Emily Oster is driven by data. An economics professor who often applies a risk-analysis lens to things like parenting, she wants to give you the numbers and let you decide.

Her new book, “The Family Firm,” picks up were “Cribsheet” left off. It equips parents to make decisions for their elementary kids using data and looking at evidence. Topics she tackles include schooling, nutrition, discipline and screen time.

Oster joined host Kerri Miller to talk about her book, her approach to parenting and how to use evidence to make decisions.
