This presentation is based on recent OECD work on Ageing, in particular:
The impact of Ageing on Demand, Factor Markets and Growth by Oliveira Martins, Gonand, Antolin, de la Maisonneuve and Yoo (2005).

The impact of demographics is gloomy: the number of people in working age per
retiree will decrease from 4 to 2…

Indexing the old-age threshold in line with longevity gains would only contribute to solve the ageing problem if aged workers…
– Remain in good health – Participate in the labour force and are
employed– Pension systems are reformed in order to
remove incentives for early retirement

With unchanged policies, ageing will induce an absolute decline in the labour force…
14
Labour quality may increase:
1. Younger cohorts are more educated than the retiring cohorts
2. Individual age-productivity profiles may stabilise at older ages.
Capital deepening increases labour productivity
Increased labour participation (especially older workers)
…but this decline could be compensated by some factors
15
Does the individual age-productivity profiles matter for aggregate productivity?

Ageing, Capital markets and Economic Growth

1. The “rising contribution rate” scenario: the PAYG system is balanced only by increasing contribution rates.
2. The “gradually increasing age of retirement” scenario: age of retirement increases 1.25 years per decade (as in population projections).
3. The “pension saving” scenario: replacement rate diminishing for new retirees, so individuals have incentives to develop private pension saving.
4. A comprehensive reform scenario: a combination of labour and pension reforms
Alternative pension and labour market reform scenarios

26
Key policy actions Increase employment rates, in particular of old-age
workers (cf OECD report on Ageing and Employment Policies)
Link retirement age to longevity gains Pension reforms improving the link between pension
benefits and contributions; check interactions with labour markets
Introduce pension funding Create new segments in the capital markets dealing
with longevity risk (annuities, reverse mortgages)
Complementary reforms are more likely to offset the impact of ageing than piecemeal reforms
