Laffer Curve

named after US economist Arther Laffer (b.1940), the Laffer Curve refers graphically to notional/optimal government revenues according to changing levels levels of taxation, on the basis that at each extreme, i.e., 0% and 100% taxation, government revenues are zero, and that somewhere in between, a certain taxation % level (for which no general standard exists or can be applied) will produce optimal government revenues. The expression was popularized in the mid-1970s after reported discussions between Laffer and government officals Don Rumsfeld and Dick Cheney, seemingly in which Laffer sought to advance the counter-intuitive argument that lower taxation would increase tax revenues. Laffer attributed the underpinning curve concept theory to Ibn Khaldun and John Maynard Keynes.
