This paper focuses on young adults in the US living with their parents and studies the role of peers. Using data from the National Longitudinal Study of Adolescent Health we analyse the influence of high school friends on the nest-leaving decision of young adults. We achieve identification by exploiting the differences in the timing of leaving the parental home among peers, the individual-specific nature of the peer groups, and by including school and grade fixed effects.

Our results indicate that there are statistically significant peer effects on the decision of young adults to leave parental home. This is true even after we control for labour and housing market conditions and for a comprehensive list of individual and family-of-origin characteristics that are not usually observed by the econometrician.

We discuss various mechanisms and we confirm the robustness of our results through a placebo exercise. Our findings correspond with the increasing trend of young adults living with their parents that has been observed in the US during the last 50 years.
