The effect of research and development (R&D) expenditure on firm output is an interesting topic, but hardly explored in developing countries due to the unavailability of data. This study investigates this topic in the context of Vietnam by utilizing a novel dataset of 343 firms listed on the Vietnam Stock Exchange in the 2010-2018 period. The effect of R&D expenditure is examined under the production function framework. In order to obtain the robustness of the quantitative results, we estimate the production function with two coherent techniques including the OLS and 2-SLS. An instrumental variable regression technique is adopted to avoid the endogeneity problem between R&D expenditure and other variables. In our empirical analysis, we find that R&D expenditure has a positive and significant impact on output growth. The finding is robust in both OLS and 2-SLS frameworks. Besides, the output elasticity to R&D expenditure of our result is much higher than the estimated elasticity of other countries. The results imply that a 1% increase in R&D expenditure in Vietnam will help to expand the output more than a 1% increase in R&D investment in other countries. The findings from our paper provide important implications for firm managers, investors, and policymakers in Vietnam.

The purposes of this study were to identify education expenditure and to analyze contributing factors to total education expenditure for two children among married couples. For these purposes, total sample of 1,256 married couples those having two children of both pre-school aged and school aged were selected, and total sample was divided into four groups by first child's school aged; those were pre-school aged(375), elementary school aged(385), middle & high school aged(248) & college aged(248). Statistics used for the analysis were frequencies, means, percentile, and tobit and OLS analysis. The results were as follows. First, the households those having the first child of pre-school aged didn't spent for public education expenditure, while public education xpenditure of school aged increased continuously. The households having the first child of high school aged spent the most private education expenditure among four groups, however, total education expenditure of the households having the first child in college aged spent the most education expenditure were household head's age, family size, home ownership and financial asset amount, and elementary school-aged's factors were household head's age, education level, home ownership and total household income. Also, household head's education level, wife's expectation of future economy, residence, total household income had significant effects on total education expenditure in middle and high school-aged, and household head's job, home ownership, contact with neighborhood, residence and Engel's coefficient were significant variables in college aged.

This study compared the financial status between the employed-elderly households and the unemployed-elderly households, focused on income adequacy, expenditure adequacy and net wealth adequacy. Using data from 1997 KHPS, the lower financial status of the unemployed elderly households were found. Nine measures of financial status were used : income, per capita income, income-to-needs ratio, expenditure, per capita expenditure, expenditure-to-needs ratio, net wealth, net wealth-to-income ratio and net wealth- to-expenditure ratio. The results of this study showed that unemployed elderly households had 68%~77% of income adequacy and 72%~83% of expenditure adequacy for employed elderly households. Holding for gender, age, education, earners in the household, living area and home ownership constant, although the gap was getting smaller, significant differences between the unemployed-elderly households and the employed-elderly households were persisted. The result of this study indicated that the unemployed-elderly households and the employed-elderly households can not be regarded ac homogeneous group when public policies are developed.

This research is concerned with comparing fluctuation in the Korean and the US economies in order to ascertain the degree to which the former is influenced by changes in the latter. The aim of this research is to explore business cycles, to examine consumer expenditure in Korea and the US, and to discover the relationships between business fluctuation indexes and overall expenditure. Statistical data from the national statistics of Korea and the US during period from 1990 to 2015 were used. The instrument included a measure of GDP, unemployment rates, GDP deflator rate (inflation rates), and household income and expenditure. For the average annual household expenditures, food, apparel and transportation expenditure data were compared across the two countries. Data were collected separately from different (though comparable) sources and were analyzed using relatively straight forward statistical techniques. It was found that Korean and the US consumers' income and expenditure were greatly affected by economic fluctuations. Total expenditure and the expenditures for food and transportation were much influenced by business fluctuation in the US, whereas, the expenditures for apparel were much influenced by business fluctuation in Korea.

The purpose of this article is to analyse the expenditure structure of the welfare mix; in order to grasp the holistic feature of the Korean social welfare. Most of all, the article attempts to elaborate the estimation methods of social welfare expenditure by including the components from which has been excluded so far - indirect tax expenditure of the government, nursery payments of households, life insurance pay-outs for survivors, inter-household private income transfers and the value of caring work of the family. In so doing, the article estimates that the total social welfare expenditure including state, enterprise, market, NPOs and family reached at 24.7% of GDP in 2000, which is approximately 2.5 times more than public social welfare expenditure. It implies that non-state, private sectors dominates the structure of social welfare provisions in Korea. In addition, based on the analyses of the expenditure structure, the article defines the main feature of Korea's welfare mix as the 'mixed structure of the welfare mix dominated by the protective family', or 'expanded public sector, relatively limited market, and protective family'. Such a family-dominated welfare mix structure in Korea indicates that the fundamental source of solidarity of the Korean social welfare system is family and, therefore, the welfare regime of Korea can be classified as 'Conservative'.

