Sunstein on Valuing Childrenâs Lives
Cass R. Sunstein (Harvard Law School; Harvard University - Harvard Kennedy School (HKS)) has posted Valuing Children's Statistical Lives: A Conceptual Framework on SSRN. Here is the abstract: A longstanding puzzle for regulatory theory and practice has been the valuation of children's lives, or more precisely, the valuation of mortality risks faced by children. There is data about parents' willingness to pay (WTP) to reduce such risks, and that data might be used to produce a Valuation of Statistical Lives (VSL) for children.
