摘要
本研究采用了Berry, Levinsohn, and Pakes (1995;(以下简称BLP)模型,以估计有机等效协议(oea)对出口国家的市场份额的影响,这些国家从2011年到2019年将有机农产品运往美国、加拿大和丹麦市场。BLP模型通过考虑未观察到的、特定产品的、农业生态的比较优势和双边贸易成本,来解释oea贸易影响的变化。BLP估计提供了一个更现实的贸易模式,表明生产和销售与市场竞争对手接近的有机农产品替代品的出口商对竞争对手与市场之间建立oea更为敏感。结果表明,进口商的OEA合作伙伴在这一市场的份额将高于非OEA合作伙伴。模拟结果表明,秘鲁将占据2019年美国23.8%的份额如果秘鲁在2017年与美国签署了OEA,秘鲁的市场份额就会下降。此外,如果墨西哥-加拿大和土耳其-丹麦的oea自2017年起生效,墨西哥和土耳其将分别获得2019年加拿大和丹麦市场的35.1%和1.8%。这些发现,连同在假设建立的OEA下其他出口商市场份额的变化,提供了对有机贸易模式的新见解,并突出了OEA进一步发展的潜力。
Assessing the impacts of equivalency agreements in international organic trade
This study employs Berry, Levinsohn, and Pakes' (1995; hereafter BLP) model to estimate the impacts of organic equivalency agreements (OEAs) on the market share of exporting countries that shipped organic agrifood products to the markets of the U.S., Canada, and Denmark from 2011 to 2019. The BLP model accounts for variations in the trade impacts of OEAs by considering unobserved, product-specific, agro-ecological comparative advantages and bilateral trade costs. The BLP estimation offers a more realistic trade pattern, showing that exporters producing and selling close substitutes for organic agrifood products with the competitors in the market would be more sensitive to the establishment of OEAs between the competitors and the market. Results indicate that OEA partners of the importer would achieve a higher share in this market than non-OEA partners. The simulation results suggest that Peru would have captured 23.8% of the 2019 U.S. market share if Peru had signed an OEA with the U.S. in 2017. Additionally, Mexico and Turkey would have secured 35.1% and 1.8% of the 2019 Canadian and Danish markets, respectively, had the Mexico–Canada and Turkey–Denmark OEAs been in effect since 2017. These findings, along with changes in the market shares of other exporters under a hypothetically established OEA, provide new insights into organic trade patterns and highlight the potential for further development of OEAs.
期刊介绍:
The American Journal of Agricultural Economics provides a forum for creative and scholarly work on the economics of agriculture and food, natural resources and the environment, and rural and community development throughout the world. Papers should relate to one of these areas, should have a problem orientation, and should demonstrate originality and innovation in analysis, methods, or application. Analyses of problems pertinent to research, extension, and teaching are equally encouraged, as is interdisciplinary research with a significant economic component. Review articles that offer a comprehensive and insightful survey of a relevant subject, consistent with the scope of the Journal as discussed above, will also be considered. All articles published, regardless of their nature, will be held to the same set of scholarly standards.
