The traditional three-step procedure for correcting for heteroskedasticity uses a consistent but biased estimator for the variances 2 t in enacting the second step. An estimator is developed here that is unbiased in the presence of heteroskedasticity. Its behavior is examined along with the traditional estimator and another known to be unbiased in the absence of heteroskedasticity. The behavior...

The article investigates the finite sample properties of estimators for spatial autoregressive models where the disturbance terms may follow a spatial autoregressive process. In particular we investigate the finite sample behavior of the feasible generalized spatial two-stage least squares (FGS2SLS) estimator introduced by Kelejian and Prucha (1998), the maximum likelihood (ML) estimator, as we...

While most of the computational trust models devote to truthfully detecting trustworthy individuals, much less attention is paid to how these models are perceived by users, who are the core of the trust machinery. Understanding the relation between trust models and users‟ perception of those models may contribute for reducing their complexity, while improving the user-experience and the system ...

Previous research has primarily examined consumers’ perceived usefulness of web sites and trust in the web retailer as two major predictors of web site use and e-commerce adoption. While the consumers’ repeated behavior in the past (i.e., habit) may contribute to continuance behavior, it has not been investigated. This article includes habit as a primary construct along with perceived usefulnes...

While an increasing number of trust studies examine technological artifacts as trust recipients, we still lack a basic understanding of how technology trust “fits” into the broader nomological net espoused by trust theories. This paper adopts a measure of technology trust comprised of IT-specific dimensions. We then articulate a research model that separates technology trust from interpersonal ...

Electronic commerce researchers have retention of Consumers post-adoption continuance behavior attendees induce deep trust and service quality of online shopping behavior, thereby contributing to higher revenue and marketing strategy based on social exchange theory. This study provides additional information about the path from the service quality and trust to continuous usage. Also, this study...

In this issue of Neuron, a study by Baumgartner et al. investigates the influence of oxytocin on trust behavior and its neural mechanisms. The authors report that, following breaches of trust, oxytocin facilitates prosocial behavior while modulating neural signals in the amygdala and caudate nucleus. The findings have implications for an array of mental disorders where social behavior is compro...

A key challenge in emerging service-oriented computing is the need to establish trust-based loosely coupled partnerships between previously unknown services. A dependable trust framework is essential to capture and maintain realistic trust information based on different requirements of participating services. Most existing trust management frameworks assume that the participating services perfo...

This article reports the findings of a longitudinal study of temporary virtual teams and explores the role of behavior control on trust decline. We conducted an experiment involving 51 temporary virtual teams. Half of the teams were required to comply with behavior control mechanisms traditionally used in colocated teams. Their counterparts were allowed to self-direct. Cynthia Beath was the acc...

Trust in networks is the essential foundation for follow-on security mechanisms, such as key management and secure transmission. In this paper, we concentrate on trust establishment in self-organized, distributed and resourceconstraint networks. Such networks pose formidable challenges on trust establishment due to lack of infrastructure and centralized servers. We model our trust establishment...
