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

Impact of Bilateral Rating Systems on Ride-Sharing Platforms

Working Papers

Bilateral rating systems impact pricing and capacity in two-sided markets. The bilateral rating mechanisms will enable customers to maintain and care for shared services, through reputational mechanisms, increasing social welfare. Read More

The Dark Side of Outsourcing: Task Scope, Vendor Relationships, and Value Creation in IT Services

Funded Research Proposal

As outsourcing expands in scope to increasingly higher-end tasks, the tension between value creation and appropriation in such inter-firm relationships raises important questions regarding the extent to which a firm should outsource activities in the value-chain and engage with its suppliers.Read More

The Dynamics of Resource Competition: Implications for Firm and Industry Components of Returns

Working Papers

How do ex ante similar firms develop heterogeneous resource positions that lead to persistent performance differences, even among direct competitors? The model in this paper shows that resource competition drives amplification of small differences in resource positions into large performance differences.Read More

Welfare Effects of Physician-Industry Interactions: Evidence from Patent Expiration

Working Papers

Many transactions occur via expert advisors, especially in the healthcare sector, and as such, firms frequently implement strategies to influence these advisors. The efficiency of these interactions is an empirical question. Read More

Startup Innovation and Corporate Venture Capital

Working Papers

Entrepreneurs are increasingly turning to established firms for venture capital, but research on how this affects their development is lacking. I argue that these relationships are particularly valuable to entrepreneurs in helping them drive their technological discoveries into development. Read More

When Time Away Sparks Time at Work: Time-Off as a Source of Competitive Advantage for Innovation

Working Papers

The management view of human capital as a source of sustained competitive advantage
has driven research on how strategic human resource practices affect organizational performance. This paper focuses on how a firm’s time-off policy can be a source of competitive advantage in entrepreneurial settings, particularly for innovation.Read More

Closer Workers, More Productive Workers? 

Working Papers

A worker’s commuting distance to the workplace may have implications for her productivity through channels such as costly travel time and reduced knowledge spillovers, and these costs may drive observed agglomerative spatial patterns previously identi fied in the literature.Read More

Change Agents Working Across Multiple Networks: Role Divergence and Microfinance Participation Among Women in 43 Indian Villages

Working Papers

Microfinance is an important method of lending to female micro-entrepreneurs in developing countries. This method leverages social influence in networks to promote program participation through central change agents in the community. Existing networks literature would suggest that central change agents should be more effective at promoting participation. Read More

Experimentation in New Ventures: Evidence from the U.S. Software Sector

Working Papers

Experimentation is the center of a fascinating debate among entrepreneurship practitioners. Inspired by the lean startup, much current practice advocates the intense use of experimentation. Conversely, a large entrepreneurship tradition emphasizes the importance of design and planning. 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

Using Machine Learning to Predict High-Impact General Technologies

Working Papers

Can machine learning techniques be used to predict high-impact, general technologies? We find that an ensemble of deep learning models that analyze both the text of patents as well as their bibliometric information can ex-ante identify such patents, accurately identifying 80 of the top 100 high generality patents in the hold-out sample.
