Following up on my preceding post, I will here document who has said what.
High officials in the Reagan Administration apparently did subscribe to the Laffer Hypothesis:
• Reagan himself: “…our kind of tax cut will so stimulate the economy that we will actually increase government revenues…” July 7, 1981 speech 1/
• His Secretary of the Treasury, Don Regan, even after events had falsified the proposition to the satisfaction of most observers, wrote of his “very strong opinion that a tax cut would produce more revenue than a tax increase.”2/
Also: “The increase in revenues should be financed not by new and higher taxes, but by lower tax rates that would produce more money for the government by stimulating higher earnings by corporations and workers…” (p.173).
