Torfinn Harding and Beata Javorcik on FDI and export unit values:

This study presents evidence suggesting that attracting inflows of FDI offers potential for upgrading a country’s export basket. The empirical analysis relates unit values of exports measured at the 4-digit SITC level to data on sectors treated by investment promotion agencies as priority in their efforts to attract FDI. The sample covers 116 countries over the period 1984-2000. The findings are consistent with a positive effect of FDI on unit values of exports in developing countries. However, such a relationship is less evident in developed countries. These results suggest that FDI can help bridge gaps in production and marketing techniques between developing and high income economies.
