From the report summary: "The enacted 2014 farm bill (Agricultural Act of 2014; P.L. 113-79) could result in potential compliance issues for U.S. farm policy with the rules and spending limits for domestic support programs that the United States agreed to as part of the World Trade Organization's (WTO's) Uruguay Round Agreement on Agriculture (AoA). In general, the act's new farm safety net shifts support away from classification under the WTO's green/amber boxes and toward the blue/amber boxes, indicating a potentially more market-distorting U.S. farm policy regime. [...] Perhaps more relevant to U.S. agricultural trade is the concern that, because the United States plays such a prominent role in most international markets for agricultural products, any distortion resulting from U.S. policy would be both visible and vulnerable to challenge under WTO rules. Furthermore, projected outlays under the new 2014 farm bill's shallow-loss and counter-cyclical price support programs may make it difficult for the United States to agree to future reductions in allowable caps on domestic support expenditures and related 'de minimis' exclusions, as envisioned in ongoing WTO multilateral trade negotiations."
