Is unemployment in the developed world so low because people have simply given up on finding work? Ed Butler speaks to economist Danny Blanchflower of Dartmouth College, who says that a decade after the global financial crisis, workers in the US and Europe continue tp face a terrible jobs market that is not reflected in the official statistics.

Is the problem that all the well paid jobs are being created in a few rich, expensive cities that are simply inaccessible to the underemployed? That's the contention of Enrico Moretti, professor of economics at the University of California, Berkeley. And according to Christina Stacy of the Urban Institute in Washington DC, even within these cities, service sector workers are finding themselves priced out of the property markets where the job opportunities exist.
