| This was mainly due to real wage rigidities and low interregional migration. |
| Evidence from the pattern of interregional migration between 1991 and 2010 also suggests that there might be a selective migration effect at play. |
| Note that, although there is in general low mobility, regions with a larger relative interregional migration in expansion are also the ones with larger mobility in recession. |
| His work involves constructing structural equation models to explain patterns of interregional migration. |
| Sorting effects cannot explain the scale of interregional productivity differences, while international migration rather than interregional migration has underpinned London’s growth. |
| In fact, interregional migration, the presence of out-of-range values and calibration can considerably affect estimates. |
