As a results of comparing with fire occurrences and gross national income(GNI), annual fire increasing rate has been 5.6%, and that of GNI has been 11% for the past 55 years. As GNI shows 5.4% higher than fire occurrences, economy growing rate is faster than that of fires. In addition, study has been done every 10 years from 1950's to 2000's. Fire occurrences increase twice as much annually and GNI increases above 3.3 times as much.

This paper aims at analysing what impacts the experience of self-employed business have had on the income mobility. Since 2000s, the flexibilization of labor market and the population aging led to the increase of the number of self-employed job as many retirees at the age of early 50s has set up the self-employed business as a bridge job. However, previous researches just have emphasized on the impoverishment of the self-employed, but not focused on what different effects the experience of self-employed had on the income class mobility by age group. This paper compares the difference in the income class mobility by age group and employment status, and analyses its longitudinal trends. According to the result, as a whole the experience of self-employed has positive effect on the upper mobility of income class, but it become disadvantageous for the upper mobility as the age goes up. When belonging to the age group over 60s, the experience of self-employed rather increases the risk of lowering income class. Just as the experience of self-employed has different effects on income class mobility by age group, so the differentiated measures for age groups are demanded.

The purpose of this study was to examine how much the cost of marriage ceremony has increased according to the economic growth. The relationship between marriage expenditures and other comparison variables such as per capital GNP, monthly income, consumer price index was particularly examined. All the money values were adjusted by consumer price index. Data from the Central Committee for Promotion of Saving were used in this study. The results of this study follow. First, nominal and actual total outlay of marriage ceremony has continuously increased. Total marriage ceremony cost was positively correlated with the housing price so that bridegroom’s outlay were greater than that of bride’s one since bridegroom was more likely to have the responsibility for the price of new couple’s house. Second, it was found that increased percentage rate of marriage ceremony cost was greater than that of national economic growth. The total marriage expenditure was about 10 times as much per capital income in 1990. Third, it was revealed that housing cost increased three times from 1990 to 1995, and marriage ceremony expense was accordingly increased twice during the same periods. Such trends tend to increase continuously. Last, the marriage cost percentage to monthly income called marriage expenditure share increased by 1990 and then decreased. Such a decreasing trend can be explained by the increased amount of income partly due to the higher wage rate compared to other conditions since 1990.

The purpose of this document is to provide the direction of the policy for welfare of the elderly, by identifying the problems and status of the welfare service for the elderly. The primary source of degrading the living standard of the elderly is the increase of the elderly population and life longevity. The Welfare service for the elderly to enhance the poor living level of the elderly population should be established, to compensate their former economic and social contribution in the society and also to promote the basic human right. The agenda to achieve this goal sums up like these : First, the basic living of the unhealthy elderly belonging to the low-income group, such as government-provided income and medical service should be provided. Second, for those with working ability, more opportunity for working and social activities should be given, focusing on expanding the employment rather than adding income. Third, for those with middle and high income, silver industry and pastime activities should be nurtured. Lastly, rather than institutional protection for the elderly, the welfare service for those staying home should be enforced, thus naturally leading to the family support for the elderly. There cannot be a sound policy for welfare and improvement of living standard ignoring the Well-being of the elderly population. The effort to better the welfare for the minority groups who compose the base of the social base will, eventually, result in the progress of the entire society.

The importance of the old age income security will increase for an aging society due to the deepening income polarization. The National Pension(NP) is a representative Social Security scheme in charge of old age income security as well as income redistribution for the insured. Studies by Kim (2002), Kim et al. (2003), and Hong (2013) have reported the possibility of unsatisfactory income redistribution of the NP. Recently Choi (2015) attributed those results to an unnoticed defect in the benefit formula. This study is a test for the unsatisfactory income redistribution of the current National Pension using early participants who have now become pensioners. The method aggregates cohorts and combines individual history data before the year 2013 and the results of the actuarial projection model of the 2013 after the year 2014. The results are divided by measures taken. The redistribution is obviously progressive by the income replacement rate; however, it is significantly regressive when measured by the net benefit theoretically as more plausible. Considering the effect of differing lifetime contribution year among income classes, the regressive redistribution will prevail more in the future pensioners.

Objectives: This study examined the intake of energy and macronutrients among elementary, middle, and high school students according to household income before the COVID-19 pandemic (2016-2019), during the social distancing period (2020-2021), and after the social distancing measures were lifted (2022). Methods: We included 5,217 students aged 5-18 from the Korea National Health and Nutrition Examination Survey (KNHANES) conducted between 2016 and 2022. Dietary intake was assessed using one-day 24-hour dietary recalls. We estimated the least squares means (LS-means) of intake according to household income for each period using a weighted linear regression model, adjusted for age and sex. Differences in LS-means between the periods were analyzed using the t-test. Results: During the social distancing period, the LS-means of energy intake among students decreased significantly by 143.2 kcal/day compared to pre-pandemic levels (P < 0.001). Students from low-income households experienced a more pronounced decrease in energy intake (-379.1 kcal/day, P < 0.001) and macronutrient intake compared to those from other income groups. Energy intake at school significantly declined for all income groups during the social distancing period compared to before the pandemic. No significant changes in home energy intake were observed among low-income students, whereas there was an increase for students from higher-income groups. Before the pandemic, 8.5% of students from low-income households reported insufficient food due to economic difficulties; this figure rose to 21.3% during the pandemic. Conclusions: During the pandemic, students from low-income families experienced significantly lower intake of energy and macronutrients compared to pre-pandemic levels. The most substantial reductions were noted among low-income students, largely due to the lack of compensation for decreased school-based intake with increased intake at home.

