Notes:
Trade data from U.N. Comtrade have been cleaned using the procedure of Feenstra et al. (NBER Working Paper no. 11040, January 2005), and coverted from HS 6-digit codes to sic87dd codes using a crosswalk provided at www.ddorn.net/data.htm. Import values (variable "imports") are reported in nominal dollars.
