Can Institutional Investor-Manager Interactions Mitigate the Bullwhip Effect? Evidence from China

In this paper, we examine how institutional investor-manager interactions affect the bullwhip effect in corporate supply chains from the perspectives of information transmission and managerial learning. We find that increased institutional investor-manager interactions lead to a reduction in the bullwhip effect. These mitigation effects are realized through three mechanisms: improving the public information environment within the supply chain, disseminating private information, and directing managerial attention to supply chain issues. Additionally, we confirm the mediating role of information environment improvements in institutional investor-manager interactions in mitigating the bullwhip effect. Further analyses show that this mitigating effect are more pronounced in firms with a higher managerial willingness of learning, non-state-owned ownership, suboptimal inventory management quality, or lower supplier concentration.
