Austin Frakt asked how we can increase mobility during slumps. He flags a paper from Brookings with a solution that sounds an awful lot like Adam Ozimek's relocation vouchers:

The mobility bank could facilitate and speed up the moving process for some workers, increasing economic recovery in distressed areas. Ludwig and Raphael’s mobility bank would offer loans to individuals who want to look for employment in a new area or start work at a job already found. So as not to be burdensome for movers who found only lower-wage jobs, monthly loan repayments would depend on reemployment earnings. The mobility bank would be accompanied by increased use of national job banks that search more broadly for jobs to meet a given worker’s qualifications, illuminating the full set of options available to dislocated workers. With better opportunities available to them and a mobility bank from which they could draw loans, more workers may be encouraged to leave distressed communities. This could speed recovery in distressed areas by reducing the glut of unemployed labor and could have a positive effect on workers’ long-term earnings.
