The influence of board social capital on corporate social responsibility reporting

Purpose The main objective of this paper is to analyze the influence of multiple directorships, as a critical component of board social capital, on CSR reporting. This study also explores the moderating effect of certain board attributes on multiple directorships. Design/methodology/approach The authors’ sample is composed of Spanish listed firms in the Madrid Stock Exchange for the period 2011–2017. A dynamic panel data model based on the Generalized Method of Moments (GMMs) is employed. Findings Relying on a resource dependence view, the authors’ results highlight an ambiguously positive association between multiple directorships and the level of CSR reporting. In particular, this relationship is positively moderated by both board size and gender diversity. Research limitations/implications These findings contribute to academic debates concerning the value of board members intellectual capital. In particular, the authors emphasize the importance of board social capital, as well as the need to consider the context in which directors make decisions. Practical implications This evidence may prove helpful to firms when configuring the board of directors, and for regulators and professionals when refining their legislations and recommendations. Originality/value To the best of the authors' knowledge, this is the first study that empirically analyzes the impact of an important element of board social capital, such as multiple directorships, on CSR reporting, which has become crucial in financial markets.
