Unemployment in the US is high not just by its own past standards but by international standards, too, which is doubly strange. Figures also show a startling rise in long-term unemployment, to levels previously associated with Europe's broken labour markets.
In April the number of Americans looking for work for more than six months rose to 6.7m, roughly half of all those unemployed. Such a high proportion is unprecedented: the long-term share has previously reached a quarter at most. Terms for the stickiness of high unemployment such as hysteresis and sclerosis have preoccupied students of Europe's economies. They have not come up so much in discussions of US joblessness, but this may change.
Are these just signs that this recession has been exceptionally severe, or is something even worse going on? Can the US expect the rapid recovery in employment it has experienced coming out of previous recessions? On closer examination, US labour-market exceptionalism has not disappeared – but it is not what it used to be.
