In this paper, we identify the economic implications of the pressure to share resources within a social network. Through a set of field experiments in rural Tanzania we randomly increased the expected harvest of a treatment group by the assignment of an improved and much more productive variety of maize. We find that individuals in this group reduced their interaction with their own network. We also find that treated individuals reduced labor input by asking fewer network members to work on their farm during the growing season and, as a result, obtained fewer harvest gains.
