The purpose of this study is to suggest a research for hotels' expected service quality which influences reservation intention of hotel services. And we checked that these relations are formed by mediating of customer value on the basis of temporal construal theory. The result of our studies is as follows: 1) An abstract hotels' expected service quality(a concrete hotels' expected service quality) influence more on the customer's the social psychological value(the functional value) than the functional value(the social psychological value). 2) The customer's functional value(the social psychological value) influence more on the reservation intention of hotel service near(distant) in time than distant(near) in time. This research provides a theoretical-practical implications to the marketing staffs like packaging designers as well as scholars to study hotel services.

This study attempted to investigate how the effectiveness of value-oriented promotion for media contents depends on self-construal and incorporated Schwartz' value system theory(1992) and Gutman's means-end chain theory(1982) into the development of hypotheses. It was expected that media content promotion emphasizing "openness to change" value would be more appealing to those with independent self-construal, whereas media content promotion emphasizing "conservation" value would be more appealing to those with interdependent self-construal. These hypotheses were generally supported in a series of experiments. Also, the dynamic relationship among the four primary value dimensions proposed by Schwartz (i.e., openness to change, conservation, self-enhancement, self-transcendence) was clearly validated in this study.

This study focus on a economic value of the Big Data technologies by real options model using big data technology company's stock price to determine the price of the economic value of incremental assessed value. For estimating stochastic process of company's stock price by big data technology to extract the incremental shares, Generalized Moments Method (GMM) are used. Option value for Black-Scholes partial differential equation was derived, in which finite difference numerical methods to obtain the Big Data technology was introduced to estimate the economic value. As a result, a option value of big data technology investment is 38.5 billion under assumption which investment cost is 50 million won and time value is a about 1 million, respectively. Thus, introduction of big data technology to create a substantial effect on corporate profits, is valuable and there are an effects on the additional time value. Sensitivity analysis of lower underlying asset value appear decreased options value and the lower investment cost showed increased options value. A volatility are not sensitive on the option value due to the big data technological characteristics which are low stock volatility and introduction periods.

The recent economic recession and price rise reduces excessive consumption as a whole. So companies take more interest in and use discount coupons as a means of sales promotion to reinforce their competitiveness. The combination of Internet and mobile communication technology leads to an explosive increase in the use of mobile Internet service, which promotes commercialization of mobile coupons. Nevertheless, there are absolutely insufficient researches on mobile coupons than those on paper ones. In this context, this study tries to consider intention of accepting and using mobile coupons. The innovated Technology Acceptance Model (TAM) was used to see factors of using mobile coupons considered important by customers. Through the combination of characteristics of mobile coupon service and values obtained from mobile coupons, effects of variables to enhance intention of using mobile coupons were empirically analyzed. In particular, this study suggested importance of psychological as well as economic values of mobile coupons and emphasized good considerations of the psychological aspect, such as shame, stinginess, and reputation sensitivity, in using mobile coupons as an important factor for intention of using the coupons. Another empirical analysis was made of what moderating roles consumers' self-construalplayed in the effects of mobile coupon values perceived by consumers on intention of using coupons. As a result, immediate connectivity and situational provision among characteristics of mobile coupon service were found to affect ease and usability. It was also shown that perceived ease and usability had significant effects on both economic and psychological values, which then had significant effects on intention of using a mobile system. After testing moderating effects of self-construal, the degree of effects of perceived mobile coupon values on intention of using mobile coupons was greater among inter-dependent self-construal users than among independent ones. This study considered various schemes of improving intention to use mobile coupons and provided a foundation to help companies make a strategy for mobile coupons to be activated in the future.

본 논문은 조건부가치측정법(CVM)의 적용에 있어 발생할 수 있는 비구분 효과에 대한 검증과 해석을 제시하고 있다. 한강과 한강을 포함한 4대강의 수질증가에 대한 편익을 조건부가치측정법을 이용하여 추정하고 이 과정에서 비구분효과의 발생 원인을 분석하고 있다. 본 논문에서는 비구분효과의 발생 가설로 대체효과 뿐만 아니라 새로운 가설인 순편익효과를 설정하였다. 연구결과는 대체효과 뿐만 아니라 본 논문에서 세운 새로운 가설인 순편익효과가 비구분효과의 원인으로 크게 나타났다. 본 연구 결과로 볼 때 비구분효과가 조건부가치측정법의 자체적 한계라기 보다는 설문의 구성 및 과정상의 문제임을 제시하고 있다.

