Economic analysis of peer effects in adolescence and adulthood

虽然青少年比幼儿更健康、更强壮、更善于推理，但其发病率和死亡率是幼儿的两倍。意外伤害大多是可以避免的，但由于错误的决定，这是澳大利亚青少年死亡和住院的最大原因。同伴存在可能是青少年决策能力低下的主要原因。本项目旨在使用实验经济学方法来研究同伴存在如何影响经济决策模型的参数，特别是风险承受能力、贴现和犯错倾向。该项目旨在促进对整个生命周期决策的理解，为理论建模提供信息，并向决策者提供如何减少青少年风险的建议。

Although healthier, stronger and better at reasoning than young children, adolescents' morbidity and mortality rates are double those of young children. Unintentional injury, mostly avoidable and attributed to wrong decisions, is the biggest cause of death and hospitalisation among adolescents in Australia. Peer presence is likely to be a major cause of adolescents' inferior decision-making. This project aims to use experimental economics methods to study how peer presence affects the parameters of the economic decision model, specifically risk tolerance, discounting, and propensity to make errors. The project aims to advance the understanding of decision-making across the lifespan, inform theoretical modelling and advise policy-makers how to reduce the risks to adolescents.
