Multiplex Network Diffusion

Working Papers

The networks literature examining the diffusion of complex innovations by social contagion has focused on the benefits of “multiplex” (or “wide”) ties in these processes. Multiplex ties span different types of networks to create inter-connectivity across subgraphs within a community. Read More

Influencers’ Role Complexity Moderates the Benefits of Eigenvector Centrality for Diffusion in Social Networks

Working Papers

Existing research on the diffusion of innovations has focused on the benefits of using central influencers to trigger adoption cascades in networks. Yet, prior work has not examined how influencers’ role complexity moderates these benefits. Read More

Network Multiplexity and The Spread of Complex Innovations: Evidence From a Microfinance Intervention in India

Working Papers

The purpose of this study is to examine how macro-level properties of multiplex networks, such as overlapping relations and interlocking role structures, affect the diffusion of complex innovations, those whose benefits are uncertain for a target group of adopters. Read More

Homophily and Consolidation in Intra-Firm Collaboration Networks and their Impact on Innovation Output

Funded Research Proposal

Research in management science has long posited that network structures, specifically the patterns of informal interactions among people, affect information flows and knowledge recombination. Yet, how do different network topologies affect the production of new knowledge and ideas? Read More

Modeling the Diffusion of Complex Innovations as a Process of Opinion Formation through Social Networks

Published Research

Complex innovations – ideas, practices, and technologies that hold uncertain benefits for potential adopters — often vary in their ability to diffuse in different communities over time. To explain why, I develop a model of innovation adoption in which agents engage in naïve (DeGroot) learning about the value of an innovation within their social networks.Read More
