Abstract: Purpose - Corporation's board (CB) is viewed as a vital internal corporate governance (CG) mechanism, playing a critical role in mitigating the agency problems and enhancing firm performance. Considering the mixed nature of extant CG literature on CB-firm performance link, this study aims to examine the impact of specific CB attributes on firm performance studied in varied contextual settings and investigates the moderating effects of three contextual factors, i.e. legal origin, industry type and firm type on CB-performance relationships. Design/methodology/approach - Meta-analysis technique suggested by Hedges and Olkin (1985) was used to analyse a sample of 330 effect sizes reported in 148 studies published between 2000 and 2020 in 85 peer-viewed journals, studying CB-performance associations across 31 countries. The analyses were conducted in two stages: first, the authors assessed the main effect of CB attributes on firm performance and tested the heterogeneity in effect size across the primary studies. In the next stage, the authors investigated the moderating variables accounting for this heterogeneity in the CB-firm performance relationship. Findings - Board independence, board diversity, board size and role duality are the CB attributes, which significantly and positively impact firm performance. Further, the homogeneity tests revealed variability in effect size for all CB attributes except for board committees. Subgroup meta-analyses revealed that the contextual factors related to industry-type and firm-type are substantial explanatory source of heterogeneity in CB-performance association, though legal origin of firm also partially explains the heterogeneity in this relationship. Research limitations/implications - Only empirical research reporting Pearson product-moment correlation coefficients(r), as the effect size, were considered for this study. Some of the other CB attributes such as board composition, compensation structure of board members, performance evaluation and appointment process of board members were not included due to limited empirical research on these attributes. Practical implications - The paper includes implications for managers and policy makers for the development of effective corporate boards and CG mechanisms. Originality/value - This paper integrates diverse empirical evidence on the associations of CB attributes with firm performance and systematically assesses the moderating factors that contributes to heterogeneity in these relationships.
