The objective of this paper is to quantify economic values of parcel service attributes (safety, reliability, quickness, and kindness and customer service) using the contingent choice method and to investigate impact factors (such as sex, age, and education), which influence choice of desirable parcel services. As empirical results, the marginal willingness-to-pay for multiple attributes of parcel service is calculated as about 2,349.6 KRW for the safety attribute, about 829.3 KRW for the reliability attribute, about 588.5 KRW for the quickness attribute, and about 358.8 KRW for the kindness and customer service attribute, according to the estimation model without covariates. The overall results indicate that the safety attribute ranks highest among parcel service attributes, followed by the reliability attribute, quickness attribute, and kindness and customer service attribute. These results can be useful in the decision-making process for establishing desirable pricing policies for parcel service.

Economic theory tell us, consumers always make a choice to maximize their utility. In the market system, consumers' choices are revealed and policy maker taking into account the aggregated consumers choice such as price, supply and demand. However, water resources as a public goods, therefore typically there is no market and does no aggregated information for residential water use. This study explore the consumers' willingness to pay for higher quality for residential water. Over 1,000 households responded for this survey and willingness to pay has been estimated. Furthermore, consumers' behaviors of residential water are examined. Consumers are willing to reduce the amount of water use with more than 50% of increasing water price, but stay almost constant with less than 25% of increasing which mean that current price level is not high enough to derive water saving. If consumers can have better quality of water, they willing to pay additional 16%, $153\;won/m^3/month$, more than their current price. Based on the derived information, we suggested policy direction for residential water policy.

The purpose of this study is to examine the effects of digital cultural contents characteristics, perceived values and perceived risks on customer satisfaction and purchase intentions for Chinese consumers, and contribute to the development of digital cultural contents. In addition, a total of 328 valid samples were obtained through an online survey and empirical analysis was conducted. The analysis results of the study are as follows. First, except for creativity, which are characteristics of digital cultural contexts, entertainment and interactivity also have a significantly positive effect on both customer satisfaction and purchase intention. Second, perceived value has a significant positive effect on customer satisfaction and purchase intention, whereas perceived risk does not have this significant effect. Third, customer satisfaction has a partial mediating effect between the three factors(entertainment, interactivity, perceived value) and purchase intention. Therefore, to promote the development of digital cultural contents, we could promote consumers' purchase behavior by improving satisfaction through content entertainment, communication between content producers and service providers, and unity and value that customers actually feel during the consumption process.

블록체인 기술은 '새로운 산업을 만드는 구조'는 아니다. 오히려 과거 인터넷이 도입되면서 사회, 경제 모델 전반이 바뀐 것에 비하면 작은 변화에 가깝다고 할 수 있다. 하지만 블록체인은 높은 보안성과 투명성을 기반으로 기존 산업의 기대 효용을 높여 주고, 다양한 시도를 가능하게 만들어 줄 것이라는 점에서 매우 기대되는 분야이기도 하다. 블록체인은 인터넷 이후의 다른 기술과는 확연히 다르다는 주장을 유심히 살펴볼 필요가 있다. 왜냐하면 블록체인이 인터넷과 우리 사회구조를 어떻게 혁신 시킬 수 있는지, 인터넷 이후의 마케팅 세계가 어떻게 변해왔는지, 소비자는 또 어떻게 변해 왔는지 우리는 쉽게 알 수 있기 때문이다. 이처럼 현재 우리 사회는 "새로운 것을 만들기보다는 효율성과 사회의 신뢰성, 콘텐츠 가치의 투명성을 높여 주는 것이 블록체인의 기술이다"라고 정의할 수 있다. 그렇다면 블록체인 기술의 혁신이 미디어 산업 분야에도 접목되어 새로운 동력으로 작용 할 수 있을 것인가? 이같은 질문과 함께 본 고에서는 블록체인과 콘텐츠 산업, 블록체인과 미디어 서비스 구조, 새로운 서비스 사례 및 기존 스트리밍 서비스, 콘텐츠 제작 및 유통 분야 변화, 그리고 유료 콘텐츠 거래, 디지털 콘텐츠의 효율적인 저작권 관리 분야에서 그 역할과 비중이 어떻게 적용되어 효과가 나타나게 될 것인지에 대해 방송 현업 종사자의 시각에서 살펴보았다. 결국 이러한 신기술을 적극 활용하기 위해서는 블록체인 기술이 갖는 신뢰와 가치라는 근본적인 사항과 미디어업계 종사자들의 긍정적인 인식 변화와 함께 블록체인 미디어 비즈니스 생태계 조성을 위한 연구와 파일럿 적용 등 실험적 여정들이 뒤따라야 할 것이다.

This study testified the influence factors like quantities of advertising, number of hardware and software that are converged, effect on feature fatigue of convergence product. When consumers perceive higher numbers of hardwares in a smart phone, they feel its higher usefulness and complexity. This means that numbers of hardwares is the major factor that enhances consumer's usefulness but, at the same time, it cause perceived leads to higher usefulness in using smart phone, it didn't effect on complexities. It is also important strategy for smart phone companies to provide a lot of useful softwares(applications) to satisfy consumers. Finally, complexity was important factor that lead to higher feature fatigue of consumers. This indicates that smart phone companies have to find adequate numbers of convergence for their new smart phone.

The internet has the capabilities of supporting and facilitating several forms of consumer interaction including one-to-one, one to many, or many-to-many interactions. Especially, previous studies revealed that the Online Word-of-Mouth communication is widely used as a source of customer's information seeking and purchase decision making. Even with this importance of the Online Word-of-Mouth communication on internet, few research has systematically addressed the issue. This study investigates the effect of interpersonal communication on consumers' information search activities and develops a model that depicts the key antecedents and mediating variables of interpersonal communication in internet shopping environment. The results are as follows: First, choice uncertainty, perceived risk, and knowledge uncertainty play an important role for perceived usefulness. Second, perceived usefulness has directly affected interactive communication of consumers' communication style. Thus, it is essential for internet companies to find ways to encourage their customers to engage in word-of-mouth communication.

Contingent Valuation Method (CVM), as non-market valuation approach, has been criticized on that respondents may not realistically reflect their budget constraints in answering willingness to pay (WTP) for hypothetical CV questions. This paper empirically estimates the income calibration factor associated with CV responses through combining travel cost method and contingent valuation method in a utility-theoretic framework. The joint model of recreation demand function and contingent WTP function was applied to an important case study on the Man Kyoung River system, whose water quality is at issue because of the Sae Alan Kum reclamation project. Relevant economic variables such as price, income and water quality had significant influence as anticipated by the economic theory. Equally important, the income calibration factor was not significantly different from one, suggesting that the systematic discrepancies of CV responses relative to the actual behavior was not detected at least in terms of budget exaggeration. Overall, this study supports the notion that carefully designed CVM studies can provide informative data on individuals' willingness to pay for environmental quality changes.
