We investigate the relation between common institutional ownership on the supplier-customer relationship and the supplier’s earnings management. We find that the common ownership significantly reduces the supplier’s discretionary accruals. This effect is more pronounced for firms with lower information transparency and higher market threat. Moreover, there is no trade-off between discretionary accruals and real earnings management for such firms. Instead, we find that the common ownership reduces the supplier’s real earnings management as well. This effect is concentrated on the firms with poor governance. To establish causality, we use an instrument constructed around a shock to common ownership following a large mutual fund scandal and find robust results. Overall, our results provide evidence that common ownership in supplier-customer relationship reduces corporate earnings management.
