Politics, the WTO and Trade Disputes: Evidence from US Cases

Do political variables play a significant role in trade disputes and does the World Trade Organization (WTO) ameliorate disputation? This paper uses US data to assess the role of the WTO and political variables in trade disputes. The data suggest that political factors are significant in the initiation of trade disputes and in their length of adjudication. The WTO disputes that require the formation of adjudication panels take fewer months to complete than under the General Agreement on Tariffs and Trade system, but overall the WTO appears not to play a significant role in reducing the number of disputes or shortening their duration.
