Towards an integrated model for the transference of environmental responsibility

This research explores how environmental responsibility transfers to others. Although environmental responsibility is one of the most debated topics in environmental management literature, a framework describing how a teacher's environmental responsibility shapes the student's environmental responsibility is still lacking. Adopting emotional contagion theory as a lens, the paper addresses this issue via the mediation of emotional contagion and the moderation of a teacher's environmental concern. Based on a survey of teachers and students (N = 283) conducted in Pakistan, our findings provide evidence that a teacher's environmental responsibility can better transfer to students via emotional contagion. Additionally, our data establish that the transference of environmental responsibility from teachers to students via emotional contagion is more effective when the teacher has a high level of environmental concern than when he or she has a low level of environmental concern. Finally, the authors discuss the implications for policy in detail.

Consumers buying behaviour towards agri-food products: A mixed-method approach

This study aims to identify the factors that can influence consumer purchasing behaviour in the context of agri-food. Based on the Stimulus-Organism-Behaviour-Consequence theory, this study proposed a model to explain purchasing behaviour that included environmental factors as well as a set of cognitive processes. This study adopted a mixed method approach and in the first stage, a qualitative analysis was conducted to extract the constructs for the study. In the second stage, the quantitative analysis was performed by means of CB-SEM using 891 responses collected through a survey. This resulted in identifying the factors that influence agri-food purchasing behaviour. According to the findings, health consciousness and food safety concerns in the form of a stimulus have a positive relationship with agri-food image, agri-food label, and agri-food benefits acting as the organism. Similarly, the three organisms have a positive relationship with trust. Ethnocentrism is also found to have positive and significant association with trust. The combination of trust and ethnocentrism has consequences, in the form of agri-food purchase behaviour. The study's findings have significant implications for marketers and marketing strategists.

The coverage assignments of financial analysts

Previous studies document that forecast accuracy impacts analyst career outcomes. This paper investigates the influence of forecast accuracy on coverage assignments. I show that brokerage houses reward accurate analysts by assigning them to high-profile firms and penalise analysts exhibiting poor accuracy by assigning them to smaller firms. The coverage of high-profile firms increases the potential for future compensation linked to investment banking and trading commissions. In addition, covering such firms increases analysts' recognition from buy-side investors, which, in turn, increases the likelihood of obtaining broker votes and votes for the Institutional Investor star ranking. Overall, my results indicate that high forecast accuracy leads to increased future compensation.
