No Double Standards: Quantifying the Impact of Standard Harmonization on Trade

Abstract: This paper quantifies a novel channel that contributes to greater trade integration: the release of harmonized, voluntary product standards. Standards define product characteristics that ensure compatibility, quality and consistency. Harmonized standards unify these characteristics across countries and reduce country-specific adaption costs. We create a novel database on cross-country standards and show that harmonized standards have contributed up to 13% of the growth in global trade. We build a heterogeneous firm model where harmonized standards generate scale effects and induce firms to adopt the standard. Firm-level evidence shows that only the largest firms in the top range of the size-distribution increase their export sales. These firms benefit from higher demand, charge higher prices and sell larger volumes.
