Optimal tax tax rates are lowered, revenue will be decrease by the same amount—and an economic effect—which provides incentives for individuals to increase their work output through low tax rates. These correspond to the mechanical and behavioural effects discussed by Saez. The Laffer Curve illustrates that, for sufficiently high tax levels, the (negative) behavioural effect will outweigh the (positive) mechanical effect of a tax increase, and so increasing tax rates will reduce tax revenue. In fact, tax revenue with a tax rate of 100% is likely to be 0, since there is no remaining incentive to work at all. Therefore, the tax
Notional election results local government wards, and it is the results from local government elections that are the primary source used to calculate notional results at a constituency level. Professors Colin Rallings and Michael Thrasher of Plymouth University have been involved in calculating notional results for general elections since 1992 where periodic boundary changes have taken place. The data compiled from their work has been used by several prominent media companies including television channels for the purposes of comparing one general election result to the last. Notional results have their limitations in that voting patterns may well have been different had new boundaries
