TL;DR: A longitudinal study with online consumers supports the proposed e-commerce adoption model, validating the predictive power of TPB and the proposed conceptualization of PBC as a higher-order factor formed by self-efficacy and controllability.

TL;DR: This study draws upon and extends the principal-agent perspective to identify and propose a set of four antecedents of perceived uncertainty in online buyer seller relationship superceived information asymmetry, fears of seller opportunism, information privacy concerns, and information security concerns which facilitate online exchange relationships by overcoming the agency problems of adverse selection and moral hazard.

TL;DR: In this article, specific risk facets were operationalized, integrated, and empirically tested within the Technology Acceptance Model resulting in a proposed e-services adoption model, which indicated that adoption is adversely affected primarily by performance-based risk perceptions, and perceived ease of use of the e-service reduced these risk concerns.

TL;DR: In this article, the authors integrate sociological and economic theories about institution-based trust to propose that the perceived effectiveness of three IT-enabled institutional mechanisms-specifically feedback mechanisms, third-party escrow services, and credit card guarantees-engender buyer trust in the community of online auction sellers.
