Do Export Support Programs Affect Prices, Quality, Markups, and Marginal Costs? Evidence From a Natural Policy Experiment
利用丹麦准自然实验，研究旨在降低非关税壁垒的出口支持政策对企业出口价格、质量、加成和边际成本的影响，发现政策仅提升出口量，未影响其他变量，支持需求转移理论。
Abstract Firms’ success in international markets depends on their product’s quality, prices, markups, and marginal cost. However, causally identified empirical evidence for the effect of trade policies that address nontariff barriers on these mechanisms is rare. To fill this gap, we exploit a quasinatural experiment in Denmark and examine the effects of an export support policy aimed at reducing nontariff barriers to trade. We find that export support raises firm-level exports within markets. However, export support does not affect prices, quality, markups, or marginal costs. Instead, the results support trade theory predicting that firms grow in export markets by shifting demand.
