Les salariés âgés sont-ils moins productifs?

The study assesses the development of productivity according to age through the various age-groups' contribution to firms' productivity. It increases with age until 40-45 then remains stable. There is no decrease in productivity towards career's end, at least not before the age of 55. Productivity profiles follow closely those of wages. There is no significant difference between productivity and wages for older employees except over the age of 55.Older employees' higher wages should not, therefore, be a major obstacle to their employment. However, this is an assessment of average productivity profiles and not individual productivity. Moreover the profiles are based on employees within the labour market, not on all individuals. We cannot, therefore, rule out the possibility of a decrease in productivity of certain older employees if these less productive workers had been ousted from the labour market.
