RT info:eu-repo/semantics/article T1 Business diversification and ESG engagement: Riding tandem to risk reduction and value creation? A1 Fuente Herrero, Gabriel de la A1 Ortiz Almeyda, Margarita A1 Velasco González, María Del Pilar K1 Corporate diversification K1 ESG K1 Corporate social responsibility K1 Corporate risk management K1 Firm value K1 53 Ciencias Económicas AB We examine the overlap between business diversification and environmental, social, and governance (ESG) engagement as two corporate risk management strategies, and theorise the underlying mechanisms of their interaction effect on firm value. Drawing on agency and stakeholder theories, we test our hypotheses using a sample of U.S. firms (2009–2019). Our findings indicate that ESG engagement mitigates the diversification discount. Further, ESG engagement reduces systematic risk, while diversification reduces idiosyncratic risk. However, we find no evidence supporting for the mediating role of total risk in the relationship between these strategies’ interaction and firm value. This suggests the need to explore alternative channels that may produce complementarities between these strategies.
