Large shareholders, control contestability and firm productive efficiency

This paper investigates the effect of the largest controlling shareholders on firm productive efficiency. Using a sample of French listed firms, we employ parametric (linear regression), semi-parametric (Olley and Pakes) and non-parametric (Data Envelopment Analysis) approaches to estimate productive efficiency. We find a negative association between the excess control rights of dominant owners and firm productive efficiency, indicating that their private benefits of control prevent them from favoring productive projects. Our findings withstood several sensitivity and endogeneity tests. Additional analysis shows that multiple large shareholders, beyond the controlling owner, play a governance role that neutralizes the effect of excess control on productive efficiency.
