When the nominal interest rate reaches its zero lower bound, credibility is crucial for conducting forward guidance. We determine optimal policy in a New Keynesian model when the central bank has imperfect credibility and cannot set the nominal interest rate below zero. In our model, an announcement of a low interest rate for an extended period does not necessarily reflect high credibility. Eve...

This paper discusses two trends that threaten to undermine the effectiveness of online social marketing interventions: growing mistrust and competition. As a solution, this paper examines the relationships between Web site credibility, target audiences’ active trust and behaviour. Using structural equation modelling to evaluate two credibility models, this study concludes that Web site credibil...

In this article, we focus on the potential influence of a scientist's advocacy position on the public's perceived credibility of scientists as a whole. Further, we examine how the scientist's solution position (information only, non-controversial, and controversial) affects the public's perception of the scientist's motivation for sharing information about specific issues (flu, marijuana, clima...

The credibility of an instructional simulation is the most important issue in distance education, where it may replace hands-on activities. This credibility is based in large part upon verisimilitude, a perception strongly influenced by the simulation’s realism. This paper presents a case study encompassing the design process of a simulation-based virtual laboratory, which was guided by a reali...

Characteristics of persuasive message sources have been extensively studied. However, little attention has been paid to situations when people are motivated to form an evaluation of the communicator rather than the communicated issue. We postulated that these different foci can affect how a source validates message-related cognitions. Participants focused on the source (Studies 1 and 2) or the ...

Established guidelines for causal inference in epidemiological studies may be inappropriate for genetic associations. A consensus process was used to develop guidance criteria for assessing cumulative epidemiologic evidence in genetic associations. A proposed semi-quantitative index assigns three levels for the amount of evidence, extent of replication, and protection from bias, and also genera...

Recent Home Office research indicates that complainants in sexual offence cases still struggle to gain credibility in the eyes of police, prosecutors and jurors. This article examines some of the credibility barriers confronting victims of sexual offences within the criminal process. In the USA, prosecutors have utilised expert witness testimony in an effort to educate jurors and restore credib...

abstract geopedology is a systematic approach of geomorphic analysis for soil mapping which focuses the field operation mainly on sample area. the purpose of this study is to determine the credibility of generalization of the results of geopedological approach for similar landforms in the borujen region, using diversity and similarity indices in a soil taxonomic hierarchical structure. after a ...

This paper presents a theory of the real effects of disinflation. As in New Kcyncsian models, price adjustment is staggered across firms. As in New Classical models. credihiltty is imperfect: the monetary authorrty may not complete a promised disinflation. The cwnbination of imperfect credibility and staggering yields more plausible results than 4ther of these assumptions alone. In particular. ...

We introduce a class of Bayesian infinite mixture models first introduced by Lo (1984) to determine the credibility premium for a non-homogeneous insurance portfolio. The Bayesian infinite mixture models provide us with much flexibility in the specification of the claim distribution. We employ the sampling scheme based on a weighted Chinese restaurant process introduced in Lo et al. (1996) to e...
