SIC87 1972-2005 NAICS 1989-2005 Note: These data also contain countries’ GDP per capita and so can be used to compute low-wage country import penetration as in Bernard, Jensen and Schott (2006a). They also contain cif charges and duties collected and so can be used to estimate trade costs as in that paper and in Bernard, Jensen and Schott (2006b).
