Laffer Curve Quotes



This is the most articulate historical statement of the modern conservative mantra regarding taxes. However, one change has taken place. The words “necessarily” and “often” tend to be left out of the more modern ideological statements. Mellon’s original statement has never really had any politicians or economists who disagreed. Politicians of all economic persuasions have generally accepted the Mellon statement but the extreme conservatives’ creed is that a lowering of taxes always produces more revenue and a tax increase will inevitably lead to greater tax revenue—a position which Mellon never took. Mellon however was very solicitous of the wealthy, felt the welfare of the nation depended on their prosperity, and was a strong advocate of what was later called ‘trickle down’ economics {628592}.


This inverse relationship between rate of taxation and revenue sometimes is referred to as the Khaldun-Laffer Curve or the Laffer Curve. However, Khaldun appears to by the first to document the relationship, David Hume, Keynes, and others have since. This quotation’s exact source is unknown and may possibly be a bogus quotation as it reflects a classic view of one of the partisan political philosophies. However, there are several references and for now we lean toward accepting it as authentic. Khaldun was one of the world’s greatest polymaths who among his other accomplishments was the “Father of Sociology” and was the leading Islamic intellectual of his era.


The Laffer curve was a mathematical, economic curve supposedly showing the relationship between tax rate and government revenue from taxes. In Laffer’s version of this curve, as interest rates go down, revenue from taxes goes UP because according to Laffer, there will be much more economic activity if taxes are lowered. In reality this has happened rarely in certain countries and in a very narrow range of tax deduction. As Chretien observes if you lower the tax rate to zero according to the Laffer curve this should maximize revenue but obviously it does not because with a zero rate there are no taxes collected even if the economy is booming. The Laffer curve was ideologically popular with those politicians wanting to lower taxes, but it never stood up to serious analysis and never worked in practice as Chretien observes. As a result, some people refer to the curve as the Laughter curve.
