THE recession of 2008-09 was remarkable in rich countries for its intensity, the subsequent recovery for its weakness. The labour market has also broken the rules, as new research from the OECD, a think-tank of mainly rich countries, shows in its annual Employment Outlook.

Young people always suffer in recessions. Employers stop hiring them; and they often get rid of new recruits because they are easier to sack. But in previous episodes, such as the recessions of the 1970s, 1980s and 1990s, older workers were also booted out. This time is different. During the financial crisis in 2008, and since, they have done better than other age groups.

The researchers focus on movements in “non-employment” as a share of the total population in three age groups between the final quarters of 2007 and 2012. This measure has the advantage of including not just unemployment, where people are looking for work, but also inactivity, where people are not seeking jobs. Whereas the average non-employment rate in the OECD has risen by four percentage points among young people and by one-and-a-half points among 25- to 54-year-olds, it has fallen by two points among the 55-64 age group (see chart).

Why have older employees done so well? In some southern European countries they benefit from job protection not afforded to younger workers, but that did not really help them in past recessions. What has changed, says Stefano Scarpetta, head of the OECD’s employment directorate, is that firms now bear the full costs of getting rid of older staff. In the past early-retirement schemes provided by governments (in the mistaken belief that these would help young people) made it cheaper to push grey-haired workers out of the door. These have largely stopped.
