Information direction, website reputation and eWOM effect: A moderating role of product type

This article examines how the electronic word of mouth (eWOM) information direction (positive vs. negative) and a website's reputation (established vs. unestablished) contribute to the eWOM effect. The article describes a study focusing on the moderating role of the product type (search vs. experience). The results of the experiment show that the eWOM effect is greater for negative eWOM than for positive eWOM, greater for established websites than for unestablished websites, and greater for experience goods than for search goods. The results support the moderating effects of product type on the eWOM information direction-website reputation-eWOM effect relationship. The impact of negative eWOM on the eWOM effect is greater for experience goods than for search goods. Similarly, the impact of website reputation on the eWOM effect is greater for experience goods than for search goods. The findings provide managerial implications for an Internet marketing strategy.     

A comparison of brand loyalty between on the go and take-home consumption purchases

This paper compares consumer brand purchase loyalty for food products bought either ‘on the go’ (OTG), or for take-home consumption. The study uses two UK consumer packaged goods datasets. The first dataset comprises consumers' purchasing of brands in three product categories: soft drinks, crisps, and savory snacks for on the go consumption. The second contains consumers' purchasing of the same brands for take-home consumption. Analysis uses the polarization index as a behavioral loyalty measure, estimated from the Beta Binomial – Negative Binomial Distribution. This measure controls for the difference in purchase rate and brand market share across on the go and take-home. The study finds that consumer loyalty to brands is markedly higher in purchasing for on the go consumption than for take-home consumption; and that the effect is even stronger for larger brands in on the go.     

Creating the right customer experience online: The influence of culture

The effective role of experiential marketing in the differentiation of brands has been documented in both traditional and online services. The digital context of e-retailing makes it both a suitable platform for experiential consumption and an easily accessible shopping method across cultures. In spite of this, investigation of the impacts of cultural differences on the desire for experiential benefits has been very limited in the e-retailing literature. Using Hofstede's (2001) cultural dimensions, this article studies how two student samples of North American and Chinese customers react differently to the experiential values offered on the websites of e-retailing services. The findings support our hypotheses and suggest that offering experiential values on a company's website is more influential for North American than for Chinese customers. More specifically, the influences of experiential values on site involvement and customers' patronage intentions are stronger for North Americans than for Chinese visitors. On the other hand, the impacts of site involvement on site attitudes and the influence of site attitudes on patronage intentions are stronger for Chinese compared with North American customers.     

Consumer acceptance of irradiated food and information disclosure – A retail imperative

There is substantial contribution in the literature for understanding the complex nature of irradiated foods, the growing importance and the controversial views expended by consumers, yet acceptance of these foods for many have not met with optimal recognition. The study extends the theory of planned behaviour antecedents to analyse independent determinants and the influences of risk and trust. The indirect effects are also examined. The study uses multigroup analyses to identify whether consumer's concerns on information for irradiated foods act as moderators in order to provide a better explanatory power.The data was analysed using Structural Equation Modelling on responses obtained from a sample of 322 consumers. The study found that the theory of planned behaviour antecedents successfully predicted behavioural intention for irradiated foods but with some limitations. The findings also demonstrate additional support to show that the robustness of the TPB framework is effective for irradiated foods and addresses the literature calls on research for more theoretical underpinnings. It further addresses retailer implications, as the ultimate decision falls with retailers who assess whether sales for irradiated foods are acceptable depending on consumer demand.     

Trade in health products and population health: A long-run relation

The effect of trade on different economic outcomes has been extensively studied but the literature on the specific effects of trade on health outcomes has remained relatively scanty. Our paper fills in the gap by examining the long-run association between import expenditures on health products and longevity in a cross-country panel setting of 32 developed and 24 developing countries, covering 1990–2018. It accounts for both time-series properties and cross-country heterogeneity, while remaining robust to omitted variables and endogeneity problems, by applying panel cointegration techniques. The results reveal that per capita medical import expenditure on pharmaceuticals, aggregate medical products and medicines have contributed around 0.34, 0.35 and 0.30 percentage points, respectively to the annual increase in life expectancy for an average country in our sample. The findings suggest that higher per capita import expenditure on health products can increase longevity significantly in the long-run. The results remain robust to cross-sectional dependence, sub-samples of developed and developing countries and alternate measures of health outcomes such as adult mortality rates. These findings set the context for treating health product imports as critical for long-term improvements in population health and outlines the need for greater coordination between health and trade policymakers for improving population health.
