Benefit-cost ratios are estimated using life-expectancies of the national pension old-age pensioners in Korea and a compared to whole nation. To obtain the ratios, future mortalities are estimated by multiplying the ratios of experienced mortalities for old-age pensioners to those of the whole nation and the future mortalities of the whole nation projected on an expanded CBD model. The results indicate that the life expectancies of old-age pensioners are longer than the whole nation that lead to higher benefit-cost ratios for old-age pensioners.

Recently, Korean government documented the plan to cope with the situation related to rich pensioners of Basic old-age pension. The purpose of this paper is to verify that how many rich pensioners are existing and to evaluate government reform plan's validity and effect. Main results are as follows; firstly, if the definition of rich pensioners is on the top 10%, the proportion of them would form 2.9% of total. And then, an amount of expenditure for them is only 2.6% of total. Secondly, in terms of disposable income, debt, and transfer income from child, the household who would be applied by government's plan is not richer than other household who is in the same living standard. And then, if the government's plan enforced, the effect might be very small. Lastly, the plan of government will discriminate against persons who support their parent. As a result, Basic old-age pension will be worsen. This paper should underline that the government's reform is only the 'hidden' retrenchment strategy in order to introduce a standard of the obligation to support own parent in the state without scientific prediction and serious discussion of negative public opinion. That is why, this is the same as the 'Trojan Horse'.

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.

This paper discusses life expectancy differentials of beneficiaries of national pension old-age benefit and benefit-cost analysis in Korea. These results are useful indicators for the assessment of retirement income security of beneficiaries and old-age benefits. This paper analyzes benefit-cost ratio, internal rate of return and generation transfer amount, using life tables by lifetime incomes. The result of the actuarial analysis for male life expectancy is approximately 21.69 to 24.63 years. The result of the actuarial analysis for female life expectancy is approximately 27.63 to 29.81 years. The result of the actuarial analysis of low income level is that the benefit-cost ratio is lower approximately 2.68 to 4.83%, the internal rate of return lower approximately 0.00 to 0.74%, the generation transfer amount lower approximately 3.00 to 5.74%, than total income level. The result of the actuarial analysis of high income level is that the benefit-cost ratio is higher approximately 2.07 to 4.98%, the internal rate of return higher approximately 0.03 to 1.73%, the generation transfer amount higher approximately 2.53 to 9.68%, than the total income level. The results by income varies due to the effect of income redistribution and life expectancy on the national pension.

Essential urban services that protect citizens' lives and property such as firefighting, disaster and crime prevention, should be provided equally to all citizens regardless of their location, personal status, and income. This paper analyzes the equality of firefighting services in spatial and social perspective in Daejeon Metropolitan City. For this the accessibility of fire service was analyzed for all settlements in the city. In addition, the distribution status of low-income class and forecasted income each region were compared to analyze whether the area where fire fighting service in 5 minutes was related to the distribution of income class. According to the analysis, the area where fire service can be provided within 5 minutes was 46.2% of Daejeon, and 98.0% of the population lived in this area. The proportion of old-age pensioners living in the area where fire service can't be provided within 5 minutes was 52.7%, reise than the average of 7.14% in Daejeon. In addition, in areas where the provision of firefighting services exceeds five minutes, the forecasted income tends to be lower in areas where service arrival is delayed. Therefore, it can be said that the economically vulnerable people living in the outskirts of Daejeon are not provided with equal urban services, and policy consideration is required accordingly.
