中文摘要

我们考察信息通信技术的采用如何影响双边贸易。研究背景是挪威的一项公共计划,该计划铺设宽带接入点,从而在企业获得和使用宽带方面产生了可合理视为外生的变化。我们发现,宽带使贸易模式对距离和经济规模更加敏感。这些结果与一个具有可变需求弹性的贸易模型相一致。该模型预测,采用一种能够降低信息摩擦的技术会扩大出口商和进口商的选择集,这使得需求对贸易成本、进而对距离更具弹性。(JEL D83, F14, L86, O33)

Abstract

We examine how the adoption of information communication technology affects bilateral trade. The context is a public program in Norway that rolled out broadband access points leading to plausibly exogenous variation in the availability and adoption of broadband by firms. We find that broadband makes trade patterns more sensitive to distance and economic size. These results are consistent with a model of trade with variable elasticity of demand. The model predicts that adoption of a technology that lowers information frictions enlarges the choice set of exporters and importers. This makes demand more elastic with respect to trade costs and thus distance. (JEL D83, F14, L86, O33)
