世紀經英論壇          講座嘉賓：周恕弘（Chew Soo Hong）          講座題目：Rice, Risk, Cooperation, and Gene x Culture Coevolution: A Gene for Social Efficiency          講座時間：2018年6月1日（星期五）上午10點          講座地點：明德主樓623會議室          嘉賓介紹：              周恕弘（Chew Soo Hong），新加坡國立大學講席教授，世界計量經濟學會院士（Fellow）。周恕弘教授是世界著名的實驗經濟學家和行為經濟學家，曾執教于美國亞利桑那大學、約翰·霍普金斯大學、加州大學爾灣分校、香港科技大學（擔任講座教授）。在Econometrica, PNAS（美國科學院院刊），Journal of Economic Theory, Review of Economic Studies, Management Science等世界頂級學術期刊上發表多篇論文，2011年他當選為世界計量經濟學會（Econometric Society）的院士（Fellow），是這一世界上最著名的經濟學協會自1933年創建以來的第11位華人院士。周恕弘教授是公理非預期模型的先驅者之一，現今他領導的新加坡國立大學行為與生物經濟學實驗室和社會科學實驗室致力于將基因組學、神經科學、決策理論與行為和實驗經濟學有機結合，在神經和分子層面上對人類決策機制獲得更深層次的認識。          講座內容介紹：              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.
