We find that, post 2000, TFP originating from the IT-Producing sector decelerated relative to the IT boom, but still accounted for 40% of aggregate productivity growth. This deceleration was counterbalanced by the contribution from IT-Using sectors, which buoyed aggregate TFP growth to almost the same rate as the 1995-2000 period. For aggregate GDP, the contributions to the growth rate of 2. 8% during 2000-2007 were: capital input (1.7% points), labor input (0.4) and TFP (0.7).
