Prior social ties and the limits of peer effects on startup team performance’
Strategic Management Journal 40(9) (with Rembrand Koning) We conduct a field experiment at an entrepreneurship bootcamp to investigate whether interaction with proximate peers shapes a nascent startup team’s performance. We find that teams whose members lack prior ties to others at the bootcamp experience peer effects that influence the quality of their product prototypes. A…

Conversations and idea generation: Evidence from a field experiment
Research Policy, 48(9) (with Rembrand Koning) When do conversations lead people to generate better ideas? We conducted a field experiment at a startup bootcamp to evaluate the impact of informal conversations on the quality of product ideas generated by participants. Specifically, we examine how the personality of an innovator (openness to experience, capturing creativity) and…

Helpful behavior and the durability of collaborative ties
Organization Science (with Sampsa Samila and Alexander Oettl) Long-term collaborations are crucial in many creative domains. Although there is ample research on why people collaborate, our knowledge about what drives some collaborations to persist and others to decay is still emerging. In this paper, we extend theory on third-party effects and collaborative persistence to study…

Peers and network growth: Evidence from a natural experiment
Management Science, 61(10), 2536-2547. (with Surendrakumar Bagde) Much research suggests that social networks affect individual and organizational success. However, a strong assumption underlying this research is that network structure is not reducible to the individual attributes of social actors. In this article, we test this assumption by examining whether interacting with random peers causes exogenous growth…

Specifically, we study how college students’ peers affect academic performance. Building on existing research, we consider the different types of peers in the academic context and the various mechanisms through which peers affect performance.…

Group based trajectories of network formation and dynamics
Social Networks, 34(4), 506-514. In this paper, we propose the application of a semi-parametric statistical methodology called Group-Based Developmental Trajectory Analysis to studying the dynamics of social networks. We begin with a discussion of theoretical problems in network analysis that may benefit from this approach. Next, we describe the methodology and how it can be applied…