Objectives : To document the use and out-of-pocket expenditure of complementary and alternative medicine(CAM) in Korean adult population. Methods : Nationwide, random-sampled, and population-weighted telephone survey was conducted. The sample size of respondents was 1,000(age over 18). The respondents were asked about their use, out-of pocket expenditure of CAM in the past 12 months. SAS 8.0 statistic package was used for checking the relevance between each variables by performing $x^2-test$ and variance evaluation. Results : In 2001, 64.0% of people experienced more than one alternative therapy and the beneficiary took therapy average figure of 2.07. Alternative therapies were generally used for health promotion(73.7%) rather than curing the disease(26.3%). The most common therapies included Medication(30.2%), Physical-therapy(21.9%) health implements(20.8%), herb medication(19.2%), diet therapy(14.3%) etc. Average annual out-of-pocket expenditure was ￡<192,186. Use varied according to age, living province, income, and education, while cost expenditure did according to sex, health condition, income, education. Conclusions : The use of CAM in Korea is very large and the expenditure for them is 22.6% of national medical expenditure. It shows great need of political and academic approach.

Purpose: To know for what the medical expenditure had been used and to seek the way how it can be efficiently redistributed, I investigated total medical expenditure according to the time period to death in the expired patients for recent 2 years. Methods: 21patients were enrolled in this study. Total medical expenditure including benefit charge and non-benefit charge charged to patients in in-patient department(IPD) and out-patient department(OPD) was counted according to the period for one year by death. Results: 94.7% of the total medical expenditure had been payed for admission-related expenditure and 89% during period 3 and 4 for 6months before death, which may be due to the more days of admission during those periods. 70.1% of the total expenditure had been charged on the admission-fee, room charge, diet, and administration of the fluid, medicines, and blood etc. Conclusion: Majority of medical expenditure has been used in the affairs being unable to improve the survival or quality of life of patients and during the periods closer to death. Here, it would be needed heartily to look for the best ways in detail how the idea of hospice can come true through nation-wide and social consensus.

Objectives: The purpose of this study was to compare predictions and measurements of the resting energy expenditure (REE) of overweight and obese adult women in Korea. Methods: The subjects included 65 overweight or obese adult women ranging in age from 20~60 with a recorded body mass index (BMI) of 23 or higher. Their height, weight, waist-hip ratio, and blood pressure were measured. The investigator also measured their body fat, body fat percentage, and body composition of total weight without fat using Dual energy X-ray absorptiometry (DXA) and measured resting energy expenditure by indirect calorimetry. Measured resting energy expenditures were compared with predictions from six methods: Harris-Benedict, Mifflin, Owen, WHO-WH, Henry-WH, and KDRI. Results: Harris-Benedict predictions showed the smallest differences from measured resting energy expenditure at an accurate prediction rate of 70%. The study analyzed regression between measured resting energy expenditure and body measurements including height, weight and age. The formula proposed by this research is as follows: Proposed REE equation for overweight and obese Korean women = $721-(1.5{\times}age)+(0.4{\times}height)+(9.9{\times}weight)$. Conclusions: These findings suggest that age is a significant variable when predicting resting energy expenditure in overweight and obese women. Therefore, prediction of resting energy expenditure should consider age when determining energy requirements in overweight and obese women.

The purpose of this study is to consider the socio-economic development and policy in each five-year economic development plan influences of urban households and to seek a plan of household stability and reasonable consumption expenditure on the aspect of Family economics. Data is based on the "Annual Report on the Family Income and Expenditure survey" of the National Bureau of Statistic Economic Planning Board, Republic of Korea and analyzed as follows: First, in analysis to the structure of consumption expenditure, the averaged percentage of each item to total consumption expenditure is estimated by each Economics Development Plan year. Second, in order to analyze the relative importance value of household consumption expenditure, priority correlation order is derived from comparison of characteristics of household consumption expenditures by multiple regression analysis. Third the patterns of consumption expenditure of salary and wage earner's households in all cities are estimated by the household consumption function, marginal propensity to consume, and income elasticity, according to socio-economic variable, and demographic variable. In the recent Korean economy, income level of household is increased and consumption expenditure level is largely increased because of the execution of economic development plan. But the improvement of income derives the increasment of the consumption needs and over-consumption trend is spread due to the import liberization. And above all, the reasonable household management and economic life are needed.

This study examined the effect of private educational expenditure on adolescent depression and somatic symptoms. The sample comprised 2,589 first-grade middle-school students who completed the 2018 Korea Children and Youth Panel Survey. Data were analyzed using ANOVA (the generalized linear model), multiple regression, and quantile regression analysis. The principal results were as follows. First, 15.15% of adolescents reported depression symptoms, and 15.57% reported somatic symptoms. Second, levels of depression were significantly different among classes with a different level of private educational expenditure. Third, depression level was significantly negatively associated with private educational expenditure, in that the higher the private educational expenditure, the lower the depression level. Fourth, the effect of private educational expenditure on adolescent depression was significant at the 70~90th quantile regression, suggesting that private educational expenditure was associated with a higher level of depression symptoms. The results indicate that private education was viewed as a consumption commodity rather than a complementary educational practice or investment in human capital. Private education as a commodity might induce the highly developed and costly private education market. In turn, there is an increased financial burden for education at one end of the social-economic continuum and depression caused by relative deprivation at the other end.
