공공투자사업평가 시 사회적할인율의 높고 낮음에 따라 비용 편익분석의 결과가 상이하다는 점에서 적정 수치는 매우 중요한 요소이다. 그리고 사회적할인율의 개념을 무엇으로 적용하는 것이 합리적인지에 대한 많은 논란과 연구가 현재까지 진행되고 있다. 본 연구에서는 사회적할인율의 개념을 크게 세 가지 사회적 시간선호율, 사회적 투자수익률 그리고 이 둘을 가중평균 한 값으로 구분하였다. 추정방법으로는 사회적 시간선호율의 경우 소비이자율과 Pearce and Ulph식을 사용하였고, 사회적 투자수익률은 민간 총 자본 수익률을 사용하였다. 그리고 가중평균은 투자의 잠재가격을 이용한 Squire, L., Herman G. van der Tak식과 공공투자와 대치되는 민간투자와 민간 소비지출비율을 이용하여 추정하였다. 본 연구에서는 현재 시점의 사회적할인율을 추정하기 위해 연대구분을 1990년대, 2000년~2003년, 2004년~2008년으로 각각 구분한 후, 과거 한국개발연구원에서 제시된 1999년 7.5%, 2004년 6.5%, 그리고 2007년~현재 5.5%와 각각 비교하였다. 추정결과는 1990년대 6.6~10.7%, 2000년~2003년 4.0~7.0%, 2004년~2008년 2.4~3.9%로 각각 추정되었다. 현재 공공투자 사업평가에 사용되고 있는 사회적할인율 5.5%는 본 연구의 추정결과 보다 약1.6~3.1% 높은 것으로 나타났다. IMF이후 급격하게 하락한 소비이자율은 계속적으로 낮아지고 있고 앞으로도 지속될 것으로 예측하고 있다. 따라서 공공투자 사업의 목적인 현 세대부터 장래세대까지 모두를 고려한 사회적 자원의 재분배를 실현시키기 위해 선 현재의 사회적할인율은 점차 하향조정할 필요가 있다.

Based on increased popularity and use of social network services as a marketing tool, social commerce became an emerging trend in e-commerce platforms. Social commerce involves sellers offering potential consumers the products and services at a lower price in a limited time period. Through comparison of the performances of domestic social commerce websites, we found that the buying environment such as price, number of available products, and the remaining time period for sale has a significant difference influencing on the purchase decisions of consumers. This study aims to analyze the interaction effects and preference levels of four characteristics (price, discount rate, number of purchases and purchase time) by conducting choice-based conjoint analysis. Survey experiment was performed using a sample of 146 undergraduate and graduate students. The results showed that consumers importantly consider purchase time, discount rate, price, number of purchases in the order of their preference. Also, discount effect is more significant on purchase decisions than price effect and consumers distinguish less the differences among the buying environment characteristics in the closing days of purchase period. Customer segmentation using the preference levels of characteristics indicates that the preference levels have different effects in the purchase utility of each segment. The proposed customer segmentation and differences in feature utilities are expected to be valuable in forming future sales promotion strategies in social commerce.

This study investigates the perception of price and the propensity to conspicuous consumption in the purchase of clothing among college students and the relation between the perception of price and the propensity to conspicuous consumption. The data for this study were collected from 1,015 Korean college students. In order to analyze the data, statistical methods such as frequency, percentage, mean, standard deviation, factor analysis, ANOVA, scheffe-test, Pearson's correlation, and Cronbach's a were used with the SPSS statistical package program. The major study findings were as follows. 1. The perception of clothing price among college students was classified into five factors: high price-oriented, discount-oriented, high quality-price rate-oriented, low price-oriented, and effectiveness-oriented. 2. The propensity to conspicuous consumption of clothing among college students was classified into four factors: brand name conspicuousness, conspicuous pursuit of vogue, symbol of their social position, and imported goods conspicuousness. 3. High price-oriented and discount-oriented were different significantly according to sex, age, father's educational level, monthly income, monthly allowance amount. High quality-price rate-oriented and low price-oriented were different significantly according to sex, father's educational level, monthly income, monthly allowance amount. Effectiveness-oriented was different significantly according to sex, age. 4. Brand name conspicuousness, conspicuous pursuit of vogue and imported goods conspicuousness were different significantly according to sex, age, father's educational level, monthly income, monthly allowance amount. Symbol of their social position was different significantly according to sex, age, father's educational level, monthly income. 5. High price-oriented, discount-oriented and high quality-price rate-oriented have the highly positive correlation with four factor of propensity to conspicuous consumption of clothing. Low price-oriented has the negative correlation with four factor of propensity to conspicuous consumption of clothing. Effectiveness-oriented has the lowly positive correlation with four factor of propensity to conspicuous consumption of clothing.

