Does Faith Matter in Mutual Funds Investing? Evidence from Saudi Arabia

This article investigates one of the most vital issues in the Islamic mutual fund literature: Are there any costs associated with investing in Islamic mutual funds? We used a unique sample of 143 Saudi mutual funds and grouped them into portfolios based on their geographical focus, Shariah compliance, and the Saudi market trend (overall, bull, bear, and the crisis period). Findings suggest there is a benefit from adhering to Shariah law in locally-focused Saudi mutual funds. However, there is a cost of this adherence in internationally-focused Saudi mutual funds. Finally, in Arab-focused Saudi mutual funds, there is neither a cost nor a benefit.     

The Reluctant Analyst

We estimate the dynamics of recommendations by financial analysts, uncovering the determinants of inertia in their recommendations. We provide overwhelming evidence that analysts revise recommendations reluctantly, introducing frictions to avoid frequent revisions. More generally, we characterize the sources underlying the infrequent revisions that analysts make. Publicly available data matter far less for explaining recommendation dynamics than do the recommendation frictions and the long‐lived information that analysts acquire but the econometrician does not observe. Estimates suggest that analysts structure recommendations strategically to generate a profitable order flow from retail traders. We provide extensive evidence that our model describes how investors believe analysts make recommendations, and that investors value private information revealed by analysts' recommendations.     

Relevant and Preferred Public Service: A study of user experiences and value creation in public transit

The present study shows how public transit organizations’ achievement of twenty-five different service requirements affected their offerings’ relevance and preference among 930 users. This article increases the understanding of how strategic choices and prioritization between various service requirements affect both the effectiveness and efficiency of (public) service offerings.

The Role of Website Quality on PAD,Attitude and Intentions to Visit and Recommend Island Destination

This study investigates the effect of website stimuli on positive attitude and intentions to visit and recommend, through three emotional responses (pleasure, arousal and dominance). The model was tested regarding three island‐related websites. Findings show the role of emotions as mediators between website quality attitude and intentions. Arousal and dominance are revealed to be more important in the formation of a positive attitude than pleasure. Visual appeal and ease of use, followed by information, seem to be the most important components in forming a perception of the islands' website quality.

Celebrity endorsement: How celebrity–brand–user personality congruence affects brand attitude and purchase intention

The present study provides and tests a conceptual framework aimed at comparing the relative effectiveness of celebrity–user, brand–celebrity, and user–brand personality congruence on brand attitude and brand purchase intention (BPI) thereafter. The data collection was done via an online survey of a representative group of consumers (n = 431) located across India. Hypotheses were tested using regression analysis with mediation approach. The results indicate that while user–brand and brand–celebrity personality congruence have a significant impact on brand attitude and purchase intention, celebrity–user congruence does not. Further, brand attitude is found to be a partial mediator on the relationship between the pair-wise personality congruence on BPI. The findings have major implications for marketers in understanding the significance of personality congruence among celebrity–brand–user in the formation of brand attitude and purchase intention that can be used in positioning and in increasing the advertising effectiveness of brands using celebrity endorsement. The present study is a pioneer in contributing to the celebrity endorsement literature by investigating the relative impact of three pairs of personality congruence: celebrity–brand, brand–user, and celebrity–user, on brand attitude and BPI, thereby supporting the applicability of McCracken's Meaning Transfer Model [McCracken (1989), The Journal of Consumer Research, 16 (3) 310–321) and the Hierarchy-of-effects model (Lavidge and Steiner (1961), Journal of Marketing, 25 (6) 59–62].
