Casey Mulligan has tried to identify which workers if any were impacted by the increase in the federal minimum wage. His tentative conclusion is sobering:
For the time being, at least, it seems that increasing the federal minimum wage again would give a few workers a small raise — but at the cost of eliminating entire paychecks for the young, less educated and least skilled.
I imagine that there have been and will be other analyses of the July 2009 increase, which I’m eager to see.
