Thus, it is important for policy to consider how much scope...

Productivity differences can explain differences in economic growth across countries. It has been demonstrated that the presence of a foreign-owned multinational enterprise (MNE) in a developing country is one of the most important methods through which technology transfer occurs. This presence could be in the form of foreign direct investment (FDI), licensing, or imports from the developing co...

Our results suggest that domestic firms exp...
