This study focus on the effect of switching barrier on negative performance. To suggest the negative effect of switching barrier, we reviewed the researches on service-failure and attribution theory. The model which we present in the research study includes the antecedents and consequences of negative emotions(regret, resentment) that caused by switching barriers. The former factors consist of internal attribution and external attribution. The latter factors consist of acceptance, complain, negative word-of-mouth. Survey research is employed to test these hypotheses. Previous researches, such as service marketing, psychology, have been referenced to measure constructs. We collected data involving various service area, and used 189 respondents to analyze these data with LISREL structural modeling. The hypothesized relationships were statistically significant. Internal attribution had positive effect on regret and external attribution had positive effects on resentment. And then regret had significant effects on acceptance and complain behaviour. Also resentment strongly effects on complain behaviour and negative word-of-mouth. We concluded with managerial implications, including the potential to deeper understanding switching barrier.

The arrival and expansion of the Internet has extended consumers' options and has provided consumers' opportunities to offer their own consumption. Through a laboratory experiment, we investigated questions: 1) do consumers trust the accuracy of reviews posted by anonymous reviewers or experts and 2) do readers trust negative and positive reviews equally? The messages were created as a form of 4 scenarios for this study. The statistical analysis was conducted using SPSS Win(v.16.0) for descriptive analysis, and t-test. Our results from a 2(positive reviews vs. negative reviews)*2(consumer vs. expert) experiment design showed that there was a significant difference between consumers' review and experts' one in restaurant visit intention(p<.001) and information credibility(p<.001). Also, between positive review and negative one, significant difference was found in restaurant visit intention(p<.001) and information credibility(p<.01). Other results, limitations and future research directions were also discussed.

In the generalization of mobile content use, feedback is a kind of alert that affects content immersion. An alert leads to separation from the content currently being used to transfer to content that raises the alert. Immersive interference can be recognized as a problem in mobile contents use. In this paper, we propose a serious game for overcomes immersion. interference from feedback and the foundation for interrelation research between feedback and immersion. The proposed serious game has been designed to present three kinds of feedback, specifically positive, negative, and hybrid feedback, through social information about the user. We also conducted an experiment to examine the correlation between three kinds of feedback and immersion while consuming digital content. The result of the experiment showed that negative feedback leads to higher immersion than positive feedback.

This research investigates how a service provider's response(s) to negative customer reviews influences the success of accommodation services in the context of online accommodation reservation platforms. Specifically, we attempt to comprehend the important role of attentive and instant responses to users' negative review comments in fostering future success by analyzing panel data on 856 motels registered in the largest accommodation reservation platform in Korea. The results present that response volume (Attentiveness) and faster responses (Timeliness) are positively associated with success. We further find that the two review-response strategies have a positive interaction effect on success. Moreover, we show that the effect of review responses is strengthened when the reputation of motels drops. The key findings of this research offer a set of practical guidelines for accommodation owners to achieve business success by effectively managing customer reviews and claims

This paper investigates the asymmetric effect of social sentimental on an individual stock price return. For this purpose, four companies such as POSCO, Korean Electricity, AMORE PACIFIC, KIA Motors are chosen from KOSPI listed companies in terms of dataperspective. The main estimation results are as follows: the positive opinions affect only the stock prices return of three companies while the negative opinions affect all of the companies. It shows that positive or negative texts give asymmetric effect on stock price return and the effect of negative opinions is bigger than that of positive opinions. The results imply that investors are more sensitive to the negatives since they have the tendency of loss aversion. Also, it indicates that subjective opinion on SNS can be used as the proxy for the investment sentiment.

The information recommendation system offers selected documents according to information needs of dynamic users. User's needs are expressed as profiles consisting of one or more words and may be changed into some specifics through relevance feedback made by users during the recommendation process. In previous research, users have entered relevance information by taking part in explicit relevance feedbacks and learned user profiles using the positive relevance feedbacks. In this paper, we learn user profiles using not only positive relevance feedback but negative relevance feedback and reinforcement learning. To compare the proposed with previous method, we performed experiments to evaluate recommendation performance of the same topic. As a result, the former shows the improved performance than the latter does.

The current study examined the moderating effect of visual cues in eWOM on the relationship between perceived risk and purchase intention. Specifically, the study tested the different directions of the moderating effect in positive and negative eWOM. Two studies from a 2 (perceived risk: high vs. low) by 2 (visual cue: presence vs. absence) experimental design were used with online subjects. Findings from study 1 (n=123) supported that visual cues in positive eWOM help to reduce the negative effect of perceived risk on purchase intention. However, study 2 (n=122) showed that visual cues in negative eWOM intensify the negative effect of perceived risk on purchase intention. The findings demonstrated that visual cues in eWOM influence consumers' decision under high risk conditions. We discussed findings of this study how visual cues in positive and negative eWOM can be strategically managed for new online sellers.
