Our main result is that exposure to rapid technological and managerial changes does make a difference for plant productivity, less so for wages. In electronics, the Finnish industry undergoing a major technological and managerial shock in the 1990s, the response of productivity to age-related variables is first sizably positive and then becomes sizably negative as one looks at plants with higher average seniority and experience. This declining part of the curve is not there either for the forest industry or for industrial machinery. It is not there either for wages in electronics. These conclusions survive when a host of other plausible productivity determinants (notably, education and plant vintage) are included in the analysis. We conclude that workforce aging may be a burden for firms in high-tech industries and less so in other industries.On the more optimistic side, they do note in the paper that "older workers int eh future will be likely more educated than they are today and therefore, as also implied by our results, they may be more apt to deal with the Next Big Things."
