Our long run results show that children are more likely to read and study when they live with parents that are used to read. Mothers seem to be more important than fathers in this type of intergenerational transmission. Moreover, the short run analysis shows that there is an imitation effect: in the day of the survey children are more likely to read after they saw either the mother or the father reading.
Seems obvious but not less important, as Chris Blattman says. That is from this new paper by Mancini, Monfardini, and Pasqua.
