    Hidden Trade Costs? Maximum Residue Limits and U.S. Exports of Fresh Fruits and Vegetables
    Hejazi, Mina; Grant, Jason H.; Peterson, Everett B. (Center for Agricultural Trade, 2018-07)
    Consecutive rounds of trade negotiations at the multilateral and regional level have resulted in significant reductions to agricultural tariffs. However, agricultural economists and policy makers alike agree that non-tariff measures (NTMs) are more obscure in nature and have the potential to be more trade distorting. Among the list of NTMs, Sanitary and Phytosanitary (SPS) measures play an influential role in agri-food product trade. In this article we focus on a specific type of SPS measure known as maximum residue limits (MRLs) that features prominently in multilateral and regional trade negotiations. The purpose of this research project is threefold. First, we construct a comprehensive database of country-and-product specific MRLs for global fresh fruit and vegetable trade that varies by pesticide chemical type: herbicides, insecticides and fungicides. Second, we develop a new index summarizing the extent of bilateral MRL stringency between importing and exporting countries on pesticide tolerances focusing specific attention on the U.S. and its bilateral trading partners. Third, formal econometric models are developed to quantify and test the degree to which more stringent MRL standards in importing countries as compared to comparable domestic standards that exist in exporting countries restrict fresh fruit and vegetable trade. The results suggest importer MRL standards that are stricter than exporter MRLs can impart significant reductions in bilateral fresh fruit and vegetable trade.

    Trade impact of maximum residue limits in fresh fruits and vegetables
    Hejazi, Mina; Grant, Jason H.; Peterson, Everett B. (Elsevier, 2022-01)
    Interfering maximum residue limits (MRLs) for pesticides with agricultural trade is becoming important for food and trade policies in the early 21st century. Differing levels for pesticide residues among countries have the potential to disrupt trade significantly. We employ a non-linear and disaggregated stringency index to quantify the degree of regulatory heterogeneity levels for pesticides between trading nations for fruits and vegetables in 2013 and 2014 and investigate the trade-restricting nature of this measure using the structural gravity framework. Our findings indicate that stricter importer MRLs reduce bilateral trade to the tune of 8.8%. Looking closer at MRLs with US partners, the effect of stricter MRLs is quite elastic concerning its impact on the US -EU trade. In particular, the estimates imply that a more stringent MRL's policy decreases the US export of fruits and vegetables to the EU members by a striking 13.8%. At the disaggregated level of MRL indices over different classes of chemicals, the results indicate that there is a significant gap in regulations regarding MRLs among several major US foreign markets for fruits and vegetables, particularly in the EU and the Trans-Pacific trading partners.
