Product Standards and Margins of Trade: Firm-Level Evidence Product Standards and Margins of Trade: Firm-Level Evidence

Overview & Synopsis

This paper considers the heterogenous trade effects of restrictive Sanitary and Phyto-Sanitary (SPS) measures on exporters of different sizes, and the channels via which aggregate exports fall: firm participation, export values and pricing strategies. We do so by matching a detailed panel of French firm exports to a new database of SPS regulatory measures that have been raised as of concern in the dedicated committees of the WTO. By using specific trade concerns to capture the restrictiveness of product standards, we focus only on standards that are perceived as trade barriers. We analyze their effects on three trade-related outcomes: (i) the probability to export and to exit the export market (the firm-product extensive margin), (ii) the value exported (the firm-product intensive margin), and (iii) export prices. We find that SPS concerns discourage the presence of exporters in SPS-imposing foreign markets. We also find a negative effect of SPS imposition on the intensive margins of trade. These negative effects SPS are attenuated in larger firms.
