Online trust is one of the main determinants of the success of e-retailers and much research has dealt with website features triggering consumer trust to them. Another stream of research focuses on the psychological antecedents to online trust; i.e., what ''happens'' in the consumer's mind before or while a person decides to trust an e-retailer? So far, each effort has focused on only a few selected aspects of this trust formation process. No study has attempted to identify major psychological antecedents of trust. Our work identified the relative importance of the antecedents of institution-based trust in e-retailing; i.e., trust people have in it in general. A review of the literature reveals a large number of potential psychological antecedents. These can be categorized into five group of factors: personality-based, perception-based, attitude-based, experience-based, and knowledge-based. The five categories are hypothesized to influence institution-based consumer trust in e-retailing. According to our results, perception based factors are the main determinants of consumer trust in e-retailing. Consumers do behave, after all, rationally. # 2004 Published by Elsevier B.V.

The study of the relationships between information technology (IT), environmental organizational issues and firm performance is a cutting-edge research topic for the information systems (IS) community. However, at present we know very little about these relationships. Drawing on the perspective of ITenabled organizational capabilities and the literature on organizations and the natural environment, our study introduces conceptually the construct organizational capability of proactive corporate environmental strategy to the IS field. We propose that IT capability may enable the implementation of a proactive environmental strategy and that this strategy could play a significant role in determining the business value of IT. Using structural equations modeling with data collected from 63 firms, we find that IT capability is an enabler of proactive environmental strategy and that this strategy plays a significant role in mediating the effects of IT on firm performance. Our study provides initial evidence on the role of IT in the implementation of proactive environmental practices. Our results suggest to IT executives that their decisions matter in shaping environmental sustainability, which in turn will generate business value from IT.
