Abstract :
[en] This research empirically establishes and interprets the hypothesis that the relationship
between population aging and inventive activity is hump-shaped. We estimate a reduced
form, hump-shaped relationship in a panel of 33 OECD countries over the period
1960–2012, as well as in a panel of 248 NUTS 2 regions in Europe over the period
2001–2012. The increasing part of the hump may be associated with various channels
including the acknowledgement that population aging requires inventive activity to
guarantee current and future standards of living, or the observation that older educated
workers are more innovative than their young peers. The decreasing part may reflect the
tendency of aging societies to lose dynamism and the willingness to take risks.
