Abstract
A growing body of literature focuses on the importance of peer effects for farmers adoption decisions. However, little is known on how interventions affect networks. We are analyzing network changes and the influence of peer effects on the adoption of technologies. Our analysis builds on a unique dataset that combines a randomized controlled trial (RCT) with detailed panel data on communication networks. The RCT was implemented in rural Kenya and consisted of varying combinations of agricultural and nutrition training sessions. The broader purpose of the extension training was the promotion of the black bean variety KK15. Survey data from 48 farmer groups (824 households) was collected before (2015) and after (2016) the intervention. Results suggest that the intervention had a positive impact on the creation of communication links. We find positive effects of adopting peers on individual adoption decisions. Further, peer effects become increasingly important for the adoption decision of farmers attending a higher share of training sessions. Hence, training farmer groups can be very efficient in diffusing new technologies since peer effects can stimulate and drive the adoption process. Acknowledgement : This research was financially supported by the German Federal Ministry of Food and Agriculture (BMEL) based on the decision of the Parliament of the Federal Republic of Germany (grant number 2813FSNu01).

We would like to express our special gratitude to all respondents and enumerators who were part of this survey.
