In this sexcerpt from their book, "Love, Money, and Parenting: How Economics Explains the Way We Raise Our Kids," Matthias Doepke and Fabrizio Zilibotti discuss the phenomenon of helicopter parenting, in which parents spend more time monitoring their kids' activities. They present empirical evidence for a rise in parental involvement and suggest that greater income inequality and the related higher stakes surrounding children's educational success may be driving parents to be more attentive.