We test the hypothesis whether foreign direct investments(hereafter "FDI") can affect the changes of the firm value. In this study, we use a newly developed event study technique, referred to as value-based event study approach(hereafter "VESA"), which is based on the seminal papers of M&M(1958, 1961, 1963) and Lee(2006, 2007). The empirical findings about the effects of FDI's on the intrinsic firm values, which can be measured by intrinsic Q(hereafter "IQ") values of the VESA, are as follows; First, the FDI's are carried out by healthy firms in terms of high IQ's. The IQ values become higher during the post-FDI period than prior to performing FDI's. Second, among the four components of IQ values, the value of assets-in-place, the value of intangible assets, and the value of growth opportunities are all increased during the post-FDI period, except the value of current earnings. Third, the same results are observed in all the samples classified by industry. In sum, thanks to the above findings in this study, we can conclude that the announcements of the FDI's are good and reliable indicators for the firm to signal to the market that the FDI firms are healthy in intrinsic firm values, and also that they have good chances to increase their firm values through the new investments abroad.

오늘날 다양해지는 산업구조에서 가장 핵심적인 분야로 떠오르고 있는 서비스는 국가의 미래전략사업으로 현재 각 국가들은 서비스를 중요한 이슈로 타 학문과의 연계 가능성에 대한 연구가 진행되고 있다. 서비스란 국가의 생활환경과 문화 수준에 따라 현저한 차이를 보이고 있지만 신 개념의 서비스는 접근방법에 있어서 소비자가 원하는 요구조건을 개인의 특성에 맞는 맞춤형서비스라는 공통된 방식으로 진행되고 있다. 동양에서의 서비스란 단순히 무료로 가치를 보상받지 않고 육체적, 물리적 가치를 상대에게 제공한다는 의미로 해석되고 있는 반면, 서양에서 서비스 개념은 가치를 제공함 으로서 합당한 대가를 돌려받는다는 의미로 해석된다. 이러한 서비스의 개념은 디자인을 서비스라는 시각에서 볼 때 소비자에게 가치의 제공이라는 개념으로 지금까지 많은 기업 및 산업체에서는 디자인을 실시하는 행위가 소비자를 위한 서비스 제공이라는 개념으로 생각하지만 실제 디자인에서 서비스 접근방법은 명확한 기준과 근거가 부족한 편이다. 따라서 본 연구에서는 기존 연구에서 밝혀진 부산 관광자원의 중요 요소인 쇼핑환경을 개선하기 위해 소비자의 이용 빈도가 높은 부산시 마트(Mart)를 중심으로 이용자에게 좀더 편리한 쇼핑환경을 제공하기 위한서비스디자인 방법을 연구하고자 한다. 연구방법에 있어서는 실제 마트(Mart)를 이용하는 소비자의 심리분석과 문제점, 행동분석을 통해 쇼핑환경을 개선하고 이용자에게 편리한 제품디자인 방법을 연구하여 마트(Mart)의 서비스 디자인 방법을 찾아본다.

한국의 옵션시장은 1997년 7월 7일부터 시작되었다. 이후로 시장 규모는 가파르게 성장하였으며 최근에는 하루 평균 거래대금이 1조원에 이른다. 시장을 예측하는 것은 불가능하다. 하지만 통계적 특성을 이용하면 지속적인 수익을 얻을 수 있다. 지수선물의 미결제약정은 장시작 시간인 9시부터 증가하기 시작하여 정오 근방에 최대 약 4000 계약 너머까지 증가하고, 다시 하락하기 시작하여 장 종료 시간인 15시에는 장시작시의 미결재약정으로 환원되는 특성이 있다. 이러한 특성을 변동성과 연관지어 해석하고 시간기반의 간단한 전략을 적용하면 하루에 약 1.07%의 수익을 얻을 수 있다. 이 때 8번의 거래가 발생하고 매매수수료를 제외하고 순이익을 얻기 위해서는 수수료가 저렴한 증권사를 찾아야 한다. 미결제약정의 특징을 변동성으로 해석할 수도 있지만 본 논문에서는 새로운 방식인 변동속도로 해석한다. 옵션의 가격은 내재가치와 시간가치로 이루어진다. 통계적으로 지수가 하락하는 속도가 상승하는 속도보다 빠르므로, 풋옵션의 변동성은 콜옵션의 변동성보다 통계적으로 크다. 이러한 속도 특성을 활용하면 0.15%에 이르는 매매 수수료를 제외하더라도 하루에 약 1.4%의 수익을 얻을 수 있다.
