Following up my last post that suggested family stability inhibits labor flexibility, I might mention that in our own recent hiring experience at Chico State, an inordinate number of good candidates proved unemployable because of the need to accommodate a spouse.
In a similar vein, Andrew Oswald showed that home ownership is the most reasonable explanation for differences in unemployment rates between countries. His scatter graph has a very impressive fit, presumably because people with homes are less likely to pick up and leave for a new job.
