Laffer curve at an intermediate rate of taxation, and then falls again to zero revenue at a 100% tax rate. However, the shape of the curve is uncertain and disputed among economists. Under some assumptions, such as revenue being a continuous function of the rate of taxation, the maximum illustrated by the Laffer curve is a result of Rolle's theorem, which is a standard result in calculus. One implication of the Laffer curve is that reducing or increasing tax rates beyond a certain point is counter-productive for raising further tax revenue. A hypothetical Laffer curve for any given economy can only be
John Brooks (writer) II and the ill-fated introduction of the most famous failed automotive gambit in history, the Edsel. Brooks also wrote widely on other subjects as well, including the government-guaranteed loans to Chrysler Corporation, the public television show "Wall Street Week" and its creator Louis Rukeyser, an examination of supply-side economics, the banking behemoth Citibank, economist Arthur Laffer and his Laffer curve, the development of New Jersey's Meadowlands, New York City urban planner Robert Moses, and even the Southern grocery store chain Piggly Wiggly.
