Gov. Sam Brownback of Kansas managed to slash state income taxes and the result was predictable: dramatic loss of revenue. The genius Brownback relied on was the infamous (or so I thought) ARTHUR LAFFER.
From Paul Krugman:
Two years ago Kansas embarked on a remarkable fiscal experiment: It sharply slashed income taxes without any clear idea of what would replace the lost revenue. Sam Brownback, the governor, proposed the legislation — in percentage terms, the largest tax cut in one year any state has ever enacted — in close consultation with the economist Arthur Laffer. And Mr. Brownback predicted that the cuts would jump-start an economic boom — “Look out, Texas,” he proclaimed.
