Purpose Drawing upon cohort theory, the age-period-cohort framework and the portrait value system, this paper aims to examine differences in basic human values between generations Y and Z as they are shaped by recent major events (most importantly the COVID-19 pandemic). Design/methodology/approach Hypothesized differences between values of generation Y and Z were tested using a content analysis of recent articles (Study 1) and an online survey through a prolific crowdsourcing website (Study 2). Findings This research finds that while both generations value universalism and benevolence, Generation Y is more likely to conform and follow traditions while Generation Z values stimulation, hedonism and achievement more. The top two COVID-19 concerns for both groups were the health of others and financial security. Generation Y is more concerned about the economy while Generation Z is more worried about uncertainty in their future. Research limitations/implications This paper provides insight into how the current environmental crisis has shaped the values of generations Y and Z and offers an understanding of the similarities and differences in values between these two generations. Practical implications The findings have direct implications for the design of products/services and for the creation of effective marketing communications to reach these two consumer groups. Originality/value This research is novel in identifying the basic human values of generations Y and Z as they are shaped by recent events such as the most recent economic recession and COVID-19.

PurposeThis paper provides a framework of the indicators of the quality of text in online reviews and their influence on the perceived helpfulness of reviews. First, the authors assess the effects of concreteness, readability and credibility on review helpfulness. The authors then test whether these effects change, based on review valence and readers' personality traits (specifically, extraversion and neuroticism).Design/methodology/approachThe authors conducted an online experiment in the context of hotel reviews and tested our model using Generalized Estimating Equations (GEE).FindingsThe authors' findings indicate that consumers consider all three quality features – concreteness, readability and credibility when evaluating negative reviews. However, they assess positive reviews based only on how credible they seem to be. Consumers with the personality traits of neuroticism and extraversion value different review characteristics and this difference is dependent on review valence.Originality/valueTo the authors' knowledge, this is the first study to examine the interactions between review valence and reader personality on review helpfulness. The authors' findings make important contributions to the literature on information diagnosticity and offer managerial implications related to customizing the presentation order of reviews based on their expected helpfulness for individuals with extraverted and neurotic personalities.
