According to human capital theory, technological change will influence
the retirement decisions of older workers in two ways. First, workers
in industries with high rates of technological change will retire lat
er if there is a net positive correlation between technological change
and on-the-job training. Second, an unexpected change in the rate of
technological change will induce older workers to retire sooner becaus
e the required amount of retraining will be an unattractive investment
. We matched industry data on productivity growth and occupational dat
a on required training with data from the National Longitudinal Survey
s of Older Men to test these hypotheses. Our results support both hypo
theses.
