Interaction Between Ethical Leadership, Affective Commitment and Social Sustainability in Transition Economies: A Model Mediated by Ethical Climate and Moderated by Psychological Empowerment in the Colombian Electricity Sector

This inquiry articulates a conceptually cohesive framework to explore the interplay between ethical leadership–affective commitment, particularly in settings characterized by socio-environmental volatility. Central to the analysis is the examination of how ethical climate functions as a psychological conduit and how psychological empowerment modulates this pathway. Empirical validation was carried out with a sample of 448 employees (175 women, 273 men) from Colombia’s electricity sector, a context where institutional fragility elevates the salience of ethical practices. The study employed structural equation modeling to test the model’s robustness. Results underscore that ethical leadership cultivates a benevolent ethical climate, which in turn reinforces affective commitment. Importantly, this sequence is not fixed but is contingent upon psychological empowerment. The influence of ethical leadership on ethical climate and especially on affective commitment is amplified when empowerment is high; likewise, the ethical climate–affective commitment link becomes more salient under elevated empowerment conditions. These findings highlight the influence of ethical dynamics in organizations. Beyond model validation, this research contributes to broader conversations on social sustainability. Ethical leadership is shown to foster organizational climates rooted in fairness, stakeholder sensitivity, and moral coherence—factors essential for long-term institutional legitimacy. In environments such as Colombia’s electricity industry, where governance infrastructures are evolving, such leadership emerges as a necessary condition for rebuilding trust and promoting shared ethical standards. Accordingly, this study advocates for the systematic cultivation of ethical leadership as a means to enhance organizational loyalty and public credibility. The theoretical model presented here offers fertile ground for cross-cultural replication and further inquiry across industries in emerging economies.
