RT Article T1 The Influence of Network Exchange Brokers on Sustainable Initiatives in Organizational Networks JF Journal of business ethics VO 154 IS 3 SP 849 OP 868 A1 Saunders, Lance W.

The purpose of this paper is to expand theory on the nature of linkages between firms in a social network, specifically postulating how ties between organizations can be configured to facilitate development, diffusion, and adoption of sustainability initiatives. The theory development provides a lens with which to view the influence of a firm’s structural embeddedness in its organizational social network on developing, diffusing and adopting sustainability initiatives. The focus is on brokers who in various structural alignments help bridge the focal firm’s sustainability initiatives with distant or disconnected stakeholders the focal firm is trying to reach. The brokers help the focal firm engage these stakeholders by sharing knowledge and information regarding sustainability initiatives and by incorporating localized needs into the development of the initiatives to facilitate better diffusion and adoption. The theoretical contribution of this manuscript is a novel perspective on sustainability in organizational networks. This perspective allows for greater explanatory power regarding how organizations can achieve sustainable outcomes that meet a broad base of stakeholder needs and better facilitate sustainability initiatives across a diverse and expansive network.
