At a briefing at the Economic Policy Institute on Tuesday, January 14, 2014, Jason Furman (Chairman of the White House Council of Economic Advisers), Sen. Tom Harkin (D-Iowa), Rep. George Miller (D-Calif.) and Lawrence Mishel of the EPI discussed the economic case for raising the federal minimum wage and the path forward to enact the Fair Minimum Wage Act of 2013.
EPI research shows (see here) the Harkin-Miller bill would give a raise to 27.8 million workers, who would receive about $35 billion in additional wages. A $10.10 minimum wage would increase GDP by $22 billion, creating roughly 85,000 new jobs.
Mind you, raising the federal minimum wage to $10.10 is meager...should be at at least $20.00, which would provide more than just a 'modest boost' to the US economy.
