Gefen, David and Straub, Detmar W. (2004): Consumer trust in B2C e-Commerce and the importance of social presence: experiments in e-Products and e-Services. In OMEGA, 32 (6) pp. 407-424.

Reducing social uncertaintyunderstanding, predicting, and controlling the behavior of other peopleis a central motivating force of human behavior. When rules and customs are not sufficient, people rely on trust and familiarity as primary mechanisms to reduce social uncertainty. The relative paucity of regulations and customs on the Internet makes consumer familiarity and trust especially important in the case of e-Commerce. Yet the lack of an interpersonal exchange and the one-time nature of the typical business transaction on the Internet make this kind of consumer trust unique, because trust relates to other people and is nourished through interactions with them. This study validates a four-dimensional scale of trust in the context of e-Products and revalidates it in the context of e-Services. The study then shows the influence of social presence on these dimensions of this trust, especially benevolence, and its ultimate contribution to online purchase intentions.

Gefen, David and Straub, Detmar W. (2003): Managing User Trust in B2C E-Services. In e-Service Journal, 2 (2) pp. 7-24.

One of the major differences between B2C e-services (Business to Consumer Internet-based services) and the more traditional types of consumer services is that websites of e-services frequently lack the social presence of the physical services. This lack of social presence may impede the growth of B2C by hindering the development of consumer trust in the service provider. Human interaction, or at least the belief that the system has characteristics of social presence, is believed to be critical in the creation of trust. Trust itself is a major issue affecting the phenomenal growth rate of e-commerce, according to industry sources and recent academic studies. This study examines the effect of social presence on consumer trust in e-services and the relative importance of consumer trust in comparison with the widely studied TAM (Technology Acceptance Model) beliefs. In a free simulation experiment, 161 MBA student subjects assessed, a popular online travel agency. Findings show that social presence, indeed, affects consumer trust and that trust subsequently has a stronger effect on purchase intentions than TAM beliefs. Implications for e-services are discussed in terms of whether the benefits from adopting an IT depend more on website characteristics like usefulness and ease of use or on consumer trust in the vendor. Managing e-services calls for managing the trust that is engendered in the customer experience on the website. Firms that excel in instilling high degrees of social presence in their websites may prosper more than those that do not.

Gefen, David, Karahanna, Elena and Straub, Detmar W. (2003): Trust and TAM in Online Shopping: An Integrated Model. In MIS Quarterly, 27 (1) pp. 51-90.

A separate and distinct interaction with both the actual e-vendor and with its IT Web site interface is at the heart of online shopping. Previous research has established, accordingly, that online purchase intentions are the product of both consumer assessments of the IT itself-specifically its perceived usefulness and ease-of-use (TAM)-and trust in the e-vendor. But these perspectives have been examined independently by IS researchers. Integrating these two perspectives and examining the factors that build online trust in an environment that lacks the typical human interaction that often leads to trust in other circumstances advances our understanding of these constructs and their linkages to behavior. Our research on experienced repeat online shoppers shows that consumer trust is as important to online commerce as the widely accepted TAM use-antecedents, perceived usefulness and perceived ease of use. Together these variable sets explain a considerable proportion of variance in intended behavior. The study also provides evidence that online trust is built through (1) a belief that the vendor has nothing to gain by cheating, (2) a belief that there are safety mechanisms built into the Web site, and (3) by having a typical interface, (4) one that is, moreover, easy to use.

Rose, Gregory, Khoo, Huoy and Straub, Detmar W. (1999): Current Technological Impediments to Business-to-Consumer Electronic Commerce. In Communications of the AIS, 1 (5) .

Internet and World Wide Web technologies provide the infrastructure for the Electronic Commerce (e-Commerce) revolution now taking place. As a result of these technologies, even the smallest organization can afford to market its wares to hundreds of millions of potential e-Consumers. However, these technologies also pose threats to the very electronic commerce which they enable. For managers to strategize and implement e-Commerce effectively in their organizations, these impediments need to be recognized and understood. While hundreds of articles identify problems with Internet computing or conducting e-Commerce, no unified framework of technological impediments specific to e-Commerce yet exists. The goal of this paper is to identify the primary technological impediments to e-Commerce. Six categories of technological impediments have been identified. Those which appear to pose the greatest threats to the development of e-Commerce are: (1)download delays, (2) limitations in the interface, (3) search problems, (4) inadequate measurement of Web application success, (5) security (real and perceived) weaknesses, and (6) a lack of Internet standards. Associated costs, threats, and limitations specific to e-Commerce are also identified and implications explored. The paper concludes with an assessment of ways to mitigate these obstacles, including design choices, workarounds, and emerging technological solutions. A bibliography of 296 relevant trade press articles is included in the appendix.

Straub, Detmar W. (1989): Validating Instruments in MIS Research. In MIS Quarterly, 12 (2) pp. 147-170.

Calls for new directions in MIS research bring with them a call for renewed methodological rigor. This article offers an operating paradigm for renewal along dimensions previously unstressed. The basic contention is that confirmatory empirical findings will be strengthened when instrument validation precedes both internal and statistical conclusion validity and that, in many situations, MIS researchers need to validate their research instruments. This contention is supported by a survey of instrumentation as reported in sample IS journals over the last several years. A demonstration exercise of instrument validation follows as an illustration of some of the basic principles of validation. The validated instrument was designed to gather data on the impact of computer security administration on the incidence of computer abuse in the U.S.A.
