世纪经英论坛          讲座嘉宾：周恕弘（Chew Soo Hong）          讲座题目：Rice, Risk, Cooperation, and Gene x Culture Coevolution: A Gene for Social Efficiency          讲座时间：2018年6月1日（星期五）上午10点          讲座地点：明德主楼623会议室          嘉宾介绍：              周恕弘（Chew Soo Hong），新加坡国立大学讲席教授，世界计量经济学会院士（Fellow）。周恕弘教授是世界著名的实验经济学家和行为经济学家，曾执教于美国亚利桑那大学、约翰·霍普金斯大学、加州大学尔湾分校、香港科技大学（担任讲座教授）。在Econometrica, PNAS（美国科学院院刊），Journal of Economic Theory, Review of Economic Studies, Management Science等世界顶级学术期刊上发表多篇论文，2011年他当选为世界计量经济学会（Econometric Society）的院士（Fellow），是这一世界上最著名的经济学协会自1933年创建以来的第11位华人院士。周恕弘教授是公理非预期模型的先驱者之一，现今他领导的新加坡国立大学行为与生物经济学实验室和社会科学实验室致力于将基因组学、神经科学、决策理论与行为和实验经济学有机结合，在神经和分子层面上对人类决策机制获得更深层次的认识。          讲座内容介绍：              To investigate how culture induced by the irrigation-intensive rice cultivation influences people`s risk taking and cooperative behavior, we make use of several individual choice tasks and behavioral games together with 1,104 university students recruited in Beijing. We find that cooperativeness proxied by the level of contribution in the public goods game varies positively with the proportion of rice cultivation in subjects` birth province. This finding is mutually replicated in an independent study by Zhou (2017). It is further corroborated by examining survey data relating to cooperativeness from the 26,000 strong China Family Panel Studies. At the same time, we find a positive relation between the proportion of rice cultivation and risk taking. This latter finding renders a novel perspective to the reported East-West differentiation in risk attitude and together with the link to cooperativeness points to an underlying social efficiency orientation. We further identify a genetic basis for both cooperativeness and risk taking. The dopamine receptor D4 (DRD4) exon III coding region polymorphisms 2R genotypes are associated with increased cooperativeness as well as risk taking. Finally, we find evidence of a gene-culture coevolution across 12,000 years in favor of the 2R genotypes of DRD4 using province-level history on the introduction of rice farming.
