The impact of board and audit committee characteristics on voluntary disclosure: a meta-analysis

Research output: Contribution to journalArticle

In this paper we apply meta-analysis to a sample of 64 empirical studies to identify the potential moderators to the relationship between board, audit committee characteristics and voluntary disclosure. We examine whether the results are affected by the differences in the construction of disclosure index, the type of voluntary disclosure, the method of disclosure, the definitions of variables relating to corporate governance, the level of investor protection, and country geographic location. We find that, whilst board size, board composition and audit committee have a significant positive effect on voluntary disclosure, CEO duality has a significant negative effect. In addition, country geographic location moderates the association between board size, board composition, CEO duality and voluntary disclosure. Furthermore, the association between CEO duality and voluntary disclosure is moderated by disclosure type, disclosure method and the level of investor protection. Finally, differences in the definitions of explanatory variables moderate the association between board composition and voluntary disclosure. We conduct a sensitivity analysis which provides evidence that, in respect of the time period, prior to 2002, CEO duality has a significant negative effect on voluntary disclosure and has an insignificant effect for the period thereafter.
