Does Gender Diversity Influence Business Efficiency? An Analysis from the Social Perspective of CSR

Abstract

Gender-related corporate social responsibility (CSR) practices are receiving increasing attention from all stakeholders, as the commitment to achieving equal opportunities for women has become a top priority. However, the reality is that women remain under-represented at the most senior corporate level, and there is a lack of knowledge about many of the implications this situation entails. This study aimed to provide the first analysis of the direct effect and the indirect effect (through leverage) of board gender diversity on business efficiency. The stochastic frontier approach was used to estimate efficiency. Possible determinants were studied using a fixed effects model with instrumental variables to correct for endogeneity problems. A sample of 91 Spanish listed companies was selected. Data were gathered for the period 2004 to 2015. This period is of great interest because it spans two different contexts in terms of gender legislation. The key findings are that promoting gender diversity is important to boost efficiency and that it is vital to consider possible indirect effects such as the role of leverage.
