This paper is a revision of USITC Working Paper No. 2006-06-A. It represents the culmination of a lengthy research program on NTMs at the Commission which produced several earlier related papers, including Andriamananjara et al. (2004) and Dean et al. (2005). We gratefully acknowledge the help of Ted Wilson, Larry Chomsisengphet, Alla Krugylak, Shakira van Savage, Saba Zeleke, and Maya Shivakumar for their excellent work compiling data for this project. The participants in the APEC Capacity- Building Workshop on Quantitative Methods for Assessing NTMs and Trade Facilitation (October 2003), Bangkok, Thailand, the World Bank Trade Seminar (March 2004), the IMF Trade Seminar (March 2005), and the Midwest International Economics Group Meetings (April 2006) gave us many useful comments. We have also benefited from several discussions with our colleagues at the USITC. † U.S. International Trade Commission ‡ American University § Georgetown University
