Efficiency comparison of the Wilcoxon tests in paired and independent survey samples

The efficiency concepts of Bahadur and Pitman are used to compare the Wilcoxon tests in paired and independent survey samples. A comparison through the length of corresponding confidence intervals is also done. Simple conditions characterizing the dominance of a procedure are derived. Statistical tests for checking these conditions are suggested and discussed.     

It’s not how old you are but how you are old: A review on aging and consumer behavior

The paper presents a review of 128 studies on the behavior of older consumers published in the last 35 years (from 1980 to 2014) in 35 peer-reviewed journals. The purpose of the procedure is twofold: First, we aim to summarize results on age-related changes in consumer research. Second, by doing so, we evaluate the relative importance of age-related factors (chronological, biological, psychological, and social age as wells as life events and life circumstances) in research on older consumers. Results of the review show that research on older consumers is still dominated by investigations using chronological age. Influences of other aspects of the aging process, although recommended by previous research reviews and providing valuable insights, are still playing a minor role in the investigation of consumer behavior. Research with alternative age measures is still in an early, exploratory stage and future studies should include specific aspects as well as multitheoretical models of aging.     

Consumer adoption of Internet banking in Jordan: Examining the role of hedonic motivation,habit, self-efficacy and trust

Despite the rapid growth of Internet banking (IB), customers in developing countries still hesitate to adopt this technology and its use in the Middle East remains low. This study aims to identify and examine the factors that predict behavioural intention and adoption of IB in Jordan. Four factors – hedonic motivation, habit, self-efficacy and trust – are proposed in a conceptual model. Data was collected by means of a survey with bank customers in Jordan. Structural equation modelling (SEM) was used to analyse the data. The results strongly supported the conceptual model. Further, hedonic motivation, habit, self-efficacy and trust were all confirmed to have a significant influence on behavioural intention. Trust was found to be strongly predicted by both hedonic motivation and self-efficacy. This study provides both academics and practitioners with an insight into the factors that can be used to encourage customer adoption of IB specifically in a Middle East context.
