US businesses are bigger, and their workers more productive, thanks to the adoption of IT in the 1990s, according to a report from consultant McKinsey.
From 1995 to 2000, productivity in the US grew at about two per cent a year, twice the rate of the early 1990s.
About one third of the improvement in productivity growth was attributed to technology, the study said.
But it has been hard to understand technology's economic impact more precisely. One problem is that some businesses have not measured how IT equipment benefits them, the report said.
But according to the San Jose Mercury News, productivity gains from IT can hinge on non-technological factors.
Industries that change their business to fit with websites and database and customer relationship software can be more productive than those that do not.
