Board diversity and corporate propensity to R&D spending
基于英国非金融公司2005-2018年数据，研究发现董事会整体多样性与认知多样性能显著提升企业研发支出，但人口统计多样性影响不显著，且会削弱认知多样性的正面作用。
Drawing on collective contributions and group performance perspectives, this paper examines the role of board diversity in firms' R&D investment decisions. Building on a fault-line argument about a team's demographic attributes, this study also decomposes the impact of demographic and cognitive diversity on R&D spending. The study sample contains UK data of non-financial companies covering the period between 2005 and 2018. We employ panel data analysis techniques and control for potential endogeneity issues through the application of the two-step system Generalised Method of Moments (GMM) estimations. The findings demonstrate a positive and significant relationship between board diversity and level of corporate R&D spending. The findings also show cognitive diversity as significantly positively associated with corporate R&D investments. Demographic diversity, however, has an insignificant relationship with corporate spending on R&D. The results further show that demographic diversity negatively moderates the relationship between cognitive diversity and spendings on R&D. The outcome of our main findings document that as a group, corporate boards take decisions of strategic importance such as spending on R&D investment. The findings on sub-dimensions of board diversity imply that as compared to demographic diversity, functional/cognitive diversity is more relevant to strategic decisions and related outcomes. The study has practical implications for shareholders in documenting the importance of board diversity, and policy implications for regulators in highlighting the separate roles of behavioural and cognitive diversity in shaping firms' strategic investment decisions.
