This study aims to propose for the K-beauty industry by analyzing the consumption situation. The data used the household trend survey and GDP from 06' to 16' provided by the National Statistical Office. The analysis results of the influencing factors of expenditure on the K-beauty service industry per household resulted in the increase of expenditure on hair and beauty services and their goods when ordinary income decreased, it was possible to understand the similarities between the change of Engel's coefficient. It was difference in the proportion of consumption of beauty services account by income quintiles.The increase of the GNI had an effect on that of the consumption of K-beauty. The above results show that beauty service industry is relevant to the items of households' income and expenditure. Plans are needed to take into account national economic trends and consumption patterns.

The objective of this paper is to analyze expenditure structures and impact factors of household's transportation cost in order to provide policy-maker with quantitative and economic information for reducing household's transportation costs, using 1995-2007 household survey data. For this purpose, this study performed various economic analysis, including econometric regression analysis and income re-distributional effects. The four models were separately estimated with dependent variable (personal and public costs, public transit and private car costs) and independent variables (family, employ, age, education, cars, household income, region dummy variable). In addition, We analyzes impacts of transport policy instruments on the transportation expenditure. These instruments include changes of oil price and public transit fare, reform of public transport system, and extension of subway facilities. Finally, income re-distributional effects before and after transportation expenditure, using Pechman-Okner (PO) index and Wolfson index.

In marketing, the thematic conceptual study related to hedonic consumption with product symbolism contributed to symbolic consumerism and its hedonic experience. Researching how consumers deal with expectations for unexpected income or windfall gains helps understand what makes them enjoy experiences. This paper discusses the trade-off relationship between hedonic and utilitarian consumption. it aims to determine when and why people choose hedonic (pleasant) or utilitarian (material) products under windfall gains. We suggested five hypotheses, and through a series of experiments, respondents preferred hedonic to utilitarian goods when lottery amounts increased and the probabilities did not discriminate between two products. the preference order was not discriminated in the hedonic, utilitarian goods. the shape of preference revealed an opposite direction (U vs. invert-U)when the winfall amounts increased. and when the discounting rates varied, the consumers' preference order was expected to change. Subjects selected hedonic goods the most, utilitarian goods second, and cash rewards were the last choice. Therefore, stimulating consumers' hedonism and promoting hedonic experiences might be effective marketing tactics and strategies.

The cultivation area of rice as staple grains is decreasing in the domestic situation in Korea. Import volume of a duty in foreign rice is 409,000 tons for a year regardless increasing of production per unit area and decreasing of rice consumption. The total stock of rice is increasing cumulatively despite the effort for production mediation of rice. Therefore, maintenance of cultivation area and reduction of production are necessary for national foodstuffs security problems. Development of environment-friendly and low-carbon technology as alternative of global warming and aging of farm labor power is very important responsibility for descendants with creation of sustainable agriculture environment. As alternative for demand and supply stabilization of rice from all angles, first stage: extension of environment-friendly cultivation area as 17% Jeollanam-do level with maintenance of cultivation area under the present circumstances, second stage: extension of environment-friendly cultivation area as 25%, third stage: extension of environment-friendly cultivation area as 35%. From above mentioned scenario, reduction of rice production (60,000 tons), increases of production cost (59,200,000,000 Won), and reduction of income (201,500,000,000 Won) are estimated in first stage. Reduction of rice production (90,000 tons), increases of production cost (122,100,000,000 Won), and reduction of income (313,700,000,000 Won) are estimated in second stage. Reduction of rice production (380,000 tons), increases of production cost (222,000,000,000 Won), and reduction of income (464,500,000,000 Won) are estimated in third stage. From analysis results for partial tillage in transplanting cultivation complex (10ha), rice production is decreased 1.3~1.5 ton by complex. Production cost of rice is decreased and increases of income cultivation type. Gradual extension of environment-friendly agriculture and low-carbon partial tillage could be expected for environment maintenance of the territorial integrity, confidence of consumer, and high-efficiency of low-cost.

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.

