We explore additive models that combine both parametric and nonparamet-ric terms and propose a p n-consistent backktting estimator for the parametric component of the model. The theoretical properties of the estimator are developed for the case with a single nonparametric term and extended to an arbitrary number of nonparametric additive terms. An estimator for the optimal band-width making min...

Most of the peers accessing the services are under the assumption that the service accessed in a P2P network is utmost secured. By means of prevailing hard security mechanisms, security goals like authentication, authorization, privacy, non repudiation of services and other hard security issues are resolved. But these mechanisms fail to provide soft security. An exhaustive survey of existing tr...

We analyze the determinants of trust and trustworthiness in a matching equilibrium when agents have heterogeneous predispositions towards trusting and trustworthy behavior, there is transmission of information via both individual and collective reputations, and successful matches may persist. In new matches, more social trustworthiness breeds more individual trust. However, whether more social ...

In this paper we present results of a user study that we conducted with 21 subjects to investigate whether initial user trust is accompanied by unconscious bodily responses which enable more objective measurements than user reports. In particular, we recorded the user’s eye gaze and heart rate to evaluate whether users respond differently when interacting with a web page that is supposed to bui...

Incentive Design and Trust: Comparing the Effects of Tournament and Team-Based Incentives on Trust We explore the extent to which the structure of incentives affects trust. We hypothesize that the degree to which different incentive mechanisms emphasize competition (via the perceived intentions of others) and entitlements (via the perceived property rights) will affect individuals’ subsequent b...

When does a person who has been trusted reciprocate that trust? Kiyonari, Yamagishi, Cook, and Cheshire (2006) compared behavior in trust games and faith games and showed that in one-shot games, players who were trusted did not reciprocate that trust. In an experiment using trust games and dictator games, we examined what type of trust would elicit reciprocation of that trust by the trustee. In...

In this paper, we study the asymptotic distributions for least-squares (OLS), fully modi ed (FM), and dynamic OLS (DOLS) estimators in cointegrated regression models in panel data. We show that the OLS, FM, and DOLS estimators are all asymptotically normally distributed. However, the asymptotic distribution of the OLS estimator is shown to have a non-zero mean. Monte Carlo results examine the s...

Although trust is widely acknowledged as critical in virtual settings, little is known regarding the antecedents and consequences of trust in leaders of virtual groups. Adopting a multi-level perspective, we propose the leadership’s communication behavior and the broader cultural context in which the group operates determine trust in leaders of virtual groups, which in turn affects the performa...
