A dynamic linear-in-means model is applied in order to analyse the importance of social ties for the body weight-related behaviour of US youth. The methodology shows how to estimate peer effects free of the ‘reflection problem’ in a dynamic context where individual and group-specific unobservable effects are controlled for. The results show that the main drivers for the body weight-related behaviour are past and peer effects. For individuals who were normal weight or obese during adolescence, past and peer effects are shown to be both relevant. Peer effects, instead, explain more the variation in the body mass index (BMI) for individuals who were overweight during adolescence, showing in this way the importance of social interactions for body weight-related behaviour.

This paper proposes a novel approach to address identi fication of social endogenous e ects by generalizing the methods commonly used in standard dynamic panel data analysis to the peer e ffects setting. Our methodology shows to can estimate peer e ects free of the \re "reflection problem" in a dynamic context where individual- and group-specifi c unobservable e ects are controlled for. We apply a dynamic linear-in-means model for analyzing the importance of social ties for the body-weight-related behavior of US youth. We show that the main drivers of body-weight-related behavior are habituation and imitation eff ects. For individuals who were normal-weight during adolescence habits seem to be slightly enforced by imitative behavior: in this instance, for an 1% increase in average BMI we expect about 0:6% increase in individual BMI, whereas the coe cient for past BMI is 0:4%. Imitation e ffects, instead, explain most of the variation in the Body Mass Index of individuals who were overweight and obese during adolescence, signaling the presence of a social multiplier e ffect: for these two groups an increase of 1% in average BMI leads, respectively, to an increase of 0:2% and 0:4% in current BMI.
