_Source_ : Sample consists of Current Population Surveys Merged Outgoing Rotation Group Workers for 1983-2002. Affiliate (or offshore) employment data are taken from the Bureau of Economic Analysis annual survey of US firms with multinational affiliates for the same period. Low income countries are defined according to the World Bank income categories. Import penetration and export share are taken from Bernard et al. (2006). Computer use rates are taken from October CPS supplements during the sample period. Investment good prices and total factor productivity measures, and the real price of shipments are taken from the NBER productivity database.
