This study reviewed the consumption patterns of high-income households and analyzed the ratio of major 6 expenditure categories including food at home, food away from horne, education, clothing, entertainment, and housing expenditure to total expenditure. We employed data from two different years (1997 and 1998) so that we could investigate the influence of the economy depression on the patterns and items ratio of consumption, For this purpose, the Daewoo Panel data were used. Also, data analysis was done with descriptive statistics, t-test, and regression analysis. The regression analyses were used to investigate the determinants of the high-income households' consumption patterns. The results of this study showed that food away from home, among 6 consumption items, seemed to be significantly affected by the depression, but still high-income households seemed not to lessen education expense. We included independent variables such as age, income, job, gender, debts and the likes. It was found that the age of reference person affected the amount of expenses for food, clothing, and entertainment. Other independent variables influenced different consumption categories. The results of this study would be useful for marketing strategies of fashion industries.

Global research and development (R&D) spending has increased in recent years as the need for new technologies has grown and structural changes in the market have become evident. R&D and its transfer into the commercial sector have an important relationship. This paper analyzes the relationship between industrial R&D expenditure and how it affects technology transfer in Malaysia, Singapore and Taiwan. The research is based on the analysis of secondary data from published annual reports followed by a quantitative analysis of primary data using survey questionnaires. The research finds that the bulk of R&D expenditure was from the top ten organizations and the top five industries for each country. The findings also reveal that an organization's readiness in terms of technology and people capabilities is still weak in Malaysia and Singapore. The findings also indicate that there is a relationship between industrial R&D expenditure and the propensity of technology transfer in Taiwan.

This study is to investigate the determinants of consumption expenditure by considering potential expenditure factors such as socioeconomic, fishing village tourism behavior, motivation for visits, and optional attributes of tourists at Muchangpo webfoot octopus and finespotted flounder festival in Boryeong. The analysis data are 300 questionnaires of visitors to the festival during the 2018 Muchangpo Mysterious Sea Road Webfoot Octopus and Finespotted Flounder Festival from March 17 to April 8, 2018. As a result of analyzing the factors of consumption expenditure of tourists to the festival in Boryeong, socioeconomic factors such as gender and residential groups outside Chungcheong-do have a positive (+) effect on consumption expenditure. Among the factors of fishing village tourism behavior, the only number of days of stay more than one night has a positive (+) effect on consumption expenditure. In addition, in the analysis of factors for motivation to visit the festival, fun/interest and simple rest/leisure have a significant positive (+) effect on expenditure whereas stress relief have a negative (-) effect on expenditure. In the analysis of the factors of festival selection attributes, tourism facilities has a significant positive (+) effect on expenditure, but natural scenery and excellent natural scenery show a significant negative (-) effect on expenditure. The main implications that can be obtained from the results of this study are as follows. First, it suggests that the promotion should be actively conducted outside of Chungcheong Province in order to achieve the original purpose of revitalizing the local economy from the Muchangpo webfoot octopus and finespotted flounder festival. Second, it indicates that there should be a variety of unique high-quality festival programs differentiated from other local festivals, promoting the existence of simple rest/leisure facilities rather than webfoot octopus boat fishing experiences or natural scenery (i.e., mysterious road and sunset) in order to attract festival tourists' spending at the Muchangpo webfoot octopus and finespotted flounder festival.

In insurance, the surrender rate is an important variable that threatens the sustainability of insurers and determines the profitability of the contract. Unlike other actuarial assumptions that determine the cash flow of an insurance contract, however, it is characterized by endogenous variables such as people's economic, social, and subjective decisions. Therefore, a microscopic approach is required to identify and analyze the factors that determine the lapse rate. Specifically, micro-level characteristics including the individual, demographic, microeconomic, and household characteristics of policyholders are necessary for the analysis. In this study, we select panel survey data of Korean Retirement Income Study (KReIS) with many diverse dimensions to determine which variables have a decisive effect on the lapse and apply the lasso regularized regression model to analyze it empirically. As the data contain many missing values, they are imputed using the random forest method. Among the household variables, we find that the non-existence of old dependents, the existence of young dependents, and employed family members increase the surrender rate. Among the individual variables, divorce, non-urban residential areas, apartment type of housing, non-ownership of homes, and bad relationship with siblings increase the lapse rate. Finally, among the financial variables, low income, low expenditure, the existence of children that incur child care expenditure, not expecting to bequest from spouse, not holding public health insurance, and expecting to benefit from a retirement pension increase the lapse rate. Some of these findings are consistent with those in the literature.

The purpose of a national health care system is to improve health care outcome among population. The objective of the study was to explore the determinants of health outcome in the 24 OECD countries between two health care financing systems. The study employed the pooled time series and cross-sectional analysis with tax-funded and social insurance-funded countries over the period of 1980 to 1999 using OECD Health Data 2002. The study revealed that health expenditure per capita, physicians per 1,000 of the population and calorie intake were positively significantly associated, smoking rate was negatively associated with health outcome while controlling all variables in the tax-funded countries. But in the insurance-funded countries, health expenditure per capita and the number of physicians were not statistically significant factors explaining health outcome. Only the calorie intake was positively associated with, and smoking rate, alcohol consumption per capita, and total nitrogen oxide emission per capita were negatively significantly associated with health outcome. In conclusion, healthy life style factors were much more important to improve health outcome in the both systems.