This paper considers a heterogeneous agent dynamic general equilibrium model and analyzes effects of an increase in labor income tax rate on labor market and the aggregate variables in Korea. The fiscal policy regarding how the government uses the additional tax revenue may take the two forms: 1) general transfer and 2) earned income tax credit (EITC). The model features are as follows: 1) Workers are heterogeneous in their productivity. 2)Labor is indivisible, hence the analysis focuses on the variation in labor supply through the extensive margin in response to a change in fiscal policy. 3) The incomplete markets are introduced, so individual workers can not perfectly insure themselves against risks related to stochastic changes in income or employment status. 4) The model is of general equilibrium, hence it is equiped to analyze the feedback effect of changes in aggregate variables on individual workers' decisions. In the case of general transfer policy, the government equally distributes the additional tax revenue to all workers regardless of their employment states. Under this policy, an increase in the labor income tax rate dampens work incentives of individual workers so that the aggregate employment rate decreases by 1% compared with the benchmark economy. In the case of EITC policy, only employed workers whose labor incomes are below a certain EITC ceiling are eligible for the EITC benefits. Unlike the general transfer policy, the EITC induces low-income workers to participate the labor market to be eligible for EITC benefits. Hence, the aggregate employment rate may increase by 2.7% at the maximum. As the EITC ceiling increases, too many workers can collect the EITC but the benefits per worker becomes too little so that the increase in employment rate is negligible. By and large, this study demonstrates that EITC may effectively raise the aggregate employment rate, and that it can be a useful policy tool in response to the decrease in the labor force due to population aging as observed in Korea recently.

This paper aims to analysis working-time of Korea focusing on "the difference and the distribution" by a stratum. Classifying working-time into four categories including marginal part-time, part-time work, standard-time work and long-time working, it compares the relative distribution by income quintile. The outcome is as following : 20% of low-ranking income quintile are (marginal) part-time working, 60% from income quintile 2 to 4 are in long-time working and 20% of top-ranking income quintile are in the standard-time working in overall. Working-time classes can be divided up into three: short time-low income of type 1, long time-medium income of type 2 and standard time-high income of type 3. Analysing working time type, the low wage-short time, medium wage-long time and high wage-standard time by the wage per month and low wage-very long time, medium wage-long time and high wage-standard time by the wage per hours are confirmed. Also, stratification of working-time has been intensified in terms of age, jobs and work status. Policy implication from this study is that the increase of minimum wage to the lowest income class and creation of employment by the reduction of working-time to the medium income class could be effective policies.

As the rapid development of economy in China, the problem in income gaps become a tough and sensitive social problem. Under this social background, this research try to find the main reasons of the income gap among the East China, West China, and the central China, basing on the analysis of its actuality and forming, and then put forward some solution plans. The research shows that in different development levels of China influencing factor of urban-rural income gap is also different. Take East China for example, the education support plays an important part of narrowing income gap. The influence of education support on urban-rural income gaps more significant than industrialization, what is more, its influence has the more reinforce trend, while in the less developed central and western part in China, what can narrowing income gap significantly is industrialization and the support for agriculture. Therefore, in order to solve the problem of income gap between urban and rural areas in China radically, it is not enough to perform medical insurance reform and social insurance reform in the whole county. Besides this, we should perform other kinds of reformation countermeasures which have their regional characteristics. For example, in eastern, the regional governments should reinforce the education system; in central china, they should focus on developing industry; in western, the regional governments should increase the expense to support the agricultural development, and so on. With these countermeasures, they could not only relieve the gap between urban and rural areas in China, but also ensure to develop economy substantially and stably in the whole country.

Lately, rapid increase of household debt and economic change has affected cash flow of household, insolvent risk has increased by high repayment burden of the principal and interest. Previous researches was progressing various discussion, composed objective repayment burden index about household debt. But it was relatively insufficient about perception of consumer. This research compare and analysis determinants of subjective repayment burden in household debt by income quintile, using 2016 Household Financial Welfare Survey. The research result is follows. The income 1 and 2 quartile groups have the higher monthly rent and credit card loan and the housing preparation loan ratio, the higher burden on repayment of the principal and interest. The Income 3 and 4 quartile groups have the higher 60s or older and member of household and real estate mortgage loan, the higher burden on repayment of the principal and interest. The Income 5 quartile group has the higher loan ratio for debt repayment preparation, the higher burden on repayment of the principal and interest.
