포스트 교토체제에서는 A/R CDM 등 산림 분야의 중요성이 증대할 것으로 전망된다. A/R CDM에 대한 정확한 경제성 평가는 투자의사결정에 유용한 정보를 제공하여 투자 활성화로 이어질 수 있다. 본 연구에서는 전통적 경제성 평가 방법이 간과한 의사결정자의 의사결정권의 가치 내지 기다림의 가치를 반영한 실물옵션 방법에 의해 모형을 구축하고 실제 A/R CDM 사례를 적용하여 실증분석을 하였다. 그 결과 적용 사례의 경우 최적투자분기점이 추정된 l-CER의 가격보다 낮게 나타남으로써 적절한 투자의사결정이 이루어졌음을 알 수 있었다. 그러나 할인율의 수준과 적용 범위에 따라 최적투자분기점과 투자의사결정이 크게 영향을 받는 것으로 나타났다.

The purpose of this study was to examine how much the cost of marriage ceremony has increased according to the economic growth. The relationship between marriage expenditures and other comparison variables such as per capital GNP, monthly income, consumer price index was particularly examined. All the money values were adjusted by consumer price index. Data from the Central Committee for Promotion of Saving were used in this study. The results of this study follow. First, nominal and actual total outlay of marriage ceremony has continuously increased. Total marriage ceremony cost was positively correlated with the housing price so that bridegroom’s outlay were greater than that of bride’s one since bridegroom was more likely to have the responsibility for the price of new couple’s house. Second, it was found that increased percentage rate of marriage ceremony cost was greater than that of national economic growth. The total marriage expenditure was about 10 times as much per capital income in 1990. Third, it was revealed that housing cost increased three times from 1990 to 1995, and marriage ceremony expense was accordingly increased twice during the same periods. Such trends tend to increase continuously. Last, the marriage cost percentage to monthly income called marriage expenditure share increased by 1990 and then decreased. Such a decreasing trend can be explained by the increased amount of income partly due to the higher wage rate compared to other conditions since 1990.

This study examined whether and how consumers who seek a bargain in their shopping for luxury fashion brands differ from traditional luxury consumers or non-luxury consumers on their market-related attitudes. To do so, this study compared multi-dimensional perceived values, fairness price perceptions, satisfaction with purchase, brand loyalty, and future purchase intention among luxury consumers, luxury-bargain seekers, and non-luxury consumers. Data was obtained from online surveys and the market-related attitudes were compared using an ANOVA test. The comparion of three types of consumers revealed that luxury-bargain seekers and regular luxury consumers are distinct consumer markets. Overall, luxury consumers displayed high perceived values and brand loyalty and were fairly satisfied with the purchase at full-prices. On the other hand, luxury-bargain seekers showed significantly low perceived social value, perceived fairness toward the original price of the brands, and brand loyalty. They were satisfied with the bargain purchase but not likely to purchase the luxury at full-prices in the future. Understanding these distinct types of consumers and targeting them with different product and pricing strategies are important for luxury brands and retailers to expand luxury consumer base without diluting their brands' prestige image. Potential marketing strategies based on the findings of this study were suggested.

게임 산업의 성장에 따라 관련 업체들은 게임 판매량과 이익 증진을 위해서 가격할인 프로모션을 진행한다. 이러한 가격할인 프로모션은 소비자들이 게임과 같은 쾌락을 목적으로 제품을 할 때 그들의 죄책감을 줄여주는 정당성을 부여할 수 있어 높은 효과를 보인다고 하였다. 하지만 온라인 멀티게임의 발전으로 인하여 많은 소비자들은 온라인 상에서 타인과 사회적으로 연결될 수 있고 이러한 사회적 연결은 소비자들에게 실질적인 이익을 제공할 수 있기에 게임을 쾌락재로만 한정적으로 볼 수 없다. 따라서 본 연구에서는 사회적 관계 유무에 따라 게임을 종류를 분류하여 가격할인 효과에 대해서 알아보았다. 본 연구에서는 Steam이라는 세계적인 게임 플랫폼 회사를 대상으로 데이터를 수집하여 가격할인 게임 이용자 수에 미치는 영향에 대해서 알아보았으며, 그 결과 가격할인 효과의 차이를 밝혔다. 본 연구에서는 분석결과를 바탕으로 게임 실무자들에게 효과적인 프로모션 방안에서 대해서 제안한다.

Objectives: This study evaluated nutritional quality of convenience store meal boxes according to store company and meal price. Methods: In May 2020, 71 meal boxes from five major convenience store companies were collected. Respective weights of all dishes and food ingredients included in each meal box were measured with a digital scale. Information on nutritional contents was collected from nutrition fact panels on packages. Food group patterns, dietary diversity scores (DDS), and dietary variety scores (DVS) were analyzed. Nutritional contents, i.e., amounts of energy, protein, and sodium, and percentages of energy from carbohydrate, sugar, fat, and saturated fat were compared with respective standards based on the 2020 Dietary Reference Intakes for Koreans. Comparison was made among five companies (Company A, B, C, D, E) and three price groups (≦ 4,200 won, ≧ 4,300 and ≦ 4,500 won, ≧ 4,600 won). Multiple regression analyses were conducted to examine the difference of nutritional contents according to company and price, respectively while holding the other variable constant. Results: DDS, but not DVS, significantly differed among companies. The percentages of meal boxes meeting the nutritional standards of sodium significantly differed among companies; the percentage was highest in companies B (75.0%) and C (73.3%). "Company" was associated with amount of energy, protein, and sodium, and percentage of energy from saturated fat. "Price" was associated with the amount of energy and percentage of energy from carbohydrate. The average number of satisfied standards was highest in companies B (5.0) and C (4.0). About two-thirds of the meal boxes provided less amount of energy than the standard; the percentage of such meal boxes was highest in meal boxes with price of 4,200 won or lower. Conclusions: There were significant differences in the nutritional quality of meal boxes according to "company". Meanwhile, higher-priced meal boxes did not necessarily ensure better nutritional quality.

The purpose of this study is to compare short-term price predictive power among ARMA ARMAX and VAR forecasting models based on the MDM test using monthly consumer price data of frozen mackerel. This study also aims to help policymakers and economic actors make reasonable choices in the market on monthly consumer price of frozen mackerel. To analyze this study, the frozen wholesale prices and new consumer prices were used as variables while the price time series data were used from December 2013 to July 2021. Through the unit root test, it was confirmed that the time series variables employed in the models were stable while the level variables were used for analysis. As a result of conducting information standards and Granger causality tests, it was found that the wholesale prices and fresh consumer prices from the previous month have affected the frozen consumer prices. Then, the model with the highest predictive power was selected by RMSE, RMSPE, MAE, MAPE, and Theil's inequality coefficient criteria where the predictive power was compared by the MDM test in order to examine which model is superior. As a result of the analysis, ARMAX(1,1) with the frozen wholesale, ARMAX(1,1) with the fresh consumer model and VAR model were selected. Through the five criteria and MDM tests, the VAR model was selected as the superior model in predicting the monthly consumer price of frozen mackerel.
