An Analysis of the Effects of Board Relations Network Structure in Determining Labor Investment Efficiency: The Monitoring Role of Institutional Owners

The purpose of this paper was to investigate the effects of board relations network structure on labor investment efficiency. Besides, the role of institutional owners in these relationships was studied. This paper had a quantitative approach based on graphic techniques. The sample included 117 companies in Tehran Stock Exchange (TSE) from 2009 to 2020. The social network analysis and regression analysis approaches were used to conduct the research tests. Evidence showed that the indicators of the degree (negative effect) and closeness (positive effect) of board relations network structure affect labor investment efficiency. In addition, monitoring of institutional owners can have a positive effect on labor investment efficiency. The intensity of the relationship between the degree index and labor investment efficiency depends on the level of this variable. Moreover, the negative relationship between over-investment in labor and the betweenness index depends on the level of institutional owner monitoring.
