项目摘要
This research project will use experimental methods to study two channels through which access to cities may cause economic and social change: markets and denser social networks. Cities are hubs of innovation and entrepreneurship, both important drivers of economic growth. However, there is little credible empirical evidence about the mechanisms behind the economic benefits of cities because urbanization occurs alongside several social and economic change. The experiments involve providing free transportation of rural dwellers to urban markets as well as urban social events. Exposure to markets has been shown to be associated with greater cooperation and more trust in anonymous strangers; two key ingredients for a successful economy. By facilitating denser social networks, cities enable the cross-fertilization of ideas and drive innovation. Reducing barriers to urban access could thus promote business relations, provide information about new opportunities, and new ideas that individuals could then bring back to their communities. This research will provide credible causal estimates of the importance of access to urban centers for rural dwellers. In doing this, it will provide evidence about the importance of these different mechanisms through which urban centers facilitate economic growth. The results of this research project will provide policy makers a mechanism to link rural areas with urban areas and thus reduce the rural-urban income differential.This research project will study the randomized rollout of a program that facilitates urban access for people living in rural areas. Implemented by an NGO, this `City Access Program' provides rural dwellers with regular weekly transportation to the nearest large city. The program has two components, which will be the `treatment arms' of the study. In the `market’ arm, the NGO provides transportation directly to the city’s central market and encourages participants to buy or sell goods there as they please. In the `social’ treatment arm, NGO provides transportation to the city along with an invitation to attend one or more of a series of social group activities, either a dancing/music group or a church group. The random assignment of participants to these treatments or to control group will allow the PIs to estimate causal effects of providing rural dwellers with greater access to the city in general—and to urban markets and social networks in particular. The project will examine how such exposure affects individuals’ economic behaviors and wellbeing, beliefs and values, psychological traits, and social interactions. The results of this research project will provide policy makers a mechanism to link rural areas with urban areas and thus reduce the rural-urban income differential.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
这一研究项目将采用实验方法,研究进入城市可能导致经济和社会变化的两个渠道:市场和更密集的社交网络。 城市是创新和创业的中心,两者都是经济增长的重要驱动力。 然而,关于城市经济效益背后的机制,几乎没有可信的经验证据,因为城市化是伴随着一些社会和经济变革而发生的。 这些试验包括为农村居民提供前往城市市场和参加城市社会活动的免费交通。研究表明,与市场的接触与更大的合作和对匿名陌生人的更多信任有关;这是成功经济的两个关键因素。通过促进更密集的社交网络,城市能够促进思想的交流并推动创新。因此,减少进入城市的障碍可以促进商业关系,提供有关新机会的信息,以及个人可以带回社区的新想法。这项研究将为农村居民进入城市中心的重要性提供可靠的因果估计。 在这样做的过程中,它将提供有关这些不同机制的重要性的证据,通过这些机制,城市中心促进经济增长。 本研究的成果将为政策制定者提供一种连接城乡的机制,从而缩小城乡收入差距。本研究将研究随机推出一项促进农村居民进入城市的方案。这一“城市交通方案”由一个非政府组织实施,为农村居民提供每周定期前往最近大城市的交通工具。该方案有两个组成部分,将作为研究的“治疗组”。在“市场”方面,该非政府组织提供直接前往城市中心市场的交通工具,并鼓励参与者在那里随心所欲地买卖商品。在“社会”治疗方面,非政府组织沿着提供前往城市的交通工具,并邀请参加一系列社会团体活动中的一个或多个,如舞蹈/音乐团体或教会团体。将参与者随机分配到这些治疗组或对照组将使PI能够估计为农村居民提供更多进入城市的机会的因果效应,特别是进入城市市场和社交网络。该项目将研究这种暴露如何影响个人的经济行为和福祉,信仰和价值观,心理特征和社会互动。 该研究项目的成果将为政策制定者提供一种机制,将农村地区与城市地区联系起来,从而减少城乡收入差距。该奖项反映了NSF的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
