This paper investigates the impact of highway networks on firms’ exports. The paper constructs a firm-level measure of highway access using GIS information on firm locations and highways, and adopting an instrumental variable approach. The analysis finds that improvement in highway access significantly promotes firms’ exports, after controlling for firm characteristics in addition to unobservable city and industry time-varying factors. Highway access also helps firms to expand the scope of their exports and imports. More interestingly, the positive effects of highway access on exports are stronger for less productive firms. With greater highway access, less productive firms lower their markup, but more productive firms increase their markup.
Key words: Exports, Highways, Product Scope, Markup, GIS
