It's always a little dangerous to enter an econ prof's turf and question his use of numbers, but, what the hell, I'll give it a try.
Charles North, an econ prof from Baylor University in Texas, entertained the House committee looking into whitewashing tuition tax credits with his study concluding that the tax credits saved Arizona somewhere between $44 million and $186 million in education costs just last year.
Mind you, his conclusions are speculation, by his own admission, and they're based on a study he wrote commissioned by the Center for Arizona Policy, a conservative, pro school choice group, which also paid North's airfare to Phoenix.
