讲座标题:Railways, Telegraph and Technology Adoption: The Introduction of American Cotton in Early 20th Century China

要:We present a new source of gains from infrastructure, technology adoption. Through the lens of a heterogeneous agent model with trade and information frictions, we explore how infrastructure increases welfare through the endogenous adoption of a new agricultural technology-a high-quality variety of American cotton-in early 20 th century China. Using historical data, our empirical tests reveal that counties that had access to the railway and telegraph networks were more likely to cultivate American cotton, since these infrastructures decreased the take-up thresholds. As predicted by the model, counties that were less suitable for cultivating cotton and households with smaller farms experienced larger increases in the adoption of American cotton if they were connected to these infrastructures. The contribution of the additional technology adoption margin to the overall welfare gains from infrastructure is quantitatively large.

讲座标题:铁路、电报与技术引进:20世纪初美国棉在中国的传播

要:本文提出了基础设施收益的新来源——技术引进。通过建立包含贸易和信息摩擦的异质性代理人模型,本文探讨了20世纪初,中国的基础设施如何通过促进新的农业技术——高质量的美国棉的引入提高福利水平。基于历史数据的实证分析表明,接入铁路和电报网络的县更有可能种植美国棉,因为这些基础设施降低了技术引进的门槛。正如模型预测的,在接入这些基础设施后,棉花种植条件较差的县和拥有较小农场的家庭更倾向于引进美国棉。技术引进对基础设施带来的整体福利增益具有显著的贡献。
