This paper explores the impact on older workers of new technologies that change skill requirements. Older workers, with older skills and less skills am prime-age workers, will suffer in comparison. Furthermore, if skill acquisition is costly, older workers have less incentive to acquire new skills because they have a shorter time horizon until retirement to recoup the investment.
Some surveys now report data on computer use by workers.
The age patterns suggest that older workers use computers less not simply because they are old or many years out of school, but because they are nearing retirement.
