This paper addresses the question empirically and theoretically. Empirically, we tested the effects of peer interaction on the number and quality of business plans submitted in a Pan-African RCT including 5,000 entrepreneurs. Thetreatment provided the possibility of interaction in different interaction settings (face-to-face or virtual, peers being of the same or diverse nationalities). We find that, while estimated network effects are almost always strong, the treatment effect is not so and displays a non-monotone trade-off between diversity and interaction "bandwidth." We develop a model that sheds light on this behavior by differentiating between constructive and disruptive interaction. It is also qualitatively supported by our experimental evidence47engAtribución-NoComercial-SinDerivadas 3.0 EspañaSocial NetworksPeer EffectsEntrepreneurshipInnovationSemantic analysisworking paperEconomíaopen accessDT/0000002147