Using matching and difference-in-differences estimation method, this study estimates causal effects of health shocks on employment and income of full-time workers aged 40-55. Acute hospital admissions lower significantly the employment probability and earnings. The changes in employment and earnings persist up to three years after the health shock. The economic impacts of health shocks vary by socioeconomic status and job characteristics among individuals. Irregular workers are more likely to leave their jobs after health shocks than regular workers. Among irregular workers, the probability of leaving labor market after health shock decreases with the size of the firm.

Lately, as the problem of the aged poverty becomes a big social issue, this paper studies the problem of financial stability with respect to the income and consumption of before-and-after retirement generations. After dividing the data in Korean Longitudinal Study of Ageing(KLoSA) into retired and non-retired groups, this study compares the difference among ageing groups by cross analysis and t-test. First, the result tells that the total personal income of retired group is lower than the one of non-retired group. Second, the public pension income benefit ratio of retired group is only 30% of it's total income, and the amount of public pension appears to be 40% of the total pension income. The benefit ratio of the personal pension income is low as about 1% in both groups, The private transfer income of the retired group takes relatively large portion in its total personal income. Third, as people gets older, financial stability gets worse because consumption does not decrease as much as the income decreases. Fourth, it is turned out that the expectation of old life supporting from nation is low in both groups. Fifth, the factors that affects the income of the public pension in the retired group are gender, age, education, and health status, when compared with the factors to the personal total income of the non-retired group. In terms of policy, this paper emphasizes the needs of the intensification of the public pension and the support for the revitalization of the personal pension.

A study was conducted to determine whether there is a difference in the incidence of kidney cancer according to income level and the difference in delayed diagnosis. To this end, the incidence of kidney cancer in Korea was analyzed by income level and by stage. From 2015 to 2017, a national kidney cancer cohort was established by linking the KCCR(Korea Central Cancer Registry), NHISS(National health insurance sharing service), and the HIRA(Health insirance review and assessment service) database to calculate the kidney cancer incidence by stage and income level. During the study period, the incidence of kidney cancer in Korea increased in all income deciles, but decreased only in the medical aid population. The incidence of kidney cancer in Korea was 7.35 per 100,000 people, and 83.54% of them were locoregional kidney cancer. In the top 20% of the income decile, there was a high incidence of 21.46 cases per 100,000 people, among which 18.37 cases were locoregional kidney cancer. On the other hand, even after adjusting for risk factors related to kidney cancer, it was confirmed that the lower the income level, the higher the risk of being diagnosed with kidney cancer with distant metastasis (lowest income 20% adj.OR 1.807, 95% CI 1.411-2.222). In the insured population, the risk ratio of being diagnosed with unknown stage was 1.926 (95% CI 1.317, 2.816). The higher the income level, the higher the frequency of early cancer diagnosis, but the lower the income level, the higher the risk of being diagnosed with metastatic kidney cancer or an unknown stage, so health inequality according to income level was observed.

This paper estimates the effects of imaginary repeated increases in excise duties on fuel oil consumption and on their income redistribution according to changes in consumer price index, if the inflation indexation system was introduced right after the second Energy Tax Reform ended in July, 2007 in Korea. In fact, nominal excise rates have not been adjusted since 2007. As a result, the real excise rates on fuel oils have been diminished inversely proportional to the consumer price index. Own- and cross-price elasticities of fuel oils such as gasoline and diesel oil are estimated under the general equilibrium framework based on the linear expenditure system. Counterfactual analyses through microsimulation in a static model are adopted to estimate the effects of introducing inflation indexation into the fuel tax in 2007 when the second Energy Tax reform ended on the fuel consumption and income redistribution in 2014. Microsimulations suggest that its introduction could have reduced the consumption of gasoline and diesel oil by 8.8% and 5.4%, respectively, ending up with increased excise revenue by 11.9%. The revenue increase in spite of decreased consumption is mainly because their demands are price inelastic. It could also have increased positive income redistributive effect by 0.01%p (from 0.12% to 0.13%), which is measured in terms of percentage decrease in Gini coefficient. In other words, the fuel excise on the two fuel oils decreased by 0.13% the Gini coefficient of before and after fuel tax income in 2014. This implies that the inflation indexation could have enlarged the income redistributive effect up to 0.13% in 2014, if it is introduced in 2007.
