We explore the effect of bullying at school on the educational attainment of a sample of individuals drawn from the British National Child Development Study (NCDS). Our empirical findings suggest that school bullying has an adverse effect on human capital accumulation both at and beyond school. Moreover, the impact of bullying on educational attainment at age 16 is found to be similar in magnitude to class size effects. Furthermore, in contrast to class size effects, the adverse influence of bullying on educational attainment remains during adulthood. In addition, being bullied at school influences wages received during adulthood as well as indirectly influencing wages via educational attainment. (Contains 2 figures and 5 tables.)
