Purpose -This paper aims to describe what facilitates small and medium-sized suppliers in participating in green supply chain initiatives. These initiatives are inter-organizational initiatives attempting to improve environmental performance throughout the entire supply chain. This paper seeks to examine buyer green supply chain management practices, government involvement, and internal readiness of the suppliers themselves, as possible drivers. Design/methodology/approach -The research framework and hypotheses were examined by using a mail survey conducted in South Korea in 2005. The empirical analysis used data from 142 small and medium-sized suppliers. Validity and reliability of the scales for the construct of interest were assessed through a factor analysis and Cronbach-alpha test. To test the hypotheses for the drivers of suppliers' willingness to participate in green supply chain initiatives, hierarchical linear regression was adopted. Findings -The study finds that buyer environmental requirements and support were positively linked to their suppliers' willingness to participate in green supply chain initiatives. The government can play an important role in motivating these suppliers. Finally, the paper reveals that the more slack resources and organizational capabilities suppliers had, the more willingly they were to participate in those initiatives. Originality/value -This research is one of the few studies which explore the drivers of participation in green supply chain initiatives by considering small and medium-sized suppliers and their most important stakeholders, including buyers and the government.

This study analyzes whether narcissism in chief executive officers (CEOs) affects firm value through the promotion of corporate social responsibility (CSR) initiatives. Employing the upper‐echelons perspective, we present a research framework for the relationship between CEO narcissism and firm performance with CSR as the mediation variable. The results of the regression analysis of 265 firm‐year South Korean samples from 2010 to 2016 indicate that CEO narcissism promotes CSR initiatives and CSR enhances firm value in the capital market. However, the results do not provide evidence that CSR mediates the link between CEO narcissism and desirable organizational outcomes. The findings of this study build a better theoretical and practical understanding of the antecedents and consequences of CSR from the CEO's psychological personality perspective.
