Facebook commerce has become increasingly popular, especially for consumer-to-consumer (C2C) transactions. This trading channel is highly utilized for local transactions and for connecting people with similar interests, thus making it an especially useful channel for buying and selling pre-owned luxury products. This study aims at examining the determinants of customers' social image satisfaction with the purchase of pre-owned luxury brand watches via the Facebook-commerce channel. Data were collected from two hundred Thai consumers who are the members of the pre-owned luxury brand watch Facebook group. The results revealed factors which significantly influence customers' social image satisfaction toward a pre-owned luxury brand watch. The findings also showed that the perceived symbolic value plays an important mediating role in the relationship between perceived experiential value and social image satisfaction.

Previous studies on the intention to use mobile payment were mainly conducted using traditional technology acceptance models, which focus on positive factors and ignore negative factors influencing the intention to use mobile payment in both developed and developing countries. This study is conducted in a newly emerging country, Vietnam – a trusted destination for multinational companies to do business and reposition their global supply chains. With the integration of positive and negative factors into an extended research model to examine their influence on the intention to use mobile payment, the results show that perceived privacy and perceived security contribute to overall perceived risk. Moreover, perceived risk and perceived compatibility are two determinants of intention to use mobile payment. Theoretical and managerial implications are drawn and directions for future research are outlined.

Online consumer reviews have been shown to play an important role that can influence consumers' attitudes, behaviors, and purchasing decisions. This study seeks to understand factors that affect user intention to use online consumer reviews. To examine this area, this paper theorizes multiple constructs that may influence intention to use. The subjects in this study were 466 online Vietnamese consumers. The data were analyzed using structural equation modeling, and five of the seven hypotheses were found to be significant. This study found several results not found in prior studies. The construct perceived online review importance is found to be important in influencing intention to use online reviews. Both perceived usefulness and perceived credibility influenced consumers' perceptions on the importance of online reviews. The study findings contribute to the research field of online consumer reviews and provide new insights into intention to use online consumer reviews for a developing country, different from prior studies that have focused on developed countries.
