found: Shim, J.K. Dictionary of economics, 1995(Laffer curve. Named after a supply-side economist, Arthur Laffer, a curve showing a hypothetical relationship between the marginal tax rate and tax revenues. As the tax rate increases from 0 to 100%, tax revenues rise from 0 to some maximum level and then decline to 0. The optimum tax rate is the one that reaches the maximum revenue. Rates that are lower than optimum are regarded as "normal" since tax revenues can be increased by raising the rate. Rates that are above the optimum are viewed as prohibitive because they dampen incentives on the parts of businesses and individuals and are thus counterproductive)
