Demand shocks have greater effects on local wage rates if the local unemployment rate is initially low, but lesser effects if local job growth is initially high. These different effects of local demand shocks imply that social benefits of adding jobs are two to three times greater per job in more depressed local labor markets, compared to more booming local la...
