Self-Esteem and the Onset of Adolescent Sexual Activity}, year={2013}, month={Jan}, institution={Institute of Labor Economics (IZA)}, address={Bonn}, type={IZA Discussion Paper}, number={7171}, url={https://www.iza.org/publications/dp7171}, abstract={Self-esteem has been conceptualized as a "social vaccine". The belief is that high self-esteem can inoculate young people, against vulnerability to a wide range of social illnesses. This study gives a contribution in the understanding of the causal relation between self-esteem and sexual behaviour among American adolescents. I analyzes the impact of different levels of early self-esteem on a wide set of risky sexual behaviours. I use data from the National Longitudinal Study of Adolescent Health and I take into account the endogeneity of self-esteem using instrumental variables methods and measuring self-esteem before sexual initiation. I find that self-esteem over a certain threshold' is a protective resource for girls, delaying the onset of sexual activity, reducing the number of occasional sexual partners and increasing the likelihood of having protected sexual encounters.}, keywords={self-esteem;adolescent's sexual behaviour;Add Health;instrumental variable model}, }
