Arthur Laffer he learned it from Ibn Khaldun and John Maynard Keynes. A simplified view of the theory is that tax revenues would be zero if tax rates were either 0% or 100%, and somewhere in between 0% and 100% is a tax rate which maximizes total revenue. Laffer's postulate was that the tax rate that maximizes revenue was at a much lower level than previously believed: so low that current tax rates were above the level where revenue is maximized. Numerous leading economists have rejected the view that a tax rate cut of current federal US income taxes can lead to
Yerkes–Dodson law Yerkes–Dodson law The Yerkes–Dodson law is an empirical relationship between arousal and performance, originally developed by psychologists Robert M. Yerkes and John Dillingham Dodson in 1908. The law dictates that performance increases with physiological or mental arousal, but only up to a point. When levels of arousal become too high, performance decreases. The process is often illustrated graphically as a bell-shaped curve which increases and then decreases with higher levels of arousal. Research has found that different tasks require different levels of arousal for optimal performance. For example, difficult or intellectually demanding tasks may require a lower level of arousal