It is estimated that there is a total of approximately 100,000 species in Korea. However, the number is currently about 30,000 and only 16,027 species are listed in the 'Species Korea' (as of December, 2014). Of the listed species, 51 species are designated as the Endangered Species Class I while 195 species are in the Class II, totaling 246 endangered species including 20 mammals. Under the circumstances that development (e.g., roads) is increasingly threatening the persistence of endangered mammals, it is significant to identify and preserve suitable habitats for them. In this context, evaluating the values of the suitable habitat environment would serve as essential information for development decision making. This study estimated the values of endangered mammals' forest habitats through spatialization of habitat services. In doing so, a species distribution model, Maximum Entropy Model (MaxEnt) was utilized for a group of endangered mammals including, mountain goat, wildcat, marten cat, and flying squirrel. To calculate the values per unit area, a benefit transfer method was used based on the point-estimate technique with the best available values estimated previously. The range of discount rate of 3.0 to 5.5 percent was applied taking the notion of social discount rate into account. As a result, the province with the highest values for endangered mammal habitats appeared to be Gangwon, followed by Gyeongbuk and Gyeongnam. The monetary values of the endangered mammal habitats were estimated to be 330 billion to 421 billion won per year.

The purpose of this study is to evaluate the feasibility of the new marine leisure ships. In order to achieve the research purpose, the cost and income were calculated based on the operating of other marine leisure ships, and the feasibility of the project was empirically analyzed. This study established a research model that applies the values derived by empirically analyzing ships with similar specifications, to the new marine leisure ships. We then calculated the cost-benefit analysis, net present value, and internal return, and evaluated the feasibility of the project based on this. As a result of the business feasibility analysis of investing in marine leisure ship, it was found that economic feasibility exists with a B/C of 1.042 and 1.049 for new and secondhand ships, respectively; however, considering the stability of the ship and the publicity and continuity of the business operation, it is recommended to invest in new ships compared to secondhand ships. The total benefit over the 10-year operating period using a social discount rate of 4.5% was evaluated to be about KRW 292.0 billion, which is higher than the total cost of KRW 256.6 billion. In conclusion, the profitability analysis showed that the B/C was 1.042, the NPV was KRW 193 billion, and the IRR was 2.1%, which indicates that profitability is weakly secured.

Objectives : The aim of the study was to estimate the annual socioeconomic cost of diseases in Korea. Methods : We estimate both the direct and indirect costs of diseases in Korea during 2003 using a prevalence-based approach. The direct cost estimates included medical expenditures, traffic costs and caregiver's cost, and the indirect costs, representing the loss of production, included lost workdays due to illness and lost earnings due to premature death, which were estimated based on the human capital theory. The cost estimates were reported at three different discount rates (0, 3 and 5%). Results : The cost of diseases in Korea during 2003 was 38.4 trillion won based on 0% discount rate. This estimate represents approximately 5.3% of GDP The direct and indirect costs were estimated to be 22.5 trillion (58.5% of total cost) and 15.9 trillion won (41.5%), respectively. It was also found that the cost for those aged $40\sim49$ accounted for the largest proportion (21.7%) in relation to age groups. The cost of diseases for males was 23.5% higher than that for females. For major diseases, the total socioeconomic costs were 16.0, 13.4, 11.3 and 11.19% for neoplasms, and diseases of the digestive, respiratory and circulatory systems, respectively. Conclusions : This study can be expected to provide valuable information for determining intervention and funding priorities, and for planning health policies.

The study attempts to estimate and evaluate the rates of return on graduate degree holders who major in science and engineering. The model of this study adopts the rate of return method considering unemployment as well as mortality rate. The data are collected by questionnaires and interviews. The results show that the social rate of return(SROR) of bachelors is lower than the rate of return on investment in physical capital which is assumed as a decision criterion of public investment in Korea, but the SROR of Ph.D. holders is balanced. The results also show that the private rates of return (PROR) of all the levels in postgraduate science and engineering education are higher than the private discount rate which is a decision criterion of private investment in Korea. It also indicates that the PROR on investment in graduate education is not likely higher than the SROR because an individual bears high share of the educational costs.

Social commerce is regarded as a kind of e-commerce that utilizes social media. Considering increasing complaints around social commerce market, it is important to see customers' satisfaction level and intentions to repurchase. In this study, we examine antecedents that affect customers' satisfaction and relationship between satisfaction and intention to repurchase in social commerce market. We also use social media characteristics as moderators between antecedents and customers' satisfaction. The main results are as follows. First, except site design, most of the intrinsic factors of service quality, such as information, transaction, communication and perceived security had positive effects on customers' satisfaction. Second, all the extrinsic factors of service quality, such as discount rate, constraints, and discrimination had significant impacts on customers' satisfaction. Third, the social media characteristics could not moderate the relationship between service qualities and customers' satisfaction. Fourth, customers' satisfaction had positive effect on the intention to spread through social media. Fifth, customers' satisfaction had positive effect on the intention to repurchase. Social commerce companies need to set up strategies considering the antecedents of customers' satisfaction using these research results. They also need to secure customers that have sustainable purchasing intentions.
