Abstract:	Managing business relationships is challenging. While research indicates that a significant part of the variance in firm profitability is explained by the network of which the firm is a part, business partners do not always behave as expected. A firm may even be held responsible and experience boycotting by customers for not only its own, but also for its suppliers’ (unsustainable) behaviors and other incidents upstream in the supply chain. Consequently, managing buyer-supplier relationships is a central part of addressing supply risks, that is to manage the probability of incidents associated with inbound supply from individual supplier failures or the supply market, and their outcome. This dissertation investigated contemporaneous issues and relevant gaps in the risk and disruption management of buyer-supplier relationships. The three main sections revolve around enhancing transparency in supply relationships, insights into force majeure issues and related disruptions, as well the interrelation of supplier performance, disruption frequency, and disruption duration. After delineating the main academic contributions and managerial recommendations, the dissertation highlights promising future research opportunities in proactive and reactive approaches in risk and disruption management of buyer-supplier relationships.
