Despite the agonies of reform, the increases in pension age have not gone far enough. And, once they have been put up to a level that makes pension systems sustainable, they should be linked to life expectancy, so that from that point they rise automatically. As the OECD points out, such an explicit link is surprisingly rare (at present only three countries have adopted the policy, starting first in Italy, from 2015). Instead it is much more common for there to be an automatic link between higher life expectancy and reduced benefit levels.
