The purpose of this study is to investigate the characteristics of the clothing consumption expenditures by the business cycles in Korea during the period of first quarter of 1979 to second quarter of 1998. Business cycles were examined using data GNP from the National Accounts published by the Bank of Korea and clothing expenditures from the monthly statistics of Korea published by the National Statistical Office of Korea. Data were analyzed by regression analysis standard deviation sample cross-correlation coefficient and skewness statistics. The main results are as follows. 1. During the period of 1979.I-1998.II GNP and per-person consumption expenditures for clothing and shoes have continuously increased except during 1980 and the recent depression of the national economy. Clothing expenditures dropped severely during the two recent depression of the national economy. Clothing expenditure dropped severely during the two depression periods. Clothing expenditures were the highest in the fourth quarter and the lowest in the third quarter of the year. 2. According to the results of the regression analysis the business cycles had a significant influence on the clothing expenditures. the volatility of the clothing expenditure was 2.60 times higher than that of the business cycles. 3. Clothing expenditures displayed procyclical fluctuation and coincident movement to the business cycles. Also clothing expenditures showed an unsymmetric behavior over the expansion phases and contraction phases of the business cycles. That is the clothing expenditures increased slowly in the expansion phases and decreased quickly and severely in the contraction phases of the business cycles.

The objective of this study is to analyze the determinants of at-home laver consumption expenditures using the data from a survey of households implemented in 2009. It happened that non-response ratios of monthly expenditures on dry laver and flavored laver among sampled households are 18.8% and 25.6%. Accordingly, this study tries to analyze the determinants affecting at-home laver consumption expenditures by using type II tobit model, one of sample selection models, to deal with sample selection bias caused from non-response data. Analysis results show the age variable positively affects expenditures on dry laver but negatively contributes to expenditures on flavored laver. In addition, the household size, the household's income, the degree of preference for laver have positive relationships with both expenditures. Household size elasticity and income elasticity of the expenditure on dry laver are estimated as 0.220 and 0.251. In the case of flavored laver, these elasticities are estimated as 0.484 and 0.261. Such analysis results can provide information on division of the at-home laver consumption market into groups with high willingness to expense and implementation of detailed marketing strategies to increase at-home laver consumption. The methodology of this study can be applied to consumer preference analysis on other marine products and other analyses on sample with non-response data in the fishery research.

This study was to analyze the effect of private education expenditures on financial performance. The data from 1,669 households were taken from the Korean labor and Income Panel Study. The major findings were as follows: (1) The mean of monthly private education expenditure was 257,400 won for all households. Almost 66% of households encountered an economic burden in paying for private education. (2) The mean of financial performance in all households was 31,420,000 won and those with higher assets showed the greatest financial performance (112.8 million won net gain). (3) The variables that significantly influenced on private education expenditures and the financial performance were different in all households. (4) The relationship between financial performance and private education expenditures was verified partially. The association was proved in the middle assets group.

This study was conducted for the purpose of obtaining basic information on the patterns of medical care expenditures, and identifying some determinants of medical care expenditures in the rural Korea. Nine guns were chosen from the eight provinces, excluding Cheju island. One gun in each province and two villages were selected from the each myon or ub within the selected guns. The total number of households was 1,789 and the sample size was 9,826 non-institutionalized people. Followings are the major findings of the study : 1) Medical care expenditures increase proportionally with age in terms of cost per patient, per episode of illness, per treated case, and per person. Averagely, it cost 2,756 won per patient, 2,614 won per spell of illness, 4,361 won per treated case, and 413 won per person. 2) Medical care expenditures increase proportionally with educational level of patients. College graduates spent the most, 4,726 won per patient, 5,987 won per treated case, and 670 won per person. 3) The male spent a little more than the female in terms of per patient, per episode, and per person. For example, a male spent 23 won more than a female. 4) Those who were suffering from illnesses longer than 1 year spent three times more than that had illnesses of less than 1 year duration. 5) The simple correlation coefficient between activity restriction and medical care expenditures was the highest among others, 0.491. The next was 0.294 between duration of illness and medical care expenditures. 6) Attempts are made to identify the explanatory variables in medical care expenditures. Thirty one per cent of the variances in tile expenditures can be accounted for by the selected 15 predictors. Those predictors belonged to clinical renditions, such as activity restriction, duration of illness, and nature of conditions, are proved to be the most potent independent variabes. Level of education and monthly family income are also significant in terms of beta coefficient. Further studies are called for to unreveal the determinants of medical expenditures.

To analyze the effects of R&D expenditure on the firm value of Korean firms, we classified portfolios based on R&D activity levels. After that, we conducted a time-series analysis to assess excess returns from the portfolios. To carry out such an analysis, an empirical analysis of excess returns in the capital market was performed by using the monthly earning rate of stocks from 2000 to 2013. The purpose of this research is to provide basic data on investment to stakeholders in the capital market by analyzing the effects of R&D on the firm value and to overcome scholarly limitations by offering a new model of analysis. The criteria for classifying the portfolios were based on R&D expenditure levels. The analysis models follow the Fama-French Three-Factor Model and the Carhart Four-Factor Model. The analyses results are as follows. Extrapolating monthly profit rates based on R&D expenditure levels, portfolios with low R&D expenditures showed higher earning rates than those with high R&D expenditures. This suggests that high R&D expenditures did not translate into high earning rates. The investor depreciates the R&D expenditures related profitability and the possibility of success in the market, leading to falls in stock prices and a failure to give a positive effect on the firm value. Our research differs from the previous investigations as we carried out an empirical analysis based on the actual investors' attitudes about R&D expenditures and how these can generate excess earnings. Our research results show that the data related to R&D expenditure are not reflected fully in the market.

