However, the cotton lobby had sought and obtained the Step 2 program that paid subsidies to domestic mills and exporters that purchased upland cotton. Step 2 clearly included export subsidies that violated U.S. WTO commitments and in 2006 a WTO dispute resolution committee determined that such was indeed the case. So now the U.S. taxpayer is annually contributing $147 million to improve the productivity of the Brazil cotton industry.
You might think that the cotton lobby would have learned its lesson, but no. In 2010, as the current farm bill debate was beginning to have a real life, they dreamed up a new subsidy program called STAX (apparently not to many literary types in cotton policy circles). The cotton guys claimed that because STAX would be an “insurance” program to which farmers would contribute 20 percent of total government payments, it would be a WTO legal policy. The Brazilian government argued that STAX was just another potentially large subsidy that would expand U.S. cotton production and suppress world prices. The Brazilian government was correct, but that did not stop the House Agricultural Committee from including the STAX program in its 2012 Farm Bill proposal.
The U.S. cotton lobby might be a poster-child when it comes to seeking subsidies that are likely to violate US trade agreements, but the disease is endemic in the industry. Last week, even the American Farm Bureau, which has had a long history of advocating for free markets, came out with a new “STAX for all” farm bill proposal. In their current Farm Bill rent seeking activities, peanuts, rice and cotton farmers have sought a new Price Loss Coverage price support program that would likely trigger large subsidies, even though crop prices are at near record levels for many commodities. Corn, soybeans and wheat organizations have been seeking an expanded and potentially very lucrative “shallow loss” program. Both proposals have been included in at least one of the Senate and House agricultural committee farm bills.
Why do these proposals all pose problems for U.S. international trade relations? First, as new subsidy programs, they undercut the credibility of the U.S. as a proponent for free trade in all goods and services. Second, all of the new farm lobby proposals (STAX, shallow loss, higher price supports, and the most widely used and heavily subsidized crop revenue insurance products) increase subsidies when international agricultural commodity prices fall. As a result, they create the potential for new WTO price suppression complaints from dozens of countries on over twenty agricultural commodities, ranging from major commodities such as corn and cotton to smaller acreage commodities such as canola, sunflower, chickpeas and lentils. Third, the subsidies associated with the proposed shallow loss and price support programs are potentially so large that they could cause the US to violate its commitments to limit spending on production distorting farm programs (its “amber box aggregate measures of support). 
All this means that other countries are likely to bring more complaints against the U.S. and win the right to impose “countervailing measures”. These could legitimately include new tariffs on any U.S. agricultural exports, manufactured goods, or services. Alternatively, the U.S. can try to buy complainants off with taxpayer dollars to improve wheat production in Canada and Australia, and wine production in France and Austria, as well as cotton production in Brazil. But most seriously, perhaps, as long as congressional agricultural committees persist in ignoring U.S. trade commitments and trade relations, the U.S. government will continue to lack credibility in negotiations that open and expand new markets for all U.S. products and protect U.S. intellectual property from international theft.