This study was conducted in order to assess the effect of variables influencing Korean baby-boomers' welfare consciousness. For this purpose, data from the $8^{th}$ supplementary survey of the Korea Welfare Panel in 2013 were analyzed. The subjects of analysis were 2,035 people who were born between 1955 and 1965 whose welfare panel data did not have missing values for the variables of the research model. According to the results of analysis, first, when the descriptive statistics of the major variables were analyzed, those showing a relatively high mean score among the sub-factors of the baby-boomers' welfare consciousness were 'expansion of expenditure for public assistance' (mean 3.65, SD .557), 'expansion of expenditure for social insurance' (mean 3.53, SD .646), and 'expansion of expenditure for social services' (mean 3.26, SD .424). The mean score of the baby-boomers' overall welfare consciousness was relatively high as 3.45 (SD .428), advocating the expansion of welfare expenditure. Second, the independent variables influencing the baby-boomers' welfare consciousness was found to have explanatory power of 12.9%. In the results of regression analysis, variables found to have a significant effect were gender (B=.100, t=2.573, p<.01), personal responsibility for poverty (B=-.151, t=-3.635, p<.01), social responsibility for poverty (B=.149, t=3.437, p<.001), and recipient's laziness (B=.251, t=6.578, p<.001). Based on these results were discussed major relevant policies.

This study analyzes Korea health panel data (2008) (beta version 1.2) of Korea Institute for Health and Social Affairs, and National Health Insurance Corporation to figure out determinants of healthcare expenditure. In result of Multiple Logistic Analysis, in-patents felt burden on the medical expenditure were 70.0%. As to the patients' payment of medical expenditure, patients over 65 years old had 4.765 times higher than those under 14 years, disabled patients 2.778 than non-disabled patients, chronic patients 1.632 times than non-chronic patients, patients belonging to 12 million won ~ 46 million won and under 12 million won in family income had 1.680 times and 2.168 times respectively than patients with over 46 million won, patients in professional recuperation facility 1.546 times than patients in hospital, patients in private medical institutions 1.700 times than patients in national and public medical institutions, patients using upper grade rooms 1.701 times than patients in non-upper grade rooms. As a health care safety net mechanism to protect people from medical expenditure burden, there is the patients' payment ceiling in the National Health Insurance System. Thus, in order to facilitate the patient's payment ceiling, it is required that the level of ceiling is to be specified according to the income level, and self-payment items is to be included.

The main purpose of this study is to analyze the determinants of innovation in the medium core firms that belong to components and materials industry. For this purpose, we introduce the Schumpeterian hypothesis as a theoretical background at first. According to the Schumpeterian hypothesis, large firms in concentrated markets are likely to have more innovative activities. That means, firm site and market structure are the main determinant of innovation. Then, we propose other economic factors that have been considered to have effects on firms' innovative activities in previous studies. Those factors are export, profit, growth rate, R&D expenditure and capital intensity. In order to analyze the determinants of innovation, we estimate whether firm size, market structure, export, profit, growth rate, R&D expenditure and capital intensity affect to the possibility of creating innovation in medium core firms. In order to do this, our study uses survey data from 'Korean Innovation Survey(2005)' conducted by STEPI as well as utilizes the probit model as an analytical method. According to the empirical results, firm size has a positive relationship with innovative activities of medium core firms but market concentration does not. We find the negative correlation between market concentration and innovative activities in this study. Thus, was have to say that we do not fully support the Schumpeterian hypothesis in this case. Among other variables, profit and R&D expenditure are estimated to have positive relationship with innovative activities, while export and capital intensity are estimated to have negative relationship with innovative activities. In case of growth rate, we do not find any significant relationship with innovative activities. In conclusion, larger firm size, higher market competition, more access to the financial market and additional R&D investment would facilitate innovative activities of medium core firms. However, we have to review the relationship between export and innovative activities that has been estimated in this study. While the estimated effect of export on innovative activities can be explained by the own characteristics of medium core firms that produce and supply capital goods to final manufacturer, we have address this issue in the future.

Background: The use of therapeutic materials based on new health technology has increased in recent years in the field of medicine, raising concerns for medical practitioners regarding increased spending on the new therapeutic materials amid the rapid population ageing and increase of chronic diseases in Korea. While therapeutic materials have significant importance in the health care system, they have not been given appropriate attention in the academic world of Korea. The purpose of this study is to identify factors that affect the growth of expenditure on therapeutic materials and to derive implications for an effective management considering the diversity of therapeutic materials. Methods: Using the claims data of the National Health Insurance Services, specific utilization patterns of groups of therapeutic materials in the middle classification level of Health Insurance Review and Assessment Service from 2007 to 2014 were analyzed. Four categories (J5083: drug eluting coronary stent, D0302: nonmetallic anchor, K6014: gauze, K6023: gauze) that exhibit unique patterns with respect to price and volume were selected. Then, decomposition analysis was performed to identify the largest contributor to the spending growth by dividing the products into existing, new, and abandoned products for the period between 2010 and 2013. Results: The effect of new products had larger impact on spending growth than the effect of core items in drug eluting coronary stent (J5083) and nonmetallic anchor (D0302). In addition, existing products in general included items priced relatively lower when compared with another item manufactured by the same company. In the gauze category, however, existing products had the largest impact on expenditure and the effect of volume was greater than that in other categories. Conclusion: This study provides evidence that appropriate management measures classified by the characteristics of therapeutic materials are required for therapeutic materials pricing and reassessment in Korea.
