Can peer interaction foster entrepreneurship in large-scale environments? We first address this question empirically through a pan-African RCT involving nearly 5,000 entrepreneurs from 49 countries where treated subjects interacted either in-person or virtually. Our analysis reveals a trade-off between interaction “bandwidth” and scalability, which is effectively addressed only if virtual interaction operates under significant but moderate peer diversity. Network-based peer effects are, however, estimated positive in all virtual arms. To explain this counterintuitive contrast, we develop a theory, supported by the evidence, that differentiates constructive from disruptive influence and also structurally identifies when scalable (hence impactful) interaction is fruitful.
