent variable is annual electricity demand. The independent variables include constant term, real price of electricity, and real gross domestic product. The results show that the short-run price and income elasticities of the electricity demand are estimated to be -0.142 and 0.866, respectively. They are statistically significant at the 5% level. That is, the electricity demand is in-elastic with respect to price and income changes in the short-run. The long-run price and income elasticities of the electricity demand are calculated to be -0.210 and 1.287, respectively, which are also statistically meaningful at the 5% level. The electricity demand is still in-elastic with regard to price change in the long-run. However, the electricity demand is elastic regarding income change in the long-run. Therefore, this indicates that the effect of demand-side management policy through price-control is restrictive in both the short- and long-run. The growth in electricity demand following income growth is expected to be more remarkable in the long-run than in the short-run.

This study evaluates the degree of the inequality of medical care expenditure and private health insurance benefits and the relation with household income inequality in korea health care system. This study used the 2014 korea Health Panel survey, and study method is Gini coefficient. The main results are as follow. First, average household income in 1st income quartile is 6,290,000won and 10st income quartile is 101,930,000won. And Gini coefficient of Korea household income is 0.3756. In other words, family income inequality is quite serious. Second, the Gini coefficient of the public institution supported medical care expenditure, such as health insurance and public assistance, is 0.0761, and the Gini coefficient of the expenditure of transportation fee and medical materials etc that don't supported is 0878. The inequality in medical care expenditure in public health care system and without public support aren't serious all. Third, Gini coefficient in excluding household medical care expenditure from household income slightly increased. That is, the medical care expenditure of our country household is the factor of aggravating the inequality of household income. Fourth, Gini coefficient of private health insurance benefits is 0.0927. Therefore, the ineqality in private insurance benefits is low. In addition, the Gini coefficient of the sum of private insurance benefits and household income is 0.3672. it decrease from Gini coefficient(0.3756) of household's. Private health insurance perform the functions somewhat weaken household income inequality. However, it is very little improvement.

사회가 점점 고도화, 다양화, 고속화 하여가는 것과 비례하여 화재에 대한 위험성도 증대하며 일단 화재가 발생하면 그 피해 역시 막대하게 커지고 있습니다. 인간의 생활수준이 의식주를 해결하기에 급급하던 수준을 벗어나면, 즉 소득수준이 높아지면 "우선 살아야 한다"는 의식에서 "어떻게 잘 살 것인가"하는 방향으로 의식의 변화가 일어난다고 합니다. 인명을 존중하고, 생활환경 도시환경 노동환경에 있어서의 안전방재에 대한 의식도 높아진다는 것입니다. 일반적으로 그 의식의 변화는 일인당 국민소득 약 만불($10.000.-)전후에서 일어난다고 합니다. 이와 같은 사회배경을 바탕으로 섬유재료에 있어서도 보다 난연 또는 내열소재를 필요로 하게 되었습니다.

This study analyzed the annual difference of firm's book income, taxable income and BTD that before and after the 2009 corporate tax rate cut and 2018 corporate tax rate increase. ANOVA analysis was performed for each item by year, and post hoc was performed after homogeneity test of variance. The research results are as follows. First, the book income at corporate tax rate cut was higher than taxable income, and BTD in 2008 was significantly different from other years. Second, the book income at corporate tax rate increase was less than taxable income, and BTD in 2017 was also significantly different from other years. In other words, the firm is performing appropriate profit adjustments to reduce of tax burden when the corporate tax rate changes. Because of this, the BTD in the year immediately before the corporate tax rate change is different from other years.

최근 글로벌화의 시대의 도래로 인하여 과거와는 달리 사람들의 국제적 이동이 빈번하게 발생하고 있다. 과거보다 잦은 국제 인구이동으로 인하여 각 국가 간 조세협약이 매우 중요해졌으며, 이제는 과세측면도 양국가간의 조세협약에 따라 과세를 하여야 한다. 본 연구는 이러한 상황 하에서 연금수령 시 국가 간 조세측면을 고려하였을 때 과세형평의 문제점을 살펴보고 이에 대한 개선방안을 제시하고자 한다. 과거에 비하여 최근의 연금세제 또한 많은 변화를 가져오고 있어 이제는 한 국가 내에서 만의 연금세제를 고려할 것이 아니라 글로벌화 시대에 부응하는 연금세제로의 변화가 필요하다. 이러한 주된 이유로는 국제이동 인력의 증가로 거주지국 과세원칙과 원천지국 과세원칙의 혼용뿐만 아니라 전세계소득(world-wide income)에 대하여 과세가 되므로 국제적인 이중과세의 위험에도 직면하게 되기 때문이다. 본 연구는 이러한 상황을 감안하여 최근 급증하고 있는 해외 이민지들에 대한 국제적 연금조세 측면을 살펴보고자 하였다. 해외에 거주하는 사학연금 가입자에게 발생하는 과세상의 문제점을 구체적으로 살펴보고 이에 대한 개선책을 살펴보고자 하였다. 해외거주 연금수령자는 국내에서 지급하는 연금에 대하여도 전세계소득으로 해외 세무당국에 보고를 하도록 하고 있는데, 국민연금은 각 국 간의 사회보장협약의 체결로 인하여 과세를 하지 않는 반면, 특수직역연금 수령에 대하여는 거주지국의 전세계소득에 포함되어 국외 거주지국 과세대상에 포함되는 문제점이 있다. 특히 캐나다에서 연금을 수령하는 경우에는 더욱 확연한 차이가 나타나게 된다. 본 연구에서는 다음과 같이 주장하고자 한다. 첫째, 한국·캐나다 조세협약 제18조의 수정을 통해 현행 사학연금 수급자의 연금소득에 대하여 비과세할 필요가 있다. 사회보장법률에 따라 지급하는 연금에 대하여 비과세하는 현행 문구를 한국의 공적연금으로부터 지급하는 연금으로 지급하는 급부로 수정할 필요가 있다. 둘째로 사회보장법률에 의해 지급하는 연금을 별도로 언급할 필요가 있다. 이를 통해 국민연금 가입자와 특수직역연금 가입자 간의 과세 형평성을 달성할 필요가 있다. 본 연구는 기존연구에서 간과되었던 연금세제의 국제적인 측면을 중심으로 국제적 인력의 이동에 따른 연금세제의 변화를 살펴보고자 하였다. 특히 최근에 우리나라 사람들이 가장 많이 이민을 가고 있는 캐나다를 중심으로 연금세제 측면을 살펴보고자 하였다는 측면에서 연구의 의의가 있다고 할 수 있다. 본 연구에서 제시된 정책적인 제안은 과세당국과 해외 연금수급자에게 편익을 제공할 것으로 본다.
