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

Network Overlap and Content Sharing on Social Media Platforms

Published Research

We study the impact of network overlap — the overlap in network connections between two users — on content sharing in directed social media platforms. We propose a hazards model that flexibly captures the impact of three different measures of network overlap (i.e., common followees, common followers and common mutual followers) on content sharing.Read More

Multiplex Ties and the Diffusion of Complex Innovations: Evidence from a Microfinance Intervention

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

Social Capital and Innovation: Evidence from Connected Holdings

Working Papers

In this project, I want to study the financial intermediary’s impact on firm’s innovation. More specific, I want to study whether a firm can innovate more if its shares are heavily held by connected mutual funds. Here I define a mutual fund as connected if the mutual fund managers went to the same school as the top officers of the firm.Read More

Adaptation and Social Networks in Information Technology Ventures: Evidence from a Randomized Experiment on a MOOC Platform

Working Papers

This proposal seeks to understand entrepreneurial processes, using randomized experiments from an online entrepreneurship class on MOOCs. Mentorship is widely applied in entrepreneurship education around the world. However, there are few studies examining the causal effects of mentorship as an aspect of entrepreneurship education.Read More

Connecting People for Nudges: Optimal Design of Networks to Motivate Consumer Behavior

Working Papers

An increasing number of start-ups create online and offline shared goal communities for individuals with similar goals to work towards them in the company of others. Such platforms allow individuals to connect and share effort information under the premise that it is more likely for consumers to reach their goals if they can gauge their activity in line with others’ activities.Read More

Women, Rails and Telegraphs: Information Spillovers and Collective Action

Funded Research Proposal

Social networks and media enable information diffusion in societies — and are thus at the core of collective decision making and action. The recent rise of many events which are critical for the political and corporate stakeholders, such as the Arab Spring and Occupy Wall Street, require information essential to individuals’ participation to spread among heterogeneous populations and over wide geographies.Read More

Preferences, Structure and Influence: The Engineering of Consent

Published Research

I present a decision process framework that informs the design and implementation of stakeholder influence strategy. This process combines insights from agent-based dynamic utility and dynamic network processes. Stakeholders strategically seek an outcome as close as possible to their preferred point but also wish to be on the winning side and not to pursue positions divergent from stakeholders with whom they have strong affective ties.Read More

Engineering Serendipity into Social and Knowledge Networks in Large Enterprises

Funded Research Proposal

An organization’s ability to innovate depends to a large extent on its ability to allow organizational learning to occur internally. It is not enough that knowledge gets imported into the organization; knowledge needs to also diffuse within the organization.Read More

Evolving Communication Patterns In Response to an Acquisition Event

Published Research

This study combines qualitative and quantitative methods, with particular emphasis on network data of worker behavior, to analyze changes in worker communication patterns during the first three years of a post-acquisition integration. The findings suggest that new communication routines develop slowly and are not entirely enduring even when a transformative event, such as an acquisition, occurs.Read More
