Jobs are like marriages, says Lucy Kellaway. This is not just a nice point about lifestyle. It’s a great insight into economics. So great, in fact, that Chris Pissarides and Dale Mortensen won a Nobel prize for pointing it out. Employment, they said, requires that there be good matches between workers and employers, just as marriages require good matches between husbands and wives. A well-functioning labour market is one in which many good matches are made, an ill-functioning one in which matches aren’t made or fail.
