The paper examines the opportunities in and possibilities arising from Big Data in retailing, particularly along five major data dimensions -data pertaining to customers, products, time, (geo-spatial) location and channel. Much of the increase in data quality and application possibilities comes from a mix of new data sources, a smart application of statistical tools and domain knowledge combined with theoretical insights. The importance of theory in guiding any systematic search for answers to retailing questions, as well as for streamlining analysis remains undiminished, even as the role of Big Data and predictive analytics in retailing is set to rise in importance, aided by newer sources of data and large-scale correlational techniques. The Statistical issues discussed include a particular focus on the relevance and uses of Bayesian analysis techniques (data borrowing, updating, augmentation and hierarchical modeling), predictive analytics using big data and a field experiment, all in a retailing context. Finally, the ethical and privacy issues that may arise from the use of big data in retailing are also highlighted.2

The use of celebrity endorsements varies across countries; does their effectiveness similarly vary across cultures? The authors propose that power distance beliefs (PDB), a cultural orientation related to the extent to which people expect and accept differences in power, moderate the effects of celebrity endorsements. A positive effect of celebrity endorsers on evaluations of advertising should be more potent with greater PDB; source expertise and trustworthiness likely underlie this effect. To test the hypotheses, the authors use moderated mediation analyses, with corrections for measurement error and endogeneity of the mediators (source expertise and trustworthiness). The results of three studies, using both manipulated and measured PDB for respondents in different countries and with a variety of endorsers, demonstrate that PDB determine the effectiveness of celebrity endorsements on attitudes toward the advertisement and the brand. In support of the moderated mediation model, perceptions of source expertise and trust mediate the effect of celebrity endorsements, conditional on PDB. The results hold for nondurables but do not generalize to durable products.

Recently, safety incentive programs have been under scrutiny by the US Occupational Safety and Health Administration for their effectiveness to improve construction safety performance. Most of the previous research on construction safety incentives focused on anecdotal evidence examining the merits and demerits of safety incentives. Meanwhile, the long-term effect of safety incentive programs on construction safety remains uncertain. This research examined how key safety performance indicators changed over time in the presence of safety incentive programs in the US construction industry using primary survey data. The paper's key finding is that the effectiveness of safety incentive programs does diminish with time, as suspected by earlier experts and managers in the US construction industry.Construction, incentive, safety, personnel management, motivation,
