These data contain countries’ GDP per capita, and so can be used to compute low-wage country import penetration as in Bernard, Jensen and Schott (JIE 2006), as well as cif charges and duties collected. and so can be used to estimate trade costs as in that paper and in Bernard, Jensen and Schott (JMS 2006). I am no longer updating these data.
