Exploiting a 1960s government trial in Copenhagen, we study the long-run and inter-generational effects of preventive care for toddlers. We combine administrative data with handwritten nurse records to document universal treatment take-up and positive health effects for treated children over the...

We study the impact of targeted high quality preschool over the life cycle and across generations, and examine its interaction with a health intervention during infancy. Using administrative data from Denmark together with variation in the timing of program implementation between 1933 and 1960,...

While a large literature studies the impact of exposure to early-life investment policies, this paper examines the impact of changes within a program, the Danish nurse home visiting program, on child and maternal health. We exploit variation induced by a nurse strike, which resulted in families...
