Improving Preferential Market Access through Rules of Origin: Firm-Level Evidence from Bangladesh
研究了欧盟普惠制原产地规则修订对孟加拉国服装企业的影响，发现原产地规则使优惠幅度削减了四分之三，而放宽规则促进了企业收入增长，主要通过扩大出货量和提升质量实现。
In countries where there exist limited opportunities to source inputs locally, rules of origin undermine access to preferential trade agreements for final goods exporters. I analyze the 2011 revision to the rules of origin associated with the European Union’s Generalized System of Preferences, which allowed apparel producers in least developed countries to use internationally sourced textiles in exported products. Using transaction-level data on Bangladeshi apparel firms, I find that the rules of origin effectively cut the preferential margin by three-fourths. Liberalizing the rules of origin resulted in firm-level revenue growth, which was driven by the intensive margin through increased shipment sizes and quality upgrading.
