The sustainability reporting-firm performance nexus: evidence from a threshold model

Purpose This study aims to provide a convincing argument behind the mixed findings on the association between sustainability reporting and firm performance by investigating the possibility of a non-linear relationship through a threshold model. Design/methodology/approach This study used (Hansen's 1999) threshold framework to investigate the relationship between firm performance and sustainability reporting using a sample of 210 Bombay Stock Exchange-listed firms spanning over 10 years from March 2010 to March 2019. This framework helps to test the threshold effect's presence, estimate the threshold value and check the authenticity of the estimated threshold value. Findings Sustainability reporting has a differential threshold impact on the different indicators of firm performance. On the one hand, the authors' results illustrate that the firms' operating performance is positively impacted if and only if the sustainability reporting crosses a certain threshold. On the other hand, sustainability reporting positively impacts firms' market performance only up to a cut-off point. Practical implications Managers should strive to balance sustainability reporting to reap its desired benefits on firm performance. Originality/value This study explores the possible non-linearity in the association between firm performance and sustainability reporting and explains the relationship's inconclusive results. Further, this study explores the field in the novel emerging economy with unique institutional settings that mandate spending on sustainability activities.
