Service Offshoring and Productivity: Evidence from the US

The practice of sourcing service inputs from overseas suppliers has been growing in response to new technologies that have made it possible to trade in some business and computing services that were previously considered non-tradable. This paper estimates the effects of offshoring on productivity in US manufacturing industries between 1992 and 2000. It finds that service offshoring has a significant positive effect on productivity in the United States, accounting for around 10 per cent of labour productivity growth during this period. Offshoring material inputs also have a positive effect on productivity, but the magnitude is smaller accounting for approximately 5 per cent of productivity growth.
