We examine the effects of information technology (IT) labor on productivity using data from U.S. private industries. Our results suggest that IT labor is more than six times as productive as non-IT labor. We also find that IT labor has a significant positive impact on the productivity of IT capital, but not on IT outsourcing. Further analyses reveal that in IT intensive industries IT labor significantly enhances the productivity of both IT capital and IT outsourcing, and a lesser such impact in non-IT-intensive industries. Moreover, dividing IT labor by wage levels, we find that high-wage IT labor has a significant effect on productivity, whereas lower-wage IT labor does not. More critically, although all IT labor enhances the productivity of IT capital, it is only high-wage IT labor that has a positive impact on the productivity of IT outsourcing.
