The present study integrates the extended theory of planned behaviour (TPB) model and stimulus-organism-response (S-O-R) framework to test the serial mediation effect of green satisfaction and green trust between green perceived quality and green purchase intention. Data was collected, from professionals in the field of information technology (IT) who use green energy efficient products, using a structured questionnaire. The questionnaire was circulated among 540 members of the target population and 469 usable responses were obtained. The results of partial least square structural equation modelling (PLS-SEM) showed that green satisfaction and green trust serially mediate the relationship between green perceived quality and green purchase intentions. The implications, limitations and scope for future work are discussed in the present paper.

Background The study investigates the influence of antecedents of the theory of planned behaviour (TPB) and personality traits on entrepreneurial intention and behaviour among engineering students in an emerging economy. It employs the extension of the TPB model by focusing on the intention-behaviour gap, an under-researched area in research. Furthermore, it investigates the moderating effect of entrepreneurial motivation on the relationship between intention and behaviour to improve conceptual model predictability. Methods A structured questionnaire was used to gather data from 1,564 engineering students, and the data were analyzed using structural equation modelling (SEM) with Amos software. Results The results revealed that subjective norms were the strongest predictor of entrepreneurial intention and behaviour, followed by entrepreneurial alertness, perceived behavioural control, attitude towards entrepreneurship, need for achievement, and risk tolerance. Moreover, the moderation analysis showed that entrepreneurial motivation was crucial in moderating the relationship between intention and behaviour. Conclusions The present conceptual model contributes to the existing TPB model by improving predictive power to understand the intention-behaviour relationship. The results of the study will assist policymakers, academicians of higher education institutions, and universities in developing policies, strategies, and curricula to engage more students in entrepreneurial activities.
