Organizational Change and the Dynamics of Innovation: Formal R&D Structure and Intrafirm Inventor Networks

Working Papers

Prior studies have shown associations between organizational structure and innovation. However, most have been static and cross sectional, only showing variation across firms. This gap is problematic because it is not clear if firms can use structure as a lever to direct their research outcomes.Read More

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

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

Optimal Network Design for Inducing Effort

Working Papers

Many companies create and manage communities where consumers observe and exchange information about the effort expended by other consumers. Such communities are especially popular in the areas of fitness, education, dieting, and financial savings. 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

Women, Rails and Telegraphs: An Empirical Study of Information Diffusion and Collective Action

Working Papers

How do social interactions shape collective action, and how are they mediated by the availability of networked information technologies? To answer these questions, we study the Temperance Crusade, one of the earliest instances of organized political mobilization by women in the U.S. 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

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

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

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
