Towards a Causal Theory and Test of Network Effects: Structural Holes, Alliance-Network Externalities, and Organizational Innovation

Working Papers

We investigate whether the effect of network position on innovation is causal or spurious. Although empirical evidence demonstrates that certain structural positions in alliance networks (e.g. structural holes) affect firm innovation, it is hard to disentangle the factors allowing a firm to put itself in a certain position from the innovation outcomes that stem from being in that position.Read More

Field Experiments to Measure the Impact of Solar Lights at the Bottom of the Pyramid

Funded Research Proposal

Providing access to cleaner and cheaper lighting solutions is necessary to lift people out of poverty. The magnitude of the economic, health, and educational impacts created by these lighting solutions as we move up the energy ladder, however, is not clear.Read More

A Machine Learning Approach To Likeable, and Memorable Brand Slogans

Funded Research Proposal

We propose to develop and validate a model that uses automatically extracted, high-dimensional sentence embeddings to predict the likeability and memorability of new and existing slogans.Read More

The Positive Effects of Sharing Innovation Successes and Failures

Funded Research Proposal

We postulate that interventions to increase sharing of failures can boost learning, increase the likelihood of creating a learning culture, and increase trust and reciprocal information sharing among teams and consumers. Further we examine the positive effects of sharing failures on interpersonal and in-group/out-group interaction at different stages of relationship (e.g., initial formation and stable relationship) and the effects on repeated interaction (e.g., a future relationship).Read More

How Do Job Candidates’ Salary Expectations Affect Firms’ Hiring Evaluations?

Funded Research Proposal

Firms often ask workers to indicate their salary expectations when they are applying for jobs. But, we currently have a limited understanding on how these salary expectations affect firms’ evaluation of the candidate: do firms evaluate candidates with low or high salary expectations more favorably? The goal of this research is to enrich our understanding of the labor market by elucidating the relationship between workers’ salary expectations and hiring evaluations.Read More

Mergers and Innovation: Evidence from the Pharmaceutical Industry

Funded Research Proposal

For this project, we will look at how innovation, measured by phase 3 failures during the FDA approval process, motivates drug companies to acquire competitors and, in doing so, how this subsequent M&A activity affects future successes in the pharmaceutical pipeline.Read More

Insider vs. Outsider Judgments of Diversity in Organizations

Funded Research Proposal

We propose that an important hurdle preventing organizations from diversifying is their ability to accurately diagnose a lack of diversity in their ranks in the first place. Specifically, we theorize that people who belong to or create groups within organizations (organizational “insiders”) perceive those groups to be more diverse than outside observers (organizational “outsiders”).Read More

The Welfare Value of Online Review Aggregators: Internet, Search Frictions and the Restaurant Industry in France

Funded Research Proposal

The main aim of this project is to understand how online aggregators such as TripAdvisor or Yelp have impacted competition in the restaurant market, and whether and how much they have benefited consumers.Read More

Innovating Finance for Social Impact

Funded Research Proposal

The need for impact measurement harmonization is a common refrain among impact investors. However, instituting standards and common frameworks requires an awareness of the constraints under which impact investors operate in their day-to-day work.Read More

How you Tweet Matters: Optimal Social Media Strategy for Startup Lifecycle

Funded Research Proposal

With over 2.7 billion monthly active users on Facebook and 330 million on Twitter , social media provide an indispensable channel for information, offering unprecedented ability to efficiently broadcast information about goods and services, especially for early-stage companies which usually lack a public channel for information disclosure.Read More

Social Media and Content Regulation

Funded Research Proposal

A significant challenge that online social media platforms such as Facebook and Twitter face today is acting as the custodians of the Internet while at the same time being the center of self-expression and user-generated content.Read More

Collaborative Experience, Collaborative Performance and Subsequent Independent Operations: Evidence From the Global Aircraft Manufacturing Industry

Working Papers

This study examines the extent to which firms that are collaborating with other firms in a particular area of business subsequently change modes of governance and undertake independent activities in the same area of business. Read More

Understanding the Relationship between Divestitures and Innovation

Working Papers

Few studies have examined the impact of divestitures on the innovation performance of firms. In particular, little attention has been paid into how the divestiture of firms’ non-core businesses could influence the innovation outcomes of their core businesses. Read More

Experimentation and Appropriability in Early-Stage Ventures: Evidence from the U.S. Software Industry

Working Papers

This study examines the tension between learning and appropriability in the experimentation process of early-stage ventures. I build a stylized model to argue that, when formal intellectual property is weak, the learning benefit of experimentation may be offset by its imitation risk. Read More
