Purpose – This study aims to incorporate macro- and micro-level institutional factors into the theory of planned behaviour (TPB) model to understand their effect on entrepreneurial intentions (EI) amongst students in nations from Latin America and Caribbean region and India. Design/methodology/approach – Using non-probability sampling technique, data was collected from Colombia, Dominican Republic, India and Mexico, and consisted of 757 useable responses from students. Structural equation modelling was employed to conduct confirmatory factor analysis while path analysis was used to test the hypotheses. Findings – Combined samples from all countries showed information and communications technology infrastructure, usage and adoption (ICTi) and educational support had an indirect effect on EI through personal attitude (PA) and perceived behavioural control (PBC) but not through subjective norms (SN). Additionally, it was found that while PA and PBC have a direct influence on EI; SN does not. Further, an inverse relationship was found between age and EI, while respondents’ gender, academic programme and entrepreneurship education had no significant effect on EI. Practical implications – This study suggests enhanced investments in developing and emerging economies by enabling institutional environments at the macro- and micro-level that could help promote EI. Originality/value – The current paper contributes to the EI literature by incorporating institutional factors at macro- and micro-levels in developing and emerging economies towards a more integrative TPB.
