What (if any) are the returns to computer use?

Using North American data, we revisit the question first broached by Krueger (1993) and re-examined by DiNardo and Pischke (1997) of whether there exists a real wage differential associated with computer use. Employing a mixed effects model with matched employer–employee data to correct for the fact that workers and workplaces that use computers are self-selected, we find that computer users enjoy an almost 4% wage premium over nonusers. Failure to correct for worker and workplace selection effect leads to a more than twofold overestimate of this premium.
