This study uses new organic import/export data to test the hypothesis that a 2012 organic certification equivalency agreement between the European Union and the United States positively influenced U.S. trade of organic agricultural commodities. Using a difference-in-difference approach, we find that the likelihood of exporting any level of organic products to a particular E.U. country increased due to the agreement, as did the share of organic exports to the E.U. We intend to estimate the effect on organic imports from the E.U. in a similar way.
