Letter from 180 Economists Sent to Congress

Say tax hikes would have a "significant, negative impact on the economy"

A letter signed by 180 economists opposed to tax increases as part of a fiscal cliff deal will be delivered to Congress on Wednesday, according to a national anti-tax group.

The letter argues that hiking tax rates would have a "significant, negative impact on the economy" and is slated to be sent to Capitol Hill on Wednesday, said Pete Sepp, executive vice president of the National Taxpayers Union, the low-taxes advocacy group that coordinated the effort.
