The proliferation of online customer reviews has completely changed how consumers purchase. Consumers now heavily depend on authentic experiences shared by previous customers. However, deceptive reviews that aim to manipulate customer decision-making to promote or defame a product or service pose a risk to businesses and buyers. The studies investigating consumer perception of deceptive reviews found that one of the important cues is based on review content. This study aims to investigate the impact of the information amount of review on the review truthfulness. This study adopted the Information Manipulation Theory (IMT) as an overarching theory, which asserts that the violations of one or more of the Gricean maxim are deceptive behaviors. It is regarded as a quantity violation if the required information amount is not delivered or more information is delivered; that is an attempt at deception. A topic modeling algorithm is implemented to reveal the distribution of each topic embedded in a text. This study measures information amount as topic diversity based on the results of topic modeling, and topic diversity shows how heterogeneous a text review is. Two datasets of restaurant reviews on Yelp.com, which have Filtered (deceptive) and Unfiltered (genuine) reviews, were used to test the hypotheses. Reviews that contain more diverse topics tend to be truthful. However, excessive topic diversity produces an inverted U-shaped relationship with truthfulness. Moreover, we find an interaction effect between topic diversity and reviews' ratings. This result suggests that the impact of topic diversity is strengthened when deceptive reviews have lower ratings. This study contributes to the existing literature on IMT by building the connection between topic diversity in a review and its truthfulness. In addition, the empirical results show that topic diversity is a reliable measure for gauging information amount of reviews.

This paper investigates the existence of a long-run relationship between world oil price and consumer price index for Korea during 1983~1999. The cointegration and error correction modelling approaches have been applied. Empirical results suggest that there exists a long-run relationship among world oil prices. consumer prices, M2 and a production gap variable. The dynamic behavior of the relationship has been investigated by estimating a error correction model, in which the error correction term have been found significant. The error correction model has also been found to be robust as it satisfy almost all relevant diagnostic tests.

지금까지 많은 리뷰 연구가 이루어져 왔음에도 불구하고 소비자들이 남긴 리뷰들 중 대표적인 리뷰의 위치나 크기를 소비자들이 인식할 수준만큼 강조하는 리뷰, 이른바 강조된 리뷰에 대한 연구는 부족한 실정이다. 본 연구는 강조된 리뷰의 노출 방식에 따른 소비자들의 인식 차이를 확인하는 것이 주된 목표이다. 이를 위해 가상의 온라인 리뷰 페이지를 제작하여 최종적으로 강조된 리뷰가 없는 이미지를 보여주는 집단 23명, 긍정적으로 강조된 리뷰만 노출하여 보여주는 집단 61명, 그리고 긍정적으로 강조된 리뷰와 부정적으로 강조된 리뷰를 모두 노출하여 보여주는 집단 87명을 대상으로 분석하였다. 분석 결과, 강조된 리뷰의 노출 방식에 따른 차이는 리뷰의 유용성 측면에서는 유의한 수준으로 유용성에 양의 상관관계가 나타났으나, 회의감에는 유의한 영향을 주지 않았다. 또한 리뷰의 유용성과 플랫폼 신뢰도와는 유의한 양의 상관관계, 리뷰의 회의감과 플랫폼 신뢰도와는 유의한 음의 상관관계가 나타났으며, 최종적으로 플랫폼 신뢰도와 사용 의도와의 관계는 유의한 수준으로 긍정적인 영향을 미쳤다. 모든 분석 결과에서 상품군에 따른 차이는 거의 없었다. 이를 통해, 온라인 쇼핑몰의 리뷰를 설계할 때 잠재적인 소비자들의 사용 의도 및 신뢰도를 높이기 위해서 긍정적으로 강조된 리뷰와 부정적으로 강조된 리뷰를 모두 보여주는 것이 중요하다는 점을 시사할 수 있다.

Smartphone use is rapidly spreading due to the advantage of being able to connect to the Internet anytime, anywhere--and mobile app development is developing accordingly. The characteristic of the mobile app market is the ability to launch one's app into foreign markets with ease as long as the platform is the same. However, a large amount of prior research asserts that consumers behave differently depending on their culture and, from this perspective, various studies comparing the differences between consumer behaviors in different countries exist. Accordingly, this research, which uses online product reviews (OPRs) in order to analyze the cultural differences in consumer behavior comparatively by nationality, proposes to compare the U.S. and South Korea by selecting ten apps which were released in both countries in order to perform a sentimental analysis on the basis of star ratings and, based on those ratings, to interpret the sentiments in reviews. This research was carried out to determine whether, on the basis of ratings analysis, analysis of review contents for sentiment differences, analysis of LDA topic modeling, and co-occurrence analysis, actual differences in online reviews in South Korea and the U.S. exist due to cultural differences. The results confirm that the sentiments of reviews for both countries appear to be more negative than those of star ratings. Furthermore, while no great differences in high-raking review topics between the U.S. and South Korea were revealed through topic modeling and co-occurrence analyses, numerous differences in sentiment appeared-confirming that Koreans evaluated the mobile apps' specialized functions, while Americans evaluated the mobile apps in their entirety. This research reveals that differences in sentiments regarding mobile app reviews due to cultural differences between Koreans and Americans can be seen through sentiment analysis and topic modeling, and, through co-occurrence analysis, that they were able to examine trends in review-writing for each country.

