I don't know how you possibly could estimate that. You'd have to know how much they'd raise the minimum wage too. Then you'd have to know whether economic conditions are such that the increase could be passed along. Right now, raising the minimum wage from $7.25 an hour to, say, $13 an hour wouldn't make a difference because the job market is forcing employers to pay more than that for employees. The current minimum wage has been rendered irrelevant b/c of the demand for workers and that's a very good thing.
