Heterogeneity influences the transmission of information among group members. By conducting a survey of mothers with children in kindergartens, we examine whether heterogeneity among mothers influences the degree of information exchange in the classroom. We find that mothers exchange information less frequently when there is a larger difference in their ages. Further, we find that wealthy and well-educated mothers utilize information more intensively. The results suggest that the characteristics of mothers determine the ability of social learning.