The online shopping environment has radically changed consumer shopping behavior. Without the actual physical shopping experience in a brick-and-mortar store, consumers make purchasing decisions over the Internet. They make an effort to obtain product information not only from online merchants, but also from previous purchasers in order to make an informed decision. Accordingly, customer comments are expected to have a significant impact on decisions to purchase goods and services online. This paper focuses on one type of electronic word-of-mouth, the online consumer review. It derives several motivations why customers post product reviews on shopping mall sites. Customer motives were identified through an in depth one-on-one interview with twenty female respondents conducted twice from June $17^{th}$ to September $11^{th}$, 2009. The interviews lasted between 40 and 60 minutes. The results showed that consumers write product reviews based on six motivations: to receive a reward or remuneration for writing a product review, to share information with other customers, to improve the quality of goods and services, to reduce customer dissatisfaction, to recommend products and services, and to derive pleasure.

This study intends to recognize the old as an independent consumer, and to examine the behavioral characteristics of the old through literature review. This study also tries to suggest the direction of study on the elderly consumers' behavior. It has been generally accepted that the elderly consumers are highly constricted in purchase behavior or in information process capacity by the decline of biological competence. But according to the literature review, this general viewpoint does not reflect the reality. The literatures say that the old consumers do not so much differ from the non-old consumers in behavioral characteristics. They rather seem to be more active consumers. Nevertheless, what they claim could be a fallacy due to the overspecialization of sample. And another direction of future research is to change the age boundary of the old. The existing studies were largely based on the distinction between the old and the non-old by the age of 60 or 65. It is possible that behavioral difference is diffused by the common purchasing patterns of cohort around the age of 60 or 65. Accordingly it would be a good attempt to widen the range of age group more than 10 years.

FTA 체결국 제품의 관세인하로 수입증가 효과가 발생하며, 또한 관세가 인하됨으로써 국내소비자 가격이 하락함으로써 소비자의 후생이 증대하고 있다. 그러나 소비자에게 관세인하분 만큼의 후생이 소비자에게 전환되어야 함에도 불구하고 가격변동이 없으며, 오리려 가격이 상승하고 있는 현상이 발생하고 있다. 본 연구는 인구통계학적 툭성인 성별, 연령별, 직업별로 FTA 체결 국가의 제품구매와 FTA 체결국 제품의 구매이유를 분석한 후, 이들 항목을 중심으로 소비자후생을 분석하여 통상정책적 측면에서 시사점을 제공하고자 한다. 연구에서 나타난 바와 같이 FTA 체결국가에 제품의 후생수준을 분석한 결과 대체적으로 보통이다는 결론을 많이 나타났으며, 성별, 연령별, 직업별로 분석한 결과 약간의 차이는 있지만 전반적으로 동일한 후생수준을 나타나고 있다는 것을 알 수 있다.

This research analyzes the influence of mobile commerce characteristics on consumer's purchase intention using a theoretical Technology Acceptance Model (TAM) constructed on previous studies and a review of the literature to explain the effect of mobile fashion shopping characteristics on consumer's purchase intention. In constructing structural equation model, Mobile commerce characteristics variables such as 'security', 'enjoyment', and 'personalization' were selected as external variables affecting TAM. A questionnaire was distributed to consumers in their 20's-30's who had purchased fashion products using a mobile shopping channel. Statistical methods of confirmatory factor analysis, correlation, and covariance structural analysis using Amos 19.0 package were employed for the analysis of 453 effective data responses. The results were as follows. First, extended TAM was shown be the appropriate model to explain the influence of mobile commerce characteristics on consumer's purchase intention in mobile fashion shopping. Second, 'security' had a significant positive influence on perceived usefulness (PU), however it affected perceived ease of use (PEOU) negatively. Third, 'enjoyment' had a significant influence only on PEOU, while 'personalization' was found to affect both PEOU and PU significantly. Fourth, PEOU affected PU significantly. Finally, both PEOU and PU had a significant influence on consumer's purchase intention.
