Aflatoxin redux: Does European Aflatoxin regulation hurt groundnut exporters from Africa?
实证检验了2002年欧盟黄曲霉毒素最大残留限量标准的收紧对非洲花生出口的影响，发现该标准并未显著阻碍出口，国内供应能力才是主要制约因素。
We provide an ex-post econometric examination of the harmonization and tightening of the EU Maximum Residues Limit (MRL) on aflatoxins in 2002, and its impact on African exports of groundnut products. We show that the MRL set by the EU has no significant trade impact on groundnut exports from Africa across various methods of estimation. African domestic supply plays an important role in the determination of the volumes of trade and the propensity to trade. Our findings suggest that the trade potential of African groundnut exporters is more constrained by domestic supply issues rather than by limited market access.
