Factors influencing Generation Y consumers’ perceptions of eWOM credibility: a study of the fast-food industry

eWOM communication is certainly one of the most influential drivers of purchase decisions. However, little knowledge is available on the factors that influence the trustworthiness and credibility of eWOM communication. To address this research gap, the study aimed to assess whether the three independent variables (homophily, authority and interestingness) have a significant positive indirect effect on eWOM credibility, as mediated by source trustworthiness. The context of the study was fast-food retailers. A cross-sectional survey was conducted and the target population included all Generation Y consumers that visited the fast-food market leaders in Gauteng province, the economic hub of South Africa. Lisrel version 8.8 was used to analyse the results obtained from a realised sample of 362 respondents and to compile the structural equation model. The findings of the study support the research hypotheses formulated and offer a theoretical contribution by enhancing knowledge of the relationships between the variables investigated as well as the factors that could influence eWOM credibility. The study also has meaning to fast-food retailers, as the model could be applied to formulate appropriate strategies and influence the online conversations and perceptions of consumers.     

A method for evaluating and selecting field experiment locations

When marketing researchers perform field experiments, it is crucial that the experimental location and the control location are comparable. At present, it is difficult to assess the comparability of field locations because there is no way to distinguish differences between locations that are due to random versus systematic factors. To accomplish this, we propose a methodology that enables field researchers to evaluate and select optimal field locations by parsing these random versus systematic effects. To determine the accuracy of our proposed methodology, we performed computer simulations with 10,000 cases per simulation. The simulations demonstrate that accuracy increases as the number of data points increases and as consistency increases.     

Treatment patterns and healthcare costs among newly-diagnosed patients with chronic myeloid leukemia receiving dasatinib or nilotinib as first-line therapy in the United States

Objective: To compare treatment patterns and economic outcomes of dasatinib and nilotinib as 1st-line therapies for chronic myeloid leukemia (CML).

Methods: Adult CML patients initiated on first-line dasatinib or nilotinib in 2010–2014 were identified from two large US administrative claims databases. Treatment patterns, tyrosine kinase inhibitor (TKI) adherence and healthcare resource utilization (HRU) and costs were measured from the 1st-line TKI initiation (index date) to the end of follow-up.

Results: A total of 604 and 418 patients were included in the dasatinib and nilotinib cohorts (mean ages = 50.9 and 52.5 years, 46.4% and 45.7% female), respectively. Among the dasatinib patients, 91% started with 100?mg/day, 3% with <100?mg/day, and 6% with >100?mg/day. Among the nilotinib patients, 76% started with 600?mg/day, 16% with >600?mg/day, and 8% <600?mg/day. The dasatinib cohort had a higher hazard of dose decrease (hazard ratio [HR]?=?1.66; p?=?.002) and of switching to another TKI (HR =1.62; p?=?.019) compared to the nilotinib cohort. The hazard of dose increase (HR =0.76; p?=?.423) and treatment discontinuation (HR =1.10; p?=?.372) were not significantly different between cohorts. There was also no significant difference in TKI adherence levels (mean proportion of days covered [PDC] difference over first 6 months = ?0.0003, p?=?.981; mean PDC difference over first 12 months = ?0.0022, p?=?.880) and HRU (inpatient day incidence rate ratio [IRR]?=?1.03, p?=?.930; emergency room IRR =1.26, p?=?.197; and days with outpatient services IRR = 1.01, p?=?.842). The dasatinib cohort incurred higher healthcare costs by $749 per patient per month (p?=?.044) compared to the nilotinib cohort.

Limitation: Information on CML phase and Sokal score was not available.

Conclusions: Dasatinib was associated with an increased hazard of dose decrease and switching to another TKI and higher healthcare costs, vs nilotinib.     

Food and beverage television advertising exposure and youth consumption,body mass index and adiposity outcomes

This study examines the relationships between exposure to food and beverage product television advertisements and consumption and obesity outcomes among youth. Individual‐level data on fast food and soft drink consumption and body mass index (BMI) for young adolescents from the Early Childhood Longitudinal Study, kindergarten cohort, (1998–1999) and adiposity measures for children from the US National Health and Nutrition Examination Survey (2003–2004) were combined with designated market area (DMA) Nielsen media advertising ratings data. To account for unobserved individual‐level and DMA‐level heterogeneity, various fixed‐ and random‐effects models were estimated. The results showed that exposure to soft drink and sugar‐sweetened beverage (SSB) advertisements is economically and statistically significantly associated with higher frequency of soft drink consumption among youth even after controlling for unobserved heterogeneity, with elasticity estimates ranging from 0.4 to 0.5. The association between fast food advertising exposure and fast food consumption disappeared once we controlled for unobservables. Exposure to cereal advertising was significantly associated with young adolescents' BMI percentile ranking, but exposures to fast food and soft drink advertisements were not. The results on adiposity outcomes revealed that children's exposure to cereal advertising was associated with both percent body fatness and percent trunk fatness; fast food advertising was significantly associated with percent trunk fatness and marginally significantly associated with percent body fatness; and exposure to SSB advertising was marginally significantly associated with percent body and trunk fatness. The study results suggest that continued monitoring of advertising is important and policy debates regarding the regulation of youth‐directed marketing are warranted.     

DID TIME INCONSISTENCY CONTRIBUTE TO THE GREAT INFLATION? EVIDENCE FROM THE FOMC TRANSCRIPTS

We use evidence from detailed records of FOMC deliberations to argue that time inconsistency theory can help explain the excessive monetary expansion that characterized Arthur Burns's tenure as Federal Reserve Chairman (1970–1978). The records suggest that the Fed perceived a Phillips curve tradeoff and political pressures that made it difficult to adopt disinflationary policies; the tendency toward excessively expansionary policy was exacerbated by the short-run planning horizon the Committee faced in each of its meetings. We argue that comparative static predictions of the time inconsistency model are consistent with the rise of inflation during the Burns years and its subsequent fall.     

Endorsement of managers following accusations of breaches in confidentiality

Two related studies focused on the effects that a questionable supervisory conduct has on the endorsement and vulnerability of the supervisor, as well as on judgments of supervisory morality. Male and female undergraduate and graduate business students were asked to read the account of a personnel manager who violates employee confidentiality concerning certain personality test results, but who has had a previous record of increasing or decreasing productivity. The studies revealed varying patterns of leadership endorsement, vulnerability, and judgments of morality following this questionable or unethical conduct as a result of the personnel's manager's record and the subjects' sex.

Anticipatory consumer socialization

While most consumer socialization research has focused upon the development of consumer orientations that young people can enact, little research exists on how children and adolescents develop consumer orientations that have relevance for adult consumer behavior. This article addresses the concept of anticipatory consumer socialization by focusing on a variety of consumer cognitions and how they are acquired.
