The paper aims to estimate the external effects of mountaineering on medical expenses within national economy. Though there is no difference in the participation ratio of mountaineering among sexes or income levels, the ratio of the elderly is higher than that of younger. The medical expenses have negative correlation with mountain climbing times and climbing frequencies, but this correlation is insignificant statistically. Without mountaineering, the medical expenses of Korea would increase by 2.8 trillion Won (4.6%). Therefore the policy to support usual mountaineering must save the medical expenses more than other policies. and the increase of public expenditure on mountaineering can decrease the deficit of government budget through the positive external effects on national medical expenses.

The purpose of thin paper is to test difference of the two question formats, open-ended and dichotomous choice formats, in the contingent valuation method using the estimated recreational benefits. The data were collected from the visitors at the Songnisan National Park. The recreational benefit based on the equivalent variation. The two question formats, but the same content, were asked of the same individuals. In this analysis, it was used travel cost and monthly income as the exogenous variables, which assumed a linear functional form for the WTP equation. The model assumed a bivariate normal distribution on the basis of the probit and tobit model concerning the censored zero WTP. The result showed no differences in the recreational benefits from the different question formats under a same respondent. The mean benefit was estimated 25.556 Won per 5 years per visitors.

This study explores the general marketing ethics among Koreans and helps us understand bu such as bribery, unfair price increases, and so on. By examining msiness ethics in Korea. Based on a scenario approach, we focus on the ethical problems developed or identified from previous research in the western countries. We find that the people in our sample perceive the relative seriousness of ethics problemsarketing-related ethical issues, first we find the differences in how the young and old recognize business ethics. Specifically the younger generation in Korea shows less ethical reaction in general because they have not developed a long-term perspective. Moreover the older generation shows less ethical attitude towards bribery. Second, we confirm the findings in Zey-Ferrell et al (1991) that all individuals think they are more ethical than others. We also discuss other demographic variables related issues that might affect the business ethics in Korea.

The aim of this study is to identify the influence of public housing on depression of its residents by analyzing the 7th Korea welfare panel study. To reduce the selection bias which arise from the public housing is selected by personal choice, we used PSM(propensity score matching). In addition, we merged the result of PSM and OLS regression to control the other variables which can affect depression of the resident of public housing. Final result revealed that the statistical significance which was observed when we compared the level of depression between the residents of public housing and general community by independent t-test was not observed when we used the merged result from PSM and regression. These results suggest that the high level of depression in the residents of public housing might be related with their demographic characteristics or earned income not with the public housing itself. This study can be the evidence supporting the policy of providing public housing because living in public housing did not give negative influence on its residents. Considering that this study also showed that there were no observable positive influences of public housing, we can suggest that public housing policy for majority of people not limited to people with low income.

OECD countries have been stimulating private pensions instead of public pensions because the financial stability of public pensions has been threatened by the aging population. Korea, which has the fastest aging population in the world, has been following the recommended policies of major countries. Unlike major economies, however, most of Korea's household assets are composed of real estate assets. Due to the economic and social importance of real estate assets in Korea, the wealth effect of real estate has been used as a major tool in macroeconomic policy. This study analyzed the effect of real estate value changes on the contribution of private pensions (personal pension + retirement pension). Utilizing a two-way, fixed effect model with the balanced panel data of the National Survey of Tax and Benefit, empirical results presented that the private pension contribution increased by 0.171% when the value of real estate increased by 1%. Thus, real estate value changes were analyzed as positive for retirement preparation through private pension. These results suggested that if the real estate market would shrink in the future, consumption would decrease, and the degree of preparation for retirement might be smaller.
