Long-lasting effects of relative age at school

We investigate the long lasting effects on behaviour of relative age at school. We conduct an online incentivised survey with a sample of 1007 adults, who were born at most two months before or after the school entry cut-off date in four Australian states. We fi nd those who were among the oldest in the classroom throughout their school years display higher self-confi dence, are more willing to enter in some form of competition, declare taking more risk in a range of domains in their life and are more trusting of other people, compared to those who were among the youngest.