The purposes of the present study were (1) to examine the differences between the experienced group in buying foreign-brand formal wear and the non-experienced group in terms of demographic characteristics, clothing expenditures, and purchase behaviors of formal wear, and (2) to investigate the purchase behaviors of and the extent of post-purchase satisfaction to foreign-brand formal wears for purchase group of foreign-brand formal wear. By using questionnaire consisting of 20 questions, data were collected from 754 female consumers in age range of 20~59. Chi-square analysis and t-test were used for data analysis. Significant differences were found between the groups in educational levels, monthly clothing expenditures, monthly household income, the number of formal wear purchased per season, store patronage, items often purchased, perceived proper price per item, and criteria for selecting stores and evaluating products. The group with experiences in purchasing foreign-brand formal wear showed high satisfaction levels with the quality of foreign-brand formal wears. When buying foreign-brand formal wears, the experienced group considered styles and color as important evaluative criteria, and favored stores having sales with wide assortmetsn.

The purpose of this study is to investigate the effects of wife's employment status on the household expenditures of timesaving market substitutes for houseworks. Seven expenditure categories were considered such as food away from home, convenient/prepared food, housing care service, clothing care service, childcare, supplemental education, and domestic services. The data were taken from 1999 Family Expenditure Survey by National Statistical Office. The sample consisted of 29,963 households with 33.2% dual-income households. The average monthly expenditure for food away from home was 127,795 won for dual-income households, while 103.100 won for single-income households. The expenditure for childcare of dual-income households was over six times of single-income households'. Dual-income households spent over ten times of single-income households for domestic services. For most expenditure categories, households with wife working at white-color jobs spent more than other dual-income households. After being other household characteristics to be constant, wife's occupation had found to be related with the household expenditures for most market substitutes. For the expenditures on both food away from home and childcare, employed-wife households with any kind of jobs were found to have higher possibility to spend and to be spent more than non-employed-wife households. The households with wife employed at white-color jobs spent more on clothing care service and domestic services than the households with the not working. Employed-wife households had higher possibility to spend on supplemental education, but they did not spend more on the expenditure, compared to nonemployed-wife households.

Since May 1st in 2008, the products of ginkgo biloba extract have had to be used with the patient's out-of-pocket payment due to reimbursement restriction guidelines. This study aims to analyze the policy effects of reimbursement restriction on pharmaceutical expenditures using interrupted time series(ITS) analysis. We retrieved monthly NHI claims data for the period between May, 2005 and December 2009. The ingredients identified as a substitute for ginkgo biloba have similar indications based on the similar pharmacological activities. The effects of changes in reimbursement scope were evaluated both for all relevant pharmaceuticals within the same therapeutic class and for 2 separate groups : ginkgo biloba's and its substitutes. According to the study results, restrictions on reimbursement scope resulted in savings of the drug expenditures in the targeted therapeutic class. Direct restriction on ginkgo biloba was associated with a decrease in expenditure level by 60.1% and changes in trend from an average increase rate of 1.4% to an average decrease rate of 1.5% for the therapeutic class, with a dramatic decrease in expenditure level(-191.5%) for ginkgo biloba itself, but with an increased expenditure level(+50.1%) and changes in trend from an average increase rate of 2.0% to an average decrease rate of 1.0% for the substitute group. Further policy to restrict nicergoline was associated with additional decrease in expenditure level for the therapeutic class. Additionally, we could identify the balloon effect - a new policy squeezing one part results in bulging out elsewhere. After the restriction of ginkgo biloba, the utilization of and expenditures on its substitutes increased significantly. In conclusion, we demonstrated that consecutively introduced policies effectively reduced overall expenditures on the therapeutic class of interest. Some ingredients played as a substitute while others did not. Further studies need to be conducted to identify which factors determine a substitute.

There are few studies on the characteristics of debtors in individual rehabilitation procedures, though research in this field is needed. The scarcity of research means that public policy and perception are being made with inadequate information and, to a certain extent, based on personal prejudices and misconceptions. The purpose of this study was to find out demographic, economic and psychological characteristics of debtors in individual rehabilitation procedures. For this study, an in-depth interview was used. The major findings were as follows : The focus of this study is debtors in individual rehabilitation procedures. They were all under 40 and received relatively high educations. Interestingly, they showed a high tendency to use debt and an inability to manage their money. They had short time horizons and imperfect self-control in consumption and borrowing decisions. Monthly income, expenditures, asset and debt of the debtors, and monthly payment to creditors were reported. There were a lot of reasons for their bankruptcy : business failure, job loss, the cost of raising children, and expenditures for entertainment causing them to file for individual rehabilitation procedures. One of the major conclusions of this study was the discovery that their psychological characteristics were nearly the same. The implications of the study suggest that financial education and counseling must consider psychological characteristics.
